FDUSD
First Digital USD — a Hong Kong-issued, fiat-backed USD stablecoin from First Digital, gaining usage especially on Binance and BNB Chain.
FDUSD is a fiat-backed dollar stablecoin issued by First Digital Group, a Hong Kong-based regulated trust company. Reserves are held in segregated accounts of cash and short-term Treasuries with monthly third-party attestations.
The token launched in mid-2023 and grew rapidly after Binance adopted it as a preferred zero-fee trading pair following its 2023 BUSD wind-down. As of 2026 FDUSD is one of the larger non-USDT / non-USDC stablecoins by trading volume.
