                                          ContractCall implements bind.ContractCaller executing an Ethereum contract call with the specified data as the input. The pending flag requests execution against the pending block, not the stable head of the chain.

                                          func (*ContractBackend) PendingCodeAt

                                              PendingAccountNonce implements bind.ContractTransactor retrieving the current pending nonce associated with an account.

                                              func (*ContractBackend) SendTransaction

                                              func (b *ContractBackend) SendTransaction(ctx context.Context, tx *types.Transaction) error

                                                SendTransaction implements bind.ContractTransactor injects the transaction into the pending pool for execution.
