Pool Incentives

Abstract

The pool-incentives module is separate but related to the incentives module. When a pool is created using the GAMM module, the pool-incentives module automatically creates individual gauges in the incentives module for every lock duration that exists in that pool. The pool-incentives module also takes the pool_incentives distributed from the gov module and distributes it to the various incentivized gauges.

Concepts

The purpose of the pool incentives module is to distribute incentives to a pool's LPs. This assumes that pool's follow the interface from the x/gamm module

Pool incentives module doesn't directly distribute the rewards to the LPs. When a pool is created, the pool incentives module creates a gauge in the incentives module for every lock duration that exists. Also, the pool incentives module takes a part of the minted inflation from the mint module, and automatically distributes it to the various selected gauges.

State

Genesis states
type GenesisState struct {
 // params defines all the paramaters of the module.
 Params            Params          
 LockableDurations []time.Duration 
 DistrInfo         *DistrInfo      
}

type Params struct {
 // minted_denom is the denomination of the coin expected to be minted
 //  by the minting module.
 // Pool-incentives module doesn’t actually mint the coin itself, 
 // but rather manages the distribution of coins that matches the defined minted_denom.
 MintedDenom string 
 // allocation_ratio defines the proportion of the minted minted_denom 
 // that is to be allocated as pool incentives.
 AllocationRatio github_com_cosmos_cosmos_sdk_types.Dec 
}

Lockable durations can be set to the pool incentives module at genesis. Every time a pool is created, the pool incentives module creates the same amount of 'gauge' as there are lockable durations for the pool.

Also in regards to the Params, when the mint module mints new tokens to the fee collector at Begin Block, the pool incentives module takes the token which matches the 'minted denom' from the fee collector. Tokens are taken according to the 'allocationRatio', and are distributed to each DistrRecord of the DistrInfo. For example, if the fee collector holds 1000uatom and 2000 ufury at Begin Block, and Params' mintedDenom is set to ufury, and AllocationRatio is set to 0.1, 200ufury will be taken from the fee collector and distributed to the DistrRecords.

Gov

Pool Incentives module uses the values set at genesis or values added by chain governance to distribute part of the inflation minted by the mint module to specified gauges.

type DistrInfo struct {
 TotalWeight github_com_cosmos_cosmos_sdk_types.Int 
 Records     []DistrRecord                          
}

type DistrRecord struct {
 GaugeId  uint64                                 
 Weight github_com_cosmos_cosmos_sdk_types.Int 
}

DistrInfo internally manages the DistrRecord and total weight of all DistrRecord. Governance can modify DistrInfo via UpdatePoolIncentivesProposal proposal.

UpdatePoolIncentivesProposal
type UpdatePoolIncentivesProposal struct {
 Title       string       
 Description string      
 Records     []DistrRecord 
}

UpdatePoolIncentivesProposal can be used by governance to update DistrRecords.

merlins tx gov submit-proposal update-pool-incentives [gaugeIds] [weights]

Proposals can be proposed in using the CLI command format above.
For example, to designate 100 weight to gauge id 2 and 200 weight to gauge id 3, the following command can be used.

merlins tx gov submit-proposal update-pool-incentives 2,3 100,200

  "records": [
    {
      "gauge_id": "0",
      "weight": "100000"

  • Pool distribution and lockup infos queries.
  • Distributes incentives to LPs.
