Circle Unveils cirBTC — Its Own Wrapped Bitcoin for Institutional DeFi
USDC issuer Circle has announced cirBTC, a wrapped Bitcoin token backed 1:1 by real BTC, targeting institutional participants and the broader DeFi ecosystem.
Circle Enters the Wrapped Bitcoin Arena
Circle, the company behind the USDC stablecoin, has announced cirBTC — a tokenized version of Bitcoin backed 1:1 by actual BTC with on-chain verifiability. The firm has opened a waitlist for early access to the new product.
«Circle Wrapped Bitcoin is coming. Backed 1:1 by BTC and readily verifiable onchain, cirBTC is being built to work seamlessly with Circle infrastructure and the broader DeFi ecosystem.» — Circle (@circle), original post
Why It Matters
The launch of cirBTC could significantly reshape the wrapped Bitcoin market, which has so far been dominated by BitGo's WBTC and Coinbase's cbBTC. Circle brings its reputation as the issuer of the largest regulated stablecoin, robust infrastructure, and a clear institutional focus to the competition. For DeFi, another high-quality wrapped BTC product means deeper liquidity and expanded utility for Bitcoin beyond its native chain.
Technical Architecture and Integration
Circle plans to fully integrate cirBTC into its existing technology stack. The token will be supported by the Arc blockchain and the Circle Mint platform, which currently handles stablecoin issuance and redemption. The initial rollout will cover both Arc and Ethereum networks.
According to Circle's website, cirBTC is designed for OTC platforms, market makers, lending protocols, and anyone requiring a neutral, secure, and high-performance tokenized Bitcoin. The company is positioning the product as a "world-class institutional-grade standard."
Circle's Return to Bitcoin Products
The wrapped BTC token marks one of Circle's few non-stablecoin offerings. The company previously operated Circle Pay, a Bitcoin payment service that was shut down in 2019 when the firm pivoted entirely to stablecoins. Beyond USDC, Circle currently manages USYC, a yield-bearing tokenized money market fund. Unofficial reports also suggest the company is preparing a native token for the Arc network.
Competitive Landscape

Several wrapped Bitcoin products already exist in the market. WBTC from BitGo leads with a market cap exceeding $7.9 billion. Coinbase's cbBTC, launched in September 2024, has reached a $5.9 billion market cap according to CoinGecko. Circle will need to compete against these established solutions, banking on institutional-grade quality and deep integration with its own ecosystem.
Recent Controversies Surrounding Circle
The cirBTC announcement comes during a challenging period for the company. In recent weeks, Circle has faced criticism from community members. In March, on-chain investigator ZachXBT accused the issuer of unjustifiably freezing 16 wallets. In early April, ZachXBT and other industry figures criticized Circle's response to the Drift Protocol hack — the company failed to promptly freeze funds linked to the attack despite having the necessary tools to do so.
