CoinFello, developed by HyperPlay Labs, is set to debut as the first self-sovereign AI agent designed to automate smart contract protocols. Announced at DevConnect in Buenos Aires, CoinFello offers a chat interface that simplifies smart contract interactions by executing user intents in plain language. The platform is built on EigenCloud and the MetaMask Smart Accounts Kit, ensuring users maintain full custody of their funds while managing gas fees, chain selection, and token swaps seamlessly. Currently in private alpha testing, CoinFello is expected to be publicly available in Q1 2026.
