  • The December 2025 community token sale raised $61M from 16,700+ participants at a 75% discount to Series B valuation.
  • Noir, a Rust-inspired language for ZK applications, reached pre-release in December 2025 with 600+ GitHub projects using it.

Technical approach

As reported
Privacy

Client-side private execution

Private functions run on user devices, not the network. Private data never touches servers or the blockchain, requiring only proofs to settle on-chain.

ZK Proofs

Zero-knowledge SNARKs

The network uses zk-SNARKs to verify computation without revealing the underlying data, matching the privacy promises of traditional finance.

Language

Noir for ZK development

Noir is a domain-specific language that lets developers write zero-knowledge applications without understanding elliptic curve math or cryptography.
