Two layers.
One post-quantum fabric.
Quantos runs on two layers: a Layer 1 DAG that settles transactions in parallel, and a Layer 0 hub that anchors other chains with post-quantum proofs.
Enterprise-grade rails, launch in weeks.
Post-quantum infrastructure that lets the most ambitious teams build on composable rails, not months of protocol plumbing.
Why builders choose Quantos
How users benefit
The Layer 0 finality hub.
A post-quantum DAG interoperability layer that anchors its finalized state to external chains instead of competing with them. Quantum-safe proofs, sovereign subnets, and native light clients make Quantos a trust anchor for the multi-chain economy, without altering those chains' own consensus.

A composable post-quantum Layer 1 stack for product and protocol.
A quantum-safe DAG that maps each infrastructure layer to a concrete product role, from DAG consensus and WASM runtime to zero-gas settlement and institutional-grade security.
{{ s.body }}
Transparent post-quantum DAG launch status.
The quantum-safe product stack is visible and accessible. Quantos testnet is not live yet. We are finalizing hardening, audits, and release sequencing before opening public network access.

Product and infrastructure evolve together: design the surface, prove the stack, then roll out the network when readiness gates are complete.
