CoinFello, an AI agent capable of interacting directly with smart contracts, will be introduced to ETHDenver attendees during the conference’s opening ceremonies. The debut provides attendees with early access to CoinFello through BuffiBot, a preview application created by the CoinFello team, and BuffiBot serves as the event’s official AI assistant for conference information. The experience is accessible through the ETHDenver app and supports both text and real-time voice interactions. ETHDenver attendees will receive exclusive access to CoinFello without joining the public waitlist.
BuffiBot synthesizes ETHDenver’s hundreds of sessions and activities into a single conversational interface, illustrating CoinFello’s broader ability to execute and automate onchain actions beyond conference support. The platform analyzes a user’s wallet history to surface relevant tokens and protocols and can be called by other AI agents as an EIP-8004 agent within Ethereum’s growing agent ecosystem.
CoinFello was founded by JacobC.eth, formerly Lead of Operations for MetaMask at ConsenSys. At MetaMask, he helped develop growth and monetization strategies for the Ethereum wallet. The previous model for crypto UX is saturated, said JacobC.eth. Agentic AI enables onchain execution and DeFi interactions to become accessible to billions of people through familiar and safer user experiences. We’re pleased to collaborate with the CoinFello team as they bring agent-driven experiences to users through the MetaMask Smart Accounts Kit, said Ryan McPeck, Product Lead at ConsenSys for the MetaMask Smart Accounts Kit. We see a future where AI agents can safely act on behalf of users using granular, transitive permissions that allow individuals to define how activity is executed on-chain.
ETHDenver has always been where the edges of possibility converge — where builders come to test what the future feels like before the rest of the world catches up. The fusion of decentralized infrastructure and agentic AI signals a new chapter for coordination itself. When humans and autonomous systems co-create in open networks, we expand who can participate and how value is generated. This is the frontier — and it’s unfolding in real time.
CoinFello is an AI agent designed to explain, execute, and automate interactions with smart contracts. Built for self-custody, the platform is currently available in private alpha for end users, with developer versions expected soon. CoinFello supports EVM-compatible networks, leverages EigenAI to enable a self-custodied AI environment, and integrates the MetaMask Smart Accounts Kit to provide users with control over their assets.
