CoinFello Debuts AI Smart Contract Agent at ETHDenver Conference

CoinFello is rolling out an onchain AI agent at ETHDenver, giving attendees early access to an AI tool that can interact directly with smart contracts through a simple chat experience.

Key Takeaways

• CoinFello is debuting an AI agent that can execute smart contract actions and automate onchain activity through chat.
• ETHDenver attendees get early access through BuffiBot, the event’s official AI assistant inside the ETHDenver app.
• The team says the product is built to make DeFi and onchain execution feel more familiar and safer for everyday users.
• CoinFello is launching as an EIP 8004 agent, opening the door for other AI agents to call it in Ethereum’s agent ecosystem.

What Happened?

CoinFello announced it will debut its onchain AI agent during ETHDenver’s opening ceremonies, with conference attendees receiving exclusive early access. The rollout includes BuffiBot, a preview app that also serves as ETHDenver’s official AI assistant for schedules, speakers, workshops, expo vendors, and side events.

The ETHDenver experience supports both text and real time voice, turning the event’s packed schedule into a single conversational interface.

BuffiBot Turns ETHDenver Into a Chat Interface

For many attendees, large conferences are a maze of overlapping sessions and last minute changes. CoinFello’s answer is BuffiBot, built specifically for ETHDenver and integrated into the ETHDenver app. Users can ask simple questions like where a workshop is happening, which speakers are up next, or what side events are nearby, and get answers without digging through menus.

BuffiBot is designed to handle ETHDenver’s hundreds of sessions and activities by pulling them into one place and presenting them through conversation. The team is positioning the conference deployment as a live proof point, but it is also a way to introduce CoinFello to a crypto native audience that already understands the pain of navigating complex tools.

While BuffiBot remains exclusive to ETHDenver, CoinFello access will continue for attendees after the conference, without requiring them to join the public waitlist.

CoinFello’s Bigger Goal: Make Smart Contracts Feel Human

Beyond conference help, CoinFello is being pitched as an AI application that can explain, execute, and automate interactions with smart contract protocols. Instead of bouncing between browser based decentralized apps, users can describe what they want to do in plain language and let the agent handle the steps.

CoinFello says its system interprets context, executes user defined intents, and manages both synchronous and asynchronous smart contract actions. The promise here is not just convenience, but clarity. Smart contract features often read like developer documentation, and CoinFello is designed to translate that functionality into language regular users can understand.

Another key feature is that the platform analyzes a user’s wallet history to surface relevant tokens, protocols, and potential actions. That could reduce the time people spend searching for the right dApp or digging through token lists. The idea is to bring the experience closer to a modern consumer app, while still supporting self custody and onchain execution.

Built for the Emerging Ethereum Agent Ecosystem

CoinFello is also launching as an EIP 8004 agent, which means it can be called by other AI agents as Ethereum’s agent ecosystem takes shape. That is a notable detail because it suggests CoinFello is not just a standalone product, but could become a building block for more complex agent driven workflows.

The company says it supports EVM compatible networks and uses EigenAI to enable a self custodied AI environment. It also integrates the MetaMask Smart Accounts Kit, aiming to give users more control over how actions get executed and what permissions are granted.

Ryan McPeck, Product Lead at Consensys for the MetaMask Smart Accounts Kit, said:

CoinFello founder JacobC.eth, previously Lead of Operations for MetaMask at ConsenSys, framed the shift as a user experience reset.

Why ETHDenver Matters for This Launch?

ETHDenver is often treated as a testing ground for new Ethereum ideas, and CoinFello is leaning into that vibe. John Paller, Founder of ETHDenver, said:

That quote captures why this launch is getting attention. If onchain agents can safely execute actions on behalf of users, the barriers to using DeFi and other smart contract tools could drop sharply. But it also raises the standard for permissioning, security, and user understanding.

CoinLaw’s Takeaway

I see this as one of the clearest signs that crypto UX is finally moving beyond endless tabs, confusing approvals, and copy paste transactions. In my experience, most people do not quit crypto because they hate the idea, they quit because the tools feel stressful. If CoinFello can genuinely turn smart contract actions into a plain language workflow while keeping users in control, that is a real step toward mainstream use. The big question is how well it handles edge cases, permissions, and user mistakes, because that is where trust is won or lost. Still, ETHDenver is the right place to test it, and BuffiBot is a smart way to show value on day one.
