Privacy Technologies

Hash-based STARK proofs, stealth addresses and a shielded pool on Solana, each proof checked on-chain.

Circuits in the shipped prover: 5; C0, C1, C3, C6 and C7 (README, 2026-09-23)
Programs on devnet: 4; verifier, pool, registry, relayer (README, 2026-09-23)
Packages in this repository: 8; 7 of them published on npm (README, 2026-09-23)
