func CalibrateDelegationCallback 

func CalibrateDelegationCallback(k Keeper, ctx sdk.Context, args []byte, query icqtypes.Query) error

DelegatorSharesCallback is a callback handler for UpdateValidatorSharesExchRate queries.

In an attempt to get the ICA's delegation amount on a given validator, we have to query:

  1. the validator's internal shares to tokens rate
  2. the Delegation ICA's delegated shares And apply the following equation: numTokens = numShares * sharesToTokensRate

This is the callback from query #2

Note: for now, to get proofs in your ICQs, you need to query the entire store on the host zone! e.g. "store/bank/key"

func (Keeper) CalculateRewardsSplit 

func (k Keeper) CalculateRewardsSplit(
	ctx sdk.Context,
	hostZone types.HostZone,

) (rewardSplit RewardsSplit, err error)

Breaks down the split of native rewards into the portions intended for (a) a rebate, (b) stride commission, and (c) reinvestment For most host zones, the rewards here were generated from normal staking rewards, but in the case of dYdX, this is called on the rewards that were converted from USDC to DYDX during the trade route

The rebate percentage is determined by: (% of total TVL contributed by commuity pool) * (rebate percentage)

E.g. Community pool liquid staked 1M, TVL is 10M, rebate is 20% Total rewards this epoch are 1000, and the stride fee is 10% => Then the rebate is 1000 rewards * 10% stride fee * (1M / 10M) * 20% rebate = 2 tokens => Stride fee is 1000 rewards * 10% stride fee - 2 rebate = 98 tokens => Reinvestment is 1000 rewards * (100% - 10% stride fee) = 900 tokens

	ctx sdk.Context,
	validator types.Validator,
	previousInternalDelegation sdkmath.Int,
	currentInternalDelegation sdkmath.Int,
) (overlapped bool, err error)

The number of tokens returned from the query must be consistent with the tokens stored in our internal record keeping during this callback, otherwise the comparision between the two is invalidated

As a result, we must avoid a race condition between the ICQ and a delegate, undelegate, redelegate, or detokenization ICA

More specifically, we must avoid the following cases: 

Case 1)
         ICQ Lands on Host                                          ICQ Ack on Stride
                             ICA Lands on Host    ICA Ack on Stride
Case 2)
         ICA Lands on Host                                          ICA Ack on Stride
                             ICQ Lands on Host    ICQ Ack on Stride

We can prevent Case #1 by checking if the delegation total on the validator has changed while the query was in flight

We can prevent Case #2 by checking if the validator has a delegation change in progress

func (Keeper) CheckForSlash 

func (k Keeper) CheckForSlash(
	ctx sdk.Context,
	hostZone types.HostZone,

) (validatorWasSlashed bool, delegatedTokens sdkmath.Int, err error)

Check if a slash occured by comparing the validator's sharesToTokens rate and delegator shares from the query responses (tokens = shares * sharesToTokensRate)

If the change in delegation only differs by a small precision error, it was likely due to an decimal -> int truncation that occurs during unbonding. In this case, still update the validator

If the change in delegation was an increase, the response can't be trusted so an error is thrown

func (Keeper) CheckIfValidatorWasSlashed 

func (k Keeper) CheckIfValidatorWasSlashed(
	ctx sdk.Context,
	hostZone types.HostZone,
	queriedValidator stakingtypes.Validator,
) (validatorWasSlashed bool, err error)

func (Keeper) DetokenizeAllLSMDeposits 

func (k Keeper) DetokenizeAllLSMDeposits(ctx sdk.Context)

Loops through all active host zones, grabs the queued LSMTokenDeposits for that host that are in status DETOKENIZATION_QUEUE, and submits the detokenization ICA for each

func (Keeper) DetokenizeCallback 

func (k Keeper) DetokenizeCallback(ctx sdk.Context, packet channeltypes.Packet, ackResponse *icacallbackstypes.AcknowledgementResponse, args []byte) error

ICACallback after an LSM token is detokenized into native stake 

If successful: Remove the token deposit from the store and incremenet the validator delegation
If failure: flag the deposit as DETOKENIZATION_FAILED
If timeout: do nothing
  - A timeout will force the channel closed, and once the channel is restored,
    the ICA will get resubmitted

func (Keeper) DetokenizeLSMDeposit 

func (k Keeper) DetokenizeLSMDeposit(ctx sdk.Context, hostZone types.HostZone, deposit recordstypes.LSMTokenDeposit) error

Submits an ICA to "Redeem" an LSM Token - meaning converting the token into native stake This function is called in the EndBlocker which means if the ICA submission fails, any modified state is not reverted

