1. Unclaimed OP Mainnet or Base withdrawal

   Optimism, Base

   $23 · 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. Nucleus vault shares

   Nucleus (BoringVault)

   $3 · 2 positions

   Nucleus deprecated its vaults on 19 Dec 2025 and the withdraw page is gone. You can redeem vault shares through the Teller contract, but only for assets the vault still holds.

   1. Read the Nucleus deprecation guide first.
   2. Check which tokens the vault still holds, and your vault token balance, on Etherscan (or the Plume explorer).
   3. On the vault's Teller contract, Write tab, call bulkWithdraw(withdrawAsset, shareAmount, minimumAssets, to). The guide says to use 0 for minimumAssets.

3. Nile (legacy, Linea) LP tokens

   $2 · 1 position

   Nile (legacy, Linea) is a closed exchange. Your liquidity-pool (LP) tokens still give a share of the tokens in the pair contract. The website is gone, so you use the contracts directly.

   1. Find the pair contract in the 'pair' column of your row. If your LP tokens are staked in a farm, withdraw them there first.
   2. Approve the LP tokens to this exchange's old router contract, then call removeLiquidity on it in the explorer's Write tab.
   3. Never send LP tokens to the pair by hand: anyone can call burn first and take them. If no router works, ask a developer.
