Qustody is non-custodial digital asset infrastructure on Quantum Chain — wallets, policy-controlled transfers and QRC-20 asset tokenization, every signature secured by Qeys. Your keys never leave your control.
A Fireblocks-compatible API surface on quantum-resistant rails.
Every transaction is signed with Qeys, our proprietary post-quantum signature protocol — engineered to remain secure against both classical and quantum adversaries.
Callback, remote and HSM (gRPC/mTLS) signing flows. Qustody orchestrates — private keys are generated, stored and used exclusively on your side.
Velocity limits, allow-lists, multi-party approval quorums and role-based access control enforced before anything is signed.
Deploy, mint, burn and pause QRC-20 tokens from audited templates — tokenize real-world and financial assets directly on Quantum Chain.
Identity verification and transaction screening are first-class: onboarding and transfers are compliance-gated by design.
Hash-chained, tamper-evident audit log across every tenant action — verifiable independently, exportable for regulators.
Create your organization and complete KYC/KYB through our integrated verification journey.
Register post-quantum wallets with cryptographic ownership proof, set policies, and move QUANTUM under multi-party approval.
Deploy tokens from audited templates and manage the full lifecycle — mint, burn, pause — via API or dashboard.
Every plan includes post-quantum signing, the policy engine and the hash-chained audit log. Usage beyond the included transactions bills as overage.
Developer sandbox on devnet. Build and test your integration end to end before going live.
Go live on Quantum Chain mainnet. For teams launching their first custody product.
Dedicated tenancy for growing platforms: sub-tenants, regulated tokens, custom bytecode.
Self-hosted or dedicated managed deployment with contractual SLAs and a named TAM.
The Qustody signing app. Generate Qeys, prove wallet ownership and sign every transaction locally — private keys never leave your machine.
