Vanar, an Artificial Intelligence (AI-native) blockchain infrastructure platform focused on building systems and intelligent applications to operate securely and transparently, is pleased to launch xBPP, a new open protocol built to govern autonomous AI agent behavior before transactions reach payment rails. The main purpose of this launch is to supervise AI agent decisions for payment rails. This will allow or block the proceeding.
xBPP released under the Apache 2.0 license, the Execution Boundary Permission Protocol is ready as an open standard that any developer, company, or platform can implement directly by themselves without requiring permission from Vanar. Currently, AI agents are developed enough to run transactions completely by themselves, but this infrastructure monitors those transactions at the initial stages before going to the execution phase.
xBPP Governs AI-Driven Transactions with Pre-Execution Policy Control
xBPP acts as a policy layer that determines whether transaction actions are proceedable or not. This system also ensures the authenticity of the source and then allows AI agents to do the action. Basically, xBPP is purposefully built to address the point.
Vanar openly elaborates its specification that it is much more advanced than traditional systems and Agent Policy Infrastructure, which can only execute, but this system ensures the autonomous system is allowed to proceed or hold. The engineers of autonomous payment systems explored that the present infrastructure could authorize and take out transactions; there is a lack of a standard pathway to emphasize policy decisions ahead of execution.
In the past, various companies had laid the groundwork for agent-driven commerce, such as Google’s AP2, which provides a protocol for agent payment, x402 enables HTTP-native payments between software and services, Agentic Commerce Protocol (ACP) helps agent-ready commerce flow, and MasterCard’s Verifiable Intent comes with a trusted layer for agentic commerce. These firms make sure agents can authorize and execute transactions.
Vanar’s Framework for Pre-Execution Policy Control in Autonomous Systems
Vanar’s launched xBPP examines every proposed action against externally defined governance policies. The starting release includes a 1760-line specification built around a framed nine-phase evaluation pipeline covering validation, risk checks, corresponding party verification, escalation triggers, and final decision logic. The protocol also explains 67 standardized motive codes to define outcomes and support auditable records.
xBPP can return one of three deterministic outcomes, such as ALLOW, BLOCK, or ESCALATE, at the time of the proposed transaction. Jawad Ashraf, CEO of Vanar, said, “Many of the building blocks for agentic commerce are now in place, but policy enforcement has remained an open problem.
Before any business gives autonomous systems authority over payments or service access, it needs a reliable way to define boundaries and apply them consistently. It also needs a clear record of why a decision was made.
xBPP was built to provide that control layer. It gives developers and enterprises a framework for enforcing decisions before execution, documenting outcomes, and expanding autonomy with the right safeguards in place.” xBPP is sketched to praise the emerging agentic commerce stack. In that stack, the authorization protocol assures user consent.
