Optimism vs USD Coin FAQ
- What is Optimism?
- Optimism is an optimistic rollup L2 on Ethereum, launched mainnet 2021 by OP Labs. The broader project is the Optimism Collective — a bicameral governance with the Token House (OP holders) and Citizens' House (soulbound voting for Retroactive Public Goods Funding).
- What is the OP Stack?
- Open-source codebase for launching optimistic rollups. Base (Coinbase), World Chain, Zora, Mode, and dozens of others are OP Stack chains. Together they form the "Superchain" — shared sequencing infrastructure, bridging, and a common governance layer. It is the dominant rollup framework by chain count.
- What is USDC?
- USDC (USD Coin) is a dollar-pegged stablecoin issued by Circle. Each USDC is backed 1:1 by USD-denominated reserves (cash and short-duration US Treasuries), attested monthly by a major accounting firm and held at regulated US banks.
- Is USDC safe?
- USDC has maintained its peg since launch in 2018, with the notable exception of a brief de-peg in March 2023 during the Silicon Valley Bank collapse, where Circle had exposure. Reserves are now diversified across multiple banks and short-dated Treasuries.
