Flowra, the open orderflow auction and validator infrastructure platform for Solana, has announced a collaboration with compliance infrastructure provider Honeypot to integrate sanctions and risk screening directly into the Solana block-building process.

The partnership pairs Honeypot's compliance intelligence capabilities with Flowra's Programmable Block Policy (PBP), a framework that allows institutional validators to set compliance rules determining which transactions and bundles may be included during block construction. Each validator retains the ability to define its own policy, preserving validator autonomy while giving operators greater flexibility over block-building decisions.

The integration is designed to support screening against a range of sanctions-related criteria. These include wallet addresses tied to sanctioned entities as well as network-level indicators such as VPNs, proxy services, and Tor exit nodes — methods that account for an estimated 31–61% of traffic arriving through network obfuscation. The framework is also being architected to accommodate additional enterprise compliance providers over time.

The collaboration comes as compliance expectations for blockchain infrastructure operators have intensified since the U.S. Treasury's Office of Foreign Assets Control (OFAC) sanctioned the Tornado Cash mixer in 2022, prompting debate across the industry about the obligations of validators, relayers, and block builders on public networks. On Ethereum, several major infrastructure providers have already adopted transaction-filtering policies at the block-building layer. Solana's high-throughput architecture and growing institutional adoption have made comparable compliance tooling an increasingly relevant priority for regulated participants entering the ecosystem.

"Public blockchains have become increasingly attractive to institutional participants, but the infrastructure hasn't evolved to give validators the compliance controls many regulated operators expect," said Harry Hwang, CEO of Flowra. "We're working with Honeypot to bring compliance into the block-building process itself, allowing validators to define and enforce their own policies before transactions are included on-chain. 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 collaboration will initially concentrate on sanctions screening, wallet screening, and auditability for regulated institutions, with further technical details to be shared as implementation advances.
