Stork SMS Security Security is at the core of Stork SMS. Our multi-layered security architecture ensures that your conversations remain private and accessible only to authorized participants.

Core Security Principles

​
1. Zero-Knowledge Architecture

  • We never see your unencrypted messages
  • No access to private keys
  • Minimal metadata collection
  • Client-side encryption/decryption

​
2. Blockchain-Based Access Control

  • NFT ownership determines chat access
  • Immutable permission system
  • No backdoors or admin overrides
  • Transparent verification on-chain

​
3. End-to-End Encryption

  • AES-256-GCM encryption
  • Keys derived from participant wallets
  • Forward secrecy (planned)
  • No key escrow
