First Digital USD (FDUSD) — Complete Guide

FDUSD is a fiat-backed stablecoin issued by First Digital Trust, a Hong Kong-based qualified trust company, launched in June 2023. It quickly achieved a $2–3 billion market cap largely through Binance's promotional integration — Binance offered zero-fee BTC/FDUSD and ETH/FDUSD trading pairs, driving massive adoption. FDUSD is primarily a Binance ecosystem stablecoin backed by cash and high-quality liquid assets regulated under Hong Kong trust law.

First Digital Trust holds FDUSD reserves in segregated trust accounts under Hong Kong Trusts Ordinance, with monthly attestations by Prescient Assurance. Each FDUSD token is redeemable for one USD through First Digital's institutional redemption process. Users interact with FDUSD primarily through Binance (for trading) or through BNB Chain DeFi. The Sui chain deployment targets the growing Sui DeFi ecosystem. First Digital Trust is regulated by the Hong Kong Monetary Authority (HKMA), providing regulatory oversight in Asia.
