Fort Worth, Texas, March 30th, 2026, Chainwire
CoinFello, the first self-sovereign AI agent for using or automating any onchain action, today announced its public launch at EthCC in Cannes. CoinFello provides users access to a conversational interface that enables them to research, execute, and automate onchain transactions using natural language while maintaining full custody of their wallets and private keys.
Previously available only in private alpha through waitlist access, CoinFello is now open to the public through its web application. The platform enables users to send tokens, swap assets, bridge across chains, and interact directly with decentralized protocols through a chat-based interface that translates plain language instructions into blockchain transactions.
The launch arrives as interest grows around the convergence of DeFi and autonomous AI agents. Despite hundreds of billions of dollars in total value locked across DeFi protocols, active DeFi participation remains limited compared with the global population of crypto holders. The complexity of tools and security concerns when interacting with decentralized applications has been a barrier to entry, with many owning crypto assets sitting idle in their wallets, having never staked, bridged, or earned yield. This is not due to a lack of demand, but because they don’t know where to start and fear making irreversible, costly mistakes.
“Today’s launch marks a shift from passive crypto ownership to active participation,” said MinChi Park, Co-founder and COO of CoinFello. “By combining self-custody with a natural language interface, we’re enabling millions of users to interact with DeFi in a way that is both accessible and secure, without compromising control.”
CoinFello’s architecture is designed to prioritize security and user control. Rather than granting AI agents direct access to wallets, the platform uses a delegation model that allows users to assign limited spending permissions with configurable timeframes and token limits. Private keys remain on the user’s device, and on macOS systems, where they are secured at the hardware level using the device’s Secure Enclave hardware.
Users can connect an existing MetaMask or other EVM-compatible wallet through smart account delegations. For those who connect an EOA existing wallet, CoinFello also creates a smart account that is tied to the user’s existing EOA wallet for use in Automations. Transactions are displayed in human-readable terms before execution, allowing users to review and approve actions before they occur.
CoinFello also introduces integrations designed for the emerging ecosystem of personal AI agents. Through its agent skill, which was recently launched for OpenClaw but is also available for other agents (Claude Code, Kiro, Hermes, etc.), users can equip their personal AI agents to execute onchain transactions using CoinFello as an execution layer. Agents can request delegated permissions from users and perform operations such as sending tokens, swapping assets, or staking, while operating within predefined limits set by the user and without handing over their private key.
At EthCC, the company will present its technology to Ethereum developers and the broader Web3 ecosystem. The conference is one of the largest Ethereum-focused gatherings globally, bringing together builders, investors, and media professionals who cover the intersection of blockchain infrastructure and emerging technologies.
With its public release, CoinFello introduces features including natural language transaction execution, delegation-based permissions, cross-chain routing, and automation capabilities such as recurring transactions. The platform also includes a notification system that alerts users to executed automations, potential risks, or new opportunities across supported networks.
The launch marks the first phase of CoinFello’s roadmap toward progressively decentralized infrastructure designed to support both consumer applications and developer integrations in the emerging AI agent ecosystem.
About CoinFello
CoinFello is an AI agent for researching, executing, and automating onchain actions. Using plain language, users can send, swap, bridge, stake, and automate crypto across EVM-compatible networks, while keeping full custody of their wallets and private keys throughout. CoinFello uses a delegation model that gives agents only the permissions users choose to grant.
