[Tutorial]: Stablecoins & CBDCs 101
-
Written for anyone curious how digital cash works on-chain and what central banks are planning—clear steps, no fluff
1️⃣ Why Stablecoins & CBDCs Matter
Stablecoins and CBDCs bridge crypto and traditional money by offering:
- Price stability so you don’t lose 30 % overnight
- Instant settlement without waiting days for bank wires
- Programmability (smart contracts can trigger payments automatically)
- Regulated rails when backed by central banks
They power DeFi, remittances, micropayments, and future digital wallets!
2️⃣ Types of Stablecoins
There are three main models—pick the right one for your use case:
- Fiat-Collateralized (USDC, USDT)
- Backed 1 : 1 by USD or other fiat in regulated reserves
- Lowest volatility but requires trust in the issuer
- Crypto-Collateralized (DAI)
- Over-collateralized with crypto (e.g. $150 ETH for $100 DAI)
- Trustless on-chain but can face liquidation in crashes
- Algorithmic (Franklin, Terra Classic’s earlier model)
- Expands/contracts supply via code to defend the peg
- Higher risk of “depeg” but very capital-efficient when it works
3️⃣ Central Bank Digital Currencies (CBDCs)
CBDCs are digital forms of a country’s fiat, issued by its central bank:
- Retail CBDC
- Digital cash for everyday users via wallet apps
- Can offer programmable features like tax withholding
- Wholesale CBDC
- Restricted to banks and institutions for large-scale settlements
- Improves interbank transfers and cross-border liquidity
Major economies (China, EU, Bahamas) are already piloting various models!
4️⃣ How to Use Them Safely
Whether stablecoin or CBDC, follow these best practices:
- Choose reputable issuers (Circle, Tether, Paxos) or official CBDC apps
- Verify reserves or audits—look for regular attestation reports
- Use trusted wallets compatible with your chosen coin (e.g. MetaMask for USDC, official CBDC wallet for retail)
- Monitor fees & limits—some platforms charge minting or withdrawal fees
That keeps your digital cash reliable and secure!
5️⃣ Risks & Considerations
No money system is perfect—be aware of:
- Regulatory changes that can freeze or blacklist addresses
- Smart-contract bugs in DeFi integrations of stablecoins
- Counterparty risk if reserves turn out to be mismanaged
- Privacy concerns especially with retail CBDCs tracking every transaction
Stay informed and diversify where possible!
