2. K2 (Karak) chain balance

   $3 · 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.

5. Nucleus vault shares

   Nucleus (BoringVault)

   $1 · 1 position

   Nucleus deprecated its vaults on 19 Dec 2025 and the withdraw page is gone. You can redeem vault shares through the Teller contract, but only for assets the vault still holds.

   1. Read the Nucleus deprecation guide first.
   2. Check which tokens the vault still holds, and your vault token balance, on Etherscan (or the Plume explorer).
   3. On the vault's Teller contract, Write tab, call bulkWithdraw(withdrawAsset, shareAmount, minimumAssets, to). The guide says to use 0 for minimumAssets.

   1. Open the position contract 0x434575EaEa081b735C985FA9bf63CD7b87e227F9 on Blastscan, Write tab, and connect the wallet that owns the NFT.
   2. Call decreaseLiquidity with your tokenId, the liquidity amount, amount0Min, amount1Min and a deadline. Thruster's old guide explains each field.
   3. Then call collect(tokenId, recipient, max, max) to receive the tokens. You can call burn(tokenId) afterwards to delete the empty NFT.
   4. If the NFT is not in your wallet, it may be locked in another contract such as Hyperlock. Withdraw it from there first.

7. zkSync Lite balance not claimed

   <$1 · 3 positions

   zkSync Lite was shut down on 2026-05-04. Remaining balances are claimable on Ethereum through a claim contract and a withdrawal portal. Your account is on that list and has not claimed.

   1. Open the zkSync Lite withdrawal portal and connect the wallet that owned the account.
   2. The portal finds your address in the final state, builds the proof and sends the claim. Follow its prompts.
   3. Confirm the Ethereum transaction. Tokens go to your L1 address. Matter Labs sponsors gas for the first 100,000 withdrawals.
