func CtxAtHeight

func CtxAtHeight(height int64) context.Context

func EvmContractMethodId

func EvmContractMethodId(signature string) []byte

EvmContractMethodId encodes a method signature to the method id used in eth calldata.

func EvmToSdkAddress

func EvmToSdkAddress(addr common.Address) sdk.AccAddress

func GetAccAddress

func GetAccAddress(privKey cryptotypes.PrivKey) sdk.AccAddress

func NewGrpcConnection

func NewGrpcConnection(endpoint string) (*grpc.ClientConn, error)

NewGrpcConnection parses a GRPC endpoint and creates a connection to it

func PrettyPrintCoins

func PrettyPrintCoins(coins sdk.Coins) string

func SdkToEvmAddress

func SdkToEvmAddress(addr sdk.AccAddress) common.Address

func Sign

func Sign(
	txConfig sdkclient.TxConfig,
	privKey cryptotypes.PrivKey,
	txBuilder sdkclient.TxBuilder,
	signerData authsigning.SignerData,
) (authsigning.Tx, []byte, error)

Sign signs a populated TxBuilder and returns a signed Tx and raw transaction bytes

func WaitForEvmTxReceipt

func WaitForEvmTxReceipt(client *ethclient.Client, txHash common.Hash, timeout time.Duration) (*ethtypes.Receipt, error)

WaitForEvmTxReceipt polls for a tx receipt and errors on timeout. If the receipt comes back, but with status 0 (failed), an error is returned.

func WaitForSdkTxCommit

func WaitForSdkTxCommit(txClient txtypes.ServiceClient, txHash string, timeout time.Duration) (*sdk.TxResponse, error)

WaitForSdkTxCommit polls the chain until the tx hash is found or times out. Returns an error immediately if tx hash is empty
