Railgun FAQs
What is Railgun?
Railgun is a smart-contract privacy system that uses zk-SNARKs for DeFi activity. It is described as supporting private DEX trading, lending and other on-chain interactions.
Which chains does Railgun support?
Railgun is listed on Ethereum, Arbitrum, BNB Chain and Polygon. Check that the specific app or wallet you plan to use supports your chosen network before sending funds.
What does Railgun cost, and is it safe?
Railgun does not publish fee details in the information reviewed here, so you should check the app’s current transaction costs before using it. Two audits are listed, but that alone does not establish the scope or status of those audits, or whether funds are held in custody.
