Sei Development Foundation has announced a new integration with TMO Labs aimed at bringing blockchain technology into South Korea’s mainstream payment and financial infrastructure. The collaboration will integrate TMO Labs’ services with the Sei Network, positioning Sei as the underlying blockchain layer supporting TMO Wallet and its expanding real-world financial applications.
The initiative focuses on combining blockchain-based digital assets with existing payment, rewards, and consumer finance systems already widely used throughout Korea. Through the integration, users will be able to manage digital assets, reward points, and prepaid balances within a unified platform designed for daily financial activities.
TMO Labs develops payment infrastructure solutions connecting blockchain technology with real-world financial services. Its primary product, TMO Wallet, functions as an all-in-one digital wallet allowing users to access blockchain assets alongside traditional rewards and payment balances for transportation, retail purchases, and other consumer transactions.
TMO Labs will integrate Sei Network as the core blockchain infrastructure behind TMO Wallet to support real-world payments, rewards, and digital finance services in Korea.
Sei Chosen for High-Speed Financial Transactions
The Sei Development Foundation, an independent US-based nonprofit organization, supports the growth of open-source blockchain protocols such as Sei. The network was developed to combine Ethereum’s ecosystem advantages with transaction speeds commonly associated with high-performance blockchain infrastructures.
According to the announcement, Sei was selected because of its ability to handle real-time payment environments requiring fast transaction processing and high throughput. The blockchain reportedly offers sub-second finality and is designed to support large-scale financial activity without sacrificing transaction reliability or user experience.
Industry analysts noted that speed and scalability remain critical requirements for blockchain adoption within consumer payment systems. Payment platforms serving transportation networks, retail purchases, and loyalty systems require infrastructure capable of processing large transaction volumes with minimal delays.
TMO Labs brings experience in several areas of consumer finance, including transit payments, mobile payment systems, loyalty programs, and digital financial services. The company’s existing infrastructure and partnerships are expected to support broader blockchain integration into Korea’s established payment ecosystem.
TMO Wallet Expands Real-World Utility
TMO Wallet is already integrated with DaemDaem, a transportation recharge and lifestyle rewards platform widely used in Korea. The wallet is also designed to connect with several major domestic payment and rewards systems, including Naver Pay, Payco, Happy Point, L.POINT, TMONEY, and EZL.
These combined payment and loyalty ecosystems collectively represent millions of consumer touchpoints across South Korea’s retail, transportation, and rewards markets. Through the Sei integration, users will reportedly gain the ability to store Sei-based digital assets, including stablecoins, directly within TMO Wallet and connect them to existing payment and loyalty systems.
The companies indicated that the integration aims to create a more streamlined financial experience where blockchain assets, reward points, and conventional payment balances can all be managed within a single application. Users are expected to apply these assets across a variety of daily activities, including online shopping, retail transactions, and transportation top-ups.
The integration will allow users to combine blockchain assets, reward points, and payment balances within a single wallet connected to Korea’s major consumer payment ecosystems.

Industry observers suggested that projects linking blockchain infrastructure with existing consumer payment networks may help accelerate mainstream adoption by reducing friction for users unfamiliar with digital assets.
Broader Push Toward Real-World Blockchain Adoption
The collaboration also reflects a wider effort within the blockchain industry to connect decentralized financial infrastructure with practical consumer use cases. Rather than focusing solely on speculative trading applications, companies are increasingly prioritizing payment systems and financial tools tied to everyday economic activity.
TMO Labs founder Jin Kim stated that the partnership represents an important step toward integrating blockchain technology into ordinary consumer spending and financial behavior in Korea. He indicated that combining TMO Labs’ payment infrastructure with Sei’s blockchain capabilities could help create a more practical and user-focused digital finance experience.
Meanwhile, Justin Barlow, Executive Director of the Sei Development Foundation, explained that TMO Labs maintains strong connections to Korea’s payment, transit, and rewards infrastructure. He suggested that the integration could become one of the clearest examples of blockchain technology being deployed in large-scale real-world consumer environments.
The partnership reflects a broader industry trend toward integrating blockchain technology directly into mainstream consumer finance and payment infrastructure.
