This gap between what the display says and what is actually happening is why withdrawals started shortly before an exchange deadline regularly arrive too late. I measured the waiting times myself on September 14, 2026, directly against the contracts on Ethereum and against the public nodes of six Layer 2 networks. The short answer: on the optimistic networks Arbitrum One, OP Mainnet and Base, the finalized marker sits some eighteen to twenty-four minutes behind the current state, yet the waiting period written into the contract runs to between 1 and 7 days.
