KeyPrefixBaseFeeV1 TODO: Temporary will be removed with params refactor PR

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 storetypes.StoreKey,
	ss paramstypes.Subspace,
) Keeper

NewKeeper generates new fee market module keeper

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) error

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) error

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) GetBaseFeeV1

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) types.Params

GetParams returns the total set of fee market parameters.

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, p types.Params) error

SetParams sets the fee market params in a single key

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.

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

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

Migrate3to4 migrates the store from consensus version 3 to 4
