Sidecar: check user balance and nonce before sending commitments #102

Open thedevbirb opened 5 days ago

thedevbirb commented 5 days ago

In the context of the recent proposal of account abstraction it may be possible that a transaction changes the balance of an EOA without increasing its nonce, since it can be originated by another entity. As such, in the sidecar we should:

wait for the right slot before sending the commitments and
check both balance and nonce according to the current state

@namn-grg another thing to research in the AA report is which incompatiblities there are with Bolt as of now

Actually some balances checks are already implemented, see unstable branch as of now: https://github.com/chainbound/bolt/blob/025d296a8c20b2fb6fb8d5d48c72b713abfd8067/bolt-sidecar/src/builder/template.rs#L86-L116 Moreover, such logic has been a bit refactored by #117 as well.
