How to get it back

5 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.

dYdX v3 balance
$267 · 1 position
dYdX v3 was shut down and its exchange was set to 'frozen' on Ethereum. Your USDC can still be taken out through the escape hatch, or withdrawn if already released.
1. Open dYdX's v3 sunset post and use the Escape Hatch link in its last update. It is hosted by an independent third party.
2. Escape needs a proof for your stark key and position. The page builds it; the escape call goes to StarkPerpetual 0xD54f502e184B6B739d7D27a6410a67dc462D69c8.
3. Then call withdraw from your registered Ethereum address to receive the USDC. You pay Ethereum gas.

K2 (Karak) chain balance
$13 · 1 positionNeeds the team
The K2 team's bridge on Ethereum now pays balances by Merkle proof (a list that proves your balance). The merkle root is set and claims are not paused. After 2027-09-12 the guardian can sweep what is left.
1. Ask the K2 team for your Merkle proof. We could not find an official page that gives proofs.
2. On the OptimismPortal 0xeeCE9CD7Abd1CC84d9dfc7493e7e68079E47eA73 call claimETH(_amount, _proof) for ETH.
3. For tokens, call claimTokens(_tokens, _amounts, _proof) on the L1StandardBridge 0xBA61F25dd9f2d5f02D01B1C2c1c5F0B14c4B48A3.

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.

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.

MATIC never swapped to POL
Polygon
$2 · 1 position
You hold old MATIC on Ethereum that was never swapped to POL. The swap is 1 to 1. Polygon has not announced a deadline.
1. Open the Polygon Portal upgrade page and connect your wallet. Switch the wallet to Ethereum.
2. Approve the upgrade contract to use your MATIC.
3. Confirm the migrate transaction to receive POL. You pay Ethereum gas.
