SYSTEM.00agentic trading control planerobinhood

Build agents that trade on Robinhood—with limits you can verify.

HISS turns trading intent into bounded, explainable and verifiable agent behavior across Robinhood brokerage and Robinhood Chain. You set the limits. Your surfaces execute. Every run leaves a receipt.

  • Robinhood Chain: GET /api/status (canonical StatusTruth: RPC probe + committed artifacts, degraded-capable).
  • Bankr rails (deposits · stock tokens): GET /api/agents/schema + SKILL.md Part IV (artifact-derived rail boundaries; rh-wallet is source-pending, BLOCKED, never a dependency).
  • Stock Premium LP: Hosted MCP toolset (SPL tools) + the SPL scanner reads; UNKNOWN halts prepares.
  • Vault V2 (24/7 mesh): GET /api/vaults/v2/status — the typed activation enum, rendered verbatim.
  • Lighter (Robinhood instance): LIGHTER_CURRENT_RUNG in @hiss/core (typed rung ladder) + public reads at /api/lighter/markets · orderbook · depth.
  • Coil compiler: Typed @hiss/core version literals; local MCP toolset pinned by tests; liveOrderSent: false hard-typed.
  • Risk fuses: Static @hiss/core fuse constants (no network, no failure mode).
  • Receipts: @hiss/core/receipts + /app/verify; the on-chain VaultReceiptRegistry read is degraded-capable via /api/status.
  • A failed read renders UNKNOWN — never “live”, never “not deployed”. Degraded reads show the last verified state, labeled.

Every claim on this page is backed by an on-chain read, a committed artifact, or a deterministic receipt — and a failed read says so.

SYSTEM.01from intent to receiptfive stages

Whisper → Coil → Fuses → Execute → Receipt

One pipeline governs every agent action on HISS, from a brokerage rebalance to an onchain ladder.

Deterministic example · fixed inputs · no live data, no balances, no orders

01 · The intent, as stated

"Hold a three-name mega-cap basket. Never let one name exceed 40%. Readiness check only — no orders."

HISS compiles, constrains, prepares, monitors, reconciles, and receipts. Your surfaces sign, submit, place orders, and manage positions.

SYSTEM.02one policy layertwo domains

Two places agents trade. One control plane.

Robinhood brokerage

Built for the Robinhood Trading MCP. Works with your Robinhood Agentic account.

Robinhood’s Agentic account is a dedicated, self-directed account you own — your agent can only place trades there, and you are responsible for them. HISS supplies what the account does not: compiled instructions, enforced bounds, and post-run audits. Readiness check is the default, and every compile artifact carries a hard-typed liveOrderSent: false.

Robinhood currently supports long equities and options orders for agents. Robinhood’s product, limits, and eligibility are Robinhood’s alone.

Robinhood Chain

USDG settlement. Stock Tokens trade 24/7. Your keys sign.

Onchain execution runs through wallets and contracts you control — an EOA, a Safe, or an eligible Bankr session. HISS applies the same Coil, fuse, and receipt discipline to ladders, pools, and vault operations on chain 4663.

HISS-hosted services do not hold Robinhood credentials, Lighter private keys, or unrestricted user signing authority.

SYSTEM.03railsstate-chipped, never assumed

The rails, as they actually are

Each rail renders its live state. Nothing on this board is a promise.

SYSTEM.04flagshiplive agentic liquidity

Stock Premium LP

The flagship agentic-liquidity product: scan Stock-Token premium against synchronized reads, compile a typed, bounded USDG ladder, and execute it from your own keys.

  • Premium, measured

    Synchronized reads across venues surface where Stock-Token prices sit against reference. No projections — measurements.

  • Ladders, bounded

    The compiler emits a typed USDG ladder with integer basis points, hard caps, and an explicit universe. One artifact, one hash.

  • Your keys, your fills

    You review, sign, and submit from a surface you control — Uniswap v3 pools on Robinhood Chain, settled in USDG. The honest net is always shown beside the fees.

USDG vaults on Robinhood Chain

PROOF.07evidencedeterministic

Claims compile into proofs

Three mechanical steps, each one click from the real surface: compile a Coil, verify a receipt, audit a run. Same inputs, same outputs, same hashes — or the check fails loudly.

  1. Compile

    A whisper becomes a Coil: a versioned manifest with integer basis-point weights and an explicit execution mode.

    Open the compiler

  2. Verify

    Recompute any receipt from its inputs. Verification is a function, not a promise.

    Verify a receipt

  3. Audit

    Every artifact carries its provenance: what was produced, what was read, and a hard-typed liveOrderSent: false on compile-only surfaces.

What HISS is — and is not

HISS is the control, policy, and proof layer for agentic trading — compilation and verification software, not advice. HISS compiles, constrains, prepares, monitors, reconciles, and receipts. Surfaces you control — a Robinhood Agentic MCP session, a Robinhood Chain wallet or Safe, an eligible Bankr session, a user-controlled Lighter runtime, or another bounded runtime — sign, submit, place orders, and manage positions. HISS-hosted services do not hold Robinhood credentials, Lighter private keys, or unrestricted user signing authority. HISS is not a vault platform, a staking app, a token dashboard, a portfolio viewer, or an AI trading bot.

  • · HISS is not a broker-dealer, investment adviser, custodian, or order router.
  • · Compile artifacts carry a hard-typed liveOrderSent: false.
  • · Not affiliated with Robinhood, Bankr, or Chainlink.
  • · Autonomous trading involves substantial risk, including loss of principal.
