USD1 is a U.S. dollar–denominated stablecoin issued by World Liberty Financial (WLFI). It is designed to maintain a one-to-one peg with the U.S. dollar and serves as a digital representation of fiat currency on public blockchains.

The token is backed by reserves held in custody by BitGo, a regulated digital asset custodian. These reserves consist primarily of cash and short-term U.S. Treasury instruments, which are intended to fully collateralize all circulating USD1 tokens. WLFI states that this structure aims to provide transparency and reduce counterparty risk in line with established stablecoin models.

The asset is designed for use in payments, decentralized finance (DeFi) applications, and digital asset trading, where it functions as a stable medium of exchange and unit of account. Because it operates on public blockchains, USD1 can interact with smart contracts and be integrated into protocols that require stable collateral or settlement assets.

The Indonesian Rupiah (IDR) is the official currency of Indonesia, issued by Bank Indonesia. With Indonesia being a growing hub for blockchain adoption, IDR-backed stablecoins and crypto trading pairs are emerging, making it easier for local users to access digital assets.
