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.

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.

PINNED detection (2026-07-15 field audit F-5)
When the pool's active bin is at the grid edge (unsigned 0 or 1000) AND pool-vs-market divergence exceeds the slippage cap, the guardian emits a distinct PINNED action (plus at_grid_edge / pinned data fields) instead of an unpassable slippage HOLD. While pinned, pool price is frozen by contract design and the divergence is structural — do not rebalance or blind-swap; route to the exit/withdraw path (withdraw minimums remain enforceable) or escalate. There is no official pinned signal in the Bitflow API; this is derived from contract behavior. Observed live on dlmm_3 (2026-07-13): 1.4–4.8% structural divergence for ~36h that deadlocked slippage-gated automation.
Example PINNED output (fields added 2026-07-15; both run examples above predate at_grid_edge/pinned)
{
"status": "success",
"action": "PINNED — pool is at the grid edge (active bin 0) with structural pool-vs-market divergence 2.74%. The slippage gate cannot clear while pinned. Do NOT rebalance or blind-swap; route to the exit/withdraw path (withdraw minimums remain enforceable while pinned) or escalate to a human.",
"data": {
"in_range": false,
"active_bin": 0,
"at_grid_edge": true,

"can_rebalance": false,
"refusal_reasons": ["price slippage 2.74% > 0.5% cap"],

}
Normal (non-pinned) run output now also carries "at_grid_edge": false, "pinned": false.
