First Digital USD (FDUSD)

Overview

First Digital USD (FDUSD) is a cryptocurrency designed to represent the U.S. dollar on a blockchain. It belongs to a group of digital assets called stablecoins, which aim to keep a steady value rather than rise and fall like many other cryptocurrencies. The issuer intends each FDUSD token to be backed by one U.S. dollar or an equivalent value of reserve assets. Eligible customers can exchange tokens with the issuer for dollars at a one-to-one rate.

FDUSD gives people a way to move dollar-denominated value through crypto wallets, exchanges, and applications. A payment can be recorded on a blockchain without moving dollars between bank accounts for each transfer. Banks and custodians remain important, however: they hold and manage the assets that support the tokens. This link between traditional finance and blockchain networks defines how FDUSD works.

History & Team

From launch to a new issuer

FDUSD launched in June 2023 under First Digital Labs, part of the First Digital Group. The project first issued the token through FD121 Limited in Hong Kong. In August 2025, issuance moved to FD121 (BVI) Limited, a company based in the British Virgin Islands. First Digital Labs said the change left the reserve custody arrangements, monthly attestations, and service for eligible minting and redemption customers in place. (firstdigitallabs.com)

First Digital Labs identifies Vincent Chok as its founder and chief executive officer. Gunnar Jaerv is its chief operating officer. The wider team brings together work in financial services, custody, legal matters, and digital assets. These roles matter for a stablecoin because its operation involves more than a token contract: it also requires banking relationships, reserve management, and customer checks. (firstdigitallabs.com)

FDUSD began on Ethereum and BNB Chain, then expanded to other networks. That growth has let the same dollar-focused asset serve people using different kinds of wallets and applications. The supported network still matters for every transfer, since a token on one blockchain cannot simply be sent to an address on another. (firstdigitallabs.com)

Technology & How It Works

Tokens, reserves, and redemption

FDUSD connects an on-chain token to assets held off-chain. When an eligible customer supplies dollars through the issuer’s process, corresponding tokens can be issued. When tokens are redeemed, they are taken out of circulation and the customer receives dollars under the issuer’s terms. This issue-and-redeem process ties the token supply to its reserve arrangement. Direct redemption requires an account with First Digital Labs and completion of identity and anti-money-laundering checks. (firstdigitallabs.com)

First Digital Trust Limited provides custody for the reserve assets. The issuer describes those assets as held separately from the custodian’s own assets. Its published reserve information describes cash and cash equivalents, including short-dated U.S. Treasury bills and overnight reverse repurchase agreements. Independent accountants publish regular attestations comparing reserve assets with tokens in circulation. An attestation checks the position covered by that report; it is different from tracking every transfer as it happens. (firstdigitallabs.com)

How FDUSD moves across networks

FDUSD has versions on Ethereum, BNB Chain, Solana, Sui, TON, and Arbitrum. Ethereum and BNB Chain use token contracts compatible with Ethereum-style applications, while other networks use their own token systems. Each version has its own network identity or contract details, even though all are part of the FDUSD system. Network support gives developers different choices for transaction speed, fees, and application design. (firstdigitallabs.com)

On BNB Chain, FDUSD also supports a feature called EIP-3009. It lets a holder sign permission for a transfer while another party submits the transaction on-chain. An application can therefore cover the network fee for the sender. This can make a payment flow simpler, especially when the person paying does not already hold the chain’s fee token. (firstdigitallabs.com)

Tokenomics & Utility

FDUSD’s economic model follows demand for the stablecoin. Its supply can grow when eligible customers mint tokens and shrink when they redeem them. It has no fixed maximum supply in the way some cryptocurrencies do. Its intended purpose is to provide a digital representation of dollar value, so its usefulness comes from transfer and exchange rather than token scarcity. (firstdigitallabs.com)

The issuer’s terms state that holding FDUSD does not itself pay interest or other returns to the holder. Reserve assets may earn income, but that income does not pass to token holders through FDUSD. A separate financial application might offer a way to use the token in lending or another activity; that arrangement would have its own terms, apart from the token’s basic design. (firstdigitallabs.com)

The one-to-one redemption arrangement applies through the issuer’s account process for eligible customers. Other holders commonly obtain or sell FDUSD through exchanges. This creates two connected paths: a direct issuer process governed by account rules, and secondary-market transfers between other participants. (firstdigitallabs.com)

Ecosystem & Use Cases

Trading and on-chain finance

On exchanges, FDUSD can act as the dollar-denominated side of a trade. Someone moving between crypto assets can use it to keep funds in token form between transactions. Its multi-chain presence also makes it available to compatible decentralized applications. These include exchanges and lending platforms where supported FDUSD tokens can be deposited or traded under the application’s rules. The issuer lists integrations across services such as Uniswap, PancakeSwap, Curve, Aave, and several network-specific platforms. (firstdigitallabs.com)

