Toss and KOMSCO test OP Stack for instant settlement of local vouchers

Toss and the Korea Minting and Security Printing Corporation (KOMSCO) have conducted a proof-of-concept using the Ethereum Layer 2 framework OP Stack to modernize local voucher settlements. The test successfully integrated user deposits, offline/online consumption, and merchant settlement into a single atomic blockchain transaction, enabling instant fund availability. The project aims to improve liquidity for small businesses and enhance transparency in government subsidy distribution. The system is currently in a sandbox environment with no official commercial launch date announced.
