Sui, Remi Technology Launch Stablecoin Payments System for Financial Institutions

Sui is launching a system that will allow financial institutions to use stablecoins for payments and settlement within existing banking workflows.

Remi Technology, a global cross-border payments and settlement infrastructure company, is launching a stablecoin payments system for financial institutions integrated with Sui, the Sui Foundation said on June 16. The system is designed to let banks use stablecoins within account-based banking operations without relying on overseas custodians or separate crypto payment networks.

"Institutions do not need stablecoins that bypass them. They need stablecoins that operate within their own systems," Sui said. The effort is meant to position stablecoins not as an alternative outside traditional finance, but as a tool banks and licensed financial institutions can use for actual payment and settlement operations.

The system supports transfers of EUB and USB, electronic money tokens issued by Bison Bank. The tokens were designed as e-money tokens compliant with the European Union's Markets in Crypto-Assets regulation, or MiCA, and can be used through Bison Bank and participating partner banks.

The service will be available in Europe, Asia, Latin America, the Middle East and North America. The Sui Foundation said it provides licensed financial institutions with a route to handle cross-border remittances faster and with greater transparency through regulated banking relationships.

Remi's payment network is focused on bringing stablecoin-based clearing and settlement into existing banking operations. Bison Bank and partner-bank clients will be able to send and receive Sui-based EUB and USB through the bank accounts they already use for daily transactions, the foundation said. That eliminates the need for separate overseas custodians or standalone crypto payment rails.

The foundation said Sui's object-centric architecture and programmable infrastructure are suited to compliance-focused payment systems. EUB and USB support real-time branch-to-branch settlement at predictable cost.

Compliance is a central feature of the system. Remi's network was designed to meet MiCA, Financial Action Task Force standards and Basel Committee requirements. Its smart contracts incorporate risk controls and the FATF Travel Rule into each transaction, while its messaging and interfaces are configured to be compatible with SWIFT.

Bison Bank is a financial institution authorized and supervised by the European Central Bank. The Sui Foundation described EUB and USB as the first regulated stablecoins on Sui with bank backing and a financial reporting treatment structure.

"Institutions moving funds across borders need infrastructure built to institutional standards," Remi Chief Executive Officer Sam Su said. "Remi was designed to meet the regulatory requirements of major financial institutions, and Sui provides the blockchain capabilities to support that."

Stablecoin transfer volume on Sui has exceeded $1 trillion since August 2025, according to the Sui Foundation. It said the Remi integration will expand Sui's role in global payments infrastructure by adding regulated, bank-grade clearing and settlement capabilities.
