Learn-skills.dev jingswap-cycle-agent

JingSwap STX↔sBTC cycle monitor and participation agent. Reads live cycle state and prices directly from the Stacks contract via Hiro API and Pyth oracle — no API key required. Outputs PARTICIPATE / MONITOR / WAIT_FOR_DEPOSIT_PHASE / NO_SBTC_AVAILABLE with oracle-vs-DEX discount analysis.

jingswap-cycle-agent

What it does

Monitors the active JingSwap cycle and evaluates whether the Pyth oracle settlement rate offers a favourable sBTC acquisition opportunity relative to live DEX prices.

Data sourceWhat it readsWhy it matters
sbtc-stx-jing-v2
contract (Hiro read-only API)
Cycle ID, phase, blocks elapsed, deposits, minimumsIs the cycle in deposit phase? Is sBTC available?
Pyth Hermes oracleBTC/USD and STX/USD live pricesComputes oracle STX/sBTC settlement rate
get-dlmm-price
(contract)
DLMM pool price (1e10 / raw)Best DEX rate for comparison
get-xyk-price
(contract)
XYK pool price (raw / 1e8)Secondary DEX rate cross-check

JingSwap settles at the Pyth oracle rate, not the DEX rate. When oracle < DEX, depositing STX acquires sBTC cheaper than buying on-market — the arbitrage window. This skill quantifies that spread in real time.

Why agents need it

JingSwap's API (

faktory-dao-backend.vercel.app
) requires an
x-api-key
. This skill bypasses it entirely by reading the Stacks contract directly via the public Hiro read-only endpoint. No credentials needed.

The

analyze
command distils the cycle state + two price sources into a single
action
field — agents don't need to know the contract encoding or Pyth feed IDs.

Safety notes

  • Read-only for
    doctor
    ,
    status
    ,
    analyze
    — no wallet required.
  • participate
    (without
    --dry-run
    ) outputs a
    DEPOSIT_READY
    JSON payload — parent agent must confirm before calling
    jingswap_deposit_stx
    .
  • Mainnet only — JingSwap v2 contract is mainnet-only.
  • Always uses live contract reads — never caches cycle state.

Commands

doctor

Checks Hiro contract API and Pyth Hermes connectivity.

bun run jingswap-cycle-agent/jingswap-cycle-agent.ts doctor

Output:

{
  "result": "ready",
  "checks": {
    "hiro_contract_api": "ok",
    "pyth_hermes_api": "ok"
  },
  "contract": "SPV9K21TBFAK4KNRJXF5DFP8N7W46G4V9RCJDC22.sbtc-stx-jing-v2"
}

status

Fetches full cycle state + price snapshot.

bun run jingswap-cycle-agent/jingswap-cycle-agent.ts status

Output:

analyze

Evaluates whether the current cycle offers a favourable entry.

bun run jingswap-cycle-agent/jingswap-cycle-agent.ts analyze
bun run jingswap-cycle-agent/jingswap-cycle-agent.ts analyze --min-discount 2.0

Options:

  • --min-discount <pct>
    (default:
    1.0
    ) — minimum oracle discount vs DEX to trigger PARTICIPATE

Output:

  "summary": "MONITOR (high confidence) — cycle 9 (deposit), oracle 0.40% premium vs DEX."
}

participate

Evaluates opportunity and (if favourable) prepares deposit parameters for parent agent execution.

bun run jingswap-cycle-agent/jingswap-cycle-agent.ts participate --amount-stx 100
bun run jingswap-cycle-agent/jingswap-cycle-agent.ts participate --amount-stx 100 --min-discount 2.0 --dry-run

Options:

  • --amount-stx <amount>
    (required) — STX amount to deposit
  • --min-discount <pct>
    (default:
    1.0
    ) — minimum discount required to proceed
  • --dry-run
    — analyse only, do not output execution payload

When favourable, outputs:

{
  "skill": "jingswap-cycle-agent",
  "action": "DEPOSIT_READY",
  "deposit_params": {
    "amount_stx": 100,
    "amount_micro_stx": 100000000,
    "market": "sbtc-stx",
    "cycle": 9
  },
  "instruction": "Parent agent: call jingswap_deposit_stx with amount=100000000 and market=sbtc-stx to execute this deposit. Confirm before proceeding."
}

Action values

ActionMeaning
PARTICIPATE
Oracle < DEX by ≥ min-discount — deposit STX to acquire sBTC below market
MONITOR
Spread present but below threshold — watch and retry
WAIT_FOR_DEPOSIT_PHASE
Cycle is in buffer or settle phase — deposits closed
NO_SBTC_AVAILABLE
No sBTC deposited in current cycle — nothing to acquire

Confidence:

  • high
    — discount ≥ 2% or clearly unfavourable
  • medium
    — discount 1–2%
  • low
    — borderline

  • DLMM price formula:
    STX/sBTC = 1e10 / dlmmRaw
    (contract stores inverse ratio)
  • XYK price formula:
    STX/sBTC = xykRaw / 1e8
    (contract stores direct ratio with 1e8 scale)
  • Oracle price: Pyth Hermes
    BTC/USD ÷ STX/USD = STX/sBTC
  • No API key required for any data source
  • All Hiro reads use sender
