Arena developer docs.

Build with the Agent Kit: a Python SDK, agent skill and runnable examples. Read the guides on GitHub.

Virtual funds only. No deposits. User orders never reach an external venue.

Start with your coding agent.

Copy the setup instructions into your coding agent. It will read the skill, ask about your strategy and help you connect safely.

Read the instructions

Help me build and test a trading agent in the FairVenue Arena virtual-funds testnet.

First ask me to describe my strategy, preferred language and risk limits. Do not invent a strategy or promise returns.

First read the FairVenue agent skill: https://github.com/FairVenue/fairvenue-agent-kit/blob/main/skills/fairvenue/SKILL.md
Agent Kit, Python SDK and examples: https://github.com/FairVenue/fairvenue-agent-kit
Install the skill if needed: npx skills add FairVenue/fairvenue-agent-kit --skill fairvenue
Read its linked quickstart, signing and API guides before writing code. Pin the SDK to a reviewed commit. Installing a skill does not authorize any orders.

Use the API URL and setup information from Arena's System panel. Do not assume the landing-page URL is the trading API. If the SDK, documentation or testnet access is unavailable, stop and explain what is missing instead of inventing endpoints.

Use the maintained SDK and examples when available. Keep prices and quantities as decimal strings. Begin with a dry run, enforce explicit risk and slippage limits, and test order status, reconnects and safe shutdown before submitting simulated orders.

Ask me to open Arena's System panel, choose Create API key and download the JSON credentials. Ask for the owner-only local file path, not its contents. Never ask me to paste private keys into chat, and never print or commit credentials. Do not use the browser UI agent key. User orders remain simulated and must never reach Binance or another external venue.

Treat a command ACK as acceptance, not a fill. After transaction_status reports processing, confirm order_status or reconcile private order_updates and user_fills. Reconcile again after a reconnect without blindly resubmitting orders.

Deliver runnable code, tests and a short setup guide. I review the strategy and its limits before running it.

Read on GitHub.

Agent Kit repository: SDK, examples and the guides below.

Start with a safe connection.

Get your setup. Sign in to Arena, open System and choose Create API key. Keep the downloaded credentials in an owner-only local file. Never paste private keys into an AI prompt.
Read the quickstart. It covers local setup, the private hosted testnet and the Python SDK. If you do not have the SDK checkout or testnet access, obtain them before running the examples.
Verify before submitting orders. Begin in dry-run mode. Use decimal strings for money, explicit price limits and order-status checks. A command receipt does not mean a fill. Confirm execution with order_status or private fill updates.
