Numix presented the Diamond Proxy Standard for Soroban, enabling upgradable smart contracts with shared storage. This allows asset managers to deploy on-chain without immutability constraints, addressing regulatory compliance needs for real-world asset tokenization on Stellar.
Numix introduced a Diamond Proxy Standard implementation for Soroban that solves the immutability problem for enterprise adoption. The pattern uses facets (modular smart contracts) pointing to shared storage, allowing upgrades without data migration or redeployment. Key features include the diamond factory for deployment, loop introspection for monitoring, and XDR-serialized shared storage access. The team demonstrated a KYC compliance application and Numix ID framework for digital identities. While adding deployment overhead, the pattern enables complex, upgradable systems critical for real-world asset tokenization where regulatory changes and bug fixes are inevitable.
