CoinFello unveiled its open-source OpenClaw skill in partnership with MetaMask, enabling AI agents to execute on-chain transactions without ever accessing a user’s private key. The OpenClaw framework centers on delegated permissions, allowing wallet owners to grant narrow, task-specific authorization rather than blanket access. Built on Ethereum standards ERC-4337 smart accounts and ERC-7710 delegations, it lets wallets issue limited, programmable instructions to an AI agent while keeping the actual signing key on the user’s device.
CoinFello’s agents, dubbed Moltbots, serve as the user-side layer. A Moltbot receives a natural-language instruction and passes it to CoinFello as a delegated task. Before any action is executed, an evaluation layer reviews the transaction for validity, and only then does it go on-chain.
“If we want agents to participate meaningfully in the on-chain economy, we need a security model that is better than handing an autonomous system a private key,” said Brett Cleary, CoinFello’s CTO. “The CoinFello Skill introduces hardware-isolated keys and fine-grained delegations, giving AI agents a secure way to execute transactions while helping bootstrap on-chain capabilities for the broader agent ecosystem.”
The capabilities are broad. Using natural-language prompts, Moltbots running the OpenClaw skill can swap ERC-20 tokens, bridge funds across networks, interact with NFTs, stake assets, lend, rebalance portfolios automatically, and execute multi-step trading strategies.
That range matters as it positions CoinFello not as a single-function tool but as a programmable financial agent capable of managing an active on-chain portfolio, all without requiring technical knowledge from the user. The skill is built on the Agent Skills specification and is compatible with Claude Code environments. It is released under the MIT licence, meaning developers can freely modify, deploy, and build on it.
A growing ecosystem. The timing reflects real momentum in the OpenClaw developer ecosystem. In the past two months alone, the OpenClaw GitHub repository has surpassed 150,000 stars and 22,000 forks, strong signals of developer adoption. npm downloads exceeded 416,000 in the past 30 days, a metric that tracks how often developers are actively pulling the code into their own projects. The broader trend is clear: developers are increasingly experimenting with autonomous software agents capable of interacting with decentralised networks. What remains is a security architecture credible enough for real financial use. CoinFello’s OpenClaw skill aims to build that foundation, not by limiting AI agents, but by precisely defining their reach.
