unlocking a world of possibilities while maintaining the utmost trust in their financial
interactions.

2. Introduction
Cryptocurrencies have several advantages over fiat currencies as a form of payment. For
example, it’s much faster than a bank wire, has lower transaction costs, is publicly
auditable, and ensures the security and privacy of users' identities. However, there areseveral barriers to the mainstream adoption of cryptocurrencies as a means of payment.
Crypto is also known for its volatile nature, and its value can fluctuate drastically over ashort period of time, making them a risky form of payment and limiting usage in dailytransactions.
Stablecoins are digitally native payment instruments that are designed to maintain astable value compared to an external reference asset, usually a fiat currency such as theU.S. dollar. They provide a bridge between the traditional financial system and thecryptoeconomy, allowing fiat currencies to exist in a form that can move more freely andmore efficiently on blockchains. Unlike conventional payment methods, stablecoin
payments require no centralized intermediary.
Stablecoins are designed to maintain a stable price so users can avoid market volatility
risks.

FDUSD provides users with a stable digital currency that is backed by fiat currency (i.e.
the U.S. dollar), which can help reduce the volatility in the cryptocurrency market. This
makes it more appealing to investors and merchants, who are wary of the volatility
associated with traditional cryptocurrency price fluctuations.
FDUSD can be deployed in use cases that improve the efficiency of financial transactions
by reducing transaction costs and improving the speed and accuracy of thesetransactions in a secure manner. FDUSD can also be deployed in use cases that facilitatecross-border transactions and reduce the fees and processing times associated withtraditional methods.
The stability of a fiat-backed stablecoin is preserved through the maintenance of a 1:1
peg with the corresponding fiat currency. This is achieved by meticulously ensuring thatthe value of the reserve assets held matches or exceeds the total quantity of outstanding
stablecoins. In essence, the reserves support the issuer's commitment to redeem thestablecoin at its nominal value. It is important to note that FDUSD operates underrigorous custodial arrangements.
Furthermore, the FDUSD can be programmed, allowing financial contracts, escrow, andinsurance without intermediaries.

3. Advantages● Transferable
As a fungible form of digital currency, FDUSD enables frictionless and streamlined
transactions, rendering it a convenient choice for a wide range of applications andscenarios.
● Redeemable
FDUSD is backed by high-quality reserves- cash and cash equivalents, which enable
holders the ability to redeem their FDUSD tokens for their equivalent value in US dollars.

This feature provides safety to the stablecoin reserves, and users can trust that FDUSD
is intended to always be 1:1 backed.
● Programmable
FDUSD is programmable, allowing for the creation of smart contracts, escrow services,and insurance arrangements without intermediaries. This programmability empowers
users with greater control over their financial transactions while reducing transaction
costs and increasing transaction speed and accuracy.
● Low Fees
One notable benefit of FDUSD as a cryptocurrency on the blockchain is its ability to offer
cost-effective transactions with minimal fees. Unlike traditional financial transactions,which often incur high fees, blockchain-based transactions generally involve lower costs.
This cost-efficiency makes FDUSD an attractive and economical choice for users.
● Operates on Decentralized Networks
As a stablecoin built on blockchain technology, FDUSD operates on decentralized
networks that are distributed across multiple nodes. In so doing, it enhancestransparency, security, and resilience, as no single entity has complete control over thenetwork.
● Isolated from Custodian’s Bankruptcy
The fiat reserves of FDUSD are held in reserves with the appointed custodian, FirstDigital Trust Limited, in an account segregated from the custodian’s operational account.
This means that even in the unlikely event of the custodian’s bankruptcy, the reserves
backing FDUSD (to the extent they are held with or under the name of the custodian) are
kept separate from the custodian’s other assets and protected, ensuring that thestablecoin remains stable and secure.

4. Technology Stack
Each FDUSD issued into circulation is intended to be backed in a one-­to-­one ratio withthe equivalent amount of corresponding fiat currency held in reserves with theappointed custodian, First Digital Trust Limited.
Smart Contract audit: FDUSD smart contracts implement the ERC20 Token Standard
and are audited by PeckShield.
FDUSD will be issued on the Ethereum and BNB Chain networks, which follow the ERC20and BEP20 standards, respectively. These decentralized blockchains provide consensus
confirmation of transactions using a Proof of Stake (PoS) or Proof of Staked Authority(PoSA) consensus, providing immutability of records and public transparency to market
participants. Both Ethereum and BNB Chain provide the ecosystem of users with theability to incorporate FDUSD into smart contracts, benefitting users with faster, trustless,stable, and frictionless settlements. In time, FDUSD will be considered to be issued onother blockchains to bring the benefits of the token to a broader audience of developers
and end users. The addition of subsequent blockchains will be subject to criteria
covering technical diligence, the extent of market adoption of the blockchain, and riskreview.
By using established public ledgers, market participants can utilize existing monitoring
applications to view coins in issuance and transactions. In this way, participants canfollow coins issued or redeemed by FD121 Limited as well as other on-chaintransactions. Note that distributed ledger technology subject to transaction verification
via the PoS/PoSA consensus mechanism may result in verification fees paid toparticipants engaged in consensus activities. Fees may vary across blockchains.
FDUSD has a robust and secure underlying technology that can handle large volumes oftransactions and ensure the stability of the coin's value. We’ve worked with experienced
blockchain developers and auditors to ensure the stability and security of yourstablecoin.

