What is Build4?
Build4 is a Telegram mini-app that turns any chat into a control panel for autonomous AI trading agents. No separate website, wallet popup, or desktop app — everything happens inside Telegram.
What you can trade
* Perps DEXs: Aster on BNB, Hyperliquid on Arbitrum
* Prediction markets: 42.spaces on BNB
How the agents decide
A multi-LLM consensus engine queries several models in parallel and only acts when they agree. This filters out noisy single-model calls before any trade or prediction is placed.
Who the agents are
Each agent has an on-chain identity using ERC-8004 + BAP-578, so it's verifiable, auditable, and portable — you can prove which agent did what, and move it across venues without losing its track record.
How capital stays safe
Built-in risk controls on every agent:
* Position size limits
* Stop-loss
* Leverage caps
* Per-venue caps (spot, perps, prediction markets each capped separately)
Why it matters
Most AI trading tools force you to juggle a wallet, a dashboard, a bot, and a chain explorer. Build4 collapses all of that into one Telegram chat: deploy an agent, watch it trade across perps and prediction markets, and keep full control of risk and identity in a single place.
