ZEC $1,326 Sui tunnels hit 40.6M TPS in live AI agent test
Sui said its offchain tunnels peaked at 40,614,180 TPS in a Singapore demonstration, topping a July test, with CertiK still reviewing the data.
Key takeaways
- The peak was 40.6M. Sui reported a peak of 40,614,180 TPS inside its offchain tunnels during the Oct. 7 demonstration.
- July reached about 6.1M. A similar July test produced about 6.1 million TPS, and the event target was 20 million TPS.
- The audit is pending. CertiK acted as an independent auditor and is still reviewing the data, with a report expected in the coming days.
What happened
Sui said its programmable offchain tunnels processed a peak of 40,614,180 transactions per second in a live stress test on Oct. 7. The demonstration took place at Sui Basecamp in Singapore. The result was above the about 6.1 million TPS that a similar July test produced, and above a 20 million TPS target set for the event.
More than 10,000 tunnels were opened on Sui mainnet for the test, and the activity covered payments, games and chat applications. A tunnel is a programmable channel. It takes one onchain transaction to open and another to close, while the repeated interactions in between run offchain.
Why it matters
The test is aimed at machine-driven activity rather than human payments. Sui says the tunnels are designed for high-frequency activity, including interactions between AI agents, so that not every transaction has to be processed onchain. Adeniyi Abiodun, co-founder and chief product officer at Mysten Labs, said: "Sui is built for the moment when millions of AI agents are transacting every day."
Abiodun framed the capacity in terms of agents: "No market in the world needs 6 million transactions per second, let alone 40 million: people just don't move that fast. Agents do."
The figure comes from Sui and has not been independently confirmed yet. CertiK acted as an independent auditor during the demonstration and is still reviewing the test data, with a report expected in the coming days.
What the data shows
Reported peak: 40,614,180 TPS inside offchain tunnels. Comparison point: about 6.1 million TPS in July, using the same type of channel.
Tunnels opened on mainnet: more than 10,000. Target for the event: 20 million TPS, which the foundation said the result exceeded.
Settlement design: the foundation said closed tunnels are cosigned by participants and can be checked onchain.
Background
Sui introduced the tunnels in the July demonstration and calls them programmable, so builders can use them for applications beyond simple transfers.
In September 2025, Sui became a launch partner for Google's Agentic Payments Protocol, which is an open-source standard that lets AI agents pay on a user's behalf.
What is still unclear
- The 40.6 million TPS figure describes throughput inside the tunnels, not transactions recorded on the Sui blockchain itself.
- CertiK's review is pending, so the number has not been independently confirmed.
- The reports do not give a year for the July test used as the comparison.
Questions readers ask
What does 40.6 million TPS on Sui measure?
It measures activity inside Sui's offchain tunnels, which are programmable channels that settle to the Sui blockchain when they close. Transactions between opening and closing stay offchain.
How many tunnels did Sui open for the test?
More than 10,000 tunnels were opened on Sui mainnet during the demonstration, and they carried payments, games and chat activity.
Did CertiK verify the Sui TPS result?
Not yet. CertiK served as an independent auditor during the demonstration and is reviewing the test data, with a report expected in the coming days.
How does the October test compare with Sui's July test?
Sui said the October demonstration peaked at 40,614,180 TPS, while the July test reached about 6.1 million TPS.
