$SUI conducted a stress test at Sui Basecamp in Singapore, with Sui tunnels processing more than 40 million transactions per second. The official announcement was published on the evening of October 7, Beijing time.

SUI is a public blockchain focused on payments and on-chain applications. Tunnels are its off-chain channels: transactions are processed in the channel first, then settled on the mainnet when it is closed.

Sui says this system is designed for AI agents. Agents can interact frequently without putting every transaction on-chain; they only need to open and close a channel.

CertiK served as the independent auditor for this test. The report will be published in the coming days.
