Metropolis protocol to enable AI agents to create custom blockchain networks

A new protocol called Metropolis is poised to revolutionize the integration of artificial intelligence and blockchain technology.

Developed by Saga in collaboration with ai16z, Virtuals, and Wayfinder, Metropolis enables AI agents to build and operate specialized, interconnected blockchains known as “chainlets.”

The protocol, set to launch in the spring, aims to create environments where AI agents can collaborate and innovate seamlessly.

“Metropolis is specifically designed for AI agents,” said Saga CEO Rebecca Liao. “It allows AI agents from different protocols to communicate on the same chain and establish their own blockchain networks within Saga’s infrastructure.”

Ai16z’s ElizaOS will provide advanced AI functionalities for cross-chain interactions, Virtuals’ Butler Agent offers hosted wallets and pre-coded functions, and Wayfinder’s multi-chain AI framework supports smart contract deployment and navigation. Together, they create a unified ecosystem for unprecedented collaboration among AI agents.

Blockchains offer unique advantages for AI, including decentralized and tamper-resistant environments, smart contracts for autonomous execution, and the ability to transact using crypto. 

However, integrating these technologies is not without challenges. Autonomous AI agents could potentially compromise decentralization, exploit security vulnerabilities, or even defy developers’ intentions. Liao noted instances where AI agents have shown unexpected autonomy, such as rebelling against parent protocols or users’ instructions.

Despite these risks, the blockchain-AI market is thriving, with a total market cap of US$29.2 billion for AI agent-related tokens and US$77.6 billion for the broader AI crypto sector. 

Metropolis makes use of Saga’s chainlets—dedicated, customizable layer-1 blockchains that operate independently. Chainlets ensure predictable fees and consistent performance by isolating operations from other applications. Developers can also deploy multiple chainlets to optimize scalability and efficiency.

“When you deploy on Saga, you’re getting your own dedicated L1 blockchain rather than just renting space on a shared chain like Ethereum,” Liao explained. This setup allows developers to design flexible, gasless environments tailored to their applications.

Liao sees Metropolis as a transformative platform that channels the ideals of decentralization and individuality. “Metropolis breaks away from sameness, enabling unique, self-directed applications,” she said.

As AI agents continue to evolve, Metropolis could become a cornerstone for blockchain innovation, blending the potential of both technologies into a platform designed for collaboration and growth.
