Capabilities

Key Features

Advanced security meets user-friendly design

SPHINCS+ Cryptography

NIST-approved FIPS205 quantum-resistant signatures with multiple security levels.

Local Security

AES256 encryption, Scrypt password hashing, and secure IndexedDB storage.

Light Client

True light wallet with CKB light client node - no middleman RPC endpoints.

Custom BIP39

Enhanced mnemonic standard with 36-72 word phrases for quantum-level security.

Cross-Platform

Native apps for Windows, macOS, Linux, and web demo for browsers.

Wallet Recovery

Automatic wallet restoration from seed phrases with sequential key generation.

Protection Levels

Quantum-Safe Security Categories

Choose your security parameter based on your needs.

1

Category 1

128-bit Security

36-word mnemonic. Equivalent to AES-128 key search resistance.

3

Category 3

192-bit Security

54-word mnemonic. Equivalent to AES-192 key search resistance.

5

Category 5

256-bit Security

72-word mnemonic. Maximum security, equivalent to AES-256.

Recommendation: Start with Sha2-256s for maximum security or Sha2-128s for easier backup management.

12 SPHINCS+ Parameter Sets

  • 2 Hash algorithms: SHA2, SHAKE
  • 3 Security levels: 128, 192, 256 bits
  • 2 Optimizations: 's' (small), 'f' (fast)

Important Notes

  • Minimum 73 CKB per quantum-safe cell
  • Light client sync takes 10-30 seconds
  • Offline signing supported for maximum security

Verification Tool

Binary Signature Verifier

Verify application binaries using SPHINCS+ quantum-resistant signatures.

Select the SPHINCS+ parameter set used to sign the binary.

Paste the SPHINCS+ public key used to sign the binary.

Paste the SPHINCS+ signature for this binary.

How It Works

  1. Upload the binary file you want to verify.
  2. Select the SPHINCS+ variant that was used for signing.
  3. Enter the public key and signature (both in hex format).
  4. Click "Verify Signature" to check authenticity.

Security Notes

  • All verification happens locally in your browser.
  • No data is sent to any server.
  • Binary is hashed using SHA-256 before verification.
  • Quantum-resistant SPHINCS+ cryptography.
