The architecture merges NYSE's advanced Pillar matching engine with blockchain-based post-trade infrastructure. What's notable here is the multi-chain settlement and custody support—essentially bridging institutional-grade trading systems with on-chain flexibility. This kind of hybrid model matters because it addresses a key pain point: how traditional high-speed trading mechanics can coexist with blockchain's distributed settlement capabilities. The technical bridge between centralized execution and decentralized settlement opens interesting possibilities for both institutional adoption and market infrastructure evolution.
