1. Archived L2 bridge funds

   Archived L2s

   $14 · 3 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.

2. Unclaimed OP Stack chain withdrawal

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

   $7 · 2 positionsMay not work$4You can claim$3

   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.

3. USDC burned but not minted

   Circle CCTP

   $5 · 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.

4. Unclaimed Orbit chain withdrawal

   Arbitrum Orbit chains (Robinhood, Plume, ApeChain and others)

   <$1 · 1 position

   You withdrew from an Arbitrum Orbit chain to its parent chain, but the last step (execute on the parent chain) was never done. The funds are held in the 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, or paste the withdrawal transaction hash.
   3. When the challenge period is over, press Claim. You pay the gas fee on the parent chain.

5. Hop transfer not received

   Hop Protocol

   <$1 · 1 position

   You sent a Hop transfer long ago and it was never paid out on the destination chain. The funds are still in Hop's bridge contract and its withdraw function still works, but Hop's website and data service are gone, so there is no ready tool: the withdrawal has to be built from on-chain data.

   1. hop.exchange and every address under it (app.hop.exchange, docs.hop.exchange) no longer belong to Hop: hop.exchange now shows a gambling site. Do not open them or connect a wallet there.
   2. Find your transfer in the TransferSent event of your transaction on the origin chain (block explorer, Logs tab). It holds the transfer ID, recipient, amount, transferNonce, bonderFee and the swap values.
   3. The withdraw function also needs a Merkle proof of your transfer. Hop's open-source node tool has a withdrawal-proof command for it, but the tool reads Hop's data service at subgraph.hop.exchange, which no longer answers, so a developer has to point it at another source or rebuild the proof from on-chain events.
   4. With the proof, call withdraw on the Hop bridge contract of the destination chain (block explorer, Write tab) from the wallet that should receive the funds. You pay gas.
   5. On a Layer 2 destination you receive hTokens (for example hUSDC). They can be swapped to the native token in Hop's AMM on that chain.

6. Unclaimed OP Mainnet or Base withdrawal

   Optimism, Base

   <$1 · 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.

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. Polygon zkEVM balance

   <$1 · 2 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.

9. 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.
