1. NEAR Rainbow Bridge withdrawal

   $115 · 2 positionsNeeds the team

   You moved an ERC-20 from NEAR to Ethereum and the tokens were burned on NEAR but never unlocked on Ethereum. The Ethereum light client stopped in April 2025, so claiming may not work.

   1. Open Rainbow Bridge and check if your withdrawal can still be finished.
   2. If it asks for a proof, the Ethereum light client is paused, so the step may fail.
   3. Ask the NEAR or Aurora team about the Omni Bridge for stuck Rainbow transfers.

2. Funds on Silicon L2

   $3 · 1 position

   Silicon is closing. Its bridge deposits stopped on 2026-09-02. You can withdraw to Ethereum until 2026-12-31 12:00 (UTC+9). Silicon says unwithdrawn assets cannot be recovered after that.

   1. Do this before 2026-12-31. Connect a WalletConnect wallet such as MetaMask to the Silicon bridge.
   2. Choose Withdraw, pick the asset and amount, check the destination address, and confirm.
   3. In the Activity screen wait 10 to 30 minutes, then click Finalize. You pay ETH gas.
   4. Tokens issued inside Silicon cannot be bridged. Korbit Web3 Wallet users must follow the Korbit guide.

3. RNDR never swapped to RENDER

   <$1 · 1 positionMay not work

   You hold old RNDR on Ethereum that was never upgraded. The Render upgrade portal swaps it 1 to 1 for RENDER on Solana. The swap is one-way.

   1. Open the Render upgrade portal. You need an Ethereum wallet with RNDR and a Solana wallet.
   2. Connect both wallets.
   3. Approve RNDR and confirm the upgrade. You pay Ethereum gas.

   <$1 · 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.

5. 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.

6. Unclaimed Arbitrum withdrawal

   Arbitrum One, Arbitrum Nova

   $0 · 1 position

   You withdrew ETH or tokens from Arbitrum to Ethereum but never did the final claim on Ethereum. The challenge period (about 6.4 days) is long over, so the funds can be claimed now.

   1. Open the Arbitrum bridge and connect the receiving wallet.
   2. Open Transactions and find the withdrawal marked Claim, or paste the withdrawal transaction hash.
   3. Press Claim and confirm. You pay the Ethereum gas fee. The funds go to the recipient.

7. Unclaimed Polygon PoS withdrawal

   Polygon PoS bridge

   $0 · 1 position

   You burned tokens on Polygon to withdraw to Ethereum, and the checkpoint is done, but the exit was never run on Ethereum. The tokens wait in the bridge.

   1. Open Polygon Portal and connect the wallet that withdrew.
   2. Find the withdrawal in your transactions and press Initiate Claim.
   3. Approve in your wallet, then press Claim Tokens. Pay the Ethereum gas fee. The tokens go to the burner address.

8. Wormhole transfer not redeemed

   Wormhole Portal

   $0 · 4 positionsNeeds the team

   You sent tokens with Portal (Wormhole), but nobody completed the transfer on the destination chain. You can redeem it yourself with the signed VAA (the guardians' signed message).

   1. Find your transfer on Wormholescan with your source transaction hash.
   2. If it is not redeemed, open Portal Bridge, choose Redeem, and complete it with your wallet.
   3. Or copy the VAA from the Advanced tab on Wormholescan and submit it on the destination chain contract (Etherscan Write tab).

9. Archived L2 bridge funds

   Archived L2s

   $0 · 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.
