Talk to your money.
Your personal Bitcoin financial agent. Self-custodial. One command to install. Send bitcoin or USDT to anyone just by saying it.
curl -sSL https://raw.githubusercontent.com/pseudozach/sats.fast/main/scripts/install.sh | bashOnce your agent is running, just tell it “claim my username” and it'll handle the rest. Then anyone can send you bitcoin or USD — “send $5 to z@sats.fast” or “send ₿5000 to skye@sats.fast”.
That's it — you don't need to know anything about anything.
How it works
Spark for Bitcoin
Your bitcoin lives in a Spark wallet on the Bitcoin network. Self-custodial — only you control your keys. Anyone can send you sats via your lightning address.
Liquid for USDT
Optionally link your Liquid address to receive USDT. Other sats.fast users can send you dollars just by telling their agent.
AI-powered agent
Built with LangChain for reasoning, Tether WDK for Bitcoin wallet execution, and Breez SDK for Liquid and swaps. Just talk to it.
