- On June 19, Sui announced the launch of Seal MPC on the mainnet, which is a platform based on Multi-Party Computation (MPC) that allows AI agents to access information.
- Private information remains hidden while access is controlled by the chain.
- The launch focuses on the fast-growing field of AI, where autonomous assistants are expected to drive billions in business.
June 19, Sui Network announced the launch of Seal Multi-Party Computation (Seal MPC) on the mainnet, which is a major step in creating a secure infrastructure for AI agents.
The seal is described as an interface of data, AI, and digital assets that enables encryption and access control.
Using MPC technology, the system uses distributed encryption techniques to access multiple independent parties, ensuring that no single party, including an AI agent, can move money or access encrypted data.
The first mainnet MPC board works with 5-of-8 starting points, including 8 operating nodes. Developers now have the option of deploying large independent servers, MPC boards, or hybrid configurations, allowing for more reliable and reliable models. The platform also supports natural language rules through Move’s smart contracts, enabling users to define AI payment policies such as daily caps or peer restrictions. This implementation builds on the main stable server that was launched on the Sui testnet in March 2026.
How Seal MPC Works
The seal allows for sensitive information, such as AI types, preferences, or the agent’s memory, to remain hidden or in storage systems like Walrus. At the same time, the right to access this data is controlled by smart contracts on Sui blockchain. Developers can implement these values using the Move programming language, and data interpretation can only be done if possible rules are met.
With the addition of Seal MPC, reliability is also managed. Instead of relying on a single key server, the task force collectively secures key sessions using cryptography and distributed key generation.
In the initial planning, the committee uses 5 of the 8 installations, including participants such as Mysten Labs and Triton One. No single group holds the entire key. When a request is made, it goes through an aggregator that aggregates partial responses from committee members, and the client extracts the data from there. Master keys are not available in one place.
There are many advantages to this method. Committee members can be changed without requiring re-encryption, meaning that public keys and policies can be maintained even if the committee changes. Developers have flexible options, as they can mix independent key servers, MPC boards, or hybrid setups with the same software development tools. The system integrates with the Sui AI stack and doubles with Walrus to keep it stable. This supports use cases such as agent memory, flexible wallets, and agency marketing.
AI Agent Salary Growth
The launch of Seal MPC comes at a time of strong growth in the so-called agency economy. AI assistants are going beyond just providing advice and recommendations. They are becoming independent who conduct events, manage assets, and coordinate financial activities on their own.
According to McKinsey resultsthe global retail market could reach between $3 and $5 trillion by the year 2030. In the United States alone, the consumer sector could generate over $1 trillion in fixed income.
The agent’s fees The market is also expected to grow significantly, with forecasts showing that it can increase to $93 billion by 2032. Estimates of the broad AI agent market in 2026 range from $8 billion to 12, with strong double annual growth rates expected in 2030. In the crypto sector, the AI agent must be built to be able to manage small purchases, and exchanges and money purchases, .
