Down your limit for the day? Seatbelt closes the door until tomorrow.
max_daily_loss = −5%Guardrails for autonomous trading agents
Point your agent at Robinhood Chain through Seatbelt. It enforces the limits you set, records every decision it makes, and stops the instant you say so — before a bad call becomes a bad day.
Non-custodial · Seatbelt never holds your funds — it only watches the orders your agent tries to place. You keep the keys. You keep the switch.
Live demo: a simulated AI trading agent places orders while Seatbelt allows safe ones and blocks risky ones — oversized positions, disabled options, un-vetted tokens, and daily-loss breaches. Use the kill switch below to halt all activity.
Your agent is smart, fast, and occasionally wrong. These are the walls it cannot cross — enforced on every order, not suggested after the fact.
Down your limit for the day? Seatbelt closes the door until tomorrow.
max_daily_loss = −5%Cap how much of the book any single ticket can take. No 40%-of-everything apes.
max_position = 10%Trade the names you approved. Everything else is a hard no.
allow = [AAPL-x, NVDA-x, …]Before any onchain buy, Seatbelt reads holder concentration and bundling. Sketchy supply, blocked.
reject_if bundle > 30%Toggle whole instrument classes off. If you didn't sign up for 0DTE, neither did your agent.
options = falseAny ticket over your number waits for a tap from you before it goes live.
confirm_above = $5,000Every request your agent makes is logged the moment it happens: what it wanted, what Seatbelt did, and why. When something goes sideways you don't guess — you read the tape. And you get pinged on every block, in real time.
Because the scariest part of an autonomous agent isn't what it does. It's not knowing what it just tried to do.
Seatbelt sits between your agent and the broker. Fair question: why let it? Because it's built to be the one thing in the stack that can't hurt you.
Seatbelt sees the orders your agent tries to place and says yes or no. It can't move funds, withdraw, or trade on its own. Non-custodial, always.
If Seatbelt ever goes offline, your agent doesn't trade unsupervised — it can't trade at all. The absence of a guard is a closed door, not an open one.
The policy engine is open source. Audit exactly what passes and what gets blocked — or self-host it and trust no one but your own machine.
Seatbelt speaks the same protocol your agent already uses. No rebuild, no new SDK.
Swap one URL in your agent's MCP config. Seatbelt sits in front of the broker: mcp.seatbelt.fun
Pick your loss floor, position cap, allowlist and confirm threshold — plain sliders, no code.
Your agent runs as before. Now every order clears your rules first — and you can halt it from your phone.
Access is gated by $BELT on Robinhood Chain. Hold the threshold in your wallet and everything unlocks — connect as many agents as you run. No subscription, no seat count. The token is the key to the door, nothing more.
