Fake Tokens

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.

[livingfree]

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:

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

[JeromeTash]

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.

[asriloni]

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

[danherbias07]

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

[LibertyShire]

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.

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.
