# Security & Audit

T-Blocks digital infrastructure is subject to security reviews and audits.

**Smart contract audits.** Token smart contracts are reviewed by independent security auditors before deployment. Audit reports are available to investors and distribution partners upon request.

**Infrastructure security.** The XRP Ledger's security is maintained by its decentralised validator network and 12+ years of production operation. The ledger has never experienced a successful attack or unplanned downtime.

**Operational security.** The Management Company maintains operational security procedures for token issuance, redemption, and administration, including multi-signature authorisation for critical operations, key management protocols, and incident response procedures.
