USDC (USD Coin)
What is USDC (USD Coin)?
USDC (USD Coin) is a stablecoin — a type of cryptocurrency that is pegged 1:1 to the US Dollar. This means 1 USDC is always intended to equal 1 USD, making it a low-volatility digital asset suitable for payments, savings, trading, and DeFi.
USDC is issued and managed by Circle and Coinbase through the Centre consortium, and it's fully backed by dollar reserves or equivalent assets, with regular audits for transparency.
How does USDC work?
Pegged to the US Dollar – For every USDC in circulation, $1 is held in reserve (bank deposits, short-term US Treasuries).
Blockchain-based – USDC exists as a token on multiple blockchains, including Ethereum, Solana, Avalanche, Polygon, and more.
Transparent issuance – Circle publishes monthly attestation reports to prove reserves backing USDC.
Instant and global transactions – Users can send USDC across the world in seconds for low fees compared to traditional banks.
Why is USDC important?
Stable value – Unlike Bitcoin or Ethereum, USDC doesn’t fluctuate wildly — always close to $1.
Key tool in DeFi – Used in liquidity pools, lending, staking, and trading as a stable base asset.
Fiat on/off ramp – Makes moving between crypto and fiat systems easy.
Trusted and regulated – Issued by companies under US financial regulations.
Used in payments and payroll – More companies are paying salaries and invoices in USDC.
