1. Archived L2 bridge funds

   Archived L2s

   $416 · 3 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.

2. Unclaimed Orbit chain withdrawal

   Arbitrum Orbit chains (Robinhood, Plume, ApeChain and others)

   $41 · 8 positions

   You withdrew from an Arbitrum Orbit chain to its parent chain, but the last step (execute on the parent chain) was never done. The funds are held in the 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, or paste the withdrawal transaction hash.
   3. When the challenge period is over, press Claim. You pay the gas fee on the parent chain.

3. K2 (Karak) chain balance

   $26 · 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.
