First, a quick question: What is Layer 2?
In March 2024, Ethereum’s Dencun upgrade introduced blob data (EIP-4844), making it much cheaper for Layer 2 networks to submit data to the mainnet.
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 transfer time and fees vary.
$ARB and $OP are the governance tokens of Arbitrum and Optimism, respectively.
