1. Old Maker SCD vault collateral

   $15 · 1 position

   You own an old single-collateral Dai vault (CDP) that still has collateral (PETH) left after the system was shut down.

   1. Open the Tub contract 0x448a5065aeBB8E423F0896E6c5D525C040f59af3 on Etherscan, Write tab.
   2. If the vault still has debt, anyone can call bite(cupId) first. Then the vault owner calls free(cup, ink) to get PETH.
   3. Call exit(wad) to swap PETH for WETH. If a DSProxy owns the vault, send these calls through the proxy.

2. Archived L2 bridge funds

   Archived L2s

   $15 · 1 positionMay not work

   This chain shut down and its state is gone, so no one can prove a withdrawal now. The Ethereum bridge still holds the money; only the chain team can release it.

   1. Use the official bridge of the chain you withdrew from (linked next to each of your positions).
   2. Check that chain's official site for a refund or recovery notice.
   3. Without the chain's final state nobody can prove a withdrawal. Only the chain team can release the bridge funds.

3. PoolTogether deposit still in pool

   $11 · 1 position

   You deposited into a PoolTogether v3 or v4 prize pool and never withdrew. Your deposit is still in the pool contract.

   1. Open the prize pool contract (prize_pool address) on the block explorer.
   2. v4: call withdrawFrom(from, amount) with your address. v3: call withdrawInstantlyFrom(from, amount, controlledToken, maximumExitFee).
   3. v3 can charge an early-exit fee. Confirm and check your wallet.

4. Old SAI stablecoin to cash out

   Maker SAI

   $1 · 1 position

   SAI (the first Dai) was shut down. Each SAI can still be cashed for a fixed amount of WETH: 0.0052856 WETH per SAI (read from the contract).

   1. Approve first: on the SAI token 0x89d24A6b4CcB1B6fAA2625fE562bDD9a23260359 call approve(spender = 0xBda109309f9FafA6Dd6A9CB9f1Df4085B27Ee8eF, amount).
   2. Open the SaiTap contract 0xBda109309f9FafA6Dd6A9CB9f1Df4085B27Ee8eF on Etherscan, Write tab, and connect your wallet.
   3. Call cash(wad) with your SAI amount. You receive WETH.

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

   <$1 · 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.
