Citrea: Bitcoin’s App Layer

Citrea is the first ZK Rollup that scales Bitcoin while preserving its security and decentralization. By ensuring on-chain verifiability and data availability directly on Bitcoin, Citrea makes it possible to build everything on Bitcoin.

With Clementine, Citrea’s trust-minimized bridge (1-of-N), Bitcoin’s trillion-dollar asset base can finally be utilized in DeFi and money markets, unlocking massive untapped liquidity. As Bitcoin’s execution layer, Citrea brings smart contracts to Bitcoin without needing any change its consensus or current form.

Citrea has raised over $16M across two funding rounds, led by Galaxy Digital and Peter Thiel’s Founders Fund. Other backers include Naval Ravikant, Erik Voorhees, Balaji Srinivasan, Eric Wall, Maven11, DiscusFish, and more.
