Toss Tests Blockchain Payment Infrastructure with Korea Mint

Toss, a financial services platform operated by Viva Republica, has successfully completed a proof-of-concept for blockchain-based public payment infrastructure in collaboration with the Korea Minting and Security Printing Corporation.

The initiative aimed to explore how digital currency could be incorporated into real-world payment and settlement systems while maintaining connectivity to existing public payment infrastructure.

Viva Republica announced the completion of the project on September 18, following a strategic memorandum of understanding signed by the two organizations in April. The proof-of-concept utilized Optimism as the blockchain infrastructure.

The test environment simulated the full transaction cycle, from users topping up gift certificate tokens with blockchain-based digital currency to payment processing and settlement for merchants. This was designed to demonstrate how blockchain technology could operate alongside established payment infrastructure.
