Mysten Labs launches Sui Seal MPC to let AI agents transact without holding keys. * June 27, 2026 * Posted by: admin * Category: BitCoin, Blockchain, Cryptocurrency, Investments Mysten Labs has launched Sui Seal MPC on the Sui mainnet, according to the validated writing pack, introducing infrastructure designed to let autonomous AI agents execute on-chain transactions without directly holding or controlling private keys. The system uses multi-party computation, distributed key shares and Move smart-contract policies to reduce one of the biggest risks in agentic crypto applications: giving software agents spending power without handing them a single exposed key. Tl;dr. * Mysten Labs launched Sui Seal MPC on the Sui mainnet in June 2026. * The system is designed to let AI agents transact on-chain without holding private keys. * Key shares are distributed across independent nodes to reduce single points of failure. * Move smart contracts can enforce rules such as spending caps and allowed counterparties. * The system also supports hidden bids for AI-driven trading use cases. Solving the agent key problem. AI agents can only become useful in on-chain markets if they can take actions. But giving an autonomous system full access to a private key is risky. If the agent is compromised, misconfigured or manipulated, funds can move instantly and irreversibly. Sui Seal MPC is positioned as an answer to that problem. Rather than letting an agent hold a complete private key, the MPC system distributes key shares across independent nodes. No single node controls the full signing authority. Transactions can be executed only when the required computation and policy conditions are met, reducing the danger of a single exposed credential. Move policies add guardrails. The validation pack states that Move smart contracts can enforce customizable spending and compliance policies. Examples include daily caps, allowed counterparties and other rule-based constraints. That part is important because secure signing alone does not solve the entire problem. Agents also need boundaries around what they are allowed to do. For enterprise or trading use cases, those guardrails could matter as much as the cryptography. A company may want an AI agent to pay approved vendors, rebalance a narrow set of assets or participate in a marketplace, but not drain a treasury or interact with unknown contracts. Policy enforcement gives developers a way to define those limits. Hidden bids and on-chain markets. Sui Seal MPC also supports "hidden bids" for AI-driven trading, according to the validated pack. In that model, bids can remain encrypted until a synchronized reveal. That could be useful in markets where early exposure of bids creates front-running or coordination risks. The feature is still technical and should not be overhyped. It does not mean AI agents are suddenly ready to dominate decentralized markets. But it does show how cryptographic infrastructure is being built around the assumption that autonomous software will eventually need to participate in on-chain commerce. Why it matters for Sui. For Sui, Seal MPC gives the network a clearer position in the emerging "agentic web" narrative. Many chains are talking about AI agents, but the practical question is how those agents safely hold authority, sign transactions and follow rules. Sui's pitch is that Move-based policy controls and MPC signing can provide that foundation. The next test will be adoption. Developers will need to build real applications around Sui Seal MPC, and users will need to trust that agent permissions are understandable and enforceable. For now, the launch gives the Sui ecosystem a concrete infrastructure milestone at the intersection of AI, cryptography and on-chain markets.

Sui blockchain registers $65 billion in stablecoin volume following major fee removal protocol. The high-performance blockchain engineered for fast and cheap transactions has garnered attention, reaching large stablecoin volumes after making stablecoin movements fee-free at the protocol level. According to Certik, the network has settled nearly $65 billion in stablecoins since June 10. Key takeaways. * Mysten Labs cut Sui fees, driving $65B volumes since June 10 after making stablecoins transactions free. * Certik noted Sui hit $2.27T in volume since early 2024, focusing on B2B markets and retail use. * Adeniyi Abiodun states Sui aims to increase market adoption as devnet tests private transactions. Sui attracts attention with gasless stablecoin transactions, reaches $65 billion in settlements. Sui, a high-performance blockchain, made a big bet to bring stablecoin volume to its network, and it seems it is paying off. In May, Mysten Labs announced that it was rolling out a protocol-level change for gasless stablecoins transactions in Sui, meaning that users would not need to pay fees in the native token, SUI, to move them on-chain. This has increased the volume of stablecoins being transacted on Sui, as users have been flocking to the network to take advantage of this new feature, which was primarily focused on simplifying B2B payments and microtransactions but also affects retail usage. Certik, a blockchain security firm, revealed that Sui's blockchain had processed nearly $65 billion in stablecoin transactions since June 10 without paying fees. Also, the network has registered over $2.27T in stablecoin volume since early 2024. Adeniyi Abiodun, co-founder and CPO of Mysten Labs, anticipated the effect of this move at its launch, calling it a game-changer and warning that it might render traditional settlement channels obsolete. Abiodun recently reinforced the relevance of this feature, stressing that gasless stablecoin transactions "remove HUGE overhead that blocks adoption." "Even at 1/1000th of a cent, gas forces you to hold reserves, build payment logic, monitor balances, and account for a second asset just to move the first. For any service provider, that overhead is infrastructure, headcount, and audit scope," he assessed. At a recent interview, he revealed that Sui's goal was to replace SWIFT and traditional rails by offering high scalability and privacy as key advantages. Sui is now testing private transactions in its devnet with a proposal that offers controlled visibility for compliance and auditability while maintaining transfer amounts and balances confidential. Sui aims to introduce this feature in the near future. Crypto Fear and greed index. Extreme Fear Yesterday Extreme Fear Last Week Extreme Fear Last Month Fear How do you feel about the market today?

The collaboration between Merkle Science and Mysten Labs addresses the pressing challenge of transfer confidentiality within the blockchain network. In this respect, the move unveils Confidential Transfers to maintain privacy of transaction amounts while also enabling compliance. Thus, with the merger of compliance and confidentiality, the initiative deals with the most noteworthy dilemma that the blockchain technology is facing in the institutional sector. Confidential Transfers are set to permit consumers to maintain their privacy while making no compromise on the inclusion of diverse compliance signals. For this purpose, Merkle Science is delving into the working of monitoring, investigations, and risk scoring in this framework. This ensures that institutions and regulators get substantial insights while not requiring complete public visibility in the case of financial activity. The respective approach highlights a wider market trend of leveraging privacy-first technologies that also meet the demands of auditors and regulators. With the integration of compliance into confidential workstreams, the development delivers a pathway for wider blockchain adoption across sectors where accountability and privacy must coexist. Additionally, it paves the way for new benchmarks in broader financial infrastructure with priority given to both institutional trust and user protection. Fortifying institutional trust in blockchain and wider adoption. According to Merkle Science's Vice President of Business Solutions, Dr. Justus Delp, financial information needs to remain private without any exposure to personal wealth or trade activity. This perspective denotes Confidential Transfers' ethical foundation, taking into account enforceability of compliance mechanisms and privacy preservation. Ultimately, this launch emerges as a landmark development to further evolve the blockchain technology toward compliant, private, and secure financial primitives.
