01

Fully reserved, one-to-one

Every HKDDig in circulation is backed by an equivalent amount of HKD reserves. Reserve accounts and audit reports are public, and every mint and redemption is recorded on-chain.

02

Real-time mint and redeem

Institutions and eligible users can submit mint or redemption requests 24/7 at 1:1, with transparent settlement rails and risk controls.

03

Native multi-chain

Launching on TRON, Ethereum, BNB Chain and Polygon, with a lock-and-mint bridge so total supply stays verifiable across chains.

04

Built for real use

Serving cross-border e-commerce settlement, supply-chain payments, RWA pricing and on-chain treasury, providing an HKD settlement layer that sits alongside USDT / USDC.

Mechanism

Four steps from fiat liquidity to on-chain HKD

Minting, circulation, bridging and redemption form a closed loop, each step backed by queryable on-chain proofs and reserve movements.

  1. 1

    HKD deposit

    Users deposit HKD into the designated reserve account via bank transfer or FPS; the system confirms receipt and records the reserve increase.

  2. 2

    Equal mint

    HKDDig is minted 1:1 on the target chain, with on-chain supply and reserves updated together.

  3. 3

    Cross-chain

    Cross-chain transfers lock on the source chain and mint on the target chain, keeping total supply aligned with reserves.

  4. 4

    On-demand redemption

    On redemption HKDDig is burned and an equivalent amount is released from the reserve, completing the loop.

i

Peg protection: If the secondary market price moves outside the target band, arbitrage and market-making arrangements guide it back; minting pauses automatically if the reserve ratio falls below the threshold.

FAQ

Questions you may have

How does HKDDig maintain its 1:1 peg?

Each HKDDig corresponds to an equivalent amount of HKD assets in reserve, and minting and redemption both execute at 1:1 HKD. If the reserve ratio falls below the threshold, minting pauses and replenishment is triggered.

Where can I check the reserves?

Reserve addresses will be published at launch and balances are queryable on-chain in real time. The issuer publishes monthly reserve reports and is progressively adding third-party attestations.

Who can mint and redeem?

Minting and redemption are available to institutions and eligible users who have completed identity and compliance review; eligibility rules follow official announcements.

Which chains are supported?

TRON, Ethereum, BNB Chain and Polygon at launch, with further chains added as business requires.

Is HKDDig an HKD or a USD asset?

HKDDig is a digital HKD asset pegged 1:1 to HKD. Like USDT / USDC it is a stablecoin, but both its pricing and reserves are in HKD, for on-chain settlement and accounting in HKD-denominated scenarios.
