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 source	What it reads	Why it matters
`sbtc-stx-jing-v2` contract (Hiro read-only API)	Cycle ID, phase, blocks elapsed, deposits, minimums	Is the cycle in deposit phase? Is sBTC available?
Pyth Hermes oracle	BTC/USD and STX/USD live prices	Computes 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.

bash

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

Output:

json

  "result": "ready",
  "checks": {
    "hiro_contract_api": "ok",

  },
  "contract": "SPV9K21TBFAK4KNRJXF5DFP8N7W46G4V9RCJDC22.sbtc-stx-jing-v2"
}

status

Fetches full cycle state + price snapshot.

bash

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

Output:

  "summary": "Cycle 9 in deposit phase. Oracle 0.39% MORE EXPENSIVE than DEX."

analyze

Evaluates whether the current cycle offers a favourable entry.

bash

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.

bash

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:

json

{
  "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

Action	Meaning
`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
