Building a secure e-wallet isn't just about encrypting data — it's about designing an architecture where security is inherent at every layer. Here's what goes into a production-grade e-wallet platform.
Authentication Layer
Multi-factor authentication is non-negotiable. A secure e-wallet combines something you have (your device), something you know (PIN), and something you are (biometric). Zeno implements all three, with per-transaction authentication that prevents replay attacks.
Transaction Processing
Every transaction goes through a pipeline of validation, authorisation, and settlement. Key design decisions:
- Idempotency: Duplicate requests don't create duplicate transactions
- Atomic operations: A topup either completes fully or rolls back — no partial states
- Audit trail: Every state change is logged immutably
- Rate limiting: Prevents brute-force attacks and abuse
Data Protection
Sensitive data is encrypted at rest (AES-256) and in transit (TLS 1.3). Personal data is segregated from transaction data, following the principle of data minimisation. Access controls enforce least-privilege at every service boundary.
Compliance Framework
Singapore's regulatory landscape requires compliance with the Payment Services Act, PDPA, and MAS guidelines. A well-architected e-wallet builds compliance into its data flows rather than bolting it on after the fact.
Why Architecture Matters for Partners
When you integrate with Zeno's API, you inherit the security architecture. Your integration doesn't need to handle wallet security, compliance, or fraud detection — the platform handles it. You focus on building great user experiences.
