Basic question about contracts

[jaconsjaco]

Hello folks!
When I look up a project on Coinmarketcap or other crypto lists something confuses me. For instance, It says that Elrond has a contract on the Binance Smart Chain, Cosmos has one on Ethereum, Cardano has one on the Binance Smart Chain. All of these I understand to be their own blockchains, so what does it mean that they have contracts on other chains?

It seems to be this way with a lot of other blockchains and some of the apps developed for a certain chain, e.g. Raydium on Solana. Some apps have contracts on a lot of chains, other apps or chains have no contracts listed.

I assume some of this is just Coinmarket not updating regularly. But what is up with the multiple contract thing? Why do chains and apps developed for/on certain chains have contracts on other chains?

Hope someone can enlighten me on this.

Have a nice day!

Some tokens developed within ETH chain. However, due to huge gas fee and less attraction they will consider to bridge into BSC or whatever they plan to adopt. It is for wider approach and catering everyone in different chains (advantage is important). Not surprising if you will encounter tokens with different contract address.

But did tokens like ATOM or ADA really develop on the ETH chain? They are the native tokens on their own chains, so I find this a bit strange.
