# RAIL Token Overview

What the RAIL token is for (security staking and protocol requests) and isn't (gas fees, buybacks, burns).

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://stakerail.fi) to secure the protocol and collect security rewards. stakerail.fi is a security staking portal run by a third party, not the RAILGUN protocol team. See [Helpful Links](/wiki/learn/helpful-links.md) to verify contract addresses directly, or interact with the staking contracts yourself.

RAILGUN on Polygon and BSC have their own independent security-staking systems & tokens which are separate from the system on Ethereum.

RAILGUN on Arbitrum is secured by staked RAIL on Ethereum.

**Note:** RAIL is never used to pay transaction or gas fees. Those are paid in the token being transacted, or in the chain's native gas. There is no "RAIL guardian" role, and no buy-back-or-burn mechanism. RAIL, RAILPOLY, and RAILBSC are fixed-supply ERC-20s.
