Let's assume i have created a game, and then created ERC tokens (Example swords) so the player must buy a token to be able to play the game.
What if someone creates similar tokens in his wallet and injects them into my game as if they are bought from my tokens store ???

This is not technically possible, a token has an address, you cannot mismatch 2 tokens or that means you don't know how to program your shop.

There's a contract address and it cannot be copied. He might copy the name and the ticker but not the contract address.

Your game must be familiarized the contract address where the token is coming and if it's not coming from that address even with the same name and ticker, it won't be read by your game.

I wrote a guide on this topic:
(GUIDE) How to trade on uniswap correctly
https://bitcointalk.org/index.php?topic=5270415
Typically, tokens are traded on decentralized exchanges, so check smart contract addresses. And the names of tokens can be the same
Watch the liquidity carefully so as not to buy at a high price.

the contract address will not same from each token mate, so you don't need to worry about that
maybe someone can create the same name with your token, but not with the contract address buddy

The difference will be the contract address. The token symbol, name or supply might be the same, but the contract address will always be different. Just like DNA is unique to each human being and can be used to identify one, so is the contract address. So as a developer or founder of the project, It's your duty to warn users to always look out for fake tokens by verifying if the contract address is the correct one.

On Uniswap and other decentralized exchange, there is a warning about token imitation every trader should check the contract address of the token because it is the only way to know that you are trading the right token, it's the traders or investor's fault if he failed to check it and got scam by a fake token, it's the duty of all investors and traders to make sure that they are dealing with the right contract address.

No it cant be possibly happened knowing that each coin does have specific address/contract.They might create another one but its easy to distinguished between the real and fake one.

So many centralized exchanges are also offering contract addresses with the name of an ERC-20 tokens. Your ERC-20 tokens will be lost if you deposit other contract address tokens in your provide deposit address. I lost my one ERC-20 tokens. Only newbies can think that this is a problem. Even this post isn't a part of altcoins discussion post.

There are swapped tokens in the market but it did not create confusion, the contract address is the key to find out if anyone is using a fake token on your website, you can issue a warning if you find out that there is a similar token like yours, it's anyone one's fault if he bought a fake token there are warnings on DEX about fake tokens and about checking the contract, if you overlooked it then it's your fault.

That will be based on what smartcontract address that already integrated with your game. It will not possible to inject the fake token in your game. If the game already programmed to processing the token based on your smartcontract address and then another token will never able to be used to play your game.
Your smartcontract address just like an identity for you dude.

If you were programming your game properly and it would not possible. That totally depends on how good you are connecting your game to your smartcontract and then use your token as a currency to play your game. This must be on the back end programming. If you are having good implementation and then the fake token will never be injected into your game.
it's easy to know which is fake and real smartcontract.

Thats impossible if the platform only were able to read smart contract the game designert that has been program. Yes they could make fake tokens but real projects with use case doesn't even tainted with a copy pasted gaming blockchain.

He can have fake one or fool some on trading byy not in the use case of a project. People should always check if they have the same contract address

They're all correct. It's the contract that cannot be duplicated. It's like a private address that is unique.
The other difference is the ticker. If I am not mistaken, you cannot also have a duplicate ticker. You will need to change a single letter or put a number.
It's not different with mutual fund investment, everyone is trying to give their projects a unique name and code.

If they will try to inject something on your project then it will mostly be a hacking system. It will be the worse thing to happen if you won't have any security.

You aren't a developer so you don't understand what it means to have a smart contract address for your token, this way no other token can merge with yours because smart contract will always be different, it's just like every public addresses

Since everyone is emphasizing on unique token address, now to be crystal clear:

Let's say i have issued 100 Gaming different swords  each with unique attributes such as (attack value, power etc...)  in this case every item will have its own unique address, now based on the repliers feedbacks the solutions seems to be as follows:

After creating swords (NFT) tokens  the addresses of all created tokens should be saved in a database on the server, and then when the players tries to bring a sword into the game the system should check it the token's address is one of those addresses stored in the database.

ERC is an eth base token with a smart contract, people cannot manipulate it like that. If indeed someone creates a token with the same name, but he / she will not be able to impersonate the smart contract address.

it is Not possible because of the uniqueness of wallets in each coins so impossibility that another person can create a coins similar to yours and just put it inside your game.

it is Not possible because of the uniqueness of wallets in each coins so impossibility that another person can create a coins similar to yours and just put it inside your game.
[/quote]

Nut when the player buys the token , it will be transferred to his wallet !!! I assume you mean that; i should track down the address of the token creation rather than the  current address that the token resides in.

