solana spl token revoke authority of accountowner

Question

Blockquote

I would like to revoke all Wormhole token delegation permissions. I configured ChatGP and Python code as shown below, but it does not run. Transactions with existing permissions are as follows. Please help quickly.(https://solscan.io/tx/2uUX6Qr32XAfuD6Qm6ZJvBAJGqJmACgGyHoc99XMVU1i9qUB6nhAoucs8ApXVzagLUYVZcD1iGUu6Ab38YrB2eKY)

Your code sample is calling transfer with the token client and then trying to add it to a transaction, which is incorrect for two reasons:

• you want to revoke, not transfer
• the token client will create, sign, and send the transaction for you already

Instead, you can just do:

def revoke_authority(token_client: Token, account_address: str, key_pair: Keypair):
    try:
        token_client.revoke(account=Pubkey(account_address), owner=key_pair)
    except RPCException as rpc_error:
        print(f"Revoking authority failed: {rpc_error}")
        exit(1)
