   Maker SAI

   1. Approve first: on the SAI token 0x89d24A6b4CcB1B6fAA2625fE562bDD9a23260359 call approve(spender = 0xBda109309f9FafA6Dd6A9CB9f1Df4085B27Ee8eF, amount).

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

   $19 · 1 position

   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. KEEP never swapped to T

   Threshold (KEEP)

   $9 · 1 positionMay not work

5. MKR never converted to SKY

   Maker / Sky

   $6 · 1 positionMay not work

   You hold MKR, or MKR in the old DSChief voting contract, that was never converted to SKY. The converter still works. Its fee is 5% now (read on-chain 2026-10-01) and rises 1 point every 3 months.

   1. Open the Sky app and connect your wallet.
   2. If your MKR is in the old DSChief voting contract, first call free(amount) on that contract.
   3. Approve MKR, then convert it to SKY. You get 24,000 SKY per MKR minus the fee.
   4. Without the app: call mkrToSky(usr, mkrAmt) on the converter 0xA1Ea1bA18E88C381C724a75F23a130420C403f9a.
