Ethereum News Today: DeFi's New Translator: CoinFello Automates Smart Contracts in Plain Language

HyperPlay Labs Inc. has unveiled CoinFello, a groundbreaking AI-driven application designed to democratize access to decentralized finance (DeFi) by automating complex smart contract interactions. Announced at DevConnect in Buenos Aires, Argentina, CoinFello aims to bridge the gap between mainstream users and blockchain technology by offering an intuitive chat interface that executes user intents in plain language. The tool, built on EigenCloud and Consensys' MetaMask Smart Accounts Kit, ensures users retain full custody of their assets while leveraging AI to simplify tasks like cross-chain transactions, gas fee management, and liquidity optimization.

The platform operates as a "self-sovereign" agent, meaning users delegate authority to CoinFello's AI without surrendering control over their funds. This model allows users to automate risk mitigation strategies, such as reallocating assets during market downturns. For instance, during October 2025's $1.7 billion in Ethereum-based liquidations, CoinFello's automation could have prevented losses by preemptively adjusting positions. Jacobc.eth, CoinFello's founder and former MetaMask operations lead, emphasized that the tool "minimizes risks while maximizing accessibility," positioning it as a catalyst for DeFi's mass adoption.

Underpinning CoinFello's security is EigenCloud, a verifiable cloud infrastructure developed by Eigen Labs. By integrating EigenLayer's restaking protocol, EigenCloud ensures AI-driven actions are cryptographically auditable, preventing manipulation by third parties. Sreeram Kannan, EigenCloud's CEO, noted the partnership's focus on delivering "deterministic and self-sovereign AI," allowing users to maintain control over both their data and the models they employ.

The application also leverages MetaMask's Smart Accounts Kit to streamline DeFi interactions. Users can issue commands like "Sell my meme coins to buy more ETH" or "Ensure my loan positions aren't liquidated during volatility," with CoinFello abstracting technical complexities such as token bridging and gas calculations. This functionality aligns with Consensys' vision of agentic AI, where according to Ryan McPeck, product lead at Consensys, "fine-grained permissions empower users to express exactly what they want on-chain."

CoinFello is currently in a private alpha phase, with a public release slated for Q1 2026. The tool's development team, veterans of MetaMask, gaming, and AI, aims to address key barriers to DeFi adoption, including fragmented user experiences and high entry costs. HyperPlay Labs, the project's parent company, also operates HyperPlay, a web3 gaming infrastructure platform.

While the launch marks a significant step for DeFi accessibility, challenges remain. Critics highlight the need for robust governance frameworks to ensure AI agents operate transparently and ethically. Nonetheless, CoinFello's integration of verifiable AI and user-centric design positions it as a potential game-changer in the evolving crypto landscape.
