- Railgun has processed $1.6 billion in private transactions in 2025.
- This brings its total transaction volume to $4 billion since 2021.
- Railgun recently integrated into a new Ethereum developer toolkit called Kohaku.
- The Ethereum Foundation launched a privacy initiative to make private transactions a standard feature.
- Railgun’s team released a prototype privacy multi-signature wallet, planned for demo at Devconnect Argentina.
Railgun, a privacy protocol for cryptocurrency transactions, processed $1.6 billion in shielded transactions this year. Since its launch in 2021, it has handled a total of $4 billion in private transfers. This development comes amid increased interest in privacy features for blockchain transactions.
The surge occurred alongside a nearly 300% rise in the value of Railgun’s governance token, RAIL, after the Ethereum Foundation introduced Kohaku, a new developer toolkit integrating Railgun into Ethereum’s primary wallet framework. Railgun’s shielded transactions hide details like senders, recipients, and amounts, unlike standard Ethereum transactions that are public.
Bill Liang, a contributor to Railgun, said, “Privacy is in every financial system except for DeFi,” highlighting the need for confidentiality in decentralized finance. He added, “Even something as simple as transferring value between accounts on a public ledger forces you to reveal your hand when you may not be ready to do so.”
The Ethereum Foundation is advancing privacy through its 47-member “Privacy Cluster,” focusing on making private transactions common on the network. The foundation stated, “Privacy is the freedom to choose what you share, when you share it, and who you share it with.” Ethereum co-founder Vitalik Buterin supports privacy tools like Railgun and encouraged developers last month to add multi-signature privacy wallets, a feature used by institutions but missing from current privacy protocols.
In response, Railgun’s team unveiled a working prototype of a privacy-focused multi-signature wallet that keeps wallet controllers anonymous using zero-knowledge technology, the same method behind its shielded transactions. The team plans to demonstrate this tool at Devconnect Argentina next month.
Jan Philipp Fritsche, managing director at crypto auditing firm Oak Security, said, “Ethereum’s commitment to privacy will accelerate its momentum in becoming the new economic layer for the internet.”
