Nava, a startup building trust infrastructure for AI agents that execute financial transactions autonomously, closed an $8.3 million seed round co-led by Polychain and Archetype, Fortune reported on April 14.
The funding targets a specific gap in the emerging agentic commerce stack: verification that an AI agent’s proposed transaction actually matches the user’s intent before real money moves.
How Nava’s Escrow System Works
Nava operates as an escrow layer between the user’s funds and the agent’s actions. When an AI agent proposes a transaction, the funds are held until Nava’s verification framework determines whether the expected outcome matches the user’s stated intent. If the check passes, the transaction executes. If not, funds stay in escrow, according to Fortune.
The reasoning behind each accept or reject decision is posted on-chain, creating a public audit trail that other AI systems can reference. Nava currently runs as a layer 3 blockchain built on Arbitrum, with a parallel deployment planned on Stripe-backed Tempo, CEO Vyas Krishnan told Fortune.
Agentic Commerce Context
Nava enters a market that several larger players have begun to define. Coinbase launched x402, a standard for AI agents to transact across the web. Stripe-backed Tempo introduced the Machine Payments Protocol for AI payment flows. Those projects focus on enabling agent transactions. Nava’s bet is that enabling transactions without a verification layer will not be enough, as enterprises and consumers need safety guarantees before letting agents manage real capital.
“Consumers are going to want to be able to protect assets from agent misbehavior, agent hallucination, but then institutions aren’t going to be able to onboard unless they have some sort of clarity of intent versus execution,” Krishnan told Fortune.
Team and Backers
Krishnan and cofounder Brianna Montgomery previously worked together at EigenLayer, an Ethereum-focused startup. EigenLayer founder Sreeram Kannan is among the investors in the round, per Fortune.
Nava’s white paper outlines a longer-term vision where the verification layer enables AI agent insurance markets to emerge, with a planned native stablecoin for “underwriting agent action through the protocol.”
The Trust Gap in Autonomous Finance
The funding comes as enterprises scale agent deployments into financial workflows. EY recently announced production agentic AI across 130,000 auditors globally. Charles Schwab confirmed client-facing AI agents launching in June 2026. Aurionpro launched an AI-native trade finance platform with a confidence-gated handoff protocol. Each of these deployments faces the same question Nava is trying to answer: how do you verify that an agent’s financial action matches what the human actually wanted?
At $8.3 million, Nava is small. The question is whether dedicated trust infrastructure becomes a standalone category or gets absorbed into the payment rails themselves as Coinbase, Stripe, and the major platforms build out their own agent commerce stacks.