5. Attestation of Reserve
The attestation process verifies that the entire supply of FDUSD stablecoins incirculation is consistently fully supported by an equivalent value of cash or cash
equivalents held in the secure custody of First Digital Trust Limited.
By undergoing attestations that are carried out by independent auditors, reserves are
made transparent to users, granting them the ability to independently and promptlyconfirm that cash reserves effectively back the stablecoin asset.

6. Potential Use Cases
FDUSD, as many other stablecoins, offers various use cases in both the financial andtechnological sectors due to its inherent stability and digital nature. Note that these use
cases are not services or functions provided or operated by FD121 Limited, but by third
party service providers. Some prominent product and tech use cases can include:
1) Remittances: Stablecoins enable fast and cost-efficient cross-border transactions,making them an attractive option for remittance services. Utilizing stablecoins reduces
the fees and latency associated with traditional remittance methods.
2) Payment solutions: Businesses and merchants can use stablecoins for processing
payments without significant transaction fees or delays. This is especially useful for ecommerce and international transactions where currency conversion and cross-borderfees can add up quickly.
3) DeFi: FDUSD may offer stability to yield farming, lending, and borrowing platforms.
Users can lend or stake their stablecoins to earn interest or participate in liquidity mining
programs.

8. Risk Factors
Issuers of collateralized stablecoins need to ensure robust reserve asset management
to instill confidence, ensure the stability of the peg and avoid a run on the coin withpossible contagion to the financial sector. Like money market funds (MMFs), reserve
assets of stablecoins need to be liquid to allow users to redeem their stablecoins in fiat
currency. Meticulous management of reserve assets underpins users’ confidence instablecoins. A loss of confidence could trigger large-scale redemption requests leading
to the liquidation of reserve assets with negative contagion effects on the financialsystem.

8.1 Potential Risks of Stabilization Mechanism
Similar to other financial products, stablecoins carry risks for investors and users. Theserisks depend on a range of factors, including the design of the stablecoin arrangement
and its applications. Stablecoins that are fully backed by high-quality liquid assets carry
substantially lower risks for investors and users than other stablecoins, particularly
algorithmic stablecoins. A key element of stablecoin issuance is the stabilization
mechanism, which aims at reducing volatility and underpins an expectation thatstablecoins will be redeemed at par, on demand. For most stablecoins covered in thisnote, the stabilization mechanism is a peg to a fiat currency sustained by reserves.
Stablecoin issuers and network administrators face pressure from end users to meet
redemptions at, or very close to, par upon request, even if issuers have no obligation todo so. The ability to meet such requests hinges on the safety and liquidity of the assets
held as reserves. The management of reserves is specified by the governing body(usually the issuer). Reserves are typically held in custody by a third party, such as afinancial institution. Reserves, though, can vary along a continuum from highly liquid to
illiquid depending on the redemption pledge by the issuer and the redemption needsfrom the end-holders.

FDUSD Stablecoin White Paper v.1.0

Page 10

8.2 Investment and Redemption Risks
FDUSD is backed by cash and cash equivalents only. Reserves are managed by reputable
and regulated investment managers. Custody services of the reserves are provided byFirst Digital Trust Limited. Primary risks for users arise from the potential failure of theissuer to fulfill the claimed structural characteristics of the stablecoin. These encompass
the stablecoin's nominal value, the investment mandate of the reserves, and thecommitment to redeem stablecoins for fiat cash.
Investment Mandate
The reserve is composed of cash and a basket of highly liquid US treasury bills of very
short-dated maturity and overnight reverse repos.
Commitment to Cash Redemption
The FDUSD reserve assets are custodied for the Issuer by a Hong Kong registered trust
company in accordance with the client money rules where reserve assets are segregatedfrom the trust company’s own assets to isolate the trust company’s bankruptcy. Subject
to any suspension and other rights set out in the FDD Terms it is intended that FDUSD
can be purchased from and redeemed by FD121 Limited, on a one-for-one basis against
U.S. dollars, notwithstanding the secondary market value of FDUSD.

8.3 Operational Risks
Stablecoins and other crypto assets are exposed to operational risks, including fraudand cyber risks. These risks stem from various factors, including the intricate nature of
the cryptocurrency ecosystem, reliance on third-party service providers like exchanges
and custody services, as well as the absence of effective remedies for the loss or theftof crypto assets. To mitigate these risks, we employ several strategies for improved
security measures to safeguard against cyber threats and implement robust due
diligence processes when engaging with third-party service providers.

8.4 Regulatory Risks
In addition to upholding the fundamental functionalities of stablecoins, our utmost
priority lies in fostering strong collaboration with regulatory authorities. We recognize
the significance of maintaining compliance with applicable regulations, and as such, we
actively engage with regulators to ensure a thorough understanding and adherence tothe evolving regulatory landscape. Our commitment to cooperation serves as the guiding
principle in navigating this dynamic environment as we strive to deliver innovative
stablecoin solutions while upholding the highest compliance standards.

8.5 Counterparty Risks
The involvement of financial intermediaries in custody and redemption processes canintroduce additional risks, such as delays in redemptions and increased costs. In certain
cases, stablecoin issuers may depend on crypto asset exchanges, market makers,
commercial bank/ATM operators, or other money transmitters to facilitate redemption
requests and disburse cash to token-holders. However, this reliance on third parties canpotentially amplify run risks, thereby necessitating careful consideration and risk
management to ensure smooth and efficient redemption processes while minimizing
any adverse effects on token holders.
