Jingswap Skill

Blind batch auction for swapping sBTC against a quote token on Stacks. Two markets are available:

Market	Contract	Quote Token
sbtc-stx (default)	SPV9K21TBFAK4KNRJXF5DFP8N7W46G4V9RCJDC22.sbtc-stx-jing	STX
sbtc-usdcx	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.

Usage

bun run jingswap/jingswap.ts <subcommand> [--market <pair>] [options]

All commands accept --market sbtc-stx (default) or --market sbtc-usdcx.

• Deposit phase: min 150 blocks (~5 min) before close
• Buffer phase: 30 blocks (~1 min) after close
• Cancel threshold: 530 blocks (~17.5 min) from close
• distribute events show swap proceeds + unswapped remainder (rolled to next cycle, not refunded)
• Post conditions: deposits use Deny mode; cancel/settle/cancel-cycle use Allow mode
• USDCx is a stablecoin (~$1) — SP120SBRBQJ00MCWS7TM5R8WJNTTKD5K0HFRC2CNE.usdcx, asset usdcx-token, 6 decimals
