   3. Approve in your wallet, then press Claim Tokens. Pay the Ethereum gas fee. The tokens go to the burner address.

3. K2 (Karak) chain balance

   $1 · 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.
