Why does the same transfer cost so much less on Layer 2?
Arbitrum and Optimism are both Optimistic Rollups, while ZKsync and Starknet are ZK Rollups.
Key point: Before transferring assets from Layer 2 back to the mainnet, check whether you’re using the official bridge or a third-party cross-chain bridge—the arrival time and risks differ.
$ARB is the governance token of the Arbitrum Layer 2 network.
Only invest what you can afford, and make sure you have a way out.
