func (k Keeper) GetBalance(
	goCtx context.Context,
	addr sdk.AccAddress,
	denom string,

func (*Keeper) GetRemainderAmount ¶

func (k *Keeper) GetRemainderAmount(
	ctx sdk.Context,
) sdkmath.Int

GetRemainderAmount returns the internal remainder amount.

func (Keeper) GetSupply ¶

func (k Keeper) GetSupply(ctx context.Context, denom string) sdk.Coin

func (*Keeper) GetTotalSumFractionalBalances ¶

func (k *Keeper) GetTotalSumFractionalBalances(ctx sdk.Context) sdkmath.Int

GetTotalSumFractionalBalances returns the sum of all fractional balances.

func (Keeper) IsSendEnabledCoin ¶ added in v0.3.0

func (k Keeper) IsSendEnabledCoin(ctx context.Context, coin sdk.Coin) bool

IsSendEnabledCoin checks whether the sent coin is the extended denom, in which case it also checks for the SendEnabled status on the EVM denom. The rest pass through the regular bank keeper implementation.

func (Keeper) IsSendEnabledCoins ¶

func (k Keeper) IsSendEnabledCoins(ctx context.Context, coins ...sdk.Coin) error

IsSendEnabledCoins uses the parent x/bank keeper to check the coins provided and returns an ErrSendDisabled if any of the coins are not configured for sending. Returns nil if sending is enabled for all provided coin. Note: This method is not used directly by x/evm, but is still required as part of authtypes.BankKeeper. x/evm uses auth methods that require this interface.

func (Keeper) IterateAccountBalances ¶

func (k Keeper) IterateAccountBalances(ctx context.Context, account sdk.AccAddress, cb func(coin sdk.Coin) bool)

func (*Keeper) IterateFractionalBalances ¶

func (k *Keeper) IterateFractionalBalances(
	ctx sdk.Context,
	cb func(address sdk.AccAddress, amount sdkmath.Int) (stop bool),
)

IterateFractionalBalances iterates over all fractional balances in the store and performs a callback function.

func (Keeper) IterateTotalSupply ¶

func (k Keeper) IterateTotalSupply(ctx context.Context, cb func(coin sdk.Coin) bool)

func (Keeper) MintCoins ¶

func (k Keeper) MintCoins(goCtx context.Context, moduleName string, amt sdk.Coins) error

MintCoins creates new coins from thin air and adds it to the module account. If ExtendedCoinDenom is provided, the corresponding fractional amount is added to the module state. It will panic if the module account does not exist or is unauthorized.

func (Keeper) Send ¶ added in v0.3.0

func (k Keeper) Send(goCtx context.Context, msg *banktypes.MsgSend) (*banktypes.MsgSendResponse, error)

Send is a forked Send from the Cosmos SDK x/bank MsgServer, minus the BaseKeeper type validation. ref: https://github.com/cosmos/cosmos-sdk/blob/e265bb9b42308dc70743b6200a70db9aafb70527/x/bank/keeper/msg_server.go#L29

func (Keeper) SendCoins ¶

func (k Keeper) SendCoins(
	goCtx context.Context,
	from, to sdk.AccAddress,
	amt sdk.Coins,
) error

SendCoins transfers amt coins from a sending account to a receiving account. An error is returned upon failure. This handles transfers including ExtendedCoinDenom and supports non-ExtendedCoinDenom transfers by passing through to x/bank.

func (Keeper) SendCoinsFromAccountToModule ¶

func (k Keeper) SendCoinsFromAccountToModule(
	goCtx context.Context,
	senderAddr sdk.AccAddress,
	recipientModule string,
	amt sdk.Coins,
) error

SendCoinsFromModuleToModule transfers coins from a ModuleAccount to another. It will panic if either module account does not exist. An error is returned if the recipient module is the x/precisebank module account or if sending the tokens fails.

func (Keeper) SendCoinsFromModuleToAccount ¶

func (k Keeper) SendCoinsFromModuleToAccount(
	goCtx context.Context,
	senderModule string,
	recipientAddr sdk.AccAddress,
	amt sdk.Coins,
) error

SendCoinsFromModuleToAccount transfers coins from a ModuleAccount to an AccAddress. It will panic if the module account does not exist. An error is returned if the recipient address is blocked, if the sender is the x/precisebank module account, or if sending the tokens fails.

func (Keeper) SendCoinsFromModuleToModule ¶

func (k Keeper) SendCoinsFromModuleToModule(
	goCtx context.Context,
	senderModule string,
	recipientModule string,
	amt sdk.Coins,
) error

SendCoinsFromModuleToModule transfers coins from a ModuleAccount to another. It will panic if either module account does not exist. An error is returned if the recipient module is the x/precisebank module account or if sending the tokens fails.

func (Keeper) SetDenomMetaData ¶ added in v0.3.0

func (k Keeper) SetDenomMetaData(ctx context.Context, denomMetaData banktypes.Metadata)

func (*Keeper) SetFractionalBalance ¶

func (k *Keeper) SetFractionalBalance(
	ctx sdk.Context,
	address sdk.AccAddress,
	amount sdkmath.Int,
)

SetFractionalBalance sets the fractional balance for an address.

func (*Keeper) SetRemainderAmount ¶

func (k *Keeper) SetRemainderAmount(
	ctx sdk.Context,
	amount sdkmath.Int,
)

SetRemainderAmount sets the internal remainder amount.

func (Keeper) SpendableCoin ¶

func (k Keeper) SpendableCoin(
	goCtx context.Context,
	addr sdk.AccAddress,
	denom string,
) sdk.Coin

SpendableCoins returns the total balances of spendable coins for an account by address. If the account has no spendable coins, an empty Coins slice is returned.
