One score, two worlds.
Web3 SEO × Post-Quantum Security.

Paste any wallet address, contract, or URL and get a unified 0–100 score in ~15 seconds. Download the deterministic PQC capability certificate, with its attestation hash, as JSON or PDF for free.

Network is auto-detected from the address — Ethereum, Polygon, BNB Chain or Avalanche. No need to choose.

Public heuristic preview — computed by a deterministic rules engine (WSEO 60% · PQC 40%), not yet an on-chain attestation. Register it on-chain yourself below (Polygon / BNB / Avalanche) to make it a permanent public record — the full Quantum Echo truth source is issued for attested targets. Deterministic & tamper-evident: the same target always yields the same score under the current engine version — there is no per-target adjustment, not even for us. Anchor it on-chain and the record is permanent.

Full methodology — the dimensions and their weights, how the total renormalises over what was measured, what the coverage level means, and what cannot be measured.
