Unclaimed Polygon PoS withdrawal
Polygon PoS bridge
$905 · 1 position
You burned tokens on Polygon to withdraw to Ethereum, and the checkpoint is done, but the exit was never run on Ethereum. The tokens wait in the bridge.

2. Find the withdrawal in your transactions and press Initiate Claim.
3. Approve in your wallet, then press Claim Tokens. Pay the Ethereum gas fee. The tokens go to the burner address.

Unclaimed Arbitrum withdrawal
Arbitrum One, Arbitrum Nova
$761 · 1 position
You withdrew ETH or tokens from Arbitrum to Ethereum but never did the final claim on Ethereum. The challenge period (about 6.4 days) is long over, so the funds can be claimed now.
1. Open the Arbitrum bridge and connect the receiving wallet.
2. Open Transactions and find the withdrawal marked Claim, or paste the withdrawal transaction hash.
3. Press Claim and confirm. You pay the Ethereum gas fee. The funds go to the recipient.

zkSync Lite balance not claimed
$328 · 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.

MKR never converted to SKY
Maker / Sky
$3 · 1 position
You hold MKR, or MKR in the old DSChief voting contract, that was never converted to SKY. The converter still works. Its fee is 5% now (read on-chain 2026-10-01) and rises 1 point every 3 months.
1. Open the Sky app and connect your wallet.
2. If your MKR is in the old DSChief voting contract, first call free(amount) on that contract.
3. Approve MKR, then convert it to SKY. You get 24,000 SKY per MKR minus the fee.
4. Without the app: call mkrToSky(usr, mkrAmt) on the converter 0xA1Ea1bA18E88C381C724a75F23a130420C403f9a.

2. Approve the upgrade contract to use your MATIC.
3. Confirm the migrate transaction to receive POL. You pay Ethereum gas.
