1. K2 (Karak) chain balance

   $7 · 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. Polygon zkEVM balance

   $3 · 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.

3. Ended Sablier stream not withdrawn

   <$1 · 1 position

   A Sablier payment stream to you has ended or was canceled, and the tokens in it were never withdrawn. The tokens are still in the Sablier contract.

   1. Open the Sablier app and connect the wallet that owns the stream.
   2. Find the ended stream and press Withdraw.
   3. The tokens go to the stream recipient. Pay the gas fee.

4. 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 Liquidity provider positions may still be withdrawn from the contracts.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.
