Flowra, an orderflow auction and validator infrastructure platform for Solana, has partnered with compliance infrastructure provider Honeypot to integrate sanctions and risk screening into the block-building process.
According to the companies, the collaboration combines Honeypot’s compliance tools with Flowra’s Programmable Block Policy (PBP), allowing validators to define rules governing which transactions and bundles can be included during block construction.
The integration is designed to support sanctions screening, including checks for wallet addresses linked to sanctioned entities, as well as network-level indicators such as VPNs, proxy services, and Tor exit nodes.
The companies said the framework is also intended to support additional enterprise compliance providers over time.
“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.”
Under the model, each validator can set its own compliance policy, allowing operators to determine how transactions are screened while retaining control over block-building decisions.
The initial rollout will focus on sanctions screening, wallet screening, and auditability for regulated institutions, with additional technical details to be released as implementation progresses.
