Functions

func ConstructMedianPokeMessage added in v0.19.2 

func ConstructMedianPokeMessage(wat string, val *bn.DecFloatPointNumber, age time.Time) []byte

ConstructMedianPokeMessage returns the message expected to be signed via ECDSA for calling Median.poke method.

The message structure is defined as: H(val ‖ age ‖ wat)

Where: - val: a price value - age: a time when the price was observed - wat: an asset name

func ConstructScribeOpPokeMessage added in v0.19.2 

func ConstructScribeOpPokeMessage(wat string, pokeData PokeData, schnorrData SchnorrData, signersBlob []byte) []byte

ConstructScribeOpPokeMessage returns the message expected to be signed via ECDSA for calling OpScribe.opPoke method.

The message structure is defined as: H(wat ‖ val ‖ age ‖ signature ‖ commitment ‖ signersBlob)

Where: - wat: an asset name - val: a price value - age: a time when the price was observed - signature: a Schnorr signature - commitment: a Schnorr commitment - signersBlob: a byte slice with signers indexes obtained from a contract

func ConstructScribePokeMessage added in v0.19.2 

func ConstructScribePokeMessage(wat string, pokeData PokeData) []byte

ConstructScribePokeMessage returns the message expected to be signed via ECDSA for calling Scribe.poke method.

The message is defined as: H(wat ‖ val ‖ age)

Where: - wat: an asset name - val: a price value - age: a time when the price was observed

func IsRevert added in v0.20.0 

func IsRevert(err error) bool

IsRevert returns true if execution of the call was reverted.

func SignersBlob 

func SignersBlob(signers []types.Address, feeds []types.Address, indices []uint8) ([]byte, error)

SignersBlob helps to generate signersBlob for PokeData struct.
