1. USDC burned but not minted

   Circle CCTP

   $35 · 1 position

   USDC was burned on one chain through Circle CCTP but the matching USDC was never minted on the destination chain. Circle can still sign it, so it can be completed.

   1. Find the burn transaction hash on the source chain.
   2. Get the signed attestation for it from Circle's attestation API (see the Circle CCTP docs).
   3. On the destination chain, call receiveMessage(message, attestation) on the MessageTransmitter contract. You pay the gas fee. USDC goes to the recipient.

2. Lisk L2 balance (closing)

   $3 · 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.

4. Archived L2 bridge funds

   Archived L2s

   $2 · 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.

5. Funds on shut-down Swellchain

   Swellchain, Swell

   $2 · 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.

6. Unclaimed OP Mainnet or Base withdrawal

   Optimism, Base

   <$1 · 4 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.
