How to get it back

Old Mantle v1 withdrawal
$77 · 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.

Polygon zkEVM balance
$46 · 2 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.

Funds on shut-down Swellchain
Swellchain, Swell
$26 · 1 position
Swell closed Swellchain: the final withdrawal deadline was 2026-06-15 and the chain was to run until 2026-06-30. Withdrawals started before 15 June can still be finalized on Ethereum.
1. If your withdrawal was started before 15 June: after the 7-day proof wait, prove it on the Ethereum OptimismPortal2 0x758E0EE66102816F5C3Ec9ECc1188860fbb87812 (proveWithdrawalTransaction).
2. Then call finalizeWithdrawalTransaction on the same contract. You pay ETH gas.
3. If you never started one: Swell said contract withdrawals were possible until 30 June but are technical. Ask Swell support.