Indeed you must mate, that will only the best way to keep safe your game/Site.

I assume that you are interested to create a gambling game yes?

He was asking for answers, he did not even pretend to be a developer lol.

That's right they cannot inject that specific token to your network, but those scammers can use your token name to scam people using a different contract address. This is why investors are being warned of so many fake tokens on DEX, better to create a unique token name and a good logo so the players can know if they are buying the real token or not, since anyone can create token on swap exchanges.

That will not happen, Each coin has a unique smart contract that there will be no duplication. Maybe names can be likened, but data data such as smart contracts, websites, communities I'm sure must be different and that's what makes cryptocurrencies can not be equated to the creation of the previous

Maybe some people less thoroughly cause wrong address, some people will certainly also try to cheat with the name that I have with a different address. If it's less thorough it would be like creating a fake token. Keep your data correct by checking coinmarketcap and CoinGecko.

Like others already mentioned: Every token that is created has a unique contract address that can not changed after creation. Token names and tickers can be duplicated though so always look at the contract address if you want to interact with a token. This is especially important, if you want a new token that just started trading on uniswap or pancake swap because almost every time there are scammers that create a fake token with the same name (but different contract address of course) and are hoping for some unlucky guys that are buying their tokens instead of the real one. So always double check, if the contract address is correct.

Items in your game have a contract address. and the game will only respond to the official contract that you register. I don't think it's possible for someone else to inject or copy them all.

it looks like there won't be 2 tokens with the same address and contract. be more thorough before transacting due to fraud with the same name but definitely different addresses and contracts. and that is where our foresight is before transacting or sending a token.

Contract address is unique it is for your project game. If scammer will create the same token and the same name, he cannot copy the same contract address. Because it is technically for you alone. Scammer will copy cat some details but still the Authentication is unchanged. For investors, they should take extra careful to find out the correct one so they can avoid scam token.

The creation of a forged token is possible but it cannot be deposited into the game because the smart contract of the in-game exchange token is unique. That is the unique point of blockchain technology, which cannot be faked. If you do a P2P exchange of ERC20 tokens, carefully check the contract before trading.

There are lots of fake tokens in the market.
So traders and investors should be aware of these kinds of tokens.
Always do YOUR own reasearch while investing don’t depend on others predictions.

names may be the same but our addresses will not be manipulated because each address will definitely be different cannot be the same. Indirectly, if you have set the address you have prepared and applied in the game that you make automatically only one can and the other address cannot or in the sense that it will be immediately rejected by the game system that you created.

In waves you can have the same ticker and if you were not careful there is a possibility that you get scammed and there were many that got scammed during that period. So you need to be careful when purchasing any token and the most important part is the contract address.
Even in uniswap anyone can create a token and all you need is liquidity to look legitimate and hence it is possible that you might fall for fake tokens as well, personally i am yet to use them.

You cannot inject anything unless you did some blunders while coding and no one hacked the blockchain :P.

Which is right, it can't be replace or duplicate contact address is a unique identity of each coin/token that beng created inside the system.

Scammers  can do duplicate identities and old those valid information but in the sense of unique adresses it can't be duplicated.

You need to make sure doing your research in anyhow just to make sure to prevent or avoid
those scammers around.

The thing is, if the system is not checking what you are doing correctly, it would still not be the same masterchef and it wouldn't work. However you could potentially face people who will make things that look like yours and then sell it to people and then people will pay while getting a fake token.

It wouldn't work inside the game, but it would work outside, after all it is crypto so the scammer would say "I will send it to your metamask" and that will work that way whereas what he sends will not be the real thing and then when you pay them it will be too late when you realize it is fake. Obviously not that many people will believe this and it will end up being nothing serious but at the same time we are talking about something that could happen for a few people for sure, I have seen so many people getting scammed that I am sure "give me money and I will give you more" is a valid scam method for quite a few people.

It not possible for anyone to create another version of the token you created and inject into your game but someone can still create a token that have the same name to your created token or possible the same ticker and use it to make believe it your own version of coin in the market.

Any item should have different uniq numbers. I think that you can see the implementation of NFT game like axie infinity, vulcan forged and some dapps game.
When someone wants to buy a sword and that guy must buy that and then some tokens as proof of ownership will be sending to the unique address that owned by the sword.
After his transaction gets confirmed and then the system will detect the sender and receiver address.

