Sei Network Enters South Korea Payments Via Tmo Labs Integration

@SeiNetwork is pushing deeper into real-world finance with a significant new integration in South Korea. The Sei Development Foundation announced that TMO Labs, a Web3 fintech company, will integrate with Sei Network, a high-performance Layer-1 blockchain, with the aim of bringing blockchain technology into Korea's everyday payments and financial infrastructure.

As part of the integration, TMO Labs will use Sei as the core blockchain behind TMO Wallet, focusing on expanding real-world use cases across consumer payments, rewards, and digital finance in Korea.

Why Sei?

Sei was chosen for its ability to handle real-time payment environments. With sub-second finality and high throughput, it supports large-scale, high-frequency transactions without sacrificing the speed and reliability that modern payment systems demand.

TMO Labs is a Korean payment infrastructure company with deep experience in transit payments, mobile payments, loyalty systems, and consumer financial services. Its flagship product, TMO Wallet, is already connected to DaemDaem, a widely used transportation top-up and lifestyle rewards app in Korea, giving it access to a large existing user base.

Tens of Millions of Payment Touchpoints

TMO Wallet is designed to connect with major domestic payment and loyalty ecosystems, including Naver Pay, Payco, Happy Point, L.POINT, and transportation-linked payment rails such as TMONEY and EZL. Even accounting for overlapping users, these platforms represent tens of millions of consumer touchpoints across Korea's payments landscape.

Through the integration, users will be able to hold Sei-based digital assets, including stablecoins, within the wallet and link those assets to TMO Labs' point and payment infrastructure for everyday transactions. The scope of the deal spans blockchain-based payment and rewards infrastructure, Korean loyalty service integrations, transportation and mobility use cases, and consumer-facing Web3 financial services.

Jin Kim, Founder of TMO Labs, called it "an important step toward making blockchain technology a natural part of everyday financial activity and consumer spending in Korea," with the goal of delivering "a practical digital finance experience centered on real usage."

The Korea deal is not Sei's only recent push into mass-market payments. Sei and Xiaomi previously announced a partnership to integrate a pre-installed crypto wallet on new Xiaomi devices sold outside China and the US, targeting 168 million annual users — underscoring the network's broader strategy of anchoring $SEI to real-world financial infrastructure at scale.
