Overview ¶

Package feegrant provides functionality for authorizing the payment of transaction fees from one account (key) to another account (key).

Effectively, this allows for a user to pay fees using the balance of an account different from their own. Example use cases would be allowing a key on a device to pay for fees using a master wallet, or a third party service allowing users to pay for transactions without ever really holding their own tokens. This package provides ways for specifying fee allowances such that authorizing fee payment to another account can be done with clear and safe restrictions.

A user would authorize granting fee payment to another user using MsgGrantAllowance and revoke that delegation using MsgRevokeAllowance. In both cases, Granter is the one who is authorizing fee payment and Grantee is the one who is receiving the fee payment authorization. So grantee would correspond to the one who is signing a transaction and the granter would be the address that pays the fees.

The fee allowance that a grantee receives is specified by an implementation of the FeeAllowance interface. Two FeeAllowance implementations are provided in this package: BasicAllowance and PeriodicAllowance.

Package feegrant is a reverse proxy.

It translates gRPC into RESTful JSON APIs.

Functions ¶

func FeeAllowanceKey ¶ 

func FeeAllowanceKey(granter sdk.AccAddress, grantee sdk.AccAddress) []byte

FeeAllowanceKey is the canonical key to store a grant from granter to grantee We store by grantee first to allow searching by everyone who granted to you

func FeeAllowancePrefixByGrantee ¶ 

func FeeAllowancePrefixByGrantee(grantee sdk.AccAddress) []byte

FeeAllowancePrefixByGrantee returns a prefix to scan for all grants to this given address.

func RegisterInterfaces ¶ 

func RegisterInterfaces(registry types.InterfaceRegistry)

RegisterInterfaces registers the interfaces types with the interface registry

func RegisterMsgServer ¶ 

func RegisterMsgServer(s grpc1.Server, srv MsgServer)

func RegisterQueryHandler ¶ 

func RegisterQueryHandler(ctx context.Context, mux *runtime.ServeMux, conn *grpc.ClientConn) error

RegisterQueryHandler registers the http handlers for service Query to "mux". The handlers forward requests to the grpc endpoint over "conn".

func RegisterQueryHandlerClient ¶ 

func RegisterQueryHandlerClient(ctx context.Context, mux *runtime.ServeMux, client QueryClient) error

RegisterQueryHandlerClient registers the http handlers for service Query to "mux". The handlers forward requests to the grpc endpoint over the given implementation of "QueryClient". Note: the gRPC framework executes interceptors within the gRPC handler. If the passed in "QueryClient" doesn't go through the normal gRPC flow (creating a gRPC client etc.) then it will be up to the passed in "QueryClient" to call the correct interceptors.

func RegisterQueryHandlerFromEndpoint ¶ 

func RegisterQueryHandlerFromEndpoint(ctx context.Context, mux *runtime.ServeMux, endpoint string, opts []grpc.DialOption) (err error)

RegisterQueryHandlerFromEndpoint is same as RegisterQueryHandler but automatically dials to "endpoint" and closes the connection when "ctx" gets done.

func RegisterQueryHandlerServer ¶ 

func RegisterQueryHandlerServer(ctx context.Context, mux *runtime.ServeMux, server QueryServer) error

RegisterQueryHandlerServer registers the http handlers for service Query to "mux". UnaryRPC :call QueryServer directly. StreamingRPC :currently unsupported pending https://github.com/grpc/grpc-go/issues/906. Note that using this registration option will cause many gRPC library features (such as grpc.SendHeader, etc) to stop working. Consider using RegisterQueryHandlerFromEndpoint instead.

func RegisterQueryServer ¶

type PeriodicAllowance ¶ 

type PeriodicAllowance struct {
	// basic specifies a struct of `BasicAllowance`
	Basic BasicAllowance `protobuf:"bytes,1,opt,name=basic,proto3" json:"basic"`
	// period specifies the time duration in which period_spend_limit coins can
	// be spent before that allowance is reset
	Period time.Duration `protobuf:"bytes,2,opt,name=period,proto3,stdduration" json:"period"`

	PeriodCanSpend github_com_cosmos_cosmos_sdk_types.Coins `` /* 149-byte string literal not displayed */
	// period_reset is the time at which this period resets and a new one begins,
	// it is calculated from the start time of the first transaction after the
	// last period ended
	PeriodReset time.Time `protobuf:"bytes,5,opt,name=period_reset,json=periodReset,proto3,stdtime" json:"period_reset"`
}

PeriodicAllowance extends Allowance to allow for both a maximum cap, as well as a limit per time period.

func (*PeriodicAllowance) Accept ¶ 

func (a *PeriodicAllowance) Accept(ctx sdk.Context, fee sdk.Coins, _ []sdk.Msg) (bool, error)

Accept can use fee payment requested as well as timestamp of the current block to determine whether or not to process this. This is checked in Keeper.UseGrantedFees and the return values should match how it is handled there.

If it returns an error, the fee payment is rejected, otherwise it is accepted. The FeeAllowance implementation is expected to update it's internal state and will be saved again after an acceptance.

If remove is true (regardless of the error), the FeeAllowance will be deleted from storage (eg. when it is used up). (See call to RevokeAllowance in Keeper.UseGrantedFees)
