While building Sovereign SDK, we've tackled two challenging technical issues critical for decentralized exchanges: - Achieving extremely low-latency transaction execution and log/event handling. - Ensuring real-time durability and failover, so exchanges stay online even under crisis conditions with minimal impact on users. We've architected solutions to address these specifically in Sovereign SDK: - Transaction execution latency: ~1.2 ms at p50, under 10 ms at p99. - Real-time sequencer failover and replication. - Flexible exchange logic implementation (either in Rust or EVM), depending on developer preference. If that sounds interesting to you, lets talk.
