First Digital USD FDUSD
the Hong Kong dollar twin, built to stay at $1
🎭 the newcomer at the stablecoin table, careful and tidy, with a briefcase of Treasury bills always within reach
💬 “My whole job is to be boring. One token of me should always trade for one dollar, no surprises. Behind that promise sits a trust account full of US Treasury bills. A rival once shouted that I was broke, and for one nervous afternoon people believed him, then the dollar came back and so did I.”
- FDUSD is a stablecoin, a coin that is meant to always equal $1.
- It is backed by real reserves: cash and US Treasury bills held in trust accounts, not by an algorithm.
- Launched June 2023 by First Digital Labs in Hong Kong; by 2026 it lives natively on about six blockchains.
- In April 2025 it briefly slipped to ~$0.87 during a scare, then recovered toward $1 within about a day.
📖 The Story
June 1, 2023. Hong Kong switched on a fresh set of rules for digital assets, and on that very day a new dollar coin stepped onto Ethereum and BNB Chain. First Digital Labs called it First Digital USD. Its pitch was simple and a little dull on purpose: while other coins jump around in price, this one would just sit at a dollar.
The trick behind that calm is not magic. For each FDUSD that exists, the company keeps a real dollar's worth of cash and short-term US government bills locked away in trust accounts. When you hand over dollars, new tokens are made; when you give tokens back, they are destroyed and you get dollars. The coin should always shadow the size of that reserve.
April 2024. Traders liked having a tidy place to park value, and FDUSD swelled to about $4.4 billion in circulation, its high-water mark. Then the tide went out and the supply shrank sharply over the next two years.
April 2, 2025. The quiet coin had its loudest day. Justin Sun, the founder of Tron, publicly claimed that First Digital's custodian was 'effectively insolvent'. Fear did the rest, and FDUSD briefly dropped to around $0.87. First Digital answered that the claim was false, that the real argument was about a different coin called TrueUSD, and that FDUSD was still fully backed by Treasury bills. The peg climbed back toward $1 within about a day, and the company honored the redemptions people asked for.
📊 Stats
🧩 How it works
FDUSD has no mining and no chain of its own. It is an issued token that rides on other blockchains, so its value does not come from a network agreeing on it. It comes from the reserve. Put a dollar in and a new token is minted; send a token back and it is burned while a dollar leaves the vault. That two-way door is what keeps one FDUSD worth one dollar.
Because of this, FDUSD's supply is never capped or mined. It grows and shrinks with deposits and redemptions, the same way Tether and USD Coin do.
🌗 Light & Shadow
- Steady by design. One FDUSD is meant to always equal $1, which makes it a quiet shelter when other coins swing
- Backed by real-world assets, mostly cash and short-term US government bills, not by a fragile algorithm
- Spread across about six blockchains by 2026, so it is easy to move and widely used in trading and DeFi
- You are trusting a company, not code. If the reserves are not really there, the $1 promise is only a promise (the whole point of the April 2025 scare)
- It has already broken its peg once, dipping to about $0.87, which shows the calm can crack on a single rumor
- Far smaller than its rivals, with circulation down from a ~$4.4B peak to the few-hundred-million range by 2026 (less depth means a shock hits harder)
🧬 Evolution lineage
FDUSD is not a fork of any coin. It is a younger sibling in the family of dollar-backed stablecoins, standing next to Tether and USD Coin, run by a different company. It is also tangled, through a shared Hong Kong custodian, with TrueUSD, whose reserve dispute caused the 2025 scare.

❓ FAQ
- What is First Digital USD?
- A stablecoin meant to always be worth $1. For every token in circulation, the issuer says it holds a dollar's worth of cash and US Treasury bills in trust accounts. You use it to park dollar value on a blockchain for trading and payments.
- Who makes FDUSD, and is it the same as Tether?
- It is issued by First Digital Labs, tied to a Hong Kong custodian called First Digital Trust. It is the same kind of coin as Tether (USDT) and USD Coin (USDC), a dollar-backed stablecoin, but a different, newer, and smaller company runs it.
- Did FDUSD lose its $1 peg?
- Yes, briefly. On April 2, 2025 it dipped to about $0.87 after Tron founder Justin Sun called its custodian 'effectively insolvent'. First Digital said the claim was false and was really about a different coin, TrueUSD. FDUSD climbed back toward $1 within about a day.
- Where can I buy FDUSD?
- On crypto exchanges, where it shows up mostly as a trading pair, you swap it for other coins. It is built to stay near $1, so people hold it to sit out volatility, not to chase gains. (Information only, not an exchange or investment recommendation.)
