1. Old Mantle v1 withdrawal

   $3 · 1 position

   You withdrew from the old Mantle chain (2023 to March 2024) and the withdrawal never finished on Ethereum. We could not confirm that the current Mantle bridge still finishes pre-upgrade withdrawals.

   1. Open the Mantle bridge and connect the wallet that made the withdrawal.
   2. Find the withdrawal in your history. Current withdrawals need Prove (about 30 minutes), then Claim on Ethereum about 30 minutes later.
   3. If an old withdrawal is not listed, contact Mantle support with the transaction hash.

2. Nucleus vault shares

   Nucleus (BoringVault)

   $2 · 1 position

   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.

3. friend.tech keys still held

   <$1 · 1 position

   You hold friend.tech keys on Base. The contract still lets you sell them back for ETH, even if the app does not work.

   1. Open the contract's Write tab on Basescan, connect your wallet, and call sellShares(sharesSubject, amount) from the holder wallet.
   2. Use the key owner's address as sharesSubject. The last key of a subject can never be sold.
   3. The ETH arrives in your wallet, minus the sell fees.

4. 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.
