trueGold Consortium Pty Ltd, a subsidiary of SMX (Security Matters) PLC, is transforming the gold industry by introducing a groundbreaking chemical marking technology. This innovation enables a fully traceable and verifiable supply chain for gold, from mining to marketplace and recycling. The process involves adding an invisible marker at the mine-site, recording every transfer on a secure digital ledger, and allowing for instant verification throughout the metal's lifecycle. This results in unprecedented transparency and accountability, empowering brands to meet stringent ethical sourcing standards. The SMX technology captures the entire journey of the finished gold product, providing brands with an authentic story and consumers with confidence in an ethically sourced supply chain. Recent tests confirm that SMX's markers are chemically inert, non-toxic, and do not affect the metal's purity or skin compatibility, ensuring robust traceability alongside high consumer safety and product quality standards.
