      Enforces a policy ladder for Solana AI agents so on-chain actions are vetted before signing, checking whether an action is justified, recently repeated, or targets only known programs, and applying spend, daily, and slippage caps plus recipient allowlists. Also dry-runs candidate transactions on an RPC and exposes the policy rules as agent prompt instructions.

      Enables AI agents to score Solana tokens, simulate and decode transactions, and apply owner-defined limits, allowlists and slippage rules before anything is signed, returning a clear allow, confirm, block or freeze verdict. Also supports on-chain enforcement through a Squads multisig so an agent can propose trades but only execute when the gateway approves, with a kill-switch and owner approval flows for risky actions.

      Enables AI agents to propose wallet payments while a local, human-authored policy decides whether each transaction is approved, requires human confirmation, or is refused, and records every decision in a signed, append-only ledger.
