The issuer of First Digital USD (FDUSD) is FD121 Limited, branded as First Digital Labs. Its parent company, First Digital Trust, is a qualified custodian and trust company headquartered in Hong Kong. On June 1, 2023, they officially announced the launch of FDUSD, a stablecoin pegged to the US dollar and regulated in Asia.


Upon the launch of FDUSD, First Digital stated that as a company registered under Hong Kong’s Trust Ordinance, they are required to hold all FDUSD reserves in segregated accounts with regulated financial institutions in Asia. This measure ensures that FDUSD reserves are not commingled with other assets of First Digital Trust Limited.


Notably, Binance founder CZ tweeted about the launch of FDUSD as soon as it was announced.



  • CEO of First Digital


Public information indicates that the CEO of First Digital is Vincent Chok.


According to LinkedIn, in addition to his role as CEO of First Digital, Vincent Chok has served as CEO of First Digital’s parent company, Legacy Trust Company Limited, since 2015. Furthermore, the current COO of First Digital, Gunnar Jaerv, previously held positions as the Head of Proprietary Trust and Head of the Digital Asset Department at Legacy Trust Company Limited, where he worked for seven years.




For every unit of FDUSD in circulation, the designated custodian, First Digital Trust Limited, securely holds an equivalent amount of USD reserves. This arrangement ensures that users can seamlessly exchange FDUSD.


FDUSD’s smart contract adheres to the widely recognized ERC-20 token standard and has undergone rigorous auditing by Peckshield, further enhancing its reliability and security.

To improve accessibility, FDUSD is issued on both the Ethereum and BNB Smart Chain networks, utilizing Proof of Stake (PoS) or Proof of Staked Authority (PoSA) consensus mechanisms. This setup ensures the immutability and transparency of FDUSD. Users can also flexibly integrate FDUSD into smart contracts, enabling faster and smoother transactions.

  1. Transferability:


FDUSD, as a fungible digital currency, supports seamless and frictionless transactions, making it a convenient choice for various applications.


  1. Redeemability:


FDUSD is backed by high-quality reserve assets (cash and cash equivalents), allowing holders to redeem their FDUSD tokens for an equivalent amount of USD. This feature ensures the security of the stablecoin’s reserves, with users trusting that FDUSD will always be supported 1:1.


  1. Programmability:


As a blockchain-based cryptocurrency, one of FDUSD’s significant advantages is its ability to provide cost-effective, low-fee transactions. Unlike traditional financial transactions, which often incur high fees, blockchain-based transactions typically involve lower costs. This cost efficiency makes FDUSD an attractive economic choice for users.


  1. Low Fees:


FDUSD offers highly cost-effective and low-fee transactions due to its blockchain foundation. This makes it an economical choice compared to traditional financial transactions, which often incur high fees.


  1. Operation on Decentralized Networks:


As a stablecoin based on blockchain technology, FDUSD operates on decentralized networks distributed across multiple nodes. This enhances transparency, security, and resilience, as no single entity has full control over the network.


  1. Independence from Bank Insolvency


The fiat reserves backing FDUSD are held in segregated accounts by the designated custodian, First Digital Trust Limited. This means that even in the unlikely event of the custodian’s insolvency, the reserves supporting FDUSD (held by or on behalf of the custodian) remain separate from the custodian’s other assets and are protected, ensuring the stablecoin remains pegged and secure.




FDUSD, while not yet reaching the same level of maturity as more established stablecoins like USDT and USDC, shows significant potential. Its market capitalization growth is a testament to this potential. Recent developments, such as Binance’s decision to phase out BUSD, could positively impact FDUSD‘s adoption.


Additionally, FDUSD’s whitepaper outlines a strategic vision that includes building partnerships with various stakeholders. These partnerships aim to enhance accessibility through collaborations with exchanges, encourage merchant adoption through partnerships with payment processors, provide user-friendly wallet solutions, and promote decentralized lending and trading through DeFi projects. This strategic plan indicates the team’s clear objectives, and if they can achieve these goals, particularly with Binance’s support, FDUSD appears to have a promising future.


A critical advantage of FDUSD is its USD backing, making it a safer choice compared to algorithmic stablecoins. As long as its reserves are fully backed by cash or cash-equivalent assets, this stability could lead to wider adoption.
