RealOpen

RealOpen helps crypto buyers learn how crypto-funded real estate purchases work, verify wallet ownership, check proof-of-funds eligibility, and generate Proof of Funds letters through ChatGPT. This version update adds one read-only knowledge tool (get_started, a static setup checklist for new users), hardens wallet verification server-side (rejects well-known unownable addresses and addresses with publicly known private keys), tolerates pasted-signature whitespace, and clarifies tool descriptions. No permission, OAuth, widget-surface, or data-handling changes; all previously approved tools keep identical annotations and behavior contracts.