The deposit Status is intentionally updated before the ICA is submitted even though it will NOT be reverted if the ICA fails to send. This is because a failure is likely caused by a closed ICA channel, and the status update will prevent the ICA from being continuously re-submitted. When the ICA channel is restored, the deposit status will get reset, and the ICA will be attempted again.

func (Keeper) DisableHubTokenization

func (Keeper) UnbondFromHostZone 

func (k Keeper) UnbondFromHostZone(ctx sdk.Context, hostZone types.HostZone) (err error)

Submits undelegation ICA messages for a given host zone

First, the total unbond amount is determined from the epoch unbonding records Then that unbond amount is allowed to cascade across the validators in order of how proportionally different their current delegations are from the weight implied target delegation, until their capacities have consumed the full amount As a result, unbondings lead to a more balanced distribution of stake across validators

Context: Over time, as LSM Liquid stakes are accepted, the total stake managed by the protocol becomes unbalanced as liquid stakes are not aligned with the validator weights. This is only rebalanced once per unbonding period

  * Burns stTokens
If timeout:
  * Does nothing
If failure:
  * Sets epoch unbonding record status to RETRY

	chainId string,
	epochUnbondingRecordIds []uint64,
	totalNativeTokensUnbonded sdkmath.Int,
	unbondingTime uint64,
) (totalStTokensToBurn sdkmath.Int, err error)

Updates the host zone unbonding records after a successful undelegation batch The StTokensToBurn and the NativeTokensToUnbond amounts on the records are decremented in a cascading fashion starting from the earliest record The latest completion times is also set on each record if the time from the batch is later than what's currently on the record

func (Keeper) UpdateRedemptionRateForHostZone 

func (k Keeper) UpdateRedemptionRateForHostZone(ctx sdk.Context, hostZone types.HostZone, depositRecords []recordstypes.DepositRecord)

func (Keeper) UpdateRedemptionRates 

func (k Keeper) UpdateRedemptionRates(ctx sdk.Context, depositRecords []recordstypes.DepositRecord)

Updates the redemption rate for each host zone At a high level, the redemption rate is equal to the amount of native tokens locked divided by the stTokens in existence. The equation is broken down further into the following sub-components: 

   Native Tokens Locked:
     1. Deposit Account Balance: native tokens deposited from liquid stakes, that are still living on Stride
     2. Undelegated Balance:     native tokens that have been transferred to the host zone, but have not been delegated yet
     3. Tokenized Delegations:   Delegations inherent in LSM Tokens that have not yet been converted to native stake
     4. Native Delegations:      Delegations either from native tokens, or LSM Tokens that have been detokenized
  StToken Amount:
     1. Total Supply of the stToken

Redemption Rate =
(Deposit Account Balance + Undelegated Balance + Tokenized Delegation + Native Delegation) / (stToken Supply)

func (Keeper) ValidateLSMLiquidStake 

func (k Keeper) ValidateLSMLiquidStake(ctx sdk.Context, msg types.MsgLSMLiquidStake) (types.LSMLiquidStake, error)

Validates the parameters supplied with this LSMLiquidStake, including that the denom corresponds with a valid LSM Token and that the user has sufficient balance

This is called once at the beginning of the liquid stake, and is, potentially, called again at the end (if the transaction was asynchronous due to an intermediate slash query)

This function returns the associated host zone and validator along with the initial deposit record

func (Keeper) Validators 

func (k Keeper) Validators(c context.Context, req *types.QueryGetValidatorsRequest) (*types.QueryGetValidatorsResponse, error)

func SortUnbondingCapacityByPriority 

func SortUnbondingCapacityByPriority(validatorUnbondCapacity []ValidatorUnbondCapacity) ([]ValidatorUnbondCapacity, error)

Sort validators by the ratio of the ideal balanced delegation to their current delegation This will sort the validator's by how proportionally unbalanced they are

Ex: 

Val1: Ideal Balanced Delegation 80,  Current Delegation 100 (surplus of 20), Ratio: 0.8
Val2: Ideal Balanced Delegation 480, Current Delegation 500 (surplus of 20), Ratio: 0.96

While both validators have the same net unbalanced delegation, Val2 is proportionally more balanced since the surplus is a smaller percentage of it's overall delegation

This will also sort such that 0-weight validator's will come first as their ideal balanced delegation will always be 0, and thus their ratio will always be 0 If the ratio's are equal, the validator with the larger delegation/capacity will come first

func (*ValidatorUnbondCapacity) GetBalanceRatio 

func (c *ValidatorUnbondCapacity) GetBalanceRatio() (sdk.Dec, error)

The ratio of ideal balanced delegation to the current delegation This represents how proportionally unbalanced each validator is The smaller number means their current delegation is much larger then their fair portion of the current total stake
