1. USDC burned but not minted

   Circle CCTP

   $36 · 3 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.

2. Polygon zkEVM balance

   $7 · 3 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.

3. zkSync Lite balance not claimed

   $5 · 5 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.

4. ReactorFusion deposit (zkSync)

   ReactorFusion (zkSync)

   $3 · 1 position

   ReactorFusion lending is shut down and the website is gone. Your deposit receipt token may still be redeemable, but only for the cash left in the market, after you repay any debt.

   1. Open the receipt token contract of your market (in your row) in the block explorer, Write tab, and connect your wallet.
   2. If you have an open loan, repay it first.
   3. Call redeem or redeemUnderlying (or withdraw, if the contract shows that name). You get at most the cash still in the market.
   4. Not tested by us. Pay the network fee in the chain's coin. A developer may be needed.

5. K2 (Karak) chain balance

   $2 · 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.

6. Balancer v2 pool share

   <$1 · 1 position

   You hold Balancer v2 pool tokens, in your wallet or staked. You can exit the pool. Balancer has proposed a wind-down: if it passes, pools become withdraw-only on 30 Oct 2026.

   1. Open the Balancer app, find your pool and use Remove liquidity. Do this before 30 Oct 2026.
   2. If the app does not work, call exitPool on the Balancer v2 Vault 0xBA12222222228d8Ba445958a75a0704d566BF2C8 (Etherscan, Write tab).
   3. If your tokens are staked in Aura, Beefy or a gauge, unstake there first.

7. Archived L2 bridge funds

   Archived L2s

   <$1 · 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.
