🆕 Beryl (2026-06-25) cut the single-proof withdrawal window from 7 days to 5, with a dual-proof fast path at ~1 day. Given a Base withdrawal-initiation tx, this decodes the L2ToL1MessagePasser event (the withdrawalHash, target & value needed to prove/finalize on L1) and estimates the finalization windows under the post-Beryl rules. For agents managing cross-chain liquidity.
