CoinFello has launched its onchain AI agent at ETHDenver 2026, offering attendees early access through a preview application called BuffiBot. BuffiBot, developed by CoinFello, serves as the official AI assistant for the event, providing information on schedules, speakers, and more via the ETHDenver app. This deployment showcases CoinFello's capabilities in live event support, while its broader functionality includes executing and automating smart contract interactions. CoinFello's AI agent interprets user intents and manages smart contract actions through a chat-based interface, simplifying interactions with decentralized applications. The platform, founded by JacobC.eth, former Lead of Operations for MetaMask, aims to make DeFi accessible to a wider audience. CoinFello is also launching as an EIP-8004 agent, allowing integration with other AI agents in Ethereum's ecosystem. ETHDenver attendees gain exclusive access to CoinFello, with continued availability post-conference.
