In the Solana ecosystem, putting security capabilities into practice and getting users to keep using them are two different challenges. According to a report by Jinse Finance on October 28, 2026, Google’s MPC crypto custody service is still in private preview, with several institutions testing it and commercial launch planned for early 2027. Alphabet has already used it to protect digital assets on Ethereum and Solana. This is progress in institutional custody—not the launch of an application for ordinary users, and certainly not evidence that the entire ecosystem is adopting it at once.
MPC splits private keys into multiple shares and stores them separately; before signing, transactions must also pass checks against rules set by the institution. For institutions, this may offer a key-management solution. But a service still in testing is some distance from commercial availability, and its pricing has not been disclosed. Existing reports offer no answer as to whether it will improve specific workflows or lead to sustained use. Safer custody does not mean smoother access to on-chain trading, nor does it mean aggregation and liquidity have already improved.
Rolling 24 hours: $SOL +0.57%. Rolling 24 hours: $JUP +0.00%. Rolling 24 hours: $RAY -4.03%. These are the respective changes in three spot quotes, not proof of institutional testing progress or ecosystem usage. Access, aggregation, liquidity, and custody each address different parts of the process. I’d rather see evidence of actual usage after the service officially launches before deciding whether it really helps users solve a problem.
