eBTC is a crypto-backed token issued within the Bitcoin liquidity and DeFi ecosystem. It functions as a unified representation of Bitcoin that consolidates liquidity from multiple BTC formats, including native Bitcoin, Bitcoin liquid staking tokens, and wrapped BTC assets. The token is designed to simplify how Bitcoin is integrated into decentralized finance by allowing users to deposit BTC across various standards and receive a single interoperable asset in return, which can then be used across DeFi applications without requiring traditional Bitcoin staking. The underlying infrastructure connects with native Bitcoin Layer 2 networks and supports a range of BTC liquid staking and wrapped token standards. To maintain transparency and solvency, the system relies on Proof-of-Reserve mechanisms that verify the backing assets held within the aggregation layer. Associated with the Starknet and Monad ecosystems, eBTC serves as a bridge asset that helps reduce the fragmentation of Bitcoin liquidity and broadens BTC's utility across multiple blockchain environments.
