Sui tests 40.6 million TPS in offchain tunnels settled to Sui mainnet at Basecamp
Sui said its offchain tunnels processed 40,614,180 transactions per second in an October 7 stress test at Sui Basecamp in Singapore, with closed tunnels settling to Sui mainnet.
Why it matters
The result sits inside Sui's push into agent-to-agent payments: Crypto.News points to an earlier partnership with Google's Agentic Payments Protocol, and Crypto News reports Sui is working with Alibaba Cloud on per-call stablecoin payments for AI agents drawing on that cloud footprint. Both aggregators say the number reflects offchain tunnel activity rather than mainnet throughput, and Crypto.News reports CertiK's detailed review of the test data is still outstanding.

Sui's release calls it the highest verified throughput settled to a blockchain, while two aggregators say it counts offchain tunnel activity rather than native mainnet throughput.

Key facts
Sui said its offchain tunnels processed 40,614,180 transactions per second in a live stress test at Sui Basecamp in Singapore on 7 October 2026, with closed tunnels settling to Sui mainnet.

Sui set a 20 million TPS target for the demonstration and said the result exceeded it.

More than 10,000 tunnels were opened on Sui mainnet during the test, covering payments, games and chat activity.

CertiK analyzed the test independently, though Crypto.News reports a detailed review of the test data is still pending and Crypto News reports the supporting proof is expected later.
Disputed figureReported by Brave New Coin
Crypto News and Crypto News (CryptoNews.net) both state the 40.6 million TPS figure counts offchain tunnel activity and does not represent native Sui mainnet capacity.

Crypto News reported $SUI fell 5.3% on the day Sui reached 40,614,180 TPS.

Crypto News reported Sui is teaming up with Alibaba Cloud so AI agents can pay for services per call with stablecoins, using Alibaba's cloud footprint across more than 90 availability zones.

What happened
Sui ran a live stress test on 7 October at Sui Basecamp in Singapore, where its programmable offchain tunnels processed 40,614,180 transactions per second and the closed tunnels settled to Sui mainnet. Cointelegraph and Crypto.News put the previous record, set during a 4 July livestream, at about 6.1 million TPS, while Sui's own release and the Chainwire copies carried by Brave New Coin and Finbold call it 6 million or over 6 million, and Crypto News gives 6.09 million. More than 10,000 tunnels were opened on mainnet during the test, with traffic spread across payments, games and chat, and Crypto News reported $SUI fell 5.3% on the day of the record. CertiK analyzed the event: Cointelegraph and Sui's release describe the work as independent analysis, Crypto.News says a detailed review of the test data is still pending, and Crypto News says CertiK confirmed the results but expects the relevant proof later. Both aggregators state the headline figure counts activity inside channels, which need one onchain transaction to open and one to close, rather than transactions executed on Sui mainnet. Mysten Labs co-founder and chief product officer Adeniyi Abiodun, who led the test, argued that human markets do not move fast enough to need either 6 million or 40 million transactions per second, while agents do.
