Railgun [RAIL] has achieved a pivotal milestone that could revolutionize privacy for DeFi. The surge in interest around privacy has been evident in token price gains, but many underlying protocols have lacked functionality and scalability—until now.

Previously, users of privacy coins like Zcash and Tornado Cash could deposit and shield their funds from public view or explorers. However, once they wanted to swap assets or utilize lending protocols, they would need to unshield and transfer their funds, making it easy to track their activities. This process left users with little usability beyond just hiding their balances.

Now, Railgun, an Ethereum [ETH]-based project, has successfully tested a feature called Railgun_connect on CowSwap, which enables private wallets to interact with DeFi platforms without requiring users to unshield or move their assets.

According to the project, “RAILGUN_connect is a groundbreaking tool for privacy and marks a significant step toward making private addresses as functional as public ones.” The team has described this feature as a ‘universal plug-and-play’ solution, reducing the complexity previously needed to build integrations for using DeFi applications from private balances.

Railgun utilizes zero-knowledge proofs for secure transfers, ensuring that interactions with DeFi frontends do not compromise either decentralization or user privacy.

Record High Demand for Privacy

There has been an evident surge in interest for DeFi privacy, aligning with Ethereum’s vision and the growing demand for such solutions. The number of shields per day for tracking private wallets has dramatically increased since 2025, reaching an impressive daily average of 326 early in 2026. This robust demand highlights the significant interest in privacy solutions within the DeFi landscape.

Moreover, the total volume processed by the privacy protocol has reached a record $4.5 billion, doubling from $2.4 billion just a year ago. This remarkable growth—almost 100%—illustrates the increasing reliance on privacy in decentralized finance.

The RAIL governance token has not lagged in performance, either. Following a slight pullback earlier in the week, the token rebounded by 25%. This uptick corresponds with a broader rally in privacy coins following the easing of tensions between the U.S. and the E.U., spurred by U.S. President Donald Trump’s pause on tariffs related to a potential Greenland deal.
