Key Takeaways
- Sui recorded 40.6 million transactions per second in an offchain stress test, more than six times its previous record.
- Samsung Wallet will introduce USDC transfers to 82 million eligible US Galaxy devices, with Sui as one of its blockchain partners.
- SUI price predictions remain divided, with analysts weighing growing adoption against weak market conditions and token supply risks.
Sui has delivered two major announcements in 48 hours, reporting a new blockchain throughput record and securing a place in Samsung Wallet’s upcoming stablecoin payment service.
On Oct. 7, Sui reported processing 40,614,180 transactions per second (TPS) during a live demonstration in Singapore, exceeding its previous record of 6.08 million TPS.
A day later, Samsung announced plans to introduce stablecoin functionality across 82 million eligible Galaxy devices in the US, with Sui among the supported blockchain infrastructure partners.
The developments could expand Sui’s role in digital payments, although neither guarantees an immediate increase in demand for its native SUI token.
Sui Breaks 40.6 Million TPS Record in Singapore
At Sui Basecamp, held alongside TOKEN2049, Mysten Labs co-founder Adeniyi Abiodun demonstrated the network’s ability to handle millions of transactions through programmable offchain channels called Sui tunnels.
The test exceeded its original 20 million TPS target and improved on July’s 6.08 million TPS result by approximately 6.7 times.
More than 10,000 tunnels were opened during the demonstration, supporting applications involving payments, gaming and AI agents.
However, the 40.6 million TPS figure measures transactions processed inside offchain tunnels, not transactions executed directly on Sui’s layer-1 blockchain.
These tunnels open and close through onchain transactions, with intermediate activity processed separately.
Security firm CertiK observed the demonstration, with a detailed independent audit report expected afterward.
Samsung Wallet Opens Sui Payments to 82 Million Galaxy Devices
On Oct. 8, Samsung confirmed that stablecoin transfers will launch in Samsung Wallet during the final week of October.
The service will initially support USDC, enabling eligible US Galaxy users to send funds to recipients in more than 60 countries, including transfers to supported bank accounts.
Sui and Solana are among the blockchain partners, while Bastion and Coinbase provide custody and payment infrastructure.
Sui says its network has processed more than $1 trillion in stablecoin transfer volume since August 2025.
Importantly, the 82 million figure represents eligible devices, not confirmed users. Samsung Wallet will initially support USDC rather than the SUI token.
SUI Price Prediction: Can the Token Recover Toward $1.40?
Despite the announcements, SUI struggled alongside the broader cryptocurrency market.
On Oct. 9, SUI traded around $1.07, falling approximately 4.92% over 24 hours, according to CoinMarketCap data.
The immediate price outlook depends on whether buyers can defend the $1 psychological level.
A sustained recovery above $1.15 could bring the $1.28 resistance area back into focus. A stronger breakout could reopen the path toward $1.40, a target previously highlighted by market analysts.
Conversely, a $1 loss could expose SUI to further selling, with approximately $0.88 identified as a lower support level.
Samsung’s integration offers potential long-term exposure, but gasless USDC transfers do not require users to hold SUI.
For investors, the next question is whether Sui can convert its technical achievements and new payment integrations into sustained network activity, rather than another short-lived market narrative.
