Flowra, an open orderflow auction and validator infrastructure platform for Solana, has announced a collaboration with compliance infrastructure provider Honeypot to integrate sanctions and risk screening into the network's block-building process.
The partnership combines Honeypot's compliance intelligence with Flowra's Programmable Block Policy (PBP) framework, allowing validators to establish customizable rules that determine which transactions and bundles are eligible for inclusion in newly constructed blocks.
According to the companies, the integration is aimed at institutional validators seeking greater control over compliance while participating in blockchain validation.
Bringing compliance into block construction
Traditionally, blockchain compliance tools have focused on monitoring activity after transactions are processed or assisting businesses that interact with blockchain networks.
Flowra's approach moves part of that process earlier in the transaction lifecycle by allowing validators to evaluate transactions before they are included on-chain.
Under the integration, validators will be able to configure screening policies based on sanctions-related criteria, including wallet addresses associated with sanctioned entities.
The framework 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.
Beyond Honeypot's initial capabilities, the system is intended to support additional enterprise compliance providers as the platform evolves.
Validator autonomy remains central
Rather than imposing a single compliance standard across the network, Flowra said each validator will remain responsible for defining its own policies.
This allows operators to tailor compliance requirements according to their individual regulatory obligations, business models or institutional risk frameworks while preserving the decentralized nature of validator participation.
"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 first phase of the collaboration will concentrate on three core areas:
- Sanctions screening for blockchain wallet addresses.
- Wallet risk assessment and screening.
- Auditability features designed to support regulated institutions.
The companies said additional technical details will be released as implementation progresses.
Institutional adoption drives nfrastructure changes
The announcement reflects a broader trend across the blockchain industry as infrastructure providers develop tools aimed at institutional participants operating under regulatory requirements.
As traditional financial institutions, custodians and regulated service providers increase their involvement in public blockchain networks, demand has grown for infrastructure capable of supporting compliance obligations without fundamentally changing the decentralized architecture of the underlying protocols.
By integrating compliance checks directly into the block-building process, Flowra is positioning its validator infrastructure to accommodate operators that require additional controls while leaving policy decisions in the hands of individual validators.
The collaboration with Honeypot represents another example of blockchain infrastructure evolving beyond transaction execution alone to include governance, compliance and risk management capabilities designed for institutional participation.
