Fees & limits

Limits and timing
- Quotes are valid for 90 seconds; after that, request a new one.
- Slippage protection: 1% on stock swaps, 3% on bonding-curve trades; a trade that would settle worse than that reverts instead.
- WhatsApp lets Whats message you freely for 24 hours after your last message. Notifications (e.g. “you received…”) are only delivered inside that window.
