1. Lighter withdrawal not collected

   $1,226 · 1 position

   You withdrew from Lighter and the money reached the Ethereum contract, but you never collected it. It waits in the contract for you.

   1. Open the Lighter app and go to withdraw history.
   2. Press the claim button on the pending withdrawal. Or use the Write tab of the ZkLighter contract 0x3B4D794a66304F130a4Db8F2551B0070dfCf5ca7 on Etherscan and call withdrawPendingBalance.
   3. Confirm and pay the Ethereum gas fee. Funds go to the owner address.

2. Hop transfer not received

   Hop Protocol

   <$1 · 1 position

   You sent a Hop transfer long ago and it was never paid out on the destination chain. The funds are still in Hop's bridge contract and its withdraw function still works, but Hop's website and data service are gone, so there is no ready tool: the withdrawal has to be built from on-chain data.

   1. hop.exchange and every address under it (app.hop.exchange, docs.hop.exchange) no longer belong to Hop: hop.exchange now shows a gambling site. Do not open them or connect a wallet there.
   2. Find your transfer in the TransferSent event of your transaction on the origin chain (block explorer, Logs tab). It holds the transfer ID, recipient, amount, transferNonce, bonderFee and the swap values.
   3. The withdraw function also needs a Merkle proof of your transfer. Hop's open-source node tool has a withdrawal-proof command for it, but the tool reads Hop's data service at subgraph.hop.exchange, which no longer answers, so a developer has to point it at another source or rebuild the proof from on-chain events.
   4. With the proof, call withdraw on the Hop bridge contract of the destination chain (block explorer, Write tab) from the wallet that should receive the funds. You pay gas.
   5. On a Layer 2 destination you receive hTokens (for example hUSDC). They can be swapped to the native token in Hop's AMM on that chain.

3. zkSync Lite balance not claimed

   <$1 · 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.

4. Old SAI stablecoin to cash out

   Maker SAI

   <$1 · 1 position

   SAI (the first Dai) was shut down. Each SAI can still be cashed for a fixed amount of WETH: 0.0052856 WETH per SAI (read from the contract).

   1. Approve first: on the SAI token 0x89d24A6b4CcB1B6fAA2625fE562bDD9a23260359 call approve(spender = 0xBda109309f9FafA6Dd6A9CB9f1Df4085B27Ee8eF, amount).
   2. Open the SaiTap contract 0xBda109309f9FafA6Dd6A9CB9f1Df4085B27Ee8eF on Etherscan, Write tab, and connect your wallet.
   3. Call cash(wad) with your SAI amount. You receive WETH.

5. Unclaimed OP Mainnet or Base withdrawal

   Optimism, Base

   $0 · 2 positions

   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.
