Security Architecture

Engineered with military-grade cryptography, zero-custody standards, and defense-in-depth protections.

Non-Custodial Escrow

Smart contracts built on OpenZeppelin standards ensure LionexBridge operators cannot access, expropriate, or seize your locked crypto without verifiable arbiter consensus.

Argon2id & Nonce Auth

Password hashing utilizes Argon2id with memory-hard parameters. Wallet verification uses unique cryptographic nonces with replay protection across BSC sessions.

AES-256-GCM Encryption

User payment accounts and sensitive banking details are encrypted with authenticated AES-256-GCM at rest using keys isolated from MySQL database records.

Append-Only Audit Trails

All administrative decisions, status transitions, and user security events are recorded in immutable, append-only audit tables that cannot be cleared or pruned.
