Functions

func AllInvariants

func AllInvariants(k Keeper) sdk.Invariant

AllInvariants runs all invariants of the stakeibc module

func ClaimCallback

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

ICA Callback after claiming unbonded tokens

If successful:
   * Removes the user redemption record
If timeout/failure:
   * Reverts pending flag in the user redemption record so the claim can be re-tried

func DelegateCallback

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

ICA Callback after delegating deposit records

  If successful:
     * Updates deposit record status and records delegation changes on the host zone and validators
  If timeout:
     * Does nothing
  If failure:
		* Reverts deposit record status

func DelegatorSharesCallback

func DelegatorSharesCallback(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 exchange rate
  2. the Delegation ICA's delegated shares And apply the following equation: num_tokens = exchange_rate * num_shares

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 GetValidatorFromAddress

func GetValidatorFromAddress(validators []*types.Validator, address string) (val types.Validator, index int64, found bool)

Get a validator and its index from a list of validators, by address

     * Does nothing
  If failure:
		* Reverts epoch unbonding record status

This is the callback from query #1

func WithdrawalBalanceCallback

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

WithdrawalBalanceCallback is a callback handler for WithdrawalBalance queries. The query response will return the withdrawal account balance If the balance is non-zero, ICA MsgSends are submitted to transfer from the withdrawal account

to the delegation account (for reinvestment) and fee account (for commission)

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"
