type AccountKeeper ¶

type AccountKeeper interface {
	GetParams(ctx sdk.Context) (params types.Params)
	GetAccount(ctx sdk.Context, addr sdk.AccAddress) types.AccountI
	SetAccount(ctx sdk.Context, acc types.AccountI)
	GetModuleAddress(moduleName string) sdk.AccAddress
	NewAccountWithAddress(ctx sdk.Context, addr sdk.AccAddress) types.AccountI
}

AccountKeeper defines the contract needed for AccountKeeper related APIs. Interface provides support to use non-sdk AccountKeeper for AnteHandler's decorators.

type DeductFeeDecorator ¶

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

DeductFeeDecorator deducts fees from the first signer of the tx If the first signer does not have the funds to pay for the fees, return with InsufficientFunds error Call next AnteHandler if fees successfully deducted CONTRACT: Tx must implement FeeTx interface to use DeductFeeDecorator

func NewDeductFeeDecorator(projectKeeper projectkeeper.Keeper, ak authante.AccountKeeper, bk bankkeeper.Keeper,
	iidKeeper iidkeeper.Keeper) DeductFeeDecorator

func (dfd DeductFeeDecorator) AnteHandle(ctx sdk.Context, tx sdk.Tx, simulate bool, next sdk.AnteHandler) (newCtx sdk.Context, err error)

type SetPubKeyDecorator ¶

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

func NewSetPubKeyDecorator(projectKeeper projectkeeper.Keeper, ak AccountKeeper) SetPubKeyDecorator

func (spkd SetPubKeyDecorator) AnteHandle(ctx sdk.Context, tx sdk.Tx, simulate bool, next sdk.AnteHandler) (sdk.Context, error)

type SetUpContextDecorator ¶

type SetUpContextDecorator struct{}

SetUpContextDecorator sets the GasMeter in the Context and wraps the next AnteHandler with a defer clause to recover from any downstream OutOfGas panics in the AnteHandler chain to return an error with information on gas provided and gas used. CONTRACT: Must be first decorator in the chain CONTRACT: Tx must implement GasTx interface

func NewSetUpContextDecorator() SetUpContextDecorator

func (sud SetUpContextDecorator) AnteHandle(ctx sdk.Context, tx sdk.Tx, simulate bool, next sdk.AnteHandler) (newCtx sdk.Context, err error)

type SigVerificationDecorator ¶

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

CONTRACT: Pubkeys are set in context for all signers before this decorator runs CONTRACT: Tx must implement SigVerifiableTx interface

func NewSigVerificationDecorator(ak AccountKeeper, projectKeeper projectkeeper.Keeper, signModeHandler authsigning.SignModeHandler) SigVerificationDecorator

func (svd SigVerificationDecorator) AnteHandle(ctx sdk.Context, tx sdk.Tx, simulate bool, next sdk.AnteHandler) (newCtx sdk.Context, err error)
