Cross Chain DeFi Routing Architecture Lead

I’m ready to move our hybrid DeFi infrastructure from concept to production and need a senior architect who can own the full cross-chain routing stack end-to-end. The core networks in scope are Base (EVM), Solana (SVM) and Sui (Move). On top of that, the platform must expose ERC-4337 account-abstraction rails so we can offer completely gas-free user flows.

Key functional pillars
• Biometric onboarding through WebAuthn so retail users glide straight from KYC into non-custodial wallets.
• True gasless execution driven by ERC-4337 paymaster flows.
• Hardware middleware automation via CEN/XFS drivers to let ATMs, kiosks and embedded banking devices push transactions directly into our rails.

I already run an AI-native development environment (Cursor, Copilot, GPT-powered test generation) and expect you to orchestrate these agents rather than rely on traditional manual loops. Formal verification, differential fuzzing and static-analysis gates need to run automatically on every commit.

What you will hand over
1. A modular routing engine that detects the cheapest path across Base, Solana and Sui in real time and executes atomically.
2. Smart-contract libraries (Move & Solidity) formally verified, with proofs or audit artefacts.
3. A biometric onboarding micro-service that speaks WebAuthn and mints ERC-4337 accounts on demand.
4. CEN/XFS middleware service bridging hardware events to the routing engine.
5. CI/CD pipeline scripts plus IaC for rapid redeploy to our Kubernetes cluster.
6. Complete test coverage: unit, integration, property-based and load tests showing 1 000 TPS at
