According to @ItsDave_ADA, high-frequency trading on Cardano is possible via Hydra, Cardano’s scaling framework. source: X post by @ItsDave_ADA on Dec 2, 2025 Input Output Global describes Hydra as an isomorphic state-channel framework that processes transactions off-chain among defined participants with fast finality and settles results back to the Cardano L1. source: Input Output Global Hydra documentation IOG further states Hydra is designed to reduce latency and fees for high-throughput interactions by keeping most activity off-chain while preserving on-chain security guarantees. source: Input Output Global Hydra documentation For traders, a DEX integrating Hydra Heads for order matching can provide sub-L1 latency execution within the Head with periodic settlement to L1, aligning with the author’s HFT claim. source: Input Output Global Hydra documentation; X post by @ItsDave_ADA on Dec 2, 2025
