Here’s what it looks like to give an AI agent spending limits on @solana. 2 minutes. No complex setup. No private keys inside the agent. Just rules enforced before money moves.

We want Kyvern to become the operating environment for autonomous agents. A place where agents can safely work, transact, and eventually live on-chain. The first step is financial boundaries. Budgets. Policies. Refusals. Consensus before money moves.

A new financial primitive for autonomous agents.

@deantrinheth @solana Exactly. Autonomous spending only matters if autonomous refusal is enforceable and auditable too.

@kyvernlabs @solana Most teams obsess over autonomous spending; the underrated feature is autonomous refusal. If the chain can prove why a payment was denied, you get auditability, not just automation. That is what turns agent finance from a scary demo into something ops and legal can actually ship.

A device for AI agents on Solana. Kyvern gives autonomous agents budgets instead of keys. Every payment is decided by the chain before money moves. In this demo: → Real Solana transactions → A real attack refused on-chain → A third-party agent integrated into Kyvern in four lines Try it yourself, no signup: kyvernlabs.com

AI agents shouldn’t hold keys. They should have budgets.
