Use of Funds

Key Metrics & Achievements

  • $16.7 million total raised (Series A $14M + Seed $2.7M)
  • First Bitcoin rollup using zero-knowledge technology
  • EVM-compatible - all Ethereum apps can deploy unchanged
  • Founders Fund's first Bitcoin ecosystem investment
  • Developed by Chainway Labs founded in 2022
  • Founded by team of computer scientists led by CEO Orkun Mahir Kılıç
  • Enables Bitcoin to become programmable beyond store of value

Business Model

Citrea operates as a Bitcoin Layer 2 rollup, earning revenue from transaction fees on the network. As developers deploy applications (DeFi, NFTs, games) on Citrea, the platform captures fees from user transactions. The business model scales with application adoption and transaction volume, similar to Ethereum L2s like Arbitrum and Optimism.


Market Opportunity & Competition

Citrea competes in the emerging Bitcoin Layer 2 market with Stacks, Rootstock (RSK), Lightning Network, and upcoming Bitcoin L2s. Citrea differentiates as the only Bitcoin rollup using zero-knowledge proofs for security, EVM compatibility (enabling Ethereum app migration), and institutional backing from Founders Fund. Joey Krug called it "a major milestone in Bitcoin's evolution."
