thought about it, I'm down to do this for now but let's add a comment clearly flagging why we did this / what the impact is / indicating we may want to change in the future if we want to index multiple IGPs at a time

[tkporter]

getting a little hard to read, could we change the logic around here starting with line 249 to be something like:

if let Ok(mut sealevel_payment) = self.get_payment_with_sequence(nonce.into()).await {
  // Comment explaining why we do this
  if sealevel_payment.igp_account_pubkey != self.igp.igp_account {
    sealevel_payment.gas_amount = U256::zero();
    sealevel_payment.payment = U256::zero();
  }
  payments.push((sealevel_payment.payment, sealevel_payment.log_meta));
}
