BlockBeats News, April 14th, according to Fortune magazine, cryptocurrency startup Nava has completed an $8.3 million seed round financing to build a "trust layer" in its autonomous payment system. The round was led by venture capital firms Polychain Capital and Archetype.

Nava CEO and co-founder Vyas Krishnan said in an interview: "As more and more of these tools come to market, these agents will naturally and autonomously start executing transactions, creating transactions, and managing economic activity. We hope to position ourselves as a trusted system handling real funds in financial workflows."

Nava's core solution to constrain AI agent "misbehavior" is to establish a custody system: funds will be temporarily locked up before the agent proposes a transaction. After the agent proposes a transaction, Nava will use a verification framework to determine if the transaction outcome aligns with user intent. If validated, the transaction will be executed; if not, the funds will remain in the custody account.

Nava records and publishes the decision logic for each transaction's approval or rejection on-chain, creating a public ledger of decisions for other AI systems to reference. Currently, Nava operates as a Layer 3 blockchain built on Arbitrum, and the system will also see parallel deployment on Tempo, Krishnan noted. In the long term, Nava's validation layer for autonomous commerce could create the necessary conditions for an AI agent insurance market to emerge, as outlined in the project's whitepaper. Nava also plans to introduce a native stablecoin for "underwriting agent behavior through the protocol."
