What Is USDC?

USD Coin (USDC) is a stablecoin pegged 1:1 to the US dollar. Launched in 2018 by the CENTRE Consortium (a collaboration between Circle and Coinbase), USDC operates as an ERC-20 token on Ethereum and has expanded to Solana, Algorand, and Stellar.

Key Features:

• Transparent Reserves: Monthly third-party audits verify dollar-backed reserves.
• Multi-Chain Support: Cross-chain transfers enable seamless use across blockchains.
• Regulated Issuance: Complies with money-transmitter laws and AML protocols.

Why USDC Matters

1. Stability: Traders use USDC to hedge against crypto volatility.
2. Efficiency: Enables fast, low-cost cross-border payments.
3. DeFi Integration: Fuels lending, borrowing, and liquidity pools (e.g., Aave, Compound).
4. Institutional Trust: Circle’s compliance framework appeals to corporate treasuries.

How USDC Works

Step-by-Step Process:

1. Deposit USD: Users send dollars to Circle’s bank account.
2. Mint USDC: Circle issues equivalent USDC tokens on the blockchain.
3. Use or Transfer: Tokens are spent, traded, or sent globally.
4. Redeem: Users return USDC to Circle to withdraw USD (tokens are burned).

Technical Backbone:

• Smart Contracts: Govern minting/burning.
• Reserve Management: Holds cash and Treasury bills.
• Attestations: Monthly audits ensure 1:1 backing.

How Circle Makes Money

1. Interest on Reserves: Earns yield from T-bills and cash holdings.
2. Fees: Charges for minting/redemption and premium APIs.
3. Partnerships: Revenue-sharing with exchanges and wallets.
