# Aster trading bot setup (2026): keys, testnet, fees and limits

Order-book perps and spot on Aster Chain, Aster's own chain; deposits come in through bridge contracts on BNB Chain, Ethereum, Arbitrum, Solana and Sui. Here's how to run a trading bot or AI agent on it without handing it more power than it needs. Every fact links Aster's own docs, checked Oct 30, 2026.

**Watch out:** Its terms ban bots and automated access without Aster's express permission, even though it ships an API and agent tools.

## Set up a bot on Aster, step by step

1. **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](https://tradingagentstack.com/go/aster/?from=/aster-trading-bot/) Referral link where available · [disclosure](https://tradingagentstack.com/disclosure/).

2. **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.

3. **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](https://github.com/asterdex/api-docs/blob/master/V3(Recommended)/EN/aster-finance-futures-api-v3.md)

4. **Run it on testnet first.** Testnet app, API and a daily faucet. [docs](https://docs.asterdex.com/aster-chain/testnet)

5. **Stay inside the rate limits.** 2,400 request weight per minute per IP and 1,200 orders per minute per account. [docs](https://github.com/asterdex/api-docs/blob/master/V3(Recommended)/EN/aster-finance-futures-api-v3.md)

6. **Count the fees.** General crypto perps: 0% maker, 0.04% taker; taker falls with VIP tier. [docs](https://docs.asterdex.com/trading/perpetuals/fees-and-specs/fees)

7. **Put limits outside the bot.** A bot can't be trusted to police itself. [TAS Guard](https://tradingagentstack.com/guard/) adds order caps, phone approval and a kill switch in front of an AI agent, including Hyperliquid and EVM wallets.

8. **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](https://github.com/asterdex/api-docs/blob/master/RPC/aster-chain-rpc.md) That means a bot's record can be checked by anyone.
