1. K2 (Karak) chain balance

   $268 · 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.

2. Archived L2 bridge funds

   Archived L2s

   $33 · 2 positionsMay 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. Lisk L2 balance (closing)

   $1 · 1 position

   Lisk's own chain closes on 2026-10-31. Lisk says withdrawing to Ethereum takes about 8 days, and unstaking LSK adds 3 days. Start now.

   1. Open the Lisk bridge (type bridge.lisk.com yourself) and connect your wallet.
   2. Withdraw your assets to Ethereum. If you staked LSK, unlock it first and wait 3 days.
   3. After the wait, prove and finalize the withdrawal on Ethereum. You pay gas on both chains.

12. Hyphen bridge funds stuck

    Biconomy Hyphen

    <$1 · 2 positions

    Hyphen (Biconomy) is no longer supported. Liquidity provider positions may still be withdrawn from the contracts. Transfers that never arrived need the Biconomy team. We could not confirm this from official docs.

    1. If you provided liquidity, call removeLiquidity with your NFT id on the chain's LiquidityProviders contract on Etherscan (Write tab).
    2. For a farming NFT, first call withdraw(nftId, to) on the LiquidityFarming contract.
    3. If you sent a transfer that never arrived, contact Biconomy; only their executors can release it.

13. Unclaimed OP Mainnet or Base withdrawal

    Optimism, Base

    $0 · 1 position

    You withdrew ETH or tokens from OP Mainnet or Base to Ethereum but never did the last step on Ethereum. The funds wait in the bridge contract.

    1. OP Mainnet: open the Optimism bridge (app.optimism.io/bridge), connect the receiving wallet, open your withdrawal, press Prove, then Finalize after 7 days.
    2. Base: Base's docs list Superbridge and Brid.gg as its bridges. Open one, connect the receiving wallet, find the withdrawal, press Prove, then Finalize.
    3. Base waits 5 days after Prove (1 day if both a TEE proof and a ZK proof back it). Pay the Ethereum gas fee each time.
