Circle Deploys cirBTC on Ethereum, Letting BTC Holders Tap DeFi Without Selling

Crypto Insight Summary: Circle has launched cirBTC, a wrapped Bitcoin token deployed on Ethereum that allows BTC holders to access decentralized finance (DeFi) applications without selling their Bitcoin. The token is fully backed 1:1 by Bitcoin held in reserve, with Circle publishing attestations to verify the underlying assets. Each cirBTC is designed to be redeemable for native BTC, maintaining parity with Bitcoin's value. The launch positions Circle to compete with existing wrapped BTC solutions like WBTC and cbBTC, expanding its product lineup beyond USDC stablecoin. Available through Circle Mint, institutional clients can convert BTC to cirBTC for use across Ethereum-based DeFi protocols. The company stated that additional blockchain support is planned for future expansion, though specific chains were not named.
