# Liquidity

Contribute liquidity to earn yield. Yield comes in the form of trading fees of the underlying Liquidity Pool (LP), as well as in Backprop Subnet Tokens from emissions of the Backprop Subnet, which can be further locked to receive Backprop Finance protocol fees and bribes. More infomation regarding the bribes can be found [here](/backprop-finance-for-dex/bribe.md) while the mechanism of Backprop Subnet can be found in [here](/backprop-subnet/intro.md).

## Add Liquidity to an Existing Pool

Users can obtain LP tokens for TAO/EVM pools without using bridges. We will also provide zapping functionalities that supports single or multiple tokens, so that users can easily consolidate their TAO/EVM positions and earn yield by contributing liquidity.&#x20;

## Create New Pool

Users can easily create a new pool and the associated gauge to facilitate trading with deep liquidity. Gauge is used to store and channel the emissions not only from Backprop Subnet, but also from additional external protocol tokens the Pool Creator used to incentivise liquidity.
