1. Unclaimed OP Mainnet or Base withdrawal

   Optimism, Base

   $130 · 37 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.

2. USDC burned but not minted

   Circle CCTP

   $12 · 11 positions

   USDC was burned on one chain through Circle CCTP but the matching USDC was never minted on the destination chain. Circle can still sign it, so it can be completed.

   1. Find the burn transaction hash on the source chain.
   2. Get the signed attestation for it from Circle's attestation API (see the Circle CCTP docs).
   3. On the destination chain, call receiveMessage(message, attestation) on the MessageTransmitter contract. You pay the gas fee. USDC goes to the recipient.

3. Old Polygon Plasma bridge exit

   $6 · 3 positions

   You withdrew from Polygon through the old Plasma bridge and the exit was never finished on Ethereum. Polygon's current docs no longer describe this bridge, so the route is not confirmed.

   1. Open Polygon Portal, connect the wallet that burned the tokens, and check Transactions for your exit.
   2. If Portal shows Initiate Claim or Claim Tokens, follow it and pay the Ethereum gas fee.
   3. If it is not listed, the exit must be run on the Polygon contracts directly. Ask Polygon support, with the burn transaction hash.

7. STG never swapped to ZRO
