Fello provides a self‑custodial AI agent that automates any DeFi smart‑contract interaction while keeping users’ private keys in their own wallets. Users set granular guardrails—spending limits, allowed tokens, and expiry dates—and the agent explains each transaction in plain language before execution, ensuring safety and transparency. Built to run in a Trusted Execution Environment, Fello enables natural‑language‑driven swaps, staking, liquidity provision, and complex multi‑step strategies without exposing wallet keys.

Problem
DeFi users must manually interact with each smart contract, which is time‑consuming and error‑prone, while existing automation tools often require handing over private keys or rely on centralized services, exposing users to security and custody risks.
Solution
CoinFello offers a self‑custodial AI agent that can execute any DeFi smart‑contract interaction on behalf of the user. The agent operates within on‑chain delegations that enforce granular guardrails such as per‑token spending limits, allowed token lists, and time‑bound expirations. Users retain full control of their private keys; the agent never holds them and can only act after the user approves each transaction in their wallet. Before execution, the agent reads the contract code and presents a plain‑language explanation of the action and its risks, ensuring transparent decision‑making. The service runs continuously in a trusted execution environment, enabling automated strategies like swaps, staking, liquidity provision, and multi‑step workflows while remaining revocable at any time.
Target Audience
Primary users are individual DeFi participants and crypto traders who want secure, automated on‑chain actions, as well as developers building AI‑driven products that need a non‑custodial execution layer.
