Security & Compliance

Security is infrastructure,
not a feature.

Every layer of DeFlow is designed with security as a first principle — from zero-knowledge identity to non-custodial settlement.

Architecture

Zero-PII by design

DeFlow never stores personal information. Emails, names, and identities are processed through HMAC-SHA256 with a rotating salt — then immediately discarded. Only the irreversible hash is stored.

  • Raw email discarded after cryptographic hashing
  • No PII in database, logs, or error reports
  • Automated filters strip sensitive data from all responses
  • Email notifications via secure API. Backend never sees email strings.

Smart Contracts

Rigorously tested

Our Solidity contracts are verified through multiple layers of automated and manual analysis.

Static Analysis

Automated analysis for common Solidity vulnerabilities, reentrancy, and gas optimization issues.

Fuzz Testing

Property-based fuzz testing with millions of random inputs to find edge cases.

Invariant Testing

Property-based invariant checks for critical escrow and fee distribution contract logic.

Access Control Audit

Role separation with multi-sig requirements for administrative functions.

Compliance

Sanctions screening & KYC

Every participant is screened against international sanctions lists before any transaction is allowed to proceed.

  • OFAC, EU, UN, OFSI, MOFA, NBCTF screening
  • Wallet risk analysis and screening
  • 24-hour TTL on AML results. Stale data blocks funding.
  • 3-tier verification: Basic, Enhanced, Corporate

Settlement

On-chain finality

Non-custodial smart escrow with deterministic settlement.

Non-Custodial

DeFlow never holds your assets. Smart contracts manage escrow with deterministic release conditions.

Deterministic Finality

All transactions confirmed with multi-block depth on Ethereum for guaranteed settlement.

Event Reconciliation

On-chain events are immutable financial truth. UI confirms only after chain event verification.

Bug Bounty Program

Found a vulnerability? We take security seriously and reward responsible disclosure.
