**[Cactus Custody Assists OnChain in Bringing CMBI Money Market Fund RWA On-Chain]** BlockBeats News, August 21 — OnChain has partnered with Cactus Custody to tokenize and bring the CMBI USD Money Market Fund on-chain as a Real-World Asset (RWA), providing investors with auditable on-chain investment options. The fund, established on February 2, 2024, ranked first in its category in Bloomberg Asia-Pacific as of July 31, 2025, standing out in the market with its transparency, low volatility, and verifiable net asset value. This collaboration directly addresses four major pain points in on-chain wealth management: - Lack of auditable, custodial cash equivalents on-chain; - Low efficiency in switching funds between banks and on-chain; - Challenges in unifying risk control and audits across multiple jurisdictions; - Fragmented liquidity across multiple chains. OnChain provides RWA on-chain technology services, with net asset value calculated off-chain and periodically uploaded on-chain. Token shareholding and transfers are controlled via whitelists and quotas, while redemption experiences are optimized through proprietary liquidity mechanisms and liquidity contracts. Cactus Custody offers institutional-grade custodial services, employing multi-approval processes, multi-signature mechanisms, cold-hot storage separation, and other multi-layered security measures. These are complemented by daily reconciliations and periodic audits to ensure consistency between accounts and assets, strict segregation of on-chain assets from operational funds, and protection against risks such as hacking or internal errors. This ensures bank-grade investment security for OnChain users, maximizing the protection of user assets from on-chain volatility and external threats. More importantly, this is not just about bringing a fund on-chain but establishing a replicable RWA template. By successfully implementing the full process with a money market fund, the model can later be expanded to include bill pools, short-term debt, and passive products, building a sustainable RWA product line and enriching the on-chain wealth management product ecosystem.
