Our Active Projects

From protocols to runtimes to trained models — these are the projects we build and use in production.

XCT Applied · On-Chain

Golden Hen Suite

XCT taken to its extreme — three self-custody engines for managing wealth on-chain, where the model steps out of the hot path entirely. Harvest accumulates SOL from volatility; Treasury preserves it; Pirate hunts asymmetric bets. Deterministic pipelines execute, the model supervises, and the books reconcile against the blockchain, cent for cent.

Why It Matters

  • The model out of the execution path — determinism runs the money
  • Four-term ledger that reconciles with on-chain reality (gas + dust)
  • SOL-first: accumulates SOL from volatility, not directional bets
  • Self-custody appliance — the client's box, wallet, and keys

Trained Model

XCT-Qwen3-4B

An execution-oriented language model fine-tuned with LoRA to operate under the XCT Protocol. Not a conversational assistant — a constrained execution engine for controlled, deterministic systems.

Deterministic Agent

Polaris v3

This is not a chatbot — it's a deterministic execution agent powered by the XCT Protocol. The model proposes one action at a time, the system validates, deterministic tools execute. Designed to be customized to your use case: each deployment gets its own tool set, validation rules, and execution boundaries tailored to the problem at hand. Built for critical automation where reliability is non-negotiable.

Protocol

XCT — Execution Control Transfer

An architectural protocol that keeps language models from granting themselves executive authority. XCT inverts the sovereignty model: models propose, but don't execute. Control remains with deterministic tools. Born from production experience with high-risk AI deployments.

Protocol Principles

  • No action without explicit tool invocation
  • One step per iteration — controlled loop
  • Errors are first-class control signals
  • System has veto power over any proposal
  • Ambiguity resolves to minimal action

Why XCT Exists

XCT is not a prompt style or agent framework — it's an architectural protocol. Traditional AI integrations let models decide what to do and when. XCT inverts this: the model proposes, the system validates, deterministic tools execute. Authority remains external by design.
