Flowra, an open order flow auction and validator infrastructure platform for Solana, has announced a collaboration with compliance provider Honeypot to integrate sanctions and risk screening directly into the Solana block-building process. The integration is designed to give institutional validators configurable tools to define compliance policies before transactions are finalized on-chain.
The collaboration merges Honeypot's compliance intelligence with Flowra's Programmable Block Policy (PBP), allowing validators to set customizable rules governing which transactions and bundles can be included during block construction. Instead of enforcing a single compliance standard across the network, each validator independently decides whether to apply compliance policies and which providers to integrate, matching their operational and regulatory needs.
The initial implementation focuses on sanctions screening, including checks on wallet addresses linked to sanctioned entities, and network-level indicators such as VPNs, proxy services, and Tor exit nodes. Flowra plans to expand the framework to support additional enterprise compliance providers, giving validators flexibility as institutional adoption grows. The system brings compliance into the block-building workflow, rather than relying solely on pre-network controls used by exchanges and custodians.
Flowra CEO Harry Hwang emphasized that validators retain full autonomy: "The goal isn't to make the network less open, it's to give individual validators the flexibility to operate in a way that reflects their own requirements." The partnership initially addresses auditability and wallet screening for regulated institutions, with more technical capabilities expected as development progresses.
