Flowra Integrates Sanctions Screening into Solana Block Building

Flowra, an open order flow auction and validator infrastructure platform for Solana, has partnered with compliance infrastructure provider Honeypot to integrate sanctions and risk screening into the network's block-building process. This collaboration combines Honeypot's compliance intelligence with Flowra's Programmable Block Policy (PBP) framework.

Validators will be able to configure screening policies based on sanctions-related criteria, including wallet addresses associated with sanctioned entities. The system is also designed to evaluate network-level indicators linked to transaction origin, such as the use of virtual private networks (VPNs), proxy services and Tor exit nodes.

According to Flowra, these methods account for an estimated 31% to 61% of traffic that reaches blockchain infrastructure through network obfuscation techniques. The integration aims to support institutional validators seeking greater control over compliance while participating in blockchain validation.
