CoinFello self-sovereign AI launched November 17, 2025 as what its team calls the first solution that is both fully self-sovereign and capable of supporting any smart contract interaction on any EVM chain. Built for MetaMask users, the agent lets people describe what they want in plain language and handles the underlying contract execution directly, without requiring a separate website-based dApp.
How CoinFello's Self-Sovereign AI Actually Works
Instead of navigating to individual protocol websites, users tell their CoinFello agent what they'd like to execute, such as "sell my meme coins to buy more ETH," and the agent interfaces with the relevant smart contracts directly on the user's behalf. Before anything executes, CoinFello presents the user with an overview of the planned smart contract interaction or automation for explicit approval, keeping the human in the loop rather than granting the AI unchecked authority over funds.
What "Self-Sovereign" Means Here
Self-sovereign in this context means the user, not CoinFello or any third party, retains full custody and control of both their wallet and the AI agent's actions. jacobc.eth, Founder and CEO of CoinFello and a previous Lead of Operations at MetaMask, said self-sovereign AI solves fundamental user experience problems for interacting with dApps and DeFi protocols, calling CoinFello the first time self-custodial DeFi can be made truly accessible to mainstream audiences.
The EigenCloud Partnership: Verifiable, Deterministic AI
CoinFello's approach is reinforced by a partnership with EigenCloud, aimed at ensuring the AI agent's outputs are verifiable, deterministic, and repeatable rather than subject to silent manipulation. Sreeram Kannan, Founder of EigenCloud and CEO of Eigen Labs, said the goal is to give users AI agents they fully control, running the exact model they signed up for, with reliable and repeatable outputs that protect against non-attributable manipulation in agents, a meaningful distinction from opaque, black-box AI trading tools.
A Concrete Use Case: Automated Liquidation Protection
One practical example CoinFello highlights is preventing liquidations during sudden market crashes. Users can ask their assistant to automatically reallocate funds in the event of a black swan scenario, referencing October 2025's market conditions, when more than $1.7 billion in liquidations occurred across Ethereum and EVM-compatible networks in a short window. An automated agent capable of reacting to those conditions faster than a manual trader could plausibly reduce losses in similar future events.
Abstracting Away Crypto's Core Complexity
CoinFello is designed to abstract away gas fee management, chain selection, token swapping, and cross-chain bridging, complexities that have historically kept mainstream users away from self-custodial DeFi. By translating a plain-language request into the correct multi-step on-chain execution, the agent removes much of the friction that pushes newcomers toward centralized, custodial platforms instead.
This kind of AI-driven contract automation complements the identity-and-rewards infrastructure seen in CARV's Cashie 2.0 x402 integration, both reflecting a broader 2025-2026 push toward AI agents that can autonomously act on-chain within defined guardrails.
Glossary
- Self-sovereign: A system design where the user retains full, exclusive control over their assets and agent actions, without a third party holding custody.
- Intent-based system: An interface where a user states a desired outcome in plain language rather than manually specifying each technical transaction step.
- Deterministic AI output: AI behavior that produces the same, verifiable result given the same inputs, rather than varying unpredictably between runs.
