# Hermetica Yield Rotator Cross-protocol yield rotator that monitors Hermetica USDh staking APY against Bitflow HODLMM dlmm_1 APR and executes capital rotation to the higher-yielding protocol on Stacks mainnet. ## What it does Queries five Hermetica mainnet contracts (staking-v1, staking-state-v1, staking-silo-v1-1, usdh-token-v1, susdh-token-v1) for the live exchange rate, staking state, cooldown window, and user position. Fetches Bitflow HODLMM dlmm_1 APR and active bin from Bitflow App and Quotes APIs. Tracks the USDh/sUSDh exchange rate in a local state file to estimate APY from ratio changes over time. In assess mode (default), surfaces a HOLD / STAKE / ROTATE_TO_HODLMM / ROTATE_TO_STAKING recommendation. In write mode (with --confirm), outputs MCP tool commands to execute the recommended action. **Rotation logic:** rotates when yield differential exceeds 2% threshold. HODLMM preferred → initiates Hermetica unstake (7-day cooldown), then swaps USDh → USDCx (dlmm_1 accepts USDCx, not USDh) and deploys to HODLMM. Staking preferred → removes HODLMM bins, stakes in Hermetica. Idle USDh → swaps to USDCx then deploys to best-yielding protocol immediately. **30-minute rotation cooldown** prevents thrashing. All write actions require `--confirm`. ## Why agents need it USDh staking yield and HODLMM LP fees move independently. Without active rotation, agents leave yield on the table when market conditions shift. This skill closes that gap: a single `--action=rotate --confirm` re-allocates capital to the optimal protocol based on live data. ## Safety notes - **500 USDh autonomous spend cap — hardcoded in code.** Without explicit `--amount`, stake/unstake/rotate operations are capped at 500 USDh regardless of wallet balance. Pass `--amount` to operate on larger positions. - **Doctor-first preflight enforced in code:** write actions verify Hermetica contract and staking state are reachable before executing. Aborts with `PREFLIGHT_FAILED` if sources are down. - All write actions require explicit `--confirm` flag — no accidental execution - 2% minimum differential threshold prevents unnecessary rotation on noise - 30-minute cooldown between rotations tracked in local state file - Balance checked before stake/initiate-unstake — rejects if insufficient - Rotation blocked if APY data unavailable (< 1h of exchange rate history) - Rotation cooldown checked before execution - `initiate-unstake` always reports 7-day cooldown so agent can plan `complete-unstake` ## Output Contract All outputs are strict JSON to stdout: ```json { "status": "success | error", "action": "HOLD | STAKE | ROTATE_TO_HODLMM | ROTATE_TO_STAKING | INITIATE_UNSTAKE | COMPLETE_UNSTAKE | CHECK | Blocked: <reason>", "data": { "mcp_commands": "[McpCommand[] | null] — present on write actions", "staking_enabled": "boolean", "exchange_rate": "number", "accumulated_yield_pct": "number", "estimated_apy_pct": "number | null", "cooldown_days": "number", "hodlmm_apr_pct": "number | null", "hodlmm_active_bin": "number | null", "yield_comparison": "string | null", "user_usdh": "number | null", "user_susdh": "number | null", "rotation_cooldown_ok": "boolean", "rotate_threshold_pct": "number" }, "error": "null | { code, message, next }" } ``` ## Prerequisites This skill requires the AIBTC MCP server for all on-chain interactions: ```bash npx @aibtc/mcp-server@latest --install ``` ## Commands ### doctor ```bash bun run hermetica-yield-rotator/hermetica-yield-rotator.ts doctor ``` ### install-packs ```bash bun run hermetica-yield-rotator/hermetica-yield-rotator.ts install-packs --pack all ``` ### run — assess (read-only, no --confirm needed) ```bash bun run hermetica-yield-rotator/hermetica-yield-rotator.ts run --wallet SP1234... ``` ### run — stake ```bash bun run hermetica-yield-rotator/hermetica-yield-rotator.ts run \ --wallet SP1234... --action=stake --amount=500 --confirm ``` ### run — initiate-unstake ```bash bun run hermetica-yield-rotator/hermetica-yield-rotator.ts run \ --wallet SP1234... --action=initiate-unstake --amount=500 --confirm ``` ### run — complete-unstake ```bash bun run hermetica-yield-rotator/hermetica-yield-rotator.ts run \ --wallet SP1234... --action=complete-unstake --confirm ``` ### run — rotate (auto-rotate to best yield) ```bash bun run hermetica-yield-rotator/hermetica-yield-rotator.ts run \ --wallet SP1234... --action=rotate --confirm ``` ## Live terminal output ### doctor ```json { "status": "ok", "checks": [ { "name": "Hermetica staking-v1", "ok": true, "detail": "exchange rate: 1.00000000 USDh/sUSDh" }, { "name": "Hermetica staking-state-v1", "ok": true, "detail": "staking enabled: true, cooldown: 7.0 days" }, { "name": "Hermetica token contracts (USDh + sUSDh)", "ok": true, "detail": "USDh supply: $9,049,413.13, sUSDh: 1,836,203.38" }, { "name": "Bitflow HODLMM App API (dlmm_1)", "ok": true, "detail": "APR: 17.72%, TVL: $77,143" }, { "name": "Bitflow HODLMM Bins API (dlmm_1)", "ok": true, "detail": "active bin: 504" } ], "message": "All data sources reachable.

The swap step is required because dlmm_1 accepts USDCx, not USDh. ## Data sources | Source | Data | Endpoint | |---|---|---| | Hermetica staking-v1 | Exchange rate | `SPN5AK…HSG.staking-v1::get-usdh-per-susdh` | | Hermetica staking-state-v1 | Staking enabled, cooldown | `::get-staking-enabled`, `::get-cooldown-window` | | Hermetica staking-silo-v1-1 | Epoch timestamp | `::get-current-ts` | | Hermetica usdh-token-v1 / susdh-token-v1 | Token supplies | `::get-total-supply` | | Hiro Address API | User FT balances | `api.mainnet.hiro.so/extended/v1/address/{addr}/balances` | | Bitflow HODLMM App API | dlmm_1 APR, TVL, user position bins | `bff.bitflowapis.finance/api/app/v1/pools`, `/users/{addr}/positions/{pool}/bins` | | Bitflow HODLMM Quotes API | Active bin ID | `bff.bitflowapis.finance/api/quotes/v1/bins/{pool}` | ## Origin Winner of AIBTC x Bitflow Skills Pay the Bills competition.
