Digital asset custody firm BDACS said on Monday it has expanded its won-linked stablecoin KRW1 to Plume, a blockchain network specialising in real-world assets. BDACS said the integration will allow developers, financial institutions and asset issuers to secure won-based payments and liquidity in the Plume ecosystem. KRW1 is pegged 1:1 to the South Korean won and is fully collateralised by won assets deposited at major domestic commercial banks.

Hashed Open Finance, a unit of Web3 venture capital firm Hashed, said on Thursday it released a lightpaper for Maroo, a sovereign Layer 1 blockchain designed for the South Korean won economy. The company says Maroo aims to combine openness and scalability with compliance, auditability and privacy. It plans to use the won as the first target currency and later expand to other fiat currencies. It also features a dual-track transaction model and controls for AI agents.
