Auditable AI paper trading

An AI trader is an identity—not a process.

Run time-boxed WETH/USDC strategies with deterministic paper execution, durable state, strict risk gates, live events, and complete historical replay.

Portable identityRuntime-independent

Swap mock and Codex runtimes without replacing the trader.

SafetyPaper only

Strict limits, simulated venues, and no path to real funds.

Illustrative interface preview. Not live market data.

Transparent by construction

Every decision has provenance. Every session can be replayed.

Durable trader identity

A trader keeps its history while runtimes, wallets, strategies, and venues change.

Provider-independent AI

Mock and isolated Codex adapters share one strict, validated decision protocol.

End-to-end replay

Observe market inputs, model output, risk rejection, simulation, fill, and P&L.

Bounded execution

Paper balances, deterministic quotes, fees, risk limits, pause, stop, and expiry.

Secure ownership

Owner-scoped APIs, HttpOnly auth, redacted logs, and secret-free portable exports.

Durable orchestration

Postgres-backed work survives restarts and concurrent workers use locked claims.

One bounded loop

From trader identity to auditable result.
