Why is Railgun Surging?

Railgun’s success aligns with explosive growth across the wider privacy coin market. Privacy coins have emerged as one of 2025’s best-performing crypto sectors, outperforming Bitcoin and Ethereum.

Altcoins like Zcash (ZEC) have recorded notable gains and reached multi-year highs, with most of the sector in green over the past week. CoinGecko data revealed that the privacy coin market capitalization has climbed 15% over the past day to reach $12.9 billion. Meanwhile, trading volumes have risen to over $2 billion, reflecting growing investor confidence in privacy-focused assets.

In addition, Railgun has secured support from major figures like Vitalik Buterin. He has repeatedly praised Railgun and even frequently used the protocol.

Railgun’s involvement extends to Kohaku, an SDK for integrating privacy into EVM wallets that the Ethereum Foundation is developing with partners like MetaMask and OKX Wallet. Kohaku natively supports Railgun, potentially boosting its appeal.

“Privacy is a 1000x opportunity in crypto, ZEC’s ascendency is positive proof of the bid for privacy. Institutions & Retail are likely to prefer a solution like Railgun which will likely be integrated into their favorite wallets and allow them to shield their stablecoins, DeFi Positions, etc,” an analyst stated.

He added that Railgun earns revenue with a fixed 0.25% fee on TVL entering or leaving privacy pools. Thus, as more wallets and DeFi platforms shift toward privacy-first strategies, Railgun’s addressable market could expand strongly.
