使用其他费用付款人进行 SOLANA spl 代币转账

Question

I was actually developing a token in SOLANA Blockchain and stuck in a place. The problem is.

I need to transfer a custom token ( Eg: MyCustomToken ) I created ( Not SOL ) from one wallet to another and charge the gas fee from another wallet. So the process is,

Wallet A : The token Sender Wallet B : The token Reciever Wallet C : The Fee payer.

I saw that it is possible with --fee-payer argument in the case of SOLANA, but I haven't found a way for Tokens I created. Is there a good solution for this? Please help.

Thanks in Advance

Answer 1

The spl-token CLI has the same --fee-payer argument that you can use to set the fee payer, AKA "Wallet C" in your example.

If you're using JS, you'd set it when sending your transaction, ie:

await transfer(connection, walletC, walletATokenAccount, walletB, walletA, amount, []);

Note the payer argument specified as walletC : https://github.com/solana-labs/solana-program-library/blob/2ad468f8b751e819dd68007064495ce2e69ff863/token/js/src/actions/transfer.ts#L18
