What this skill does


# 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`.

## Subcommands

### cycle-state

Get current auction cycle state (phase, blocks elapsed, totals, minimums).

```
bun run jingswap/jingswap.ts cycle-state --market sbtc-usdcx
```

### depositors

Get quote-token and sBTC depositors for a cycle.

```
bun run jingswap/jingswap.ts depositors --cycle <number> --market sbtc-stx
```

### user-deposit

Get a user's deposit amounts for a cycle.

```
bun run jingswap/jingswap.ts user-deposit --cycle <number> --address <stx_address>
```

### settlement

Get settlement details for a completed cycle.

```
bun run jingswap/jingswap.ts settlement --cycle <number>
```

### cycles-history

Get full history of all auction cycles.

```
bun run jingswap/jingswap.ts cycles-history --market sbtc-usdcx
```

### user-activity

Get a user's auction activity (deposits, cancellations, fills, rollovers).

```
bun run jingswap/jingswap.ts user-activity --address <stx_address> --market sbtc-usdcx
```

### prices

Get oracle and DEX prices (Pyth, XYK pool, DLMM).

```
bun run jingswap/jingswap.ts prices
```

### deposit-stx

Deposit quote token (STX or USDCx depending on market) into the current auction cycle. Deposit phase only.

```
bun run jingswap/jingswap.ts deposit-stx --amount 10 --market sbtc-usdcx
```

### deposit-sbtc

Deposit sBTC (in satoshis) into the current auction cycle. Deposit phase only.

```
bun run jingswap/jingswap.ts deposit-sbtc --amount 10000 --market sbtc-usdcx
```

### cancel-stx

Cancel your quote-token deposit and get a refund. Deposit phase only.

```
bun run jingswap/jingswap.ts cancel-stx --market sbtc-usdcx
```

### cancel-sbtc

Cancel your sBTC deposit and get a refund. Deposit phase only.

```
bun run jingswap/jingswap.ts cancel-sbtc
```

### close-deposits

Close the deposit phase (requires min 150 blocks elapsed, both sides above minimum).

```
bun run jingswap/jingswap.ts close-deposits --market sbtc-usdcx
```

### settle

Settle using stored Pyth prices (free). Usually fails due to stale prices — prefer settle-with-refresh.

```
bun run jingswap/jingswap.ts settle
```

### settle-with-refresh

Settle with fresh Pyth VAAs (~2 uSTX). Recommended settlement method.

```
bun run jingswap/jingswap.ts settle-with-refresh --market sbtc-usdcx
```

### cancel-cycle

Cancel cycle if settlement failed after 530 blocks (~17.5 min). Rolls deposits to next cycle.

```
bun run jingswap/jingswap.ts cancel-cycle
```

## Notes

- Stacks blocks average ~2 seconds (Nakamoto)
- 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
