[Doc] How to send a token? For example USDC

[mahnunchik]

Ok, the documentation describes how to send a native coin. But I did not find documentation on how to send a token, for example, USDC.

I chose USDC as an example token because faucet is working well https://faucet.circle.com/

Once again, it looks like the wallet implementation is making an unnecessary merge
https://github.com/MystenLabs/sui/blob/main/apps/wallet/src/ui/app/pages/home/transfer-coin/utils/transaction.ts#L49-L60

I think it would be a good idea to add an example of simple and logical action to the documentation, like sending a token.

Thanks, we'll try to add another example.

It would be good to also have a Move smart contract example for tokens like USDC. The current Forge/Sword tutorial could be extended to create a shop selling swords for SUI or USDC.

@rigwild that's a good idea. We have this for now, but definitely something in the examples folder would help.

@mahnunchik this could help with how to transfer USDC: https://docs.sui.io/guides/developer/stablecoins#token-sending-logic

@stefan-mysten Thank you! It remains unclear what to do if there are not enough tokens in coins[0] object.

@mahnunchik I am not sure I follow. If there are no coins, then you cannot transfer any object. Perhaps I am misunderstanding something. Happy to try to help if you have a more concrete example.
