Changelog

All notable changes to QuantumSafe are documented here.

​

v1.0.0 — 19-Chain Support

Released: 2026-03-15 Production-ready release with comprehensive multi-chain support across EVM and non-EVM ecosystems.

​

Highlights

• 19 chains supported — Full scanning and attestation across all major blockchain networks
• Non-EVM support — Solana, Bitcoin, Cosmos, and Tron with chain-specific address validation
• NodeReal RPC integration — High-performance RPC endpoints for EVM chain data retrieval
• Sonic (prev. Fantom) — Fantom chain converted to Sonic following the network rebrand

​

Supported Chains

​

Chain-Specific Scoring

• Solana: W1 always scored at 40 (address = public key). Chain grade: F.
• Bitcoin: UTXO model awareness — unspent outputs are hash-protected. Chain grade: D.
• zkSync: Chain grade C (ZK-proof research overlaps with PQC).
• All other chains: Chain grade D.

​

Features

• PQC Key Generation — Generate ML-DSA-44, ML-DSA-65, ML-DSA-87, and SLH-DSA-128s key pairs
• Hybrid Signing — Create dual ECDSA + ML-DSA attestations
• Verification — Verify hybrid attestations by ID or raw components
• Wallet Scanner — Scan wallet addresses for quantum vulnerability (W1-W4 risk scores) across 19 chains
• Chain Readiness Grades — A-F grading for blockchain PQC preparedness
• Non-EVM address validation — Solana (base58), Bitcoin (1/3/bc1), Cosmos (cosmos1), Tron (T)

​

SDKs

• TypeScript SDK (@quantumsafe/sdk) — v1.0.0
  • Key generation using Web Crypto CSPRNG
  • Full API client with TypeScript types
  • Browser and Node.js 18+ support
  • 19-chain address validation
• Python SDK (quantumsafe) — v1.0.0
  • Key generation using pqcrypto library
  • Sync and async client support
  • Python 3.9+ support
  • 19-chain address validation

​

API

• Base URL: https://api.quantumsafe.io/v1
• Testnet: https://api.testnet.quantumsafe.io/v1
• Authentication via API keys (qs_pub_* / qs_sec_*)

​

Custody

• BYOK (Bring Your Own Key) — Client-side key generation, server stores public key only

​

Known Limitations

• BYOK custody only (Managed custody coming in v1.5)
• SLH-DSA keys cannot be upgraded to Managed mode
• Chain readiness grades are manually curated (automated tracking coming)
• Rate limits on Free tier are conservative