You may not need to worry about it.
As what have been said by members here,  every token has its own contract address and it will never be the same.  It will be unique and different for all tokens.
They may be able to create similar symbol and decimals and use your website to support that fake token,  but the fake tokens can never be deposited or added into your original token because they have diffefent contract address. 

There are many examples about fake tokens.  But still many people become victims buying those fake tokens.

this way that is often done by scammers to make a profit. especially for new projects that are having an event before their token is traded. sometimes buying and selling transactions between members of the crypto community on social media have occurred. we can even see them selling at a very low price.

Smartcontracts are unique and it cannot be replicated. So even if bad actors will create a fake one your game should have a unique mechanism to reject it and only accept the genuine token. Its a standard procedure for most project and developers to warn users to verify smart contracts before they make purchases.

Newbies will be the ones who will get lured by those fake tokens then mistaking the fake ones to be a legitimate one if they will just consider looking by the name of the token itself. But for an experienced person in cryptocurrency who always looks upon even the very small details of the token, surely they will spot the difference between the contract address because they are unique for every token. The key for them not to get deceive is to simply be observant and do their research well before doing engagement.

Did you lose your tokens with the same name during the deposit of the tokens? Decentralized exchanges are free for this problem. But I lost my tokens for the same name. Very few centralized exchanges offer deposit addresses without a contract address. But one thing is clear fake tokens can't be created by any scammers.

From what I know, I don't think this is possible, he can copy the name of the token including the ticker, but definitely not the contract address it's just not possible, as far as the contract address are not the same the other persons "swords token" won't work on your platform, so don't panic nothing of that manner is going to happen.

There are thousands of abandoned fake tokens in the crypto space, since it's free to create a shit token as long as anyone know the programming language that is required, in your case there's no need to be worried, since every token has their own smart contract which they work on, since the smart contract of the other token and yours are not the same then, the fake token cannot be used in your platform even if they bear the same name.

Of course you can't because it will have a different contract with only the same name, so people will definitely be careful if they want to buy nft with the same name. Some people may be fooled because some neglect and do not check the address contract, but can not change the contract address that you made.

Actually there are some differences that we can examine, there are contract addresses, which have similarities only in symbols and names and supplies, because the contract addresses will always be different, it is one of the developer's tasks to alert users to the threat of fake tokens by verifying the address original contract.

He can copy token symbol, name they can be same. but the contract address is unique and always different. This is why investors are being warned when they buy or sell to make sure that they are dealing with the right contract address.

How can they inject that on something you have full control of if your store is using  metamask and your wallet and your games are integrated then it's impossible to integrate into your project, but they can do that on an exchange so it's recommended to remind your buyers and players to look on the smart contract when buying and use the smart contract when adding your token in the metamask extension

Erc20 token has its own smart contract address that you can identify with, for someone to use a fake token they need to take control of the game you created and if they happen to have that control then it safe to say that it isnt your game anymore.
You gonna be fine and thats reason why many projects recommend to take a look at the smart contract address to see whether its correct for precaution.

I don’t think that it is possible. The standard ERC721 that is used for tokenization of different things in games, assumes that this thing is unique and has its address, so it’s impossible to create the same thing with the same address.
Moreover, I think that if you are able to create a game then you can set it up in a way that it will not accept things that were not bought in your shop. But actually this way the logic of NFT-tokens will be destroyed, because they assume that players can use their tokens in different games.

It can't be done, if you haven't set up your own rules in the game, meaning if someone tries to create a similar token in their wallet and then injects it into your game it will automatically exit the command in the rules you created.

For example issuing a verification command for an account that starts to log in and is suspected, otherwise the game you create will not be safe for people to play, logically the game maker itself cannot restrict people from trying to enter the game without the owner's permission.

How can people trust your game, every application that is created automatically must have its own security level and it is not easy for others to try to tamper with the application/game.

I think when you intend to make a game, the first step that needs to be prepared is the level of security, otherwise the game you make does not mean anything to people or people will not play the game.

Yes, but not all of those who are in this forum are programmers, so most people don't know what to do in order to be able to falsely determine each coin and address, because scammers are also very smart in circumventing this now.

This is the function of a smart contract, it can't forge your token. If someone creates a new coin with the same name, same decimal, even with the same code, they also cannot deposit to a platform with a different smart contract. Understand the meaning of smart contracts, so you don't have to ask about this anymore. There are many fake coins circulating in Ethereum smart contracts, BSC, but they can't have any effect on the official coins. It's just that they can fool people who don't understand smart contracts. If you want to deposit any coins, the first thing you need to look at is the smart contract, then the blockchain used. If different, do not do anything, because it will lose your assets.

