On April 2, 2026, Circle announced plans to launch cirBTC, a wrapped bitcoin product designed for institutional users, marking its first expansion beyond stablecoins into tokenized bitcoin infrastructure. The asset will be backed 1:1 by bitcoin, with reserves verifiable on-chain, and is set to launch first on Ethereum alongside Circle’s Arc network.
The move shows Circle is expanding beyond stablecoin issuance into infrastructure built around institutional capital flows.
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.

Wrapped bitcoin allows BTC to be used on networks like Ethereum, enabling access to lending, trading, and collateralized DeFi applications. This has become more relevant as institutions look for ways to deploy idle bitcoin holdings.
Circle is targeting this segment directly. According to its product page, cirBTC is designed for over-the-counter desks, market makers, and lending protocols that require a neutral and secure version of tokenized BTC.
The focus comes as a large share of bitcoin is still unused in DeFi. More than $1.7 trillion worth of bitcoin sits outside DeFi, largely due to concerns around custody risk and transparency.
Circle’s core pitch centers on transparency. Each cirBTC token will be backed by native BTC, with reserves independently verifiable on-chain in real time. This contrasts with earlier models that relied on periodic attestations or third-party reporting.
The asset will also integrate directly with Circle’s existing infrastructure, including USDC, Circle Mint, and its Arc layer-1 network. This allows institutions to mint, move, and deploy assets within a single integrated stack.
The design follows the same model Circle used with USDC, built around reserve transparency and regulatory alignment.
cirBTC is coming. We are bringing the same infra that supports USDC, EURC and USYC to the largest digital asset, creating a neutral infrastructure for new applications for onchain BTC. Read more below. https://t.co/TRAgM78b2u

Circle enters a market already dominated by established players. BitGo’s wrapped bitcoin (wBTC), launched in 2019, remains the largest with a market capitalization of roughly $8 billion. Coinbase’s cbBTC, introduced in September 2024, has grown to around $5.9 billion, according to publicly available market data.
Other exchanges, including Kraken, Binance, and OKX, have also introduced their own wrapped BTC products, each competing on liquidity, custody, and transparency.
Circle’s differentiation lies in its institutional relationships and existing infrastructure. Its USDC stablecoin has seen increased adoption in 2026, as stablecoins accounted for 75% of total crypto trading volume in Q1 2026, based on recent market data.
While cirBTC is positioned as a more transparent and neutral alternative, the challenge is not limited to technology. Existing products already offer proof-of-reserve frameworks and deep liquidity, which remain critical for institutional adoption.
There are also governance considerations. Concerns around custodial control and counterparty risk have affected sentiment toward some wrapped BTC providers in the past, but shifting that trust toward a new issuer requires more than design improvements.
Circle’s entry adds another credible option, but adoption will depend on whether institutions see meaningful differences in execution, not just structure.
The launch of cirBTC highlights a broader shift. As institutional participation deepens, competition is moving beyond asset issuance toward control over the infrastructure those flows depend on.
