The trading interface
for coding agents.

Give an agent a mandate in plain English. T3 Trade holds it to hard limits and signs every order locally.

Watch one mission run.

A mission binds one agent thread to one market. This is the cockpit itself, replaying a testnet ETH run: keep scrolling and the log fills, the watch fires, the checks pass, and the chart earns its target.

The exchange is the source of truth

Positions, orders, and fills are re-read from Hyperliquid after every submission, fill, reconnect, and restart. Local records never override it.

Risk is counted before entry

Realised loss, paid fees, protected open risk, and pending-entry risk all draw down the same budget. Exhaust it and new exposure is blocked while stops stay in place.

The stop is not advisory

It rests on Hyperliquid as a reduce-only order, and its size is reconciled against the position the exchange reports. It survives the app closing.

Live mid prices from Hyperliquid testnet, the only network this alpha talks to. Testnet funds have no real-world value and there is no mainnet configuration.

Every entry passes the same seventeen checks.

Before signing a position-increasing order, T3 Trade re-checks mission status, authority, agent lease, direction, signer approval, data freshness, size, price, exchange minimums, leverage, notional, per-position risk, the loss budget, pending conflicts, and the stop. One failure rejects the order.

  • Every position increase carries a stop. T3 Trade submits an exchange-native reduce-only stop, then reconciles its size against the position Hyperliquid reports.
  • A retry is the same order. The client order ID and local request key are deterministic, so a resubmission cannot open a second position.
  • You keep the controls. Pause, cancel entries, reduce, close, and revoke all work with the agent CLI stopped.

T3 Trade drives five CLIs already installed and authenticated on your machine. Three of them can run trading missions today. None of them ever receives the signer key.

No valid signer keyExecution is disabled. Every action that needs a signature is rejected.
Valid key loadedExecution is enabled for the Hyperliquid testnet account derived from that key.

Execution needs one local testnet key.

This alpha has no wallet onboarding. Put a single 32-byte EVM private key for a Hyperliquid testnet account in ~/.t3trade/secrets. T3 Trade derives the address, holds the raw key in server memory, and signs orders locally with it. The key is never written to logs, reports, or the database. Use a testnet-only key.

What ships in this alpha.

The macOS build is Apple Silicon only and is not notarized, so a downloaded copy is quarantined and macOS may refuse to open it. The installer above fetches the same DMG and clears that flag. To do it by hand, drag the app to Applications and run:

xattr -dr com.apple.quarantine "/Applications/T3 Trade (Alpha).app"
