Functions

func CreateOracleClaimFromEthClaim 

func CreateOracleClaimFromEthClaim(cdc *codec.Codec, ethClaim EthBridgeClaim) (oracle.Claim, error)

CreateOracleClaimFromEthClaim converts a specific ethereum bridge claim to a general oracle claim to be used by the oracle module. The oracle module expects every claim for a particular prophecy to have the same id, so this id must be created in a deterministic way that all validators can follow. For this, we use the Nonce an Ethereum Sender provided, as all validators will see this same data from the smart contract.

func ErrInvalidEthAddress 

func ErrInvalidEthAddress(codespace sdk.CodespaceType) sdk.Error

ErrInvalidEthAddress implements sdk.Error.

func ErrInvalidEthNonce 

func ErrInvalidEthNonce(codespace sdk.CodespaceType) sdk.Error

func ErrInvalidEthSymbol 

func ErrInvalidEthSymbol(codespace sdk.CodespaceType) sdk.Error

func ErrJSONMarshalling 

func ErrJSONMarshalling(codespace sdk.CodespaceType) sdk.Error

func RegisterCodec 

func RegisterCodec(cdc *codec.Codec)
