Circle’s wrapped Bitcoin product, cirBTC, launched on Ethereum with institutional-grade infrastructure but minimal on-chain scale. As of Aug. 27, just 40.02 cirBTC tokens were outstanding, backed by 42.51 BTC held across 14 disclosed addresses by Circle National Trust, a federally supervised custodian approved by the Office of the Comptroller of the Currency in July.
The reserve snapshot showed 106.2% backing, a 2.49 BTC cushion above the circulating supply. By comparison, WBTC maintained 116,499 tokens outstanding and cbBTC held 98,668 tokens, making cirBTC’s supply roughly 2,911 times and 2,465 times smaller, respectively.
Circle paired cirBTC with direct minting and redemption for eligible institutions through Circle Mint, alongside USDC distribution infrastructure and planned integration into Arc, the company’s settlement network scheduled for public mainnet launch on Sept. 16. Jeremy Allaire, Circle’s CEO, has described Circle as “the platform for the internet financial system,” positioning the wrapped Bitcoin product within a broader stack that includes custody, stablecoin issuance, and network settlement.
Institutional Credentials, No Visible Trading
CoinGecko’s verified cirBTC contract page showed no tracked 24-hour trading volume, liquidity, or transaction count as of Aug. 29. WBTC recorded $110.49 million in 24-hour volume the same day, with a maximum observed lending exposure of $3.12 billion. cbBTC logged $338.55 million in daily volume and $2.817 billion in peak lending exposure.
Circle argues wrapped Bitcoin should remain “strategically neutral” to avoid conflicts when a wrapped asset is controlled by an operator with its own exchange or lending protocol. Aave governance has proposed onboarding cirBTC, though live collateral support and borrowing demand remained pending as of the reporting cutoff.
Arc and the Integrated Stack
Circle reported more than 100 builders and a validator cohort including major financial and payments companies for Arc. The settlement network could connect Circle’s custody, stablecoin, and wrapped Bitcoin products inside one operating environment. Circle did not name specific validator members or disclose which institutions had adopted cirBTC for direct issuance and redemption.
Circle’s USDC stablecoin reached $73.3 billion in circulation at the end of Q2, with $14.8 trillion in on-chain transaction volume during the quarter. The company paired that existing infrastructure with cirBTC’s launch, positioning the wrapped Bitcoin as part of a vertically integrated financial system rather than a standalone token.
Mechanism and Market Structure
Circle Mint is restricted to eligible institutions; secondary-market users can only transfer the ERC-20 token on Ethereum. WBTC and cbBTC already sit inside established exchange, wallet, and lending networks, giving them distribution advantages that cirBTC’s nascent adoption has not yet matched. Circle did not specify which jurisdictions support direct issuance and redemption through Circle Mint.
The institutional infrastructure underpinning cirBTC reflects Circle’s custody and regulatory credentials. The extreme gap between cirBTC’s 40-token supply and WBTC’s 116,499-token supply illustrates the difference between launching with financial-system plumbing and launching with market adoption. Whether institutions will route Bitcoin through cirBTC instead of established wrapped products remains an open question at this stage.
