Solana privacy protocol runs $120 million in 100 days, with a single-day peak reaching $4 million

[Crypto World] A protocol dedicated to privacy transfers has emerged on Solana—Privacy Cash, which uses zero-knowledge proof technology to encrypt SOL transactions. It launched at the end of August last year, and in less than 100 days, over 680,000 SOL have been processed, which is roughly $121 million at current prices.

At its peak, daily volume reached 32,500 SOL, equivalent to over $4 million. Now, it stabilizes at around $12.3 million per week. The user profile is quite clear: more than 17,000 wallets have contributed over 60,000 transactions, with the main funds concentrated in the $100–$1,000 range—clearly retail-driven, but with high frequency.

The protocol itself has earned $240,000 in fees. In November last year, they began testing private USDC transfers; currently, the TVL is just over $620,000, so the scale isn’t huge yet. However, judging by the growth curve, there is indeed a group of users on Solana seeking privacy transaction solutions—there is clear demand in this sector.
