Work With Us
Soundness is more than a vision, it’s a movement. We’re building an Internet where on-chain assets and transactions aren’t just secure; they’re protected against quantum threats. We’re setting a new standard: blockchain security meets verifiability, resilience, and future-proof protection, powered by PQC and advanced verification layers.
What Drives Us
We’re building the security layer that lets blockchains survive the quantum era, with post-quantum guarantees and verifiable execution at scale.
