15 · PLATFORM RELIABILITY & RESILIENCE
Wellex commitment to platform stability, data security, and operational excellence. Version: 6.0 | 12.03.2026 | Public
Overview
Wellex is built on a security-first, resilience-first architecture. This document outlines our engineering safeguards, data protection commitments, and operational standards.
⚠️ All yield figures are targets, not guarantees. Actual results depend on DeFi market conditions and user WVI.
1. Smart Contract Security
Wellex smart contracts undergo rigorous security review before any deployment or upgrade.
| Layer | Mechanism |
|---|---|
| Pre-deployment audit | Dual audit: Trail of Bits + OpenZeppelin |
| Bug bounty | Immunefi — up to $250K payout |
| Real-time monitoring | Forta Agent Network — 24/7 on-chain anomaly detection |
| Upgrade safety | UUPS Proxy + multisig 3-of-5 + 48h timelock |
| Circuit breaker | Auto-pause on abnormal TVL movement |
| Transaction simulation | Tenderly simulation before execution |
2. Biometric Data Protection
Wellex processes biometric data (HRV, sleep, activity) under the highest privacy standards.
| Principle | Implementation |
|---|---|
| On-device first | Raw biometrics processed locally — only WVI score sent to server |
| End-to-end encryption | AES-256 encryption of all health data |
| Federated learning | ML models improve without raw data leaving the device |
| GDPR compliance | DPO appointed · DPIA completed · explicit consent · right to erasure |
| Data minimisation | Minimum viable data stored server-side |
| Secure Element (v2) | TEE on Wellex Band v2 — hardware-signed biometric data |
3. Multi-Chain Infrastructure Reliability
| Component | Safeguard |
|---|---|
| Bridge security | Amount limits + dual validation (LayerZero DVN) + emergency pause |
| DEX aggregation | 3 providers (1inch → 0x → ParaSwap) — best route, lowest slippage |
| Card on-ramp | Multi-provider aggregator — automatic failover between providers |
| Stablecoin diversification | USDC + USDT; auto-rebalance on depeg signal |
| Withdrawal protection | Rate limits + queue + circuit breaker |
| Liquidity buffer | 5–15% TVL held in liquid form at all times |
4. Platform Uptime & SLA
| Service | Target SLA | Monitoring |
|---|---|---|
| Web Dashboard | 99.9% | Grafana + PagerDuty |
| Mobile App (read) | 99.9% | Sentry + Firebase |
| Blockchain interactions | 99.5% | Forta + Tenderly |
| Card on-ramp availability | 99.0% | Provider SLA + fallback |
| WebSocket (real-time data) | 99.5% | SSE fallback |
5. Incident Response
All critical events trigger a structured War Room protocol:
| Event | Response Time | First Action |
|---|---|---|
| Anomalous on-chain activity | < 1 hour | Contracts paused via multisig |
| Stablecoin price deviation >2% | < 30 min | AI auto-exit + rebalance |
| Data security incident | < 4 hours | Isolation + GDPR notification |
| Platform outage | < 15 min | Failover + status page update |
| High withdrawal volume | < 1 hour | Circuit breaker + queue activation |
6. Hardware Reliability (Wellex Band)
| Measure | Detail |
|---|---|
| Dual-source manufacturing | 2+ contract manufacturers — no single point of supply failure |
| Buffer stock | 6-week inventory maintained at all times |
| Quality control | Target defect rate < 2% at acceptance inspection |
| OTA updates | Firmware delivered over-the-air — zero user friction |
| Soft-launch mode | App + WEB available without physical band (manual WVI input) |
7. Privacy by Design
Wellex is built with privacy embedded at every layer — not added as an afterthought.
- No raw biometrics on server — WVI score only
- User owns their data — full export available, deletion within 30 days
- Non-custodial wallet — private keys belong to the user, exportable at any time
- Transparent operations — real-time TVL, yield sources, and platform metrics publicly viewable
- GDPR · VARA · MiCA-aligned architecture
