Features

​
Position NFT

The position state manages unlocked_liquidity + locked_liquidity + vested liquidity. User can interact with the following flows in the same, single position:
  • Permanently lock part of the liquidity
  • Create multiple vesting schedules
  • Add more liquidity (unlocked liquidity)
The Position NFT is also a transferrable NFT that can be sent to other wallets.

​
Farming

For DAMM v2, there is an in-built farming mechanism within the program. This is unlike DAMM v1, where there is a separate farming program. Each specific pool in DAMM v2 can create farming rewards and the pool has its own unique reward vault. Each reward vault can have a maximum of 2 types of reward tokens. When the initialize_reward program endpoint is used, a reward_vault for the specific pool is created, and the initiator can specify the reward token (max 2 types) for the reward_vault Rewards will be shared with all liquidity providers over the farming duration. Currently, in this beta stage:
  1. The initialize_reward program endpoint can only be initialized by Meteora’s admin
  2. Only a whitelisted funder address can fund rewards into this reward_vault
So for now, projects have to reach out to the Meteora team to create a farm and add rewards. We’re exploring ways to make this process permissionless at a later stage.

​
Fee Collection

DAMM v2 pools can collect fees in quote token or output token.

​
Quote Token

  • Swap Quote Token to Base Token, then fees are taken from Quote Token before swap.
  • Swap Base Token to Quote Token, then fees are taken from Quote Token after swap.

​
Output Token

  • Swap Quote Token to Base Token, then fees are taken from Base Token after swap.
  • Swap Base Token to Quote Token, then fees are taken from Quote Token after swap.

​
Min-Max Price

In general, you can set a min-max price range for a balanced pool as DAMM v2 is a constant product AMM that follows a balanced ratio deposit. If you need to set a min-max price range, as well as implement imbalanced deposits for the pool, you need to use DLMM instead.

​
