Liquidity Mining

Stake LP Tokens. Earn 15% of protocol incentive fees collected.
Liquidity Mining pools are used to incentivize LP token holders to deposit their liquidity so their community can bridge between the supported chains of the Cross-Chain Bridge and their project. Liquidity Mining Pools are an easy and passive way for projects with bridging needs to earn yield by adding additional utility to their token. Furthermore, Liquidity Mining pools incentivize community members to provide liquidity as they too can earn rewards every time their token is bridged. For projects, this resembles something like "Staking" offered to their communities.
Important: LP Tokens do not earn rewards automatically, they have to be put in either a Liquidity Mining Pool.
LP Tokens that are deposited in their corresponding Liquidity Mining pool earn rewards in the form of the token that they're providing liquidity for. The rewards, or APRs, are 15% of the protocol incentive or bridging fees. These fees are divided among the Liquidity providers in their given pool.
Examples: If you provide USDC liquidity on Ethereum via Manage Liquidity, you'll receive USDC LP tokens. You must deposit your USDC LP tokens in the corresponding USDC Liquidity Mining Pool on Ethereum to earn your share of Protocol Incentives each time USDC is bridged to Ethereum. The more people bridge the asset you provide liquidity for, the higher your APR (assuming your share in the Liquidity Mining Pool stays constant).
The rewards per user will be determined by a) The collected protocol incentive or bridging fees, respectively (and thus the bridging volume in the asset of the Liquidity Mining Pool), and b) The user's share of the pool - which is:
Liquidity Mining Pool Share =
User Amount of LP Tokens in Pool / Total Amount of LP Tokens in Pool
The APR of Liquidity Mining Pools shown on the website is an estimate and average calculated by using the current staking amount and bridging volume from the last 7 days (except for the initial days after a new token listing when no 7-day history is available. In this case, the longest available period between 24 hours and 7 days is taken). The actual Rewards depend on the amount staked as well as the size & amount of bridgings that occur in the future. The more of each, the higher the collected protocol incentive or bridging fees, and the higher the rewards. The fees dedicated to Liquidity Mining Pools will be randomly sent roughly every second day (if a transaction occurs).
Most new assets that get self-listed (or whitelisted by the team) generate a Liquidity Mining pool.
