1. Nucleus vault shares

   Nucleus (BoringVault)

   $25 · 3 positions

   Nucleus deprecated its vaults on 19 Dec 2025 and the withdraw page is gone. You can redeem vault shares through the Teller contract, but only for assets the vault still holds.

   1. Read the Nucleus deprecation guide first.
   2. Check which tokens the vault still holds, and your vault token balance, on Etherscan (or the Plume explorer).
   3. On the vault's Teller contract, Write tab, call bulkWithdraw(withdrawAsset, shareAmount, minimumAssets, to). The guide says to use 0 for minimumAssets.

2. Archived L2 bridge funds

   Archived L2s

   $4 · 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.

3. USDC burned but not minted

   Circle CCTP

   $1 · 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. Polygon zkEVM balance

   <$1 · 5 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.

5. 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.

6. Unclaimed OP Stack chain withdrawal

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

   <$1 · 1 position

   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.
