Types

type DenomOracleExchangeRatePair

type DenomOracleExchangeRatePair struct {
	Denom                 string             `json:"denom"`
	OracleExchangeRateVal OracleExchangeRate `json:"oracleExchangeRateVal"`
}

type OracleExchangeRate

type OracleExchangeRate struct {
	ExchangeRate        string `json:"exchangeRate"`
	LastUpdate          string `json:"lastUpdate"`
	LastUpdateTimestamp int64  `json:"lastUpdateTimestamp"`
}

Define types which deviate slightly from cosmos types (ExchangeRate string vs sdk.Dec)

type OracleTwap

type OracleTwap struct {
	Denom           string `json:"denom"`
	Twap            string `json:"twap"`
	LookbackSeconds int64  `json:"lookbackSeconds"`
}

type Precompile

type Precompile struct {
	pcommon.Precompile

	GetExchangeRatesId []byte
	GetOracleTwapsId   []byte
	// contains filtered or unexported fields
}

func NewPrecompile

func NewPrecompile(oracleKeeper pcommon.OracleKeeper, evmKeeper pcommon.EVMKeeper) (*Precompile, error)

func (Precompile) Address

func (p Precompile) Address() common.Address

func (Precompile) GetName

func (p Precompile) GetName() string

func (Precompile) IsTransaction

func (Precompile) IsTransaction(string) bool

func (Precompile) RequiredGas

func (p Precompile) RequiredGas(input []byte) uint64

RequiredGas returns the required bare minimum gas to execute the precompile.

func (Precompile) Run

func (p Precompile) Run(evm *vm.EVM, _ common.Address, _ common.Address, input []byte, value *big.Int, _ bool) (bz []byte, err error)
