Multi-Withdrawal Transactions not Properly Recognized

[MSilb7]

Relaying a Multicall withdrawal only relays one of the withdrawals. The second one is unable to be relayed.

L2 Withdrawal (contains 2 withdrawals): https://optimistic.etherscan.io/tx/0x2a523f1b74b93f5d8c1bdc7e5a1d106e7b2c6b1e31c3449a370b05048fec5ada

L1 Prove: https://etherscan.io/tx/0x9e6871eded323816255827798b36ffb547df5ecb30b5b42b0a90b5020100bf5e

L1 Relay (only reads 1 of the withdrawals): https://etherscan.io/tx/0x217bf1d1abbb1805d586ff908373b928a7e63242d2505fd51ef52c5c8d1be4fb

Now, when I look up this transaction on superchainrelayer.xyz it says "Finalized," Etherscan also says "waiting" and I'm unable to relay the other withdrawal from the transaction.

Another example, seems like only the first indexed withdrawal gets finalized.

L2 tx: https://optimistic.etherscan.io/tx/0x7f10c777aa10550a35562c7960477fd70460e69a5aa9e10c022595eddc970bda

L1 relay: https://etherscan.io/tx/0xd1a29904ad2520bcd1b34ce8c86e94164fb6e334f3b6eea614d66298fad10ad8

Etherscan's relayer fails, saying the transaction has already been withdrawn; however, only 1 of the 3 has been withdrawn.

One potential solution for this would be:

• Update the relayer to fetch the tx receipt ourselves
• Using the logs on the receipt pull out all of the withdrawals https://github.com/wevm/viem/blob/main/src/op-stack/utils/getWithdrawals.ts
• Update https://github.com/wevm/viem/blob/main/src/op-stack/actions/getWithdrawalStatus.ts to include an optional withdrawal parameter to avoid making a breaking change. Right now it accepts a receipt and pulls the first withdrawal, this logic can stay unless the user provides a withdrawal.
• The relayer UI should be broken up to show all withdrawals based on the hash and show a status and actions for each one.

Viem now has better support for dealing with transactions that have multiple withdrawals. It's now possible for the relayer to support this flow.

const [withdrawal1, withdrawal2] = getWithdrawals(receipt)

// withdrawal1
const withdrawalStatus = await publicClientL1.getWithdrawalStatus({
    receipt: receipt,
    targetChain: optimism,
    logIndex: 0,
})

// withdrawal2
const withdrawalStatus = await publicClientL1.getWithdrawalStatus({
    receipt: receipt,
    targetChain: optimism,
    logIndex: 1,
})
