   $345 · 1 position

   You withdrew from a Symbiotic vault and the epoch has ended, but you never claimed the tokens. They wait in the vault for the claimer address.

   1. Open the Symbiotic app and connect the claimer wallet.
   2. Find the vault with a claimable withdrawal and press Claim.
   3. Confirm and pay gas in ETH.

2. dYdX v3 balance

   $52 · 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 Your USDC can still be taken out through the escape hatch, or withdrawn if already released.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.

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

   $50 · 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. Funds on shut-down Swellchain

   Swellchain, Swell

   $32 · 2 positions

   Swell closed Swellchain: the final withdrawal deadline was 2026-06-15 and the chain was to run until 2026-06-30. Withdrawals started before 15 June can still be finalized on Ethereum.

   1. If your withdrawal was started before 15 June: after the 7-day proof wait, prove it on the Ethereum OptimismPortal2 0x758E0EE66102816F5C3Ec9ECc1188860fbb87812 (proveWithdrawalTransaction).
   2. Then call finalizeWithdrawalTransaction on the same contract. You pay ETH gas.
   3. If you never started one: Swell said contract withdrawals were possible until 30 June but are technical. Ask Swell support.

5. Balancer v2 pool share

   $23 · 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.

6. K2 (Karak) chain balance

   $2 · 1 positionNeeds the team

   The K2 team's bridge on Ethereum now pays balances by Merkle proof (a list that proves your balance). The merkle root is set and claims are not paused. After 2027-09-12 the guardian can sweep what is left.

   1. Ask the K2 team for your Merkle proof. We could not find an official page that gives proofs.
   2. On the OptimismPortal 0xeeCE9CD7Abd1CC84d9dfc7493e7e68079E47eA73 call claimETH(_amount, _proof) for ETH.
   3. For tokens, call claimTokens(_tokens, _amounts, _proof) on the L1StandardBridge 0xBA61F25dd9f2d5f02D01B1C2c1c5F0B14c4B48A3.

7. Expired Element Finance position

   <$1 · 1 position

   You hold Element v1 principal tokens (PT), yield tokens (YT) or pool shares. All tranches have ended, so they can be redeemed.

   1. Open the tranche contract (tranche_or_pool column) on Etherscan, Write Contract tab.
   2. PT: call withdrawPrincipal(amount, to). YT: call withdrawInterest(amount, to). Both only work after the tranche expiry.
   3. LP shares: exit the Balancer pool with exitPool first, then redeem as above.
