Circle launches cirBTC on Ethereum, targets institutional bitcoin collateral infrastructure
Circle has launched cirBTC, a bitcoin token on Ethereum backed 1:1 by native bitcoin, positioning it as a starting point for building institutional collateral infrastructure. The company said it holds the underlying bitcoin through its own entity and manages reserves separately from corporate assets, with on-chain reserve visibility. The product is designed to work with Circle Mint and USDC flows and is expected to add Arch and other chains.
