4. MKR never converted to SKY

   Maker / Sky

   $18 · 1 position

   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.
