Learn-skills.dev hodlmm-bin-guardian

Monitors Bitflow HODLMM bins to keep LP positions in the active earning range. Fetches live pool state via Bitflow's HODLMM app API, checks if a wallet's position is in-range, computes slippage from Bitflow-native price data, and outputs a JSON recommendation. Read-only — rebalance actions require explicit human approval.

HODLMM Bin Guardian

Monitors Bitflow HODLMM (DLMM) bins to keep LP positions in the active earning range.

What it does

Fetches live Bitflow HODLMM pool state, the user's actual LP position bins (via wallet address), and compares the user's bin range against the active bin to determine if the position is earning fees. Volume, TVL, APR, and token prices are sourced directly from Bitflow's HODLMM app API — no external oracles. Slippage is measured as the deviation between the HODLMM active-bin price and Bitflow's own reported token price. Also checks estimated gas cost and cooldown before recommending REBALANCE.

Why agents need it

HODLMM positions stop earning fees the moment the market price moves outside the deposited bin range. This skill gives an autonomous agent a reliable, safe-to-run check that surfaces out-of-range positions and flags them for human-approved rebalancing — without ever spending funds autonomously.

Safety notes

Read-only. No transactions are submitted.
Mainnet-only. Bitflow HODLMM API does not support testnet.
Refuses to recommend rebalance if 24h pool volume < $10,000 USD.
Refuses to recommend rebalance if slippage > 0.5% (HODLMM bin price vs Bitflow app price).
Any actual rebalance (add/withdraw liquidity) requires explicit human approval before execution.
All price data sourced from Bitflow APIs only — no external oracles.

Commands

doctor

Checks all data sources: Bitflow HODLMM API, Bitflow Bins API, Bitflow App Pools API, and Hiro Stacks API.

bun run hodlmm-bin-guardian/hodlmm-bin-guardian.ts doctor

install-packs

No additional packs required — uses Bitflow and Hiro public HTTP APIs directly.

bun run hodlmm-bin-guardian/hodlmm-bin-guardian.ts install-packs

run

Checks the LP position in the default sBTC HODLMM pool (dlmm_1) and outputs a recommendation. Pass

--wallet

to enable the real in-range check against actual position bins.

# Full check with wallet (recommended)
bun run hodlmm-bin-guardian/hodlmm-bin-guardian.ts run --wallet SP1234...
bun run hodlmm-bin-guardian/hodlmm-bin-guardian.ts run --wallet SP1234... --pool-id dlmm_1

# Pool-only check (no position check — in_range will be null)
bun run hodlmm-bin-guardian/hodlmm-bin-guardian.ts run

v2 changelog (fixes from day-1 review)

In-range check — was fake, now real

Before:

inRange = isFinite(pool.active_bin) && pool.active_bin > 0

— always

true

After: Real HTTP call to

GET /api/app/v1/users/{address}/positions/{poolId}/bins

. Filters bins where

user_liquidity > 0

, checks if

active_bin_id

is in that set.

Slippage — was hardcoded, now live and fully Bitflow-native

Before: Constant value, always passed.

After:

(bin_price_raw / 1e8) × 10^(xDec − yDec)

vs Bitflow app API token price. No external oracles — all data from Bitflow endpoints.

Gas estimate — was a made-up constant, now live

Before:

gas_estimated_stx: 0.006

— hardcoded.

After:

Hiro /v2/fees/transfer × 500 bytes × 2 txns × 3× contract multiplier × 1.2 safety buffer

Cooldown — was not tracked, now persistent

Before: No state file, cooldown always passing.

After: Reads/writes

~/.hodlmm-guardian-state.json

. Returns

cooldown_remaining_h

on each run.

Frontmatter — stale dependency removed

Before:

requires: [bitflow]

— referenced a non-existent dependency.

After:

requires: ""

— fully self-contained, all data from public HTTP APIs.
