Stacking Skill

• get-pox-info and get-stacking-status — Read-only, no wallet required.
• stack-stx and extend-stacking — Write operations, require an unlocked wallet.

Usage

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

get-stacking-status

bun run stacking/stacking.ts get-stacking-status [--address <addr>]

• --address

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

{
  "address": "SP2...",
  "network": "testnet",
  "stacked": true,
  "amountMicroStx": "100000000000",

bun run stacking/stacking.ts stack-stx \
  --amount <microStx> \
  --pox-address-version <version> \
  --pox-address-hashbytes <hex> \
  --start-burn-height <btcBlockHeight> \
  --lock-period <cycles>

• --amount

  (required) — Amount of STX to stack in micro-STX (1 STX = 1,000,000 micro-STX). Must meet the minimum stacking threshold.

• --pox-address-version

  (required) — Bitcoin address version byte:

  0

  (P2PKH),

  1

  (P2SH),

  4

  (P2WPKH),

  5

  (P2WSH),

  6

  (P2TR)

• --pox-address-hashbytes

  (required) — Bitcoin address hash bytes as a hex string (20 bytes for P2PKH/P2SH/P2WPKH, 32 bytes for P2WSH/P2TR)

• --start-burn-height

  (required) — Bitcoin block height at which stacking begins (must be in a prepare phase or the first block of a reward phase)

• --lock-period

  (required) — Number of reward cycles to lock STX (1–12)

{
  "success": true,
  "txid": "abc123...",
  "stacker": "SP2...",
  "amount": "100000000000",
  "lockPeriod": 3,
  "startBurnHeight": 850000,
  "network": "testnet",
  "explorerUrl": "https://explorer.hiro.so/txid/abc123...?chain=testnet"
}

extend-stacking

bun run stacking/stacking.ts extend-stacking \
  --extend-count <cycles> \
  --pox-address-version <version> \
  --pox-address-hashbytes <hex>

• --extend-count

  (required) — Number of additional reward cycles to lock (1–12)

• --pox-address-version

  (required) — Bitcoin address version byte (same as used when initially stacking)

• --pox-address-hashbytes

  (required) — Bitcoin address hash bytes as a hex string (same as used when initially stacking)

{
  "success": true,
  "txid": "abc123...",
  "stacker": "SP2...",
  "extendCount": 2,
  "network": "testnet",
  "explorerUrl": "https://explorer.hiro.so/txid/abc123...?chain=testnet"
}

Notes

• The minimum stacking amount varies by cycle. Use

  get-pox-info

  to check

  minAmountUstx

  before calling

  stack-stx

  .
• Bitcoin reward addresses are specified as version + hashbytes (raw hash, not base58check encoded). To derive these from a Bitcoin address, use a library or the

  wallet

  skill's

  get-taproot-address

  for Taproot addresses.

• lock-period

  of 1–12 cycles is valid. Each cycle is typically ~2 weeks on mainnet.

• start-burn-height

  must fall within the prepare phase of the current PoX cycle. Check

  nextCycle.prepare_phase_start_block_height

  from

  get-pox-info

  .
• Wallet operations require an unlocked wallet (use

  bun run wallet/wallet.ts unlock

  first).
