1. Unclaimed OP Mainnet or Base withdrawal

   Optimism, Base

   $24 · 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.

2. Funds in frozen StarkEx apps

   Sorare, Immutable X, ApeX Pro, edgeX v1, Myria

   $8 · 2 positionsYou can claim$7May not work$1

   Some StarkEx apps keep balances off-chain. A pending withdrawal can be claimed now. A deposit-only record cannot: the app operator must first publish data.

   1. Check the row type. A pending withdrawal can be claimed now; a deposit ledger row cannot.
   2. For a pending withdrawal, call withdraw with your owner key and asset type on the app's StarkEx contract (Etherscan). Funds go to your registered address.
   3. For a frozen app, the escape hatch needs the operator or data committee to publish state first. See the StarkWare docs.

3. Archived L2 bridge funds

   Archived L2s

   $5 · 1 positionMay not work

   This chain shut down and its state is gone, so no one can prove a withdrawal now. The Ethereum bridge still holds the money; only the chain team can release it.

   1. Use the official bridge of the chain you withdrew from (linked next to each of your positions).
   2. Check that chain's official site for a refund or recovery notice.
   3. Without the chain's final state nobody can prove a withdrawal. Only the chain team can release the bridge funds.

4. zkSync Lite balance not claimed

   $2 · 1 position

   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.

5. Thruster v3 position on Blast

   $2 · 1 position

   You hold a Thruster v3 liquidity position (an NFT) on Blast. Thruster has shut down, but the position contract still works.

   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.

6. Polygon zkEVM balance

   <$1 · 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.
