Selection Considerations
When evaluating privacy infrastructure: Technical Requirements- Privacy guarantees (pre-trade, execution, post-trade)
- Cryptographic approach (ZK, MPC, TEE, encryption)
- Performance characteristics (latency, throughput)
- Integration complexity with existing systems
- Deployment model (L2, sidecar, middleware)
- Network support (mainnet, L2s, private chains)
- Key management and custody integration
- Compliance and auditability features
- Production maturity and audit status
- Developer tooling and documentation
- Support and SLA availability
- Licensing and commercial terms
Integration Patterns
Most vendors support one or more of these integration approaches:- Native L2 Deployment - Deploy on privacy-focused rollup
- Sidecar Architecture - Privacy layer alongside existing EVM node
- Protocol Integration - Direct integration with protocol APIs
- Middleware Stack - Privacy as composable middleware layer
