**USDC (USD Coin)** is a **stablecoin** pegged 1:1 to the US dollar, meaning each USDC is backed by an equivalent amount of USD or other cash-equivalent reserves. It was launched in 2018 through a collaboration between **Circle** and **Coinbase** via the **Centre Consortium**.
### **Key Features of USDC:**
1. **Stability** – Maintains a 1:1 peg with the US dollar, making it less volatile than cryptocurrencies like Bitcoin or Ethereum.
2. **Transparency** – Reserves are regularly audited and reported to ensure full backing.
3. **Blockchain Support** – Initially issued on Ethereum (as an ERC-20 token), USDC is now available on multiple blockchains, including:
- Solana
- Polygon
- Algorand
- Stellar
- TRON
- Others via bridges
4. **Regulation & Compliance** – USDC is issued by regulated financial institutions, ensuring compliance with US money transmission laws.
5. **Use Cases**:
- Trading and liquidity in crypto markets
- Remittances and cross-border payments
- DeFi (Decentralized Finance) applications (lending, yield farming, etc.)
- Merchant payments (where accepted)
### **How Is USDC Backed?**
- USDC reserves consist of **cash and short-term US Treasury bonds**, held in regulated US banks.
- Monthly attestation reports are published by independent accounting firms (e.g., Grant Thornton) to verify reserves.
### **USDC vs. Other Stablecoins**
| Feature | USDC | USDT (Tether) | DAI |
|--------------|------|--------------|-----|

### **Recent Developments (2023–2024)**
- **Expansion into new blockchains** (e.g., Base, Arbitrum).
- **Adoption in traditional finance**, including Visa using USDC for settlements.
- **Regulatory scrutiny** (like other stablecoins) but remains compliant.
### **Where to Buy & Store USDC?**
- **Exchanges**: Coinbase, Binance, Kraken, etc.
- **Wallets**: MetaMask, Trust Wallet, Ledger, etc.
- **Direct Minting**: Institutions can mint/burn USDC via Circle.
### **Risks to Consider**
- **Regulatory changes** (possible future restrictions).
- **Counterparty risk** (Circle or reserve banks could face issues).
- **Depeg risk** (unlikely but possible, as seen briefly during the 2023 banking crisis).
### **Conclusion**
USDC is one of the most trusted and widely used stablecoins, ideal for traders, DeFi users, and businesses needing dollar stability in crypto transactions. Its transparency and regulatory compliance make it a preferred choice over alternatives like USDT.
