Types

type Keeper

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

Keeper grants access to the Fee Market module states.

func NewKeeper

func NewKeeper(
	cdc codec.BinaryCodec, authority cosmos.AccAddress, storeKey, transientKey storetypes.StoreKey, ss paramsmodule.Subspace,
) *Keeper

NewKeeper generates new fee market module keeper

func (Keeper) AddTransientGasWanted

func (k Keeper) AddTransientGasWanted(ctx cosmos.Context, gasWanted uint64) (uint64, error)

AddTransientGasWanted adds the cumulative gas wanted in the transient store

func (Keeper) BaseFee

func (k Keeper) BaseFee(c context.Context, _ *types.QueryBaseFeeRequest) (*types.QueryBaseFeeResponse, error)

BaseFee implements the Query/BaseFee gRPC method

func (Keeper) BlockGas

func (k Keeper) BlockGas(c context.Context, _ *types.QueryBlockGasRequest) (*types.QueryBlockGasResponse, error)

BlockGas implements the Query/BlockGas gRPC method

func (Keeper) CalculateBaseFee

func (k Keeper) CalculateBaseFee(ctx cosmos.Context) *big.Int

CalculateBaseFee calculates the base fee for the current block. This is only calculated once per block during BeginBlock. If the NoBaseFee parameter is enabled or below activation height, this function returns nil. NOTE: This code is inspired from the go-ethereum EIP1559 implementation and adapted to Cosmos SDK-based chains. For the canonical code refer to: https://github.com/ethereum/go-ethereum/blob/master/consensus/misc/eip1559.go

func (Keeper) GetBaseFee

func (k Keeper) GetBaseFee(ctx cosmos.Context) *big.Int

GetBaseFee gets the base fee from the store

func (Keeper) GetBaseFeeEnabled

func (k Keeper) GetBaseFeeEnabled(ctx cosmos.Context) bool

GetBaseFeeEnabled returns true if base fee is enabled

func (Keeper) GetBlockGasWanted

func (k Keeper) GetBlockGasWanted(ctx cosmos.Context) uint64

GetBlockGasWanted returns the last block gas wanted value from the store.

func (Keeper) GetParams

func (k Keeper) GetParams(ctx cosmos.Context) (params types.Params)

GetParams returns the total set of fee market parameters.

func (Keeper) GetTransientGasWanted

func (k Keeper) GetTransientGasWanted(ctx cosmos.Context) uint64

GetTransientGasWanted returns the gas wanted in the current block from transient store.

func (Keeper) Logger

func (k Keeper) Logger(ctx cosmos.Context) log.Logger

Logger returns a module-specific logger.

func (Keeper) Params

func (k Keeper) Params(c context.Context, _ *types.QueryParamsRequest) (*types.QueryParamsResponse, error)

Params implements the Query/Params gRPC method

func (Keeper) SetBaseFee

func (k Keeper) SetBaseFee(ctx cosmos.Context, baseFee *big.Int)

SetBaseFee set's the base fee in the store

func (Keeper) SetBlockGasWanted

func (k Keeper) SetBlockGasWanted(ctx cosmos.Context, gas uint64)

SetBlockGasWanted sets the block gas wanted to the store. CONTRACT: this should be only called during EndBlock.

func (Keeper) SetParams

func (k Keeper) SetParams(ctx cosmos.Context, params types.Params) error

SetParams sets the fee market params in a single key

func (Keeper) SetTransientBlockGasWanted

func (k Keeper) SetTransientBlockGasWanted(ctx cosmos.Context, gasWanted uint64)

SetTransientBlockGasWanted sets the block gas wanted to the transient store.

func (*Keeper) UpdateParams

func (k *Keeper) UpdateParams(goCtx context.Context, req *types.MsgUpdateParams) (*types.MsgUpdateParamsResponse, error)

UpdateParams implements the gRPC MsgServer interface. When an UpdateParams proposal passes, it updates the module parameters. The update can only be performed if the requested authority is the Cosmos SDK governance module account.
