zkSync Lite balance not claimed
$1,296 · 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.
