How to get it back

4 guides, the largest amount first

Use only the official links below. No real recovery asks for your seed phrase or private key. If anyone offers to recover funds for you, it is a scam.

USDC burned but not minted
Circle CCTP
$16 · 2 positions
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.

zkSync Lite balance not claimed
$3 · 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.

Unclaimed OP Mainnet or Base withdrawal
Optimism, Base
$2 · 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.

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.
