1. Unclaimed OP Mainnet or Base withdrawal

   Optimism, Base

   $64 · 2 positions

   You withdrew ETH or tokens from OP Mainnet or Base to Ethereum but never did the last step on Ethereum. The funds wait in the bridge contract.

   1. OP Mainnet: open the Optimism bridge (app.optimism.io/bridge), connect the receiving wallet, open your withdrawal, press Prove, then Finalize after 7 days.
   2. Base: Base's docs list Superbridge and Brid.gg as its bridges. Open one, connect the receiving wallet, find the withdrawal, press Prove, then Finalize.
   3. Base waits 5 days after Prove (1 day if both a TEE proof and a ZK proof back it). Pay the Ethereum gas fee each time.

2. Unclaimed Arbitrum withdrawal

   Arbitrum One, Arbitrum Nova

   $28 · 2 positions

   You withdrew ETH or tokens from Arbitrum to Ethereum but never did the final claim on Ethereum. The challenge period (about 6.4 days) is long over, so the funds can be claimed now.

   1. Open the Arbitrum bridge and connect the receiving wallet.
   2. Open Transactions and find the withdrawal marked Claim, or paste the withdrawal transaction hash.
   3. Press Claim and confirm. You pay the Ethereum gas fee. The funds go to the recipient.

3. Nucleus vault shares

   Nucleus (BoringVault)

   $7 · 3 positions

   Nucleus deprecated its vaults on 19 Dec 2025 and the withdraw page is gone. You can redeem vault shares through the Teller contract, but only for assets the vault still holds.

   1. Read the Nucleus deprecation guide first.
   2. Check which tokens the vault still holds, and your vault token balance, on Etherscan (or the Plume explorer).
   3. On the vault's Teller contract, Write tab, call bulkWithdraw(withdrawAsset, shareAmount, minimumAssets, to). The guide says to use 0 for minimumAssets.

4. Archived L2 bridge funds

   Archived L2s

   $5 · 2 positionsMay not work

   This chain shut down and its state is gone, so no one can prove a withdrawal now. The Ethereum bridge still holds the money; only the chain team can release it.

   1. Use the official bridge of the chain you withdrew from (linked next to each of your positions).
   2. Check that chain's official site for a refund or recovery notice.
   3. Without the chain's final state nobody can prove a withdrawal. Only the chain team can release the bridge funds.

5. Mooniswap (1inch) LP tokens

   Mooniswap (1inch AMM, Ethereum)

   $5 · 3 positions

   Mooniswap was a 1inch exchange on Ethereum. Your LP tokens give you a share of the tokens in the pool, and the pool can still pay out.

   1. Find your pool with getAllPools() on factory 0xbAF9A5d4b0052359326A6CDAb54BABAa3a3A9643 (v1) or 0x71CD6666064C3A1354a3B4dca5fA1E2D3ee7D303 (v2), and open it in the explorer.
   2. If the LP tokens are staked in a farm, unstake them first.
   3. Call withdraw(amount, minReturns) from your wallet.

6. Alpaca v1 vault tokens

   Alpaca Finance

   $5 · 2 positions

   You hold Alpaca v1 ibTokens (deposit receipts) on BNB Chain. The vault still pays out the underlying token.

   1. Open the ibToken contract (contract column) on BscScan and go to Write Contract.
   2. Connect the owner wallet and call withdraw(shares).
   3. ibBUSD, ibETH, ibBTCB and ibUSDC were migrated: withdraw may pay a different token. If it reverts, read the contract's functions on BscScan.

7. Polygon zkEVM balance

   $3 · 1 position

   Polygon zkEVM's sequencer stopped on 1 July 2026. Wallet-held funds not bridged before then can be claimed on Ethereum in a claim UI. Polygon treats unclaimed assets as abandoned after 2027-12-31.

   1. Open the Polygon zkEVM claims site and connect the wallet that held the funds.
   2. Pick your balances and send the claim transaction on Ethereum.
   3. Funds locked inside DeFi contracts are not auto-migrated. Ask Polygon through the forum post.

8. dYdX v3 balance

   $2 · 1 position

   dYdX v3 was shut down and its exchange was set to 'frozen' on Ethereum. Your USDC can still be taken out through the escape hatch, or withdrawn if already released.

   1. Open dYdX's v3 sunset post and use the Escape Hatch link in its last update. It is hosted by an independent third party.
   2. Escape needs a proof for your stark key and position. The page builds it; the escape call goes to StarkPerpetual 0xD54f502e184B6B739d7D27a6410a67dc462D69c8.
   3. Then call withdraw from your registered Ethereum address to receive the USDC. You pay Ethereum gas.

9. zkSync Lite balance not claimed

   $1 · 2 positions

   zkSync Lite was shut down on 2026-05-04. Remaining balances are claimable on Ethereum through a claim contract and a withdrawal portal. Your account is on that list and has not claimed.

   1. Open the zkSync Lite withdrawal portal and connect the wallet that owned the account.
   2. The portal finds your address in the final state, builds the proof and sends the claim. Follow its prompts.
   3. Confirm the Ethereum transaction. Tokens go to your L1 address. Matter Labs sponsors gas for the first 100,000 withdrawals.

10. Splits or Zora rewards not withdrawn

    0xSplits, Zora

    $1 · 1 position

    Money was sent to you through 0xSplits, or you earned Zora creator or referral rewards, and it is still inside the contract waiting for you to withdraw.

    1. Splits: open SplitMain 0x2ed6c4B5dA6378c7897AC67Ba9e43102Feb694EE on Etherscan and call withdraw(account, withdrawETH, tokens[]) with your address. Anyone can call it.

    3. The Splits app (app.splits.org) can also help.

12. Hyphen bridge funds stuck

    Biconomy Hyphen

    <$1 · 1 position

    Hyphen (Biconomy) is no longer supported. Liquidity provider positions may still be withdrawn from the contracts. Transfers that never arrived need the Biconomy team. We could not confirm this from official docs.

    1. If you provided liquidity, call removeLiquidity with your NFT id on the chain's LiquidityProviders contract on Etherscan (Write tab).
    2. For a farming NFT, first call withdraw(nftId, to) on the LiquidityFarming contract.
    3. If you sent a transfer that never arrived, contact Biconomy; only their executors can release it.
