📌 Executive Summary

The Prop Trust Verified Standard (PTVS v1.0) addresses the critical Physical Oracle Gap in Real World Asset (RWA) tokenization. While traditional cryptographic oracles deliver reliable data feeds for liquid on-chain assets, physical real estate assets require legally binding, deterministic verification regarding structural integrity, pathology, and legal title prior to minting or yield distribution.

PTVS bridges off-chain forensic judicial audits—conducted under the Spanish Civil Procedure Act (Ley de Enjuiciamiento Civil – LEC) and authenticated with eIDAS-qualified electronic signatures—directly into ERC-3643 / ONCHAINID permissioned tokenized ecosystems.
