By default, when a new transaction is submitted by web3j to an Ethereum client, web3j will continually poll the client until it receives a TransactionReceipt. A smart contract is a self-executing program that automates the actions required in a blockchain transaction. Once completed, the transactions are trackable. In Solidity, the contract type is a struct that organizes a set of related functions around a single purpose. Address types are Ethereum addresses that equate. So far, we have mostly interacted and modified state variables from our Smart Contract. For example, when we write the address, we modify a state variable. When. A smart contract is simply an application that lives on the blockchain. It includes access to the blockchain's state and all the other smart contracts that are.
