      "summary": "Blast announced on 2 October 2026 that it is winding down its Ethereum L2 because operating costs exceed revenue. The normal Blast bridge interface works until 26 October 2026. After that, assets stay withdrawable, but only by interacting directly with the Blast bridge contracts on Ethereum L1. The withdrawal delay is being cut to 24 hours, after a pause of about a week while Blast unwinds its Lido position.",

        "Pick the asset. ETH arrives as ETH, USDB arrives on Ethereum as DAI, WETH must be unwrapped to ETH first, BLAST arrives as BLAST (Ethereum contract 0x71b9e0FD392713A14FCaB92D9aF7A21F47E3b1Fa).",
        "Submit on Blast (leave a little ETH on Blast for gas), wait up to ~1 hour, then Prove on Ethereum, wait the 1-day challenge period, then Claim/Finalize on Ethereum. You need ETH on Ethereum for the prove and claim transactions.",
        "Smart-contract wallets (for example a Safe) cannot use the bridge website; follow the contract-level guides in the Blast docs. Blast Mobile users have a separate guide."