Even though there are some who make similar tokens but it still won't work against the games you have created because each token has a different contract address

the easinest creating token in any smart contract platform used by fake dev to trapped investors and buying this token. in many group especially when project will launched IDO , this fake token will occur and many investors be the victim. more over i see there are programmer provide their services to create our own token with low fee.

it working in IDO project dude, scammer will spread their fake token in TG that will have IDO  in near time. Just look at moonpot IDO , scammer spread that their fake token in group and unfortunately many investors be victim.

The name or symbol of the tokens may be the same. and they can also list on certain exchanges. But, the smart contracts will be always different, there will not be the same smart contract in which we can check them. That is why it is better to put your smart contract on your website or other information channels.

So far there are many fake tokens that we can find especially in the new exchanges or not reputable exchanges. that's why before buying any tokens it is better to check them on their group officially to ensure the smart contract and also check on the coin market cap.

Yes your name can be taken  and some newbies or friends without crypto knowledge might buy the tokens of that person thinking it's you.
But anyone in the crypto space will know cause they will go through your company's info to check your contract address and check that of his now we that case is solved
I don't even think someone can just wake up and still your game in this way. only if you have no contract address which surely you do.

It's okay when you have the ability to create ERC tokens (Swords) and this is not prohibited in the increasingly sophisticated world of technology, actually it looks good and interesting for the advancement of every available resource.

If someone generates a similar token and then injects it into your game, then the thing you should do to avoid this from happening is to set up a good game security system before you release it.

this security system should be able to detect intruders who start supplying similar tokens, meaning you should have access to deny those tokens to your game. If not, the game you make will not be an interesting game for people to play.

This is why if the OP doesn't know how to integrate that in his online shop, he needs to hire a developer that will program the correct contract address. So if a user tries to send fake token, it will not go thru. It is just a matter of coding not to be screwed by scammers. Contract address is very important to identify it from fake tokens. We have seen that a lot especially if the token is getting popular.

Of course this will not work because each token has its own contract. The game will run like that, every item in the game will have their own identity associated with the game address contract.

You have a unique contract address which you need to announce to your players that they need to double-check the details before they convert or buy tokens from the exchanges. This is becoming the norm and most of the NFT games right now have their own counterfeit tokens. You need to be aware of it especially in the early time of introducing your games. You can also look for the answers on the existing NFT games on how they tackle such problems so that you will have an easy way to avoid bad things to happen in the future.

Yes they won't get confused because each token have unique contract address, people usually get tricked buying the wrong token on the market because they have the same symbol or even the same name. So becareful of buying tokens, look at the volume first, then make sure the contract address is already true because if we take a quick look we won't realise the contract address is different so pay attention to it's details

That's not possible. I think play to earn crypto games will be big though.

there are lots of fake tokens in the market be aware of these

This is not possible if you prepare a good security system, something that is made must be based on an integrated security system and is in direct contact with game or network makers.

If not, then the game we make is not the best solution for people to use, how can people trust the game, if we can't maximize security alone, this is why making games is not an easy thing and can be done by people.

There are might be imitators who will launch your ideas as if it is their own.  It might also be possible that someone will create a token and name it exactly as yours. What is not possible however is someone injecting their token in to yours or the services you provides. This is not technically possible!

each token has a different contract address and it can't be copied, no matter how similar the name or even the logo used will still have a different contract address if it's a clone, so there's nothing you need to worry about, you just need to write down the contract address that original and if you find a similar token, you just have to check the contract address.

Contracts are different and if you do try to deposit out coins/tokens which are in different then it would be still useless since it wouldnt credit out and this is the beauty of blockchain technology.
You are just imagining too much or simply doesnt really have the slightest idea or knowledge on how blockchain works.If you do then you would say that this kind of question is a little
bit senseless but since its isnt really bad to ask then its still a considerable one.

Each token has its own smart contract, it must be different between your token and another token. So, there is no chance for someone to create a similar token and use it to play your game. You can identify it easily by analyzing its smart contract. I think you don't need to worry about this because it is very clear that you are safe with your own token.

