[PRESS RELEASE – Denver, Colorado, February 18th, 2026]
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 a special preview application called BuffiBot, created by the CoinFello team.
For ETHDenver, CoinFello developed BuffiBot as the event’s official AI assistant for conference information. Attendees can ask about schedules, speakers, workshops, expo vendors, and side events. The experience is accessible through the ETHDenver app and supports both text and real-time voice interactions.
BuffiBot synthesizes ETHDenver’s hundreds of sessions and activities into a single conversational interface. While the ETHDenver deployment highlights a live event use case, CoinFello’s broader functionality extends beyond conference support.
CoinFello is designed as an AI application for executing and automating interactions with smart contract protocols. Through a chat-based interface, the agent interprets context, executes user-defined intents, and manages both synchronous and asynchronous smart contract actions. The system is built to present smart contract functionality in plain language.
The platform analyzes a user’s wallet history to surface relevant tokens, protocols, and potential actions, reducing reliance on traditional browser-based decentralized applications. CoinFello is also launching as an EIP-8004 agent, enabling it to be called by other AI agents within Ethereum’s emerging agent ecosystem.
CoinFello was founded by JacobC.eth, previously 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 attendees will receive exclusive access to CoinFello without joining the public waitlist. Access to CoinFello will continue following the conference, while the BuffiBot experience remains exclusive to ETHDenver.
“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,” said John Paller, Founder of ETHDenver. “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.”
About CoinFello
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.
