K2 (Karak) chain balance
$267 · 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.

zkSync Lite balance not claimed
$245 · 2 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.

Polygon zkEVM balance
$52 · 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.

Harmony balance (chain halted)
$50 · 1 positionNeeds the team
Harmony proposed (non-binding, 7 Sept 2026) a final snapshot and an ERC-20 ONE airdrop on Ethereum. This list shows positions at the last block our data saw. You cannot sign anything on the chain now.
1. Do not expect to withdraw this yourself. The chain is halted.
2. Watch Harmony's official channels for the vote result and the snapshot rules.
3. Keep access to your wallet. The proposal says the airdrop would go to the same address on Ethereum.
Seamless v1 deposit on Base
$11 · 1 position
You supplied funds to the Seamless v1 lending pool on Base (an Aave v3 fork). seamlessprotocol.com now redirects to X, but the pool contract still lets you withdraw.
1. Open the pool contract 0x8F44Fd754285aa6A2b8B9B97739B79746e0475a7 on Basescan, Write tab, connect wallet.
2. Call withdraw(asset, amount, to) with the token address, amount = max (type(uint256).max) and your wallet.
3. If you have debt, repay() first or withdraw only the free part.
