# RAIL Token Overview RAIL is the RAILGUN Protocol's security token. Holding RAIL is not necessary to use the privacy system nor does holding RAIL provide privacy. RAIL is a standard ERC-20 token deployed to Ethereum. RAIL liquidity can be found on Sushiswap and Uniswap, with aggregated routing available through [Matcha.](https://matcha.xyz/)​ ​[Stake RAIL](https://governance.railgun.org) to secure the protocol and collect security rewards. RAILGUN on Polygon and BSC have their own independent governance systems & tokens which are separate from the system on Ethereum. RAILGUN on Arbitrum is secured by staked RAIL on Ethereum. ### Contract Addresses **Ethereum - RAIL**: 0xe76c6c83af64e4c60245d8c7de953df673a7a33d **BNB Smart Chain - RAILBSC:** 0x3F847b01d4d498a293e3197B186356039eCd737F **Polygon - RAILPOLY:** 0x92A9C92C215092720C731c96D4Ff508c831a714f --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
