Jingswap Skill
Blind batch auction for swapping sBTC against a quote token on Stacks. Two markets are available:
| Market | Contract | Quote Token |
|---|
| (default) | SPV9K21TBFAK4KNRJXF5DFP8N7W46G4V9RCJDC22.sbtc-stx-jing
| STX |
| SPV9K21TBFAK4KNRJXF5DFP8N7W46G4V9RCJDC22.sbtc-usdcx-jing
| USDCx |
Each auction cycle has three phases: deposit, buffer, settle. Anyone can participate by depositing on either side, and anyone can trigger close/settle/cancel transitions.
