dual-stacking（双堆叠）

Dual Stacking Skill

Dual Stacking lets agents earn BTC-denominated yield (paid in sBTC) simply by holding sBTC — no lockup period required. Optionally, holding stacked STX alongside sBTC unlocks a multiplier of up to 10x on the APR.

• check-status — Read-only. Returns enrollment state, APR range, minimum amount, and cycle overview.
• get-rewards — Read-only. Returns earned rewards for a specific cycle.
• enroll and opt-out — Write operations, require an unlocked wallet.

Contract: SP1HFCRKEJ8BYW4D0E3FAWHFDX8A25PPAA83HWWZ9.dual-stacking-v2_0_4

APR:

• sBTC only: ~0.5% APY in sBTC
• sBTC + stacked STX: up to ~5% APY (10x multiplier)

Minimum enrollment: 10,000 sats sBTC (0.0001 sBTC)

Usage

bun run dual-stacking/dual-stacking.ts <subcommand> [options]

Subcommands

check-status

Check enrollment status, APR data, minimum enrollment amount, and current cycle overview for an address.

bun run dual-stacking/dual-stacking.ts check-status [--address <STX_ADDRESS>]

Options:

• --address (optional) — Stacks address to check (uses active wallet if omitted)

Output:

{
  "address": "SP2...",
  "network": "mainnet",
  "enrolledThisCycle": true,
  "enrolledNextCycle": true,
  "minimumEnrollmentSats": 10000,
  "apr": {
    "minApr": 0.5,
    "maxApr": 5,
    "unit": "%",
    "note": "Multiplier up to 10x with stacked STX via PoX"
  },
  "cycleOverview": {
    "currentCycleId": 100,
    "snapshotIndex": 3,
    "snapshotsPerCycle": 144
  }
}

enroll

Enroll in Dual Stacking. The caller's sBTC balance is used to determine rewards. Optionally, a different address can receive the rewards.

bun run dual-stacking/dual-stacking.ts enroll [--reward-address <STX_ADDRESS>]

Options:

• --reward-address (optional) — Stacks address to receive rewards (defaults to caller's address)

Output:

{
  "success": true,
  "txid": "abc123...",
  "enrolledAddress": "SP2...",
  "rewardAddress": "SP2...",
  "network": "mainnet",
  "explorerUrl": "https://explorer.hiro.so/txid/abc123...?chain=mainnet"
}

opt-out

Opt out of Dual Stacking. Takes effect from the next cycle.

bun run dual-stacking/dual-stacking.ts opt-out

Output:

{
  "success": true,
  "txid": "abc123...",
  "address": "SP2...",
  "network": "mainnet",
  "explorerUrl": "https://explorer.hiro.so/txid/abc123...?chain=mainnet"
}

get-rewards

Get earned rewards for a specific cycle and address.

bun run dual-stacking/dual-stacking.ts get-rewards --cycle <N> [--address <STX_ADDRESS>] [--rollback <N>]

Options:

• --cycle (required) — Cycle number to query
• --address (optional) — Stacks address to check (uses active wallet if omitted)
• --rollback (optional) — Rollback offset (default: 0)

Output:

{
  "address": "SP2...",
  "cycle": 99,
  "rollback": 0,
  "rewardSats": 500,
  "rewardBtc": "0.000005",
  "network": "mainnet"
}

Notes

• Enrollment is per-cycle. If you enroll mid-cycle, rewards start from the next cycle.
• The reward multiplier is determined automatically based on how much STX you have stacked via PoX.
• Use the stacking skill to stack STX and boost your Dual Stacking APR up to 5% APY.
• Wallet operations require an unlocked wallet (use bun run wallet/wallet.ts unlock first, or set CLIENT_MNEMONIC env var).
