Types

type Keeper 

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

Keeper grants access to the Fee Market module state.

func NewKeeper 

func NewKeeper(
	cdc codec.BinaryCodec, authority sdk.AccAddress, storeKey, transientKey storetypes.StoreKey, ss paramstypes.Subspace,
) Keeper

NewKeeper generates new fee market module keeper

func (Keeper) AddTransientGasWanted 

func (k Keeper) AddTransientGasWanted(ctx sdk.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) BeginBlock 

func (k *Keeper) BeginBlock(ctx sdk.Context, _ abci.RequestBeginBlock)

BeginBlock updates base fee

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 sdk.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) EndBlock 

func (k *Keeper) EndBlock(ctx sdk.Context, _ abci.RequestEndBlock)

EndBlock update block gas wanted. The EVM end block logic doesn't update the validator set, thus it returns an empty slice.

func (Keeper) GetBaseFee 

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

GetBaseFee gets the base fee from the store

func (Keeper) GetBaseFeeEnabled added in v0.20.0 

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

GetBaseFeeEnabled returns true if base fee is enabled

func (Keeper) GetBaseFeeV1 added in v0.20.0 

func (k Keeper) GetBaseFeeV1(ctx sdk.Context) *big.Int

GetBaseFeeV1 get the base fee from v1 version of states. return nil if base fee is not enabled TODO: Figure out if this will be deleted ?

func (Keeper) GetBlockGasWanted 

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

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

func (Keeper) GetParams 

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

GetParams returns the total set of fee market parameters.

func (Keeper) GetTransientGasWanted 

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

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

func (Keeper) Logger 

func (k Keeper) Logger(ctx sdk.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 sdk.Context, baseFee *big.Int)

SetBaseFee set's the base fee in the store

func (Keeper) SetBlockGasWanted 

func (k Keeper) SetBlockGasWanted(ctx sdk.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 sdk.Context, params types.Params) error

SetParams sets the fee market params in a single key

func (Keeper) SetTransientBlockGasWanted 

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

SetTransientBlockGasWanted sets the block gas wanted to the transient store.

func (*Keeper) UpdateParams added in v0.21.0 

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.

type Migrator 

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

Migrator is a struct for handling in-place store migrations.

func NewMigrator 

func NewMigrator(keeper Keeper, legacySubspace types.Subspace) Migrator

NewMigrator returns a new Migrator.

func (Migrator) Migrate3to4 added in v0.21.0 

func (m Migrator) Migrate3to4(ctx sdk.Context) error

Migrate3to4 migrates the store from consensus version 3 to 4
