On 26 September 2018 Circle and the CENTRE consortium introduced USD Coin (USDC): a token meant to be fully collateralised by US dollars in accounts, with regular public reporting of reserves. Circle was the first commercial issuer. Coinbase was a CENTRE co-founder and said it would support the token. The contract is an ERC-20 on Ethereum. More than twenty wallets and venues announced support the same day. CENTRE’s pitch was an open standard several issuers could mint under. The useful sentence is smaller: you give a company dollars, it gives you a token, and you need that company (and its banks) to get dollars back.
Tether’s April 2019 New York order is a different issuer’s balance-sheet week. The 2023 USDC wobble after Silicon Valley Bank is later. Circle’s 2025 IPO is later. Do not rewrite the stablecoins guide as this news item.
What happened
Two regulated-adjacent US firms put a dollar IOU on a public chain with a compliance wrap — mint, burn, blacklist addresses if the issuer so decides. That is a feature of this product, not a bug in Ethereum. Ethereum still just moves the token someone is allowed to sign.
Why it matters
A token that is “a dollar” is a claim on reserves plus operational risk. See stablecoins: useful, not magic. If you use USDC in an app, you are trusting Circle’s books and Coinbase’s distribution as much as you are trusting a blockchain. We will not rank issuers.
What happens next
More venues, more attestations, and a long argument with Tether about what “backed” means. Nothing here is an instruction to buy, sell, mint, or hold USDC, bitcoin, or ether.
