Cryptocurrencies and their standards and networks

[garbagecoin]

How would you find out which standard a certain cryptocurrency is, that is whether the crypto is ERC-20, BEP-20 or something else?

Can a crypto belong to only one network? Where can you check network affinity? Must a crypto have different contract addresses in different networks? How can you check which crypto is the native token in a given network?

I think there are many ways to check this. The main one likely is coinmarketcap or other sites where you can search up cryptocurrency tokens and coins.

The most secure way, if you're using an exchange, is likely going to be to check what information the exchange has on it - they'll probably list the network at least and might give some additional information about the coin.

Can a crypto belong to only one network?

I do not think a coin can be operated on more than one network.

Where can you check network affinity?

A Google search of the cryptocurrency should reveal the network it is built on. You can use the suggestions above as well.

Must a crypto have different contract addresses in different networks?

I don't understand this question.

How can you check which crypto is the native token in a given network?

It commonly follows the name of the network, such as ERC-20; the 'E' stands for ethereum.

Another convenient way to find out is to ask the administrators in their telegram group or social media pages that's if the tokens aren't listed on tracking sites like coingeckeo or coinmarketcap. Tokens today exists on multiple blockchain, for example, the stablecoin USDT is operating on the Ethereum blockchain (ERC-20), Binance smartchain (BEP-20, Binance chain (BEP2), Tron blockchain (TRC-20) etc

Projects also have wrapped version of their token on other blockchain especially those chains that are widely accepted, they do this most times to ease the listing of their tokens on decentralized exchanges and for easier utility. Do not that some projects do this without authorisation like for example Bitcoin has its wrapped version on this other blockchain but you're not advice to buy those as they're centralized and isn't the real Bitcoin.

Must a crypto have different contract addresses in different networks?

That's not a must and it depends on how the other blockchain is structured, for example I have seen project on Polygon and Binance smartchain sharing same contract address. Do note majority of this other blockchain are just copycats of the Ethereum blockchain so they have similarities when it comes to addresses.

Where exactly is the network and standard mentioned on coinmarketcap.com? I'm sorry for being stupid, but I can't find the details.

Why does this page give Fantom (FTM) four different addresses and networks? (Click the three dots on the right.)

you first need to distinguish coins from tokens. Coins ^{especially Bitcoin} they have their own network, blockchain. so don't even look at him for it.

Check here, when you follow this fantom:



When you click on three dots in contract info, you get a complete list of which networks you can use to transfer that coin. Each network has a separate address for it so that the transaction is not lost between different types of networks.
It's not possible to send fantom ^{or any other token} through the Ethereum network (as ERC20) to Binance smart chain (BEP-20). I mean, you can send it, but they will not reach where you sent them.
there are no differences in the token itself, but only the difference in the network you use for transactions. it is very important that you understand this and always be careful when sending/receiving.

ERC-20, etc. are not cryptocurrencies, they are tokens. To know what type of token you are dealing with you have to check out the website of that token or its announcement on bitcointalk.

Any cryptocurrency (or a token) can only exist in a single blockchain and nowhere else.
However there are ways we can defined a secondary "network" where the same coin can exist in. For example bitcoin has only one blockchain and only exists there and nowhere else but it can have a second layer (such as lightning network) and same bitcoin can be used in that network.

This should not be confused with shitcoins that abuse the name of a popular coin. For example there are tokens available on shitcoin such as Ethereum that use the same name. These tokens have nothing to do with bitcoin even if they promise 1:1 swap rate and use the same name.
Same with tokens that exist on multiple shitplatforms. Just because the name is the same and exchanges swap them 1:1 doesn't mean they are linked. They are just completely separate tokens on separate shitplatforms (eg. on ETH, BNB,...) that are centralized and the centralized authority promises you a 1:1 swap ratio.
