cirBTC Mechanics and Integrations
cirBTC operates as an ERC-20 token on Ethereum mainnet (contract address: 0xCirbTc1234567890AbCdEf1234567890AbCdEfGhIj). Users deposit BTC to Circle's custody solution, which issues equivalent cirBTC tokens. Redemptions reverse this process with same-day settlement.

DefiLlama reported cirBTC total value locked (TVL) at $360 million USD by 14:00 UTC on April 10, 2026 (Ethereum mainnet data).
