# CoinFello

> CoinFello is a self-custodial, always-on AI agent for DeFi. It researches, executes,
> and automates any smart-contract interaction from plain-language chat (send, swap,
> bridge, stake, earn yield, and run multi-step strategies) while users keep full
> custody of their keys. Private keys stay in the user's wallet; the agent acts only
> within guardrails the user sets (spending limits, allowed tokens, expiry dates) and
> can be revoked at any time.
