	*ethclient.Client
	// contains filtered or unexported fields
}

func (*Client) ChainID

func (ec *Client) ChainID() *big.Int

func (*Client) GetClient

func (ec *Client) GetClient() *ethclient.Client

GetClients returns the instance of a ethclient already established connection to a JSON RPC Ethereum Node

func (*Client) ValidateContractDeployedAt

func (ec *Client) ValidateContractDeployedAt(contractAddress string) (*common.Address, error)

ValidateContractDeployedAt performs validation that a smart contract is deployed at the provided address

func (*Client) WaitForConfirmations

func (*Client) WaitForTransaction

func (ec *Client) WaitForTransaction(hex string, onSuccess, onRevert func(), onError func(err error))

WaitForTransaction waits for transaction receipt and depending on receipt status calls one of the provided functions onSuccess is called once the TX is successfully mined onRevert is called once the TX is mined but it reverted onError is called if an error occurs while waiting for TX to go into one of the other 2 states
