The Metaplex Foundation has signed a memorandum of understanding with Crucible Limited to tokenize gold production on the Solana blockchain. This partnership utilizes the recently introduced MPL-3643 token standard, which is designed to support compliant real-world assets and tokenized securities.
Under the proposed structure, a fund managed by Crucible will provide upfront payments for gold extracted from a partner mine. Token holders will receive distributions of tokenized gold as the metal is produced, shifting from static asset tokenization to production-based financing.
The mining partner for this project is KCA, an engineering firm established in 1972 that has constructed over 70 processing plants in more than 30 countries. The MPL-3643 standard allows issuers to embed compliance rules directly into tokens, controlling asset eligibility while maintaining compatibility with Solana wallets.
Metaplex, which originated from Solana Labs in 2021, has facilitated over a billion assets on the network. The foundation launched the alpha version of the MPL-3643 standard between September 29 and October 1, 2026. Another entity, FairClub, also adopted this standard on November 9, 2026, for governance tokens.
