Krungsri Bank is expanding its digital financial innovation by testing THBC in the Programmable Payment project under the Enhanced Regulatory Sandbox. It is among the first service providers in Thailand to test Programmable Payments in a real-world setting.

Ms. Saisunee Hanpratuangsilp, Head of Information Technology and Digital Business Support Group, Krungsri Bank, revealed that, “Krungsri is committed to pushing the country's financial infrastructure to keep pace with the digital age. Participating in this test is another important step in driving the development of Thailand's Digital Finance Ecosystem. It reflects the readiness of the Thai banking sector to support the transition to a new financial system in a stable and sustainable manner.”

“This participation confirms Krungsri's Human-Centric Innovations approach in using innovation to solve problems in online commerce on social commerce platforms. It helps buyers avoid fraud, ensures they receive goods that match their orders, and provides sellers with their own reliable sales channels, reducing reliance on high-Gross Profit (GP) marketplaces,” Ms. Saisunee added.

THBC is an electronic data unit issued by Krungsri Bank under the Enhanced Regulatory Sandbox testing framework and has a fixed value. THBC is equivalent to Thai Baht at a 1:1 ratio (1 THBC equals 1 Baht), with 100% of the underlying asset being held in physical Thai Baht. It utilizes Smart Contract technology to automate payment terms and is built on a Blockchain system to support secure, transparent, and verifiable digital transactions.

In this testing phase, Krungsri has mined 2 million THBC coins within the ecosystem using the ERC-20 standard, Smart Contracts, and integrated logistics services. This is being tested as a secure payment system for online sales on various social commerce platforms such as Facebook, Line, and Instagram. Buyers and sellers can transfer and receive payments using THBC via the Krungsri Coin application, developed specifically for this testing. In this test process, the buyer and seller agree on a normal online transaction.

However, the payment for the goods is made using THBC transferred via the Krungsri Coin app. The THBC is only transferred to the seller after the buyer receives and verifies that the goods match the agreed-upon specifications. This mechanism enhances trust between buyers and sellers, reduces the risk of online fraud, and elevates the buying and selling experience to be more transparent and secure. Currently, THBC is open for limited testing by over 400 online buyers and merchants between September and November 2025, and is not yet available to the general public outside of this testing framework.

In the future, Krungsri plans to seek collaboration with business partners to test THBC under the Enhanced Regulatory Sandbox framework to ensure its potential for both the public and business sectors. This will be a key tool in transforming Thailand's payment system to be modern, secure, and truly meet the needs of the digital economy.
