Financial infrastructure firm Circle officially launched its wrapped Bitcoin token, cirBTC, on the Ethereum blockchain on June 8, 2026. The move aims to bring institutional-grade, Bitcoin-backed collateral to decentralized finance (DeFi) markets. Circle (NYSE:CRCL), the issuer behind the widely used USDC stablecoin, ensures that each cirBTC token is fully backed 1:1 by native Bitcoin (BTC) held in regulated custody.
The launch provides a transparent way for institutions to deploy BTC as collateral without selling their underlying holdings. While Bitcoin remains the dominant digital asset, its lack of native smart contract functionality has long limited its use on Ethereum.
By bridging this gap, Circle is targeting market makers, over-the-counter (OTC) trading desks, and treasury managers who require regulated entry points into the shifting Bitcoin market structure.
Native BTC reserves for cirBTC are managed by a regulated Circle entity and kept separate from the company’s corporate assets. This structural separation is designed to offer the same level of security and compliance that institutional users expect from Circle’s existing stablecoin products, USDC and EURC.
Demand for such a product has been building for years as firms seek to unlock yield within lending protocols and decentralized exchanges (DEXs).
Circle targets institutional Bitcoin collateral market
The introduction of cirBTC places Circle in direct competition with established wrapped Bitcoin providers. BitGo-issued Wrapped Bitcoin (WBTC) currently leads the segment with a market capitalization of roughly $8 billion. Meanwhile, Coinbase Wrapped Bitcoin (cbBTC) has reached approximately $5.9 billion in market capitalization following its launch in September 2024. The total wrapped BTC market is currently valued at around $9 billion.
Circle is framing its entry around the principle of “neutrality,” noting that its incentive is to drive widespread adoption rather than funneling activity to a specific trading platform. To ensure high levels of trust, the company integrated Chainlink Proof of Reserve technology.
This allows counterparties to perform real-time, on-chain verification of the underlying BTC holdings, addressing concerns that unbacked stablecoin risks or wrapped assets could destabilize DeFi protocols.
Institutional users can mint and redeem the new token through Circle Mint, the firm’s dedicated platform for digital asset liquidity. This integration creates what the company calls a “single Circle-native end-to-end stack.” While the supply is currently small—standing at 0.0097205 cirBTC across seven holders as of June 9—the firm expects growth as more institutions clear the regulatory hurdles for participation.
Integration with Chainlink and Arc infrastructure
The use of Chainlink technology provides multi-address transparency, allowing users to verify reserves directly on the Bitcoin blockchain. This automation is a critical feature for institutional treasury management, where manual audits are often seen as too slow for high-frequency DeFi environments. Circle first flagged its intention to launch this product in April 2026 before the official Ethereum rollout this week.
Looking ahead, Circle plans to expand cirBTC beyond Ethereum using Arc, its layer-1 blockchain infrastructure. This expansion will likely increase the asset’s utility across various tokenized asset platforms and stablecoin-driven liquidity pools. The strategy mirrors the broad multi-chain availability seen with USDC, ensuring that market confidence remains resilient despite ongoing geopolitical shifts.
The company’s ability to fund these expansions was bolstered by a $222 million capital raise via its ARC token sale in May 2026. This liquidity supports Circle’s goal of making Bitcoin as easy to use in DeFi as fiat-backed dollars.
By providing a regulated alternative to existing bridges, Circle aims to capture a market share that was previously hesitant to use offshore or less transparent wrapped products.
Equity market headwinds for Circle Internet Group
Despite the technological milestone, Circle Internet Group (NYSE:CRCL) has seen its shares underperform in the public markets recently. As of June 10, 2026, the stock was trading at $81.1, marking a 19.6% decline over the past week and a 28.7% drop over the last month. The stock is currently trading roughly 43% below the average analyst price target of $143.48.
Financial data from the firm’s January 2024 registration statement showed FY2023 revenue and reserve income of $1.45 billion. However, valuation platform Simply Wall St recently flagged that shares may be trading as much as 122.1% above their estimated fair value. With a total market cap of $22.
51 billion, the company is under pressure to prove that new products like cirBTC can drive enough fees to justify its current valuation.
The success of cirBTC will likely depend on whether institutions prioritize Circle’s regulated pedigree over the deep liquidity already present in WBTC and cbBTC. For now, the firm is inviting interested parties to join a waitlist at circle.com/cirbtc. This cautious rollout suggests Circle is prioritizing compliance and technical stability as it attempts to become the primary custodian for Bitcoin in the DeFi ecosystem.
