Flowra and Honeypot Partner to Bring Sanctions Screening Directly to Solana Block Building

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

The collaboration combines Honeypot’s compliance intelligence with Flowra’s Programmable Block Policy (PBP), enabling validators to define compliance rules governing which transactions and bundles can be included during block construction. Rather than applying a single policy across the network, each validator can independently determine how compliance policies are implemented based on its own operational or regulatory requirements.

The integration is initially designed to support sanctions-related screening, including wallet addresses associated with sanctioned entities, as well as network-level indicators such as VPNs, proxy services and Tor exit nodes. The framework has also been designed to support additional enterprise compliance providers over time, allowing validators to incorporate different compliance solutions as institutional requirements evolve.

As blockchain infrastructure attracts greater participation from regulated financial institutions, validators are increasingly expected to operate within compliance frameworks while continuing to support decentralized networks. Flowra’s Programmable Block Policy is designed to give validators greater flexibility over transaction selection without requiring network-wide enforcement or reducing validator autonomy.

“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 focus on sanctions screening, wallet screening and auditability for regulated institutions, with additional technical capabilities expected as implementation progresses.
