They’re all Rollups, so why does withdrawing to mainnet take a week for some, but not for others?
L2BEAT classifies Rollups into three stages—Stage 0, 1, and 2—based on criteria such as their proof systems and whether users can exit on their own.
Before using a Layer 2 network, check L2BEAT for its Stage rating and risk warnings. The higher the stage, the less you have to rely on the team.
$ARB and $OP use Optimistic Rollups, while $STRK uses a ZK approach.
