Verification layer for agents opens
navaai, backed by $8.3M in funding, opened a testnet waitlist for a verification layer aimed at autonomous agents and is offering free tester rewards to early participants. The project targets trust and attestation for agents that act across tools and services. (x.com)
Nava has opened a private testnet waitlist for software that checks an artificial intelligence agent’s actions before money moves. (navalabs.ai) The company said its verification layer sits between an agent’s decision and onchain execution, and blocks transactions that fail checks for intent alignment, protocol safety, parameter validity, or adversarial inputs. (navalabs.ai) Nava disclosed an $8.3 million seed round on April 14, 2026, with Polychain and Archetype co-leading the financing. Fortune reported the startup is led by chief executive Vyas Krishnan and co-founder Brianna Montgomery, who previously worked together at EigenLayer. (finance.yahoo.com) A verification layer is a checkpoint for agents, like a fraud screen for a credit-card payment. Nava said its system breaks a proposed transaction into a graph of checks, records the results, and posts the reasoning trail onchain before execution. (navalabs.ai) That pitch lands as more companies push machine payments and agent-led commerce. Fortune said Coinbase’s x402 standard and Stripe-backed Tempo’s Machine Payments Protocol are early efforts to let agents transact across the web. (finance.yahoo.com) The standards side of that work is also taking shape. A June 2025 Internet Engineering Task Force draft proposed new Entity Attestation Token extensions so agentic systems can make signed claims about capabilities, policies, and operating constraints. (ietf.org) Nava said its first test release will include the Arbiter verification engine, support for Uniswap policies, software development kits in TypeScript and Python, agent registration gated by application programming interface keys, and testnet transaction logging. (navalabs.ai) Fortune reported Nava currently runs as a layer-3 blockchain on Arbitrum and plans a parallel deployment on Tempo. The same report said Nava uses escrow so funds stay locked unless a proposed transaction passes verification. (finance.yahoo.com) The waitlist page describes the rollout as an invite-only, incentivized testnet, with invites releasing daily for what it calls “verifiable AI-powered fund workflows.” Nava’s blog says the private testnet is now open to builders seeking early access. (testnet.knidos.xyz) (navalabs.ai) Nava’s wager is that agent payments will need the same thing human payments already do: a system that can prove what was supposed to happen before anyone lets funds leave escrow.
