Frequently Asked Questions

What is the HKD/DAI trading pair and why is it important for users in Hong Kong?

The HKD/DAI pair represents the exchange rate between the Hong Kong Dollar (HKD) and Dai (DAI), a decentralized, USD-pegged stablecoin governed by the Maker Protocol on the Ethereum blockchain. It's important as it provides a direct fiat on-ramp for Hong Kong residents to acquire a censorship-resistant, over-collateralized digital asset. This allows access to the global DeFi ecosystem using local currency, often via efficient payment systems like FPS (Faster Payment System).

How does Dai's price stability mechanism work, and why is it relevant when buying with HKD?

Dai maintains its peg to the USD through a system of over-collateralized loans, known as Vaults, within the Maker Protocol. Users lock up assets like ETH as collateral to generate Dai. This system, governed by MKR token holders who adjust parameters like stability fees, ensures each DAI is backed by excess value. This is highly relevant for an HKD buyer because it guarantees the digital asset they are purchasing has intrinsic, verifiable backing on the blockchain, distinct from centrally-issued stablecoins which rely on audited bank reserves.

What's the difference between buying DAI on an exchange versus minting it through a Maker Vault?

Buying HKD/DAI on an exchange is a simple trade: you swap your fiat currency for existing DAI tokens. Minting DAI via a Maker Vault is a more complex DeFi process. It involves locking up collateral (like ETH or WBTC) in a smart contract to generate new Dai as a loan against that collateral. Minting gives you direct access to liquidity but requires managing your collateralization ratio and paying a 'stability fee' (interest) to the Maker Protocol. For most users, buying on an exchange is the more straightforward fiat on-ramp.

What are the common methods to buy DAI with HKD?

To buy Dai with Hong Kong Dollars, you typically use a cryptocurrency exchange that supports HKD deposits. The most common methods include local bank transfers and the Faster Payment System (FPS) for quick funding. After completing the mandatory KYC/AML compliance checks, you can deposit HKD, navigate to the HKD/DAI or a related trading pair like HKD/USDT, execute a trade on the order book, and then withdraw your ERC-20 DAI tokens to a secure, self-custody digital wallet.

Are there specific fees associated with HKD to DAI transactions?

Yes, several potential fees exist. First, your chosen cryptocurrency exchange may charge a deposit fee for HKD, although FPS transfers are often free. Second, there's a trading fee (a percentage of the trade value) when you execute the buy order. Third, when you withdraw your DAI, there's a withdrawal fee from the exchange and, more importantly, a network fee (gas fee) paid in ETH for the Ethereum blockchain transaction. This gas fee varies with network congestion.

What are the security best practices for storing Dai after purchasing with HKD?

After acquiring DAI with HKD on an exchange, it is crucial to transfer it to a secure digital wallet where you control the private keys (self-custody). For significant amounts, a hardware wallet is the gold standard for security. Always double-check the recipient address before sending. Be wary of phishing scams and never share your private keys or seed phrase. When interacting with DeFi protocols, ensure you are using the correct smart contract addresses to protect your ERC-20 DAI.
