Samsung Wallet to Bring USDC on Sui to 82 Million US Galaxy Devices

Samsung Wallet Integrates USDC on Sui

Sui closed its two-day Basecamp 2026 conference in Singapore with its clearest consumer payments play yet: Samsung Wallet is set to support USDC on Sui across 82 million Galaxy devices in the United States. The network laid out the deal in an official announcement posted on October 8, which describes USDC on Sui support built directly into Samsung Wallet, with gasless transfers and zero network fees. Users will not need to buy SUI first or hold a token balance for fees, because the design removes the cost step that has kept first-time stablecoin users out of digital dollars. In practice, a person sending digital dollars pays nothing at the point of transfer, which is what makes a consumer integration viable at scale. The crypto wallet preinstalled on Galaxy handsets therefore becomes a stablecoin rail for everyday transfers, the kind of distribution no crypto-native product has matched. International payments are the obvious use case: stablecoins already move value across borders faster than card networks, and embedding that flow in a default phone app removes the hurdle of a separate download, a seed phrase and a funded wallet address. Mysten Labs co-founder Adeniyi Abiodun framed the intent: “Our goal has long been to make money movement free and as easy as sending an email.” His firm builds the chain itself, so the tie runs from a consumer app down to the base protocol. For holders, the SUI price entered October after a rally of nearly 50% in September, and the deal hands that move a payments use case to grow into. Of everything announced at the event across payments, AI, Bitcoin finance and infrastructure, this is the piece built to reach past crypto traders and widen the Sui ecosystem to everyday users.

Verifiable Agent Arbiter and a 40.6M TPS Demo

A second Basecamp announcement targets the trust problem that has kept enterprises away from autonomous software. Google Cloud is working with Mysten Labs on the Verifiable Agent Arbiter, a tool built to prove whether an AI agent followed its instructions. The Singapore event framed this as Sui's bet on a future where software moves money on people's behalf and leaves an auditable record of doing so. Activity records stay private, while cryptographic proofs are written to Walrus, the decentralized data storage layer in the Sui stack, and to Sui itself, giving any counterparty a way to verify a decision without seeing the data behind it. That separation matters for compliance teams, who can check an outcome without receiving a copy of everything the agent touched. Mysten Labs CEO Evan Cheng said AI agents are starting to make decisions with financial and legal consequences, and that systems must guarantee they cannot exceed their authority. Kimberly Logan of the Walrus Foundation added that the arbiter lets companies and individuals prove, in a fully trustless way, that their agents acted within the bounds of their authority, supporting agentic workflows across trust boundaries and industries. It sits squarely inside the DeFAI push, where autonomous finance assumes an AI crypto wallet signing transactions without a human at the keyboard. Throughput was the third headline: Sui posted a figure of 40.6 million transactions per second from a live stress test, run through programmable offchain tunnels that settle back to its blockchain, as a roundup of everything announced at Basecamp confirms. One caveat: the figure counts flow inside those tunnels, not 40 million transactions run directly on mainnet, and the architecture keeps bulk activity off the base chain while still anchoring settlement on it. Protocol work continues on a separate track too: Mysten Labs has processed the first quantum-resistant Sui transaction under Protocol version 139.

Samsung offers reach: 82 million devices is distribution the industry cannot buy, yet gasless USDC transfers do not automatically lift demand for the native token, since moving the stablecoin requires no SUI at all. Google Cloud aims higher up the stack, at institutions: banks building agentic workflows could use Sui and Walrus to verify automated financial decisions and meet compliance requirements, and real deployments will decide what that is worth. The Sui Foundation has backed the data side before, committing $30 million to the DATA Network's migration to Sui, and custody rails are widening in parallel through Bitget's expansion of off-exchange settlement routes for assets like SUI. The test into 2027 is whether these openings convert into measurable network usage, and our Sui technical analysis tracks where the token sits against support and resistance.
