1. Unclaimed Arbitrum withdrawal

   Arbitrum One, Arbitrum Nova

   $10,608 · 1 position

   You withdrew ETH or tokens from Arbitrum to Ethereum but never did the final claim on Ethereum. The challenge period (about 6.4 days) is long over, so the funds can be claimed now.

   1. Open the Arbitrum bridge and connect the receiving wallet.
   2. Open Transactions and find the withdrawal marked Claim, or paste the withdrawal transaction hash.
   3. Press Claim and confirm. You pay the Ethereum gas fee. The funds go to the recipient.

2. Unclaimed OP Mainnet or Base withdrawal

   Optimism, Base

   $4,605 · 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.

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

   $1,551 · 3 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. Balancer v1 or CoW AMM pool share

   $84 · 1 position

   You hold tokens of an old Balancer v1 pool or a Balancer CoW AMM pool. There is no Balancer app for v1, but you can leave the pool through the contract.

   1. Open the pool address (pool column) on the block explorer, Write Contract tab.
   2. Call exitPool(poolAmountIn, minAmountsOut) with your pool token amount. Use zeros for the minimums only if you accept any price.
   3. If your tokens are staked elsewhere, withdraw them there first. Balancer also publishes an open-source exit tool: github.com/balancer/exit-ui (no hosted copy was online on 2026-10-01).

5. Expired veBAL lock

   Balancer

   $75 · 1 position

   Your veBAL lock ended but you never withdrew. You get 80BAL-20WETH pool tokens back, not BAL.

   1. Open the veBAL contract on Etherscan and go to Write Contract.
   2. Connect the owner wallet and call withdraw().
   3. Then exit the Balancer 80/20 pool to get BAL and WETH.

6. Balancer v2 pool share

   $74 · 1 position

   You hold Balancer v2 pool tokens, in your wallet or staked. You can exit the pool. Balancer has proposed a wind-down: if it passes, pools become withdraw-only on 30 Oct 2026.

   1. Open the Balancer app, find your pool and use Remove liquidity. Do this before 30 Oct 2026.
   2. If the app does not work, call exitPool on the Balancer v2 Vault 0xBA12222222228d8Ba445958a75a0704d566BF2C8 (Etherscan, Write tab).
   3. If your tokens are staked in Aura, Beefy or a gauge, unstake there first.

7. KNCL never swapped to KNC

   Kyber (KNCL)

   $55 · 1 position

   You hold old KNCL tokens that were never swapped to KNC. The KNC token contract still accepts them.

   1. Approve first: on the old KNC token (KNCL) 0xdd974D5C2e2928deA5F71b9825b8b646686BD200 call approve(spender = 0xdeFA4e8a7bcBA345F687a2f1456F5Edd9CE97202, amount).
   2. Open the KNC contract 0xdeFA4e8a7bcBA345F687a2f1456F5Edd9CE97202 on Etherscan, Write as Proxy tab, and connect your wallet.
   3. Call mintWithOldKnc(amount). It burns your KNCL and mints KNC 1 to 1.

8. REPv1 never swapped to REPv2

   Augur (REP)

   $1 · 1 position

   You hold old REPv1 tokens that were never swapped to REPv2. The REPv2 contract still accepts them.

   1. Approve first: on REPv1 0x1985365e9f78359a9B6AD760e32412f4a445E862 call approve(spender = 0x221657776846890989a759BA2973e427DfF5C9bB, your full REPv1 balance).
   2. Open the REPv2 contract 0x221657776846890989a759BA2973e427DfF5C9bB on Etherscan, Write tab, and connect your wallet.
   3. Call migrateFromLegacyReputationToken(). It moves your whole REPv1 balance and mints REPv2 1 to 1.

9. dYdX v3 balance

   <$1 · 1 position

   dYdX v3 was shut down and its exchange was set to 'frozen' on Ethereum. Your USDC can still be taken out through the escape hatch, or withdrawn if already released.

   1. Open dYdX's v3 sunset post and use the Escape Hatch link in its last update. It is hosted by an independent third party.
   2. Escape needs a proof for your stark key and position. The page builds it; the escape call goes to StarkPerpetual 0xD54f502e184B6B739d7D27a6410a67dc462D69c8.
   3. Then call withdraw from your registered Ethereum address to receive the USDC. You pay Ethereum gas.
