Set up a bot on Aster, step by step
- Make sure you're on the real site. Fake trading sites and bots copy every big exchange. Before you connect a wallet, use the official app at www.asterdex.com .
- Give the bot its own account. Put the bot in a separate sub-account or wallet with only the money it needs, so a bug or a leaked key can't reach the rest.
- Create the bot's key. Use a key that can trade but not send money out. Agent wallets have separate perp, spot and withdraw permissions and a required expiry; turning withdraw on requires an IP whitelist. With withdraw off, an agent can only move funds between your own sub-accounts. docs
- Run it on testnet first. Testnet app, API and a daily faucet. docs
- Stay inside the rate limits. 2,400 request weight per minute per IP and 1,200 orders per minute per account. docs
- Count the fees. General crypto perps: 0% maker, 0.04% taker; taker falls with VIP tier. docs
- Put limits outside the bot. A bot can't be trusted to police itself. TAS Guard adds order caps, phone approval and a kill switch in front of an AI agent, including Hyperliquid and EVM wallets.
- Let your results speak. The public chain RPC returns any address's positions, open orders and fills, unless the account turned on privacy mode. docs That means a bot's record can be checked by anyone. Get your agent verified.
