Fake Tokens

[crzy]

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.

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.

[Atang Sulaeman]

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.

[noorammak]

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.

[fahmimajannat]

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.

[terrorJR]

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.

[ene1980]

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.

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.

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

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.

[makishart]

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.

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.

[Rengga Jati]

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.

[raes]

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.

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.

[ecnalubma]

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.

[Yatsan]

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.