Payments and business settlement

FDUSD can also serve as a payment or settlement asset. A business might receive the token on a supported chain and use a payment provider to convert it into local currency. First Digital’s integration with FOMO Pay, for example, was designed to let businesses accept FDUSD on Ethereum and Solana while receiving fiat settlement. Other announced partnerships focus on cross-border payment systems and banking links for institutional minting and redemption. These uses show how a stablecoin can connect a blockchain transfer with a business’s ordinary cash flow. (firstdigitallabs.com)

Different networks suit different applications. A developer may choose one for a payment tool and another for a finance application. In each case, the application must support the particular FDUSD version being used. The token’s broad network reach gives it more places to operate, while its dollar reference gives those applications a familiar unit for amounts owed, sent, or received. (firstdigitallabs.com)

Advantages & Challenges

FDUSD’s main advantage is its combination of a dollar-focused value model with blockchain transfers. People can send the token between compatible wallets, use it in supported applications, and hold it between crypto transactions. Its presence on several networks gives users and developers a choice of technical environments. Public reserve reports add information about the assets supporting the issuer’s one-to-one redemption model. (firstdigitallabs.com)

Its design also brings practical limits. Users depend on the issuer’s redemption process and on off-chain institutions that hold reserve assets. Direct access requires an eligible account, while other access depends on the services available in a user’s location. Network fees, transaction steps, and application support vary by blockchain. Because FDUSD is designed around the dollar, it also follows the dollar as a unit of value rather than offering the supply-driven behavior of an asset such as Bitcoin. (firstdigitallabs.com)

Where to Buy & Wallets

First Digital USD is available on exchanges including Binance, Gate, and MEXC. Professional investors can also access FDUSD on HashKey Exchange in Hong Kong. First Digital Labs lists decentralized venues including Uniswap and PancakeSwap among the services that support its ecosystem. Direct purchase from the issuer is reserved for eligible businesses, financial intermediaries, and professional clients; retail customers use secondary-market platforms where available. (firstdigitallabs.com)

FDUSD can be held in a wallet that supports the network on which the tokens were received. MetaMask supports token display on Ethereum and BNB Chain and allows users to add supported tokens when needed. First Digital Labs also lists Phantom in its ecosystem. A wallet must be set to the matching blockchain, and the FDUSD token details must match that network. Those two details determine where the tokens appear and how they can be sent. (support.metamask.io)

Regulatory & Compliance

FDUSD’s issuer is FD121 (BVI) Limited. Reserve custody is provided by First Digital Trust Limited, a registered trust company in Hong Kong. The custody firm’s status and the token issuer’s status are separate parts of the arrangement. First Digital Labs says it is working toward regulatory authorization for its stablecoin issuance activities. Its direct customers must complete identity, anti-money-laundering, and counter-terrorism-financing checks. (firstdigitallabs.com)

Rules also differ across places. Hong Kong’s stablecoin issuer licensing regime took effect in August 2025. In the European Union, the Markets in Crypto-Assets regulation sets requirements for issuers of tokens that reference a single official currency. First Digital Labs states that FDUSD is not intended for U.S. persons or entities and does not offer minting or redemption to people located in the United States or acting for U.S. persons. Together, these rules and issuer policies shape where FDUSD services are offered. (hkma.gov.hk)

FDUSD’s Shariah status calls for attention to both the token and its reserves. Holders receive no interest simply for holding FDUSD, but the published reserve approach includes Treasury bills and other instruments that can produce interest-linked income. Islamic finance principles prohibit riba, or interest. As a result, dollar backing alone does not establish a blanket halal status for FDUSD; a Shariah assessment would need to consider its reserve structure and the way the token is used. (firstdigitallabs.com)

Future Outlook

FDUSD’s development has moved from basic exchange access toward more kinds of payment and business infrastructure. New blockchain versions have widened the range of applications that can handle it, while features such as sponsored transfers aim to make those applications easier to use. Partnerships involving payment providers and banking infrastructure show where First Digital Labs has focused its work. (firstdigitallabs.com)

Its future role will depend on continued network and application support, access to banking and custody services, and the rules that govern stablecoins in each market. These factors affect how smoothly people can move between FDUSD on a blockchain and dollars in the banking system. The core idea remains straightforward: make dollar-denominated value usable in digital transactions while maintaining a process for eligible customers to redeem it. (firstdigitallabs.com)

Summary

First Digital USD brings a dollar-backed token to several blockchains. Its supply follows issuance and redemption, its reserves are held through a custody arrangement, and its main uses span crypto trading, on-chain applications, and payments. FDUSD illustrates how a stablecoin can link familiar dollar amounts with the transfer and programming features of blockchain networks. (firstdigitallabs.com)
