RAILGUN

RAILGUN DAO

3.3/5 5.0/5 · Data verified on

RAILGUN is an onchain privacy system based on zero-knowledge proofs (zk-SNARKs) operating as a smart-contract layer on top of Ethereum, Polygon, BSC and other EVM networks. Users deposit ERC-20 tokens or NFTs into a privacy pool ("shielding") and can then transfer them privately, hiding sender, recipient, amount and token type. It is non-custodial (users always keep their own keys) and governed by the RAILGUN DAO via the RAIL token.

Strengths

  • Non-custodial onchain privacy without leaving the public blockchain: users keep their keys.

  • No notable sovereignty drawback documented.
