Flowra today announced a collaboration with compliance infrastructure provider Honeypot to introduce validator-level sanctions and risk screening for Solana, extending compliance capabilities into the block-building process through Flowra’s Programmable Block Policy framework.
The collaboration enables institutional validators to define customizable policies governing which transactions and bundles can be included during block construction. By combining Honeypot’s compliance intelligence with Flowra’s validator infrastructure, the companies aim to provide regulated operators with additional tools to meet compliance requirements while maintaining independent control over how those policies are implemented.
The initial rollout supports screening against sanctions-related criteria, including wallet addresses associated with sanctioned entities, as well as network-level indicators such as VPNs, proxy services and Tor exit nodes. Flowra said the architecture is designed to support additional enterprise compliance providers over time, allowing validators to integrate different compliance solutions as regulatory expectations and institutional participation continue to evolve.
Institutional adoption has expanded beyond trading platforms and custodians to include staking providers, infrastructure operators and professional validators. As those participants become a larger part of blockchain ecosystems, many are looking for infrastructure that can accommodate compliance requirements without requiring every validator on the network to operate under the same rules.
Flowra’s approach is designed around validator choice rather than network-wide enforcement. Each validator can independently determine whether compliance policies are implemented, which providers are integrated and how transaction selection rules are configured. That flexibility allows regulated operators to adapt their infrastructure to their own operational or jurisdictional requirements while preserving the decentralized nature of validator participation across the network.
Unlike compliance controls applied before transactions reach the blockchain, the collaboration introduces configurable policies within the validator workflow itself. Validators that choose to participate can evaluate transactions and bundles during block construction according to policies they define, while validators that do not require those controls can continue operating under their existing workflows.
“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 companies said the collaboration will initially focus on sanctions screening, wallet screening and auditability for regulated institutions. Additional technical capabilities and integrations are expected to be introduced as implementation progresses, expanding the number of enterprise compliance providers available through Flowra’s Programmable Block Policy framework.
Flowra builds validator infrastructure, delegation programs and orderflow technologies for the Solana ecosystem with a focus on improving transparency, incentive alignment and value distribution across network participants. Honeypot provides compliance intelligence that enables exchanges, DeFi protocols and financial institutions to detect VPNs, proxy services, Tor exit nodes and other forms of location obfuscation while supporting sanctions compliance and regulatory audit requirements.
