What is a Layer 2 network?
Arbitrum and Optimism are both Optimistic Rollups, while ZKsync and Starknet are ZK Rollups.
Layer 2s save money by bundling many transactions together and submitting them to the mainnet, so the mainnet fees are shared among many users.
$ARB is the governance token of Layer 2 Arbitrum.
Do not use this as a basis for taking action.
