1. Unclaimed OP Mainnet or Base withdrawal

   Optimism, Base

   $27 · 1 position

   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. Old Mantle v1 withdrawal

   $11 · 1 position

   You withdrew from the old Mantle chain (2023 to March 2024) and the withdrawal never finished on Ethereum. We could not confirm that the current Mantle bridge still finishes pre-upgrade withdrawals.

   1. Open the Mantle bridge and connect the wallet that made the withdrawal.
   2. Find the withdrawal in your history. Current withdrawals need Prove (about 30 minutes), then Claim on Ethereum about 30 minutes later.
   3. If an old withdrawal is not listed, contact Mantle support with the transaction hash.

3. Harmony balance (chain halted)

   $8 · 1 positionNeeds the team

   Harmony proposed (non-binding, 7 Sept 2026) a final snapshot and an ERC-20 ONE airdrop on Ethereum. This list shows positions at the last block our data saw. You cannot sign anything on the chain now.

   1. Do not expect to withdraw this yourself. The chain is halted.
   2. Watch Harmony's official channels for the vote result and the snapshot rules.
   3. Keep access to your wallet. The proposal says the airdrop would go to the same address on Ethereum.

4. Unclaimed OP Stack chain withdrawal

   Blast, Mantle, Mode, Zora, Lisk, Ink, Unichain and other OP chains

   <$1 · 1 position

   You withdrew from an OP Stack chain to Ethereum but never completed the last step. The funds wait in that chain's bridge.

   1. Use the official bridge of the chain you withdrew from (linked next to each of your positions).
   2. Connect the receiving wallet and open your transactions. Press Prove, wait out the challenge period shown on the page, then press Finalize.
   3. Pay the Ethereum gas fee each time.

5. Balancer v2 pool share

   <$1 · 1 position

   You hold Balancer v2 pool tokens, in your wallet or staked. You can exit the pool. Balancer has proposed a wind-down: if it passes, pools become withdraw-only on 30 Oct 2026.

   1. Open the Balancer app, find your pool and use Remove liquidity. Do this before 30 Oct 2026.
   2. If the app does not work, call exitPool on the Balancer v2 Vault 0xBA12222222228d8Ba445958a75a0704d566BF2C8 (Etherscan, Write tab).
   3. If your tokens are staked in Aura, Beefy or a gauge, unstake there first.

6. Polygon zkEVM balance

   <$1 · 3 positions

   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.

7. zkSync Lite balance not claimed

   <$1 · 1 position

   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.

8. Wormhole transfer not redeemed

   Wormhole Portal

   $0 · 1 positionNeeds the team

   1. Find your transfer on Wormholescan with your source transaction hash.
   2. If it is not redeemed, open Portal Bridge, choose Redeem, and complete it with your wallet.
   3. Or copy the VAA from the Advanced tab on Wormholescan and submit it on the destination chain contract (Etherscan Write tab).
