1. USDC burned but not minted

   Circle CCTP

   $131 · 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. Unclaimed OP Mainnet or Base withdrawal

   Optimism, Base

   $76 · 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.

3. Expired veCRV lock

   Curve

   $39 · 1 position

   2. Connect the owner wallet and call withdraw().

6. Curve fees not claimed (3CRV)

   $6 · 1 position

   You locked CRV in veCRV and earned fee rewards in 3CRV from the old Curve fee distributor, but never claimed them. They are still in the contract.

   1. Open the contract's Write tab on the block explorer and connect your wallet.
   2. Call claim with your address. Anyone can call it; the tokens go to you.
   3. If many weeks are unclaimed, repeat the call; each call covers up to 20 weeks.
   4. Check your wallet for the 3CRV.

7. zkSync Lite balance not claimed

   $4 · 4 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.
