Optimistic Rollups assume the submitted results are correct by default. During the challenge period, anyone can submit a fraud proof to dispute them.
When withdrawing from an Optimistic Rollup, allow roughly a week for the challenge period. Don’t wait until the last minute to use the official bridge if you need the money urgently.
The networks $ARB and $OP use Optimistic Rollups, while $STRK uses a ZK approach. Current rate: 0.1631.
