SmartGold, a U.S. gold IRA provider, has partnered with tokenization platform Chintai to bring $1.6 billion of vaulted gold onchain. This initiative marks the launch of the first tokenized gold solution for self-directed IRAs, allowing investors to tokenize their holdings on a 1:1 basis. The tokenized gold can be used as collateral on DeFi platforms while maintaining tax-deferred status. The service is now live, offering a new avenue for investors to integrate gold into the digital asset ecosystem.
