1. Unclaimed OP Mainnet or Base withdrawal

   Optimism, Base

   $3 · 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. Lisk L2 balance (closing)

   <$1 · 2 positions

   Lisk's own chain closes on 2026-10-31. Lisk says withdrawing to Ethereum takes about 8 days, and unstaking LSK adds 3 days. Start now.

   1. Open the Lisk bridge (type bridge.lisk.com yourself) and connect your wallet.
   2. Withdraw your assets to Ethereum. If you staked LSK, unlock it first and wait 3 days.
   3. After the wait, prove and finalize the withdrawal on Ethereum. You pay gas on both chains.

3. Funds on shut-down Swellchain

   Swellchain, Swell

   <$1 · 1 position

   Swell closed Swellchain: the final withdrawal deadline was 2026-06-15 and the chain was to run until 2026-06-30. Withdrawals started before 15 June can still be finalized on Ethereum.

   1. If your withdrawal was started before 15 June: after the 7-day proof wait, prove it on the Ethereum OptimismPortal2 0x758E0EE66102816F5C3Ec9ECc1188860fbb87812 (proveWithdrawalTransaction).
   2. Then call finalizeWithdrawalTransaction on the same contract. You pay ETH gas.
   3. If you never started one: Swell said contract withdrawals were possible until 30 June but are technical. Ask Swell support.

4. Polygon zkEVM balance

   <$1 · 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.

5. Archived L2 bridge funds

   Archived L2s

   <$1 · 1 positionMay 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.

6. 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.

7. Ended Sablier stream (no price)

   $0 · 1 position

   An ended or canceled Sablier stream whose token has no known price. Most are airdrop vesting or spam tokens, so the value is unknown and may be zero.

   1. Open the Sablier app and connect the wallet that owns the stream.
   2. Press Withdraw on the ended stream if you want the tokens.
   3. Be careful with unknown tokens: many are spam.
