Sui said Mysten Labs has partnered with Google Cloud to launch Verifiable Agent Arbiter (VAA), a proof layer for enterprises to verify whether AI agent actions were carried out within authorized limits. According to Odaily, VAA anchors related proofs on Sui and WalrusProtocol.

The system combines an agent’s authorization scope, actual actions, and final results, while keeping sensitive information such as prompts, model outputs, tool calls, and policy decisions private. It stores the data in Google Cloud Storage controlled by customers.

VAA also supports dispute replay, event reconstruction, and verifiable agent transactions through Sui Agent Pay and x402. It can help enterprises meet regulatory requirements, including the European Union AI Act.
