Overview
- Sui recorded a peak of 40,614,180 transactions per second in a live demo at Basecamp in Singapore on Wednesday, Oct. 7, 2026, using more than 10,000 programmable off‑chain tunnels.
- Tunnels are state channels that require an on‑chain transaction to open and another to close while intermediate messages run gaslessly off‑chain and are cosigned so final states can be verified on Sui mainnet.
- CertiK verified the live throughput figure during the event and will publish a detailed audit of proofs, execution logs, and supporting data in the coming days to explain methodology and evidence.
- The test emphasizes trade‑offs: tunnels cut intermediate gas costs and raise throughput for AI‑driven agents, but the 40.6M TPS headline reflects off‑chain activity that does not equal individual base‑layer writes.
- The demonstration builds on Sui’s July tunnel test and recent product moves such as the USDsui stablecoin and a partnership on Google’s Agentic Payments Protocol that aim to enable automated micro‑payments and agentic commerce.
