With fault proofs activated, users can withdraw assets from L2s like Base or Optimism to the original (layer-1) Ethereum blockchain without relying on any centralized entity. This novelty, however, introduces certain changes to the process of withdrawals.

What’s changing to withdrawals on Base?
Following Base’s fault proofs’ implementation on the mainnet, withdrawals will involve proving and finalizing based on the fault-proof system.

Withdrawals before the upgrade will have to wait for a seven-day challenge period before finalization, while the fault-proof system will prove those taking place during or after the fault-proof upgrade. According to Base, this process usually takes seven days to finalize, but additional delays could occur if challenged.
