Types

type Keeper

type Keeper struct {
	// contains filtered or unexported fields
}

func NewKeeper

func NewKeeper(store cdtkeeper.Int64Store) Keeper

NewKeeper creates a new keeper instance

func (Keeper) Allowance

func (k Keeper) Allowance(ctx sdk.Context, owner string, spender string) (int64, error)

Allowance Returns the remaining number of tokens that `spender` will be allowed to spend on behalf of `owner` through {transferFrom}. This is zero by default.

func (Keeper) Approve

func (k Keeper) Approve(ctx sdk.Context, owner string, spender string, amount int64) (err error)

Approve sets `amount` as the allowance of `spender` over the caller's tokens.

func (Keeper) BalanceOf

func (k Keeper) BalanceOf(ctx sdk.Context, account string) (int64, error)

BalanceOf returns the amount of tokens owned by `account`.

func (Keeper) Burn

func (k Keeper) Burn(ctx sdk.Context, account string, amount int64) error

Burn Destroys `amount` tokens from `account`, reducing the total supply.

func (Keeper) ExportGenesis

func (k Keeper) ExportGenesis(ctx sdk.Context) *types.GenesisState

ExportGenesis exports bridge module's portID and denom trace info into its genesis state.

func (Keeper) InitGenesis

func (k Keeper) InitGenesis(ctx sdk.Context, state types.GenesisState)

InitGenesis initializes the bridge module state and binds to PortID.

func (Keeper) Mint

func (k Keeper) Mint(ctx sdk.Context, account string, amount int64) error

Mint creates `amount` tokens and assigns them to `account`, increasing the total supply.

func (Keeper) TotalSupply

func (k Keeper) TotalSupply(ctx sdk.Context) (int64, error)

TotalSupply returns the amount of tokens in existence.

func (Keeper) Transfer

func (k Keeper) Transfer(ctx sdk.Context, spender, recipient string, amount int64) error

Transfer moves `amount` of tokens from `sender` to `recipient`.

func (Keeper) TransferFrom

func (k Keeper) TransferFrom(ctx sdk.Context, owner string, spender string, recipient string, amount int64) error

TransferFrom moves `amount` tokens from `sender` to `recipient` using the allowance mechanism. `amount` is then deducted from the caller's allowance.
