I created a solana wallet(lets call it deposit_wallet) and assigned the ownership of this wallet to my program 59JNYpGZ5sMoQzuUzMmCfqMzQncYc9Xjo6wgGgnZvcHw using SystemProgram.assign.

Now I want to implement an instruction in my contract to transfer lamports from this wallet owned by my program to another of my wallet receiver_wallet.

Here is the code I am trying

from seahorse.prelude import *


declare_id("59JNYpGZ5sMoQzuUzMmCfqMzQncYc9Xjo6wgGgnZvcHw")


@instruction
def process_payment(
    authority: Signer,
    deposit_wallet: Account,
    receiver_wallet: Account,
):
    deposit_wallet.transfer_lamports(receiver_wallet, 100000000)

The error I get:

❯ seahorse build
