Functions

func AccumulationStoreInvariant

func AccumulationStoreInvariant(keeper Keeper) sdk.Invariant

AccumulationStoreInvariant ensures that the sum of all lockups at a given duration is equal to the value stored within the accumulation store.

func MergeLockupsForSimilarDurations

func MergeLockupsForSimilarDurations(
	ctx sdk.Context,
	k Keeper,
	ak types.AccountKeeper,
	baselineDurations []time.Duration,
	durationDiff time.Duration,
)

MergeLockupsForSimilarDurations iterates through every account. For each account, it combines all lockups it has at a similar duration (to be defined in a bit). It will delete every existing lockup for that account, and make at most, a single new lockup per "base duration", denom pair. If a lockup is far from any base duration, we don't change anything about it. We define a lockup length as a "Similar duration to base duration D", if: D <= lockup length <= D + durationDiff.

func RegisterInvariants

func RegisterInvariants(ir sdk.InvariantRegistry, keeper Keeper)

Types

type AdminKeeper

type AdminKeeper struct {
	Keeper
}

AdminKeeper defines a god privilege keeper functions to remove tokens from locks and create new locks For the governance system of token pools, we want a "ragequit" feature So governance changes will take 1 week to go into effect During that time, people can choose to "ragequit" which means they would leave the original pool and form a new pool with the old parameters but if they still had 2 months of lockup left, their liquidity still needs to be 2 month lockup-ed, just in the new pool And we need to replace their pool1 LP tokens with pool2 LP tokens with the same lock duration and end time.
