CirBTC von Circle macht Bitcoin zu Sicherheiten auf eigenen Rails

Circle hat cirBTC eingeführt, eine tokenisierte Version von Bitcoin, die dazu entwickelt wurde, den Vermögenswert auf die eigene Blockchain-Infrastruktur des Unternehmens zu übertragen, wie eine Produktseite zeigt, die vom Stablecoin-Emittenten veröffentlicht wurde. Das Token ermöglicht es den Inhabern, Bitcoin (BTC) einzuzahlen und eine 1-zu-1 abgesicherte Darstellung zu erhalten, die innerhalb des Ökosystems von Circle zirkulieren kann, statt untätig in einer Wallet zu liegen. cirBTC ist so konzipiert, auf Arc zu laufen, dem Layer-1-Netzwerk, das Circle entwickelt, um Stablecoin- und Token-Asset-Transaktionen abzuwickeln.

Circle launched cirBTC, a tokenized version of Bitcoin designed to move the asset onto the company’s own blockchain infrastructure, according to a product page published by the stablecoin issuer.
The token lets holders deposit Bitcoin (BTC) and receive a 1-to-1 backed representation that can circulate inside Circle’s ecosystem rather than sitting idle in a wallet. cirBTC is built to run on Arc, the layer-1 network Circle has been developing to settle stablecoin and tokenized-asset transactions.
Wrapped tokens like cirBTC exist because Bitcoin’s own blockchain cannot natively interact with smart contracts on other chains. A wrapped token locks the original asset with a custodian or protocol and mints an equivalent token on a different network, letting that value get used in lending, trading or collateral arrangements it otherwise couldn’t reach.
Circle is best known as the issuer of USDC (USDC), the dollar-pegged stablecoin that reached tens of billions in circulating supply.
Extending that infrastructure to Bitcoin signals an attempt to capture BTC holders as customers of Circle’s broader payment and settlement stack, not just dollar-token users.
Circle’s Long Push Beyond The Dollar Peg
Circle has spent the past two years building out infrastructure beyond USDC issuance, including its Cross-Chain Transfer Protocol and now Arc, its own settlement chain. The company’s September 2025 IPO gave it public-market pressure to diversify revenue past stablecoin reserve interest, which had been its dominant income source. cirBTC extends that diversification into the largest cryptocurrency by market capitalization, an asset Circle has never issued a token against before.

Why Bitcoin Holders Might Actually Bite
Bitcoin’s roughly $1.56 trillion market cap dwarfs total stablecoin supply, yet most BTC sits unproductive in cold storage or exchange accounts.
Tokenizing even a small fraction onto a chain built for stablecoin settlement could route billions in previously idle collateral into Circle’s payment rails. The open questions are custody transparency for the underlying BTC and whether developers building on Arc actually need Bitcoin exposure versus dollar liquidity.
