How to get it back

3 guides, the largest amount first

Use only the official links below. No real recovery asks for your seed phrase or private key. If anyone offers to recover funds for you, it is a scam.

Unclaimed OP Mainnet or Base withdrawal
Optimism, Base
$134 · 1 position
You withdrew ETH or tokens from OP Mainnet or Base to Ethereum but never did the last step on Ethereum. The funds wait in the bridge contract.
1. OP Mainnet: open the Optimism bridge (app.optimism.io/bridge), connect the receiving wallet, open your withdrawal, press Prove, then Finalize after 7 days.
2. Base: Base's docs list Superbridge and Brid.gg as its bridges. Open one, connect the receiving wallet, find the withdrawal, press Prove, then Finalize.
3. Base waits 5 days after Prove (1 day if both a TEE proof and a ZK proof back it). Pay the Ethereum gas fee each time.

MKR never converted to SKY
Maker / Sky
$69 · 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.

Unclaimed Arbitrum withdrawal
Arbitrum One, Arbitrum Nova
$68 · 2 positions
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.
