Saylor Innovations Guide Library
Agent Wallet Spend-Policy Guide. A procedure for bounding what an autonomous agent's wallet can actually do: segregating a dedicated low-balance signer wallet, expressing hard allowlist/cap policy outside the model (network, asset, recipient, per-call and rolling limits), decoding and simulating every transaction against that policy before signing, requiring exact bound approval for high-impact exceptions, and reconciling signature-to-fulfillment.
