QU3 is a platform for quantum-safe MCP servers that blend post-quantum cryptography, AI orchestration, and inter-chain routing and auditing to enable private, verifiable compute across blockchains. The core promise is one-command SDKs to deploy attested, quantum-sealed MCP servers that produce instant, verifiable results and publish tamper-proof audit data cross-chain. Public pricing or plans are not disclosed on the site. The product is explored across several pages: a main site emphasizing developer onboarding and decentralized compute; docs with overview messaging; an integration page noting Python, Rust and Go SDKs; a monitor page with an attestation status UI; a dashboard with wallet-based onboarding and templates; a dossier site detailing the technical architecture including lattice-based CRYSTALS Kyber KEM, hash-based signatures, deterministic on-chain audit logs, inter-chain policy routing, forward-secure key rotation and zero-downtime redeployments. Privacy policy exists detailing wallet and account data. Product Hunt lists the product as private, verifiable AI inference across Web3. While GitHub content is referenced, public repo details were not captured. No public pricing was found.
