CoinFello CEO on AI Agents for Ethereum and DeFi

At ETH Denver, Jacob C. laid out a clear thesis: the next wave of crypto products will not just explain smart contracts, they will execute them. His company, CoinFello, is building a general-purpose AI agent designed to help users interact with Ethereum through natural language, with less friction and more safety.

That vision fits the energy of ETH Denver, one of the most important gatherings for Ethereum builders. For more context on the event, see ETH Denver’s official site and the broader Ethereum ecosystem at Ethereum.org.

Why ETH Denver Still Matters

Jacob described Denver as a place where Ethereum’s original spirit still feels alive: weird, experimental, and builder-first. That matters because products like CoinFello need a community that is willing to test new interfaces and new trust models.

ETH Denver is also a practical launchpad. It concentrates users, founders, and infrastructure teams in one place, which makes it easier to gather feedback and refine products quickly. For a project focused on onchain automation, that kind of real-world testing is valuable.

What CoinFello Is Building

CoinFello is positioned as a crypto-native AI agent that can use or automate smart contracts. Instead of forcing users to navigate multiple DApps, the product aims to let them issue prompts in a chat interface and complete tasks more naturally.

In practice, that could mean explaining a contract, batching actions, or helping a user move through a DeFi workflow with fewer manual steps. The goal is not to hide complexity forever, but to make Ethereum more accessible to people who would otherwise struggle with the current UX.

Jacob’s background at MetaMask shaped that thinking. He said the long-term mission has always been to make Ethereum safer and easier to understand, and AI agents now offer a new way to do that.

How AI Agents Are Changing DeFi

The biggest shift in this category is moving from bots that answer questions to agents that actually do things. That change became more realistic as model quality improved and as users became more comfortable with conversational interfaces. OpenAI’s rapid mainstream adoption helped normalize that behavior, and the broader AI market has accelerated expectations around what assistants can do. See OpenAI for the company that helped bring chat-based AI into the mainstream.

In crypto, that shift is especially important. DeFi is powerful, but it is still too complex for many users. An agent that can route actions, prepare transactions, and explain what is happening could make the experience far more usable.

That trend also aligns with the broader move toward better wallet UX and account abstraction. Products across the ecosystem are trying to reduce the number of decisions users must make before they can safely interact onchain.

Safety Is the Real Product Challenge

Jacob was direct about the biggest risk: if an AI agent misunderstands a prompt, it could trigger an irreversible onchain action. That is why safety is not a side feature in this category. It is the product.

CoinFello’s approach includes multiple verification layers, human control, and a multi-model architecture so that one model is not solely responsible for every decision. That kind of design reflects a broader industry lesson: the strongest AI x Web3 products in 2026 are permissioned first and broaden only after trust is earned.

Why the Market Is Better for This Now

Jacob argued that the current cycle is healthier than the 2022 environment, when scams and noise made it harder for real builders to stand out. Today, Ethereum has better technical foundations, more mature wallet experiences, and a stronger regulatory backdrop than in prior years.

That matters because agentic DeFi depends on trust. Users are more likely to adopt automation when the surrounding ecosystem already supports clearer signing, better simulation, and more predictable execution. The developer base also remains a major strength of Ethereum; widely cited research from Electric Capital continues to show how large and active the ecosystem is.

Community Ownership Still Matters

Beyond the product itself, Jacob returned to a bigger idea: the internet should be owned by its users, not controlled by a few giant platforms. He connected that belief to the early days of community ownership in crypto, when users could become real stakeholders in the protocols they helped build.

That vision is still relevant, but the mechanics are changing. Identity, anti-sybil systems, and AI-assisted verification may help projects reward real participation more accurately. In that sense, AI and crypto are not just converging technically; they are converging around a shared goal of better ownership.

Buffy: A Conference Agent With a Bigger Purpose

CoinFello also unveiled Buffy, an agent built for ETH Denver attendees. Buffy helps people find schedules, venues, vendors, and side events, making the conference easier to navigate. But it also serves another purpose: onboarding users into CoinFello’s private alpha.

That is a smart distribution strategy. Conference-specific agents are becoming a practical way to introduce users to new products because they solve an immediate problem while also demonstrating the value of conversational automation.

What CoinFello Signals for the Future

CoinFello is part of a larger shift in crypto: the move from interfaces that require expertise to agents that can carry out intent. The promise is simple but powerful. If the system is safe enough, users can do more onchain with less friction.

That could reshape DeFi onboarding, wallet design, and even how communities interact with protocols. The next major UX layer in Web3 may not be another dashboard. It may be an agent that understands what users want and helps them get there safely.
