✓ buys a stock 60bps under its official close
✓ sells it +60bps above, or normalizes at the open
✓ stops out at -150bps and halts the day after a $1.5 loss
✗ never exceeds $10 a day or 150bps of impact
✗ never touches venues under $100,000 of liquidity
✗ never widens its own permissions; keys never leave the runner
Every fill writes a receipt. The chain checks it: success, balance deltas, reference, premium. PASS lines print in your browser.

What is Curb?
An autonomous agent for tokenized stocks: it trades the overnight drift and receipts every fill.
Why does the gap exist?
NYSE closes. Solana does not. The official close freezes; the token keeps moving.
Is it trading now?
Yes. The float is funded, the first real fill is executed and its receipt verified on this page, and the agent trades whenever a stock crosses its band.
Could this be a real app?
That is the whole design: a real measured problem, a working end-to-end agent on mainnet, receipts anyone can verify, and fees and limits disclosed on this page.
What stops bad trades?
Hard rails: bands, $10 a day, a 150bps stop, a daily loss halt, slippage refusals.
Can I use it?
xStocks exclude US, UK, Canada and Australia residents; the agent only touches permissionless DEXs.
The tape is already running.
