Line Next said Aug. 21 that it co-hosted a seminar with Payletter in Seoul's Yeoksam-dong on Aug. 12 under the theme "The Future of the Global Payments Ecosystem." The event covered stablecoin payment adoption structures, global settlement procedures and market prospects.
About 50 representatives from companies involved in overseas payments attended the seminar. It was organized as more businesses consider adopting stablecoin payments and seek to discuss implementation structures and regulatory requirements.
In a presentation session, Kim Dong-young, a team leader at Line Next, introduced changes in the stablecoin payments market and Unifi Pay's strategy. He said the share of USDT usage for holding, payments and remittances increased to 55% in 2025 from 35% in 2022. He also projected that local stablecoin payment markets linked to national currencies would emerge as major Asian countries refine their regulatory frameworks.
According to Line Next, Unifi Pay has secured more than 100 wallet payment integration cases. In services including game B2C and C2C, stablecoin payments accounted for more than 30% compared with cash. Unifi Pay is a stablecoin-based wallet and payments infrastructure service developed by Line Next.
"If merchants have to directly hold and manage stablecoins, there is no reason for them to consider adoption," Kim said. "Unifi Pay is aimed at letting users pay with stablecoins while merchants keep their existing settlement structure and simply add another payment option."
In a separate presentation, Payletter outlined country-specific regulatory requirements companies need to check when introducing overseas payments. Payletter supports more than 100 local payment methods, including global cards and PayPal, and provides services in more than 20 countries. Its total payment volume last year was 2.4 trillion won ($1.74 billion), and its cumulative merchant count reached 20,000.
Choi Yoon-je, a director in Payletter's overseas business team, said companies need to review anti-money laundering obligations under the Act on Reporting and Using Specified Financial Transaction Information, as well as merchant screening requirements set by global card companies, when introducing overseas payments. Because separate regulatory requirements apply depending on the country and industry, companies need a market-by-market response, he added.
Ryan Yoon, a director at Tiger Research, said stablecoins could eventually complement existing financial infrastructure in payments and settlement. Fiat currency-based payment systems will not disappear immediately, but stablecoin settlement could establish itself as a separate channel, allowing merchants to choose the settlement method that best suits their needs.
Line Next said it plans to gradually expand support beyond USDT and JPYC to stablecoins linked to major Asian currencies. Kim said the company aims to build payment infrastructure that allows merchants to reach users across Asia through a single integration, without having to respond separately in each market.
