Grindery Launches Aventino, Permissionless Payments Layer for AI Agents

Grindery, a company backed by Yzi Labs, has unveiled Aventino, a permissionless payments layer designed for autonomous AI agents. This infrastructure is built on Ethereum and leverages the ERC4337 account abstraction protocol, enabling AI agents to operate independently, own wallets, make payments, interact with blockchain protocols, and establish tokenized communities across various platforms.

Aventino provides developers with the tools to build AI agents that can be distributed on any client or device, interact with protocols, issue their own tokens, and build communities around their agents. This infrastructure aims to empower developers to create platform-agnostic agents that can transact, govern, and evolve autonomously, much like mobile apps created a layer between users and the internet.

The core capabilities of Aventino include self-custodial wallets for AI agents, a creator-centric stack for publishing on various platforms, agent tokenization and monetization, and turnkey monetization options. These features allow AI agents to accept payments via traditional fiat methods and crypto, facilitating seamless transactions across platforms.

Grindery's journey began in 2022 within Yzi Labs' incubation program, where it developed a self-custodial crypto wallet with 3.5 million users. The success of this wallet led Grindery to expand into the market of empowering AI agents as autonomous economic actors. The launch of Aventino significantly extends the utility of Grindery's universal gas token, GX, which is now used for agent-to-agent transactions and deploying new agents via bonding curves.

Grindery is actively seeking partnerships with LLM platforms, messaging clients, wallet providers, no- and low-code platforms, and blockchain protocols with AI ambitions. The company has launched an idea forum to crowd-source ideas for customized AI agents and is onboarding developers from various fields. The next 4–8 weeks will be a pivotal phase as Grindery accelerates the development of Aventino, transitioning from private to public beta.

Grindery's mission is to build the permissionless payment layer for autonomous AI agents, enabling secure, interoperable transactions between web3-native AI agents across any chain or framework. By giving agents and humans financial autonomy through crypto-native wallets, Grindery is laying the foundation for a decentralized, agentic AI future.
