WSOL Account Keypairs

Question

I created a WSOL token account so I don't have to be creating temporary token accounts every time I want to make a transaction.

Thing is, I created that account using Python and the function that does this returns a WSOL_Keypair, which I did not store anywhere. Now that I have WSOL there, how can I use it to make transactions? I'm assuming I don't need the WSOL_Keypair because the function that closes the account doesn't use it as a parameter. But I'm not sure how to use the existing WSOL to make a swap, for example. Do I just sign it with the keypair from the main wallet?

Answer 1

When you create a wrapped token account or associated token account, you use the Associated Token Program to transfer wrapped tokens. You do not need the Keypair of the ATA, only the "owner" of the ATA has to sign. You specified an owner when you made the WSOL account.

In whatever web3 library you are using the ATA program's transfer is usually aliased token::Transfer or something similar to differentiate it from systemProgram::Transfer.
