Today's key takeaway: Layer 2 networks
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 withdrawing assets from Layer 2 back to the mainnet, check whether you're using the official bridge or a third-party cross-chain bridge—the transaction times and fees differ.
Don't place an order just because everyone else is buying.
$ARB is the governance token of the Layer 2 network Arbitrum.