In this present world that we are in presently, lot of things are happening and the cryptocurrencies has also open the eyes of so many to a lot of things. Token when accepted turned into a digital currency, and will have fake paper note so also will should expect something like fake token too. Some people are just somewhere always looking for opportunities to defraud other people of their hard earned money. But that is why the Blockchain is one of the most secure space, it is so safe that there is not space for an intruder. Each coin has its own unique contract address, which can never be bridge. They can develop another token with similar purpose and even look alike, but the contract address will always be different.

im about to say this . never saw the same contract address so every contract address should be unique .

if we code the game well , it will be hard or its not possible for hackers to attack it and when theres someone attempting to mess up the game ,
 they will be punished accordingly . they will think twice if they will do such act or not

Each coin has its own contract, so it is impossible to create the same coin. I admit the possibility that someone will make a coin that has the same name and a participant in your game can buy it by mistake on a decentralized exchange. But he will not be able to introduce such a coin into your game later, since it will have a different contract.

I'm not an expert regarding the coding of smart contracts but to create a faked tokens base on the original name and Ticker is possible, but let us accept the fact that both tokens have run on different smart contacts that's why its not possible to bind them together and run both in one platform

These games have tokens and each token is matched to a contract address. No two tokens have the same contract address. A contract address is like the address of the token on its own Blockchain. So its not a feasible act. I daresay 100% impossible. So try another exploit sir

Well it will not detect the fake token of your game because the coin has own contract address and the fake token has also contract address so it will not determine as a coin of your game even both are very similar like the name and the logo but the contract address will not be copy, every coin has unique contract address.

First time when crypto comes in market so many traders takes advantage of that and market is going till now very well but there are some people who making fake token and sending to bsc, polygen wallet not in eth wallet. Please beware of these tokens. They are sending these tokens in large numbers. I don't understand that how these mens will survive in this world who are always others money, not looking to do a legitimate job.

Even you are expert but still you are not aware with this it's not possible to create fake tokens because if you are doing all things properly, and you are good at programming then no one can do this all. I am not expert, but I feel that never have any duplicate ticker because you need something difference, even just a smart word or anything.

Every ERC token is working with his own smart contract, so if someone tries to take control, then you will identify this all very quickly.

Those who are cought in those kind of scam are either gullible or they don't care to know more about scams. If you check carefully, most of those tokens are always given out inform of Airdrops but I detest anything that's free.
Those tokens are created to steal your bnb if it's bsc or Ether but mostly it used to be BSC since it's always cheap to transact. The moment they sent you those random token and you decide to swap them, the smart contract will make execution in a way that it will take all your bnb.

You can also check this thread for similar reports  HERE (https://bitcointalk.org/index.php?topic=5350998.0)

Easy for BSC, Polygon, HT network to get scam and fake token on every transaction, maybe with lower gas fees scammer not worry with how much fees pay for sending their fake or scam token. You can track with your bsc address every time after success make transaction for sending coin you will received new token and most probably with scam coin in your address.

Its very easy to verify the fake tokens. Just verify contract address of that token. Because two tokens can have the same symbol but not the same contract address.

Once a contract address is assigned for your so called project, the same exact address can never be generated for another project. So that address is what you give out to anyone who wished to invest into your project.

Well it may be possible for a token to have a similar name or a fake version but the contract address can not be the same as one address can't be used for two versions of coins, it's technically impossible but we have seen cases of such incident but mostly on the uniswap chain.

Exactly!

But people are way too lazy on checking things up neither they dont have any time to do it or simply lazy or simply doesnt really know on whats contract address is or simply doesnt have any idea on what things been happening.

This is the main issue for some because you cant really be scammed if you do just make use of your common sense.From checking the dev team legitimacy to contract address differences.

It isnt really that hard to avoid yourself on potential scams or simply with fake tokens if you are really just be mindful in regards into your onward actions.

When I check my wallet on blockscan BSC, Polygon, HT there are always tokens that are so foreign and I don't think it's useful, I know that tokens are fake but scamers will target beginners to transact next of course this will make them wonder why they can get tokens , even though it's fake.

The most important thing is that we must understand how to distinguish the contract wallet, it will always be different and find out which one is the original and we can tell the difference.

I think in every transaction I make the scamers send fake tokens with no idea what the purpose is.

To see the fake token is very simple, I found that just if you look closely, you will see that the contract address is different from the real project. Any fake token can be imitated in name, website... but can never fake contract address, which we all can easily recognize. And if you're programming your game properly, that won't be possible. That depends entirely on how well you connect your game to the smart contract? What about experience and knowledge?.
