01
Private balances
Shielded balances are represented inside the privacy system instead of being exposed as a public wallet total.
On-chain ZK Privacy Ecosystem
RAILGUN brings Zero-Knowledge cryptography directly to supported EVM networks, enabling private balances, transfers and smart-contract interactions without leaving the chain.

01 / PRIVACY LAYER
Privacy is not an add-on. It is financial infrastructure.
Public blockchains are verifiable by design, but that can expose balances, counterparties and strategies. ZK systems aim to preserve validity while minimizing disclosure.
02
Private transfers
Zero-knowledge proofs can validate encrypted token transfers without publishing the full financial context.
03
Private DeFi
The architecture is designed for composable smart-contract interactions rather than a single deposit-and-withdraw flow.
04
Non-custodial control
Users interact from self-custodial wallets and retain control of their assets and signing keys.
05
Broadcaster network
Community broadcasters can submit private interactions so a public origin wallet is not required for every action.
06
Developer toolkit
Wallet SDKs and adapt modules give builders a path to add privacy-aware flows to EVM applications.
02 / SYSTEM MAP
A privacy engine that lives directly on-chain.
RAILGUN is described in its official documentation as code deployed on supported EVM networks, with encrypted notes, private balances and ZK proof verification.

RESPONSIBLE PRIVACYPrivacy is not the same as lawlessness.
Privacy technology can have legitimate personal, commercial and civil-society uses. Users remain responsible for applicable laws, sanctions, tax rules and operational security.
No guarantee of absolute anonymity. Timing, amount patterns, reused addresses and network metadata can reduce privacy.
Verify every domain and contract before connecting a wallet or signing a transaction.
Features and supported networks can change. Confirm current details in official documentation.
04 / FAQ
Key questions about RAILGUN
What is RAILGUN?
RAILGUN is an on-chain, non-custodial privacy system that uses Zero-Knowledge cryptography for private balances, transfers and smart-contract interactions on supported EVM networks.
Is RAILGUN the same as Tornado Cash?
No. They are separate protocols with different architectures and user flows.
Which networks are supported?
The current official RAILGUN overview lists Ethereum, BSC, Polygon and Arbitrum. Verify documentation before use because support can change.
