1. Unclaimed OP Mainnet or Base withdrawal

   Optimism, Base

   $2,682 · 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. Curve fees not claimed (3CRV)

   $56 · 1 position

   You locked CRV in veCRV and earned fee rewards in 3CRV from the old Curve fee distributor, but never claimed them. They are still in the contract.

   1. Open the contract's Write tab on the block explorer and connect your wallet.
   2. Call claim with your address. Anyone can call it; the tokens go to you.
   3. If many weeks are unclaimed, repeat the call; each call covers up to 20 weeks.
   4. Check your wallet for the 3CRV.

3. Funds in old Ethereum contracts (2015-2021)

   $6 · 2 positions

   You have a balance in an old Ethereum contract (The DAO, EtherDelta, IDEX, the 2017 ENS registrar, DigixDAO and others). Each contract has its own withdraw call. Use the wallet that owns the position.

   1. The DAO: on the DAO token 0xbb9bc244d798123fde783fcc1c72d3bb8c189413 call approve(0xbf4ed7b27f1d666546e30d74d50d173d20bca754, yourBalance). Then call withdraw() on the WithdrawDAO contract 0xbf4ed7b27f1d666546e30d74d50d173d20bca754. It pays 1 ETH per 100 DAO.
   2. EtherDelta 0x8d12a197cb00d4747a1fe03395095ce2a5cc6819: from the wallet that deposited, call withdraw(amount) for ETH or withdrawToken(token, amount) for a token. Amounts are in the token's smallest unit.
   3. IDEX v1 0x2a0c0dbecc7e4d658f48e01e3fa353f44050c208: call withdraw(token, amount). Use token 0x0000000000000000000000000000000000000000 for ETH. It reverts if your last IDEX activity was fewer than 240 blocks ago.
   4. 2017 ENS registrar 0x6090a6e47849629b7245dfa1ca21d94cd15878ef: call releaseDeed(labelhash) for the name. The labelhash is keccak256 of the name without .eth. The deposit goes back to the deed owner.
   5. Other contracts (DigixDAO, Neufund and more): use the contract's own withdraw or refund function on Etherscan from the owner wallet. Check the contract's code first.

4. Prisma Finance leftover funds

   $2 · 1 position

   Prisma was exploited in 2024 and wound down. You may have collateral left over after a redemption, Stability Pool gains or deposits, or other claimable funds. They are still in the contracts.

   1. Read the wind-down guide linked below to see which pot your row is in.
   2. Leftover collateral: on the Trove Manager contract in your row, Write tab, call claimCollateral(receiver) from your wallet.
   3. Stability Pool 0xed8b26d99834540c5013701bb3715fafd39993ba: call withdrawFromSP(0), then claimCollateralGains(recipient, collateralIndexes). Deposits: withdrawFromSP(amount).
