All one has to do is pass the ganache provider as an argument to the web3 instance(web3 facilitates the connection between the blockchain network and the js application).īefore deploying a smart contract to an actual Ethereum network make sure the account has some ether in it. It takes care of everything and the user doesn’t have to worry about the security and the gas amount required for transactions since everything is happening on a local test network. Deploying To A Local NetworkĪn emulator can be used to deploy a smart contract on a local network eg. Deployment of a smart contract is done by sending a transaction to the network with bytecode. One can create multiple instances of a smart contract on the network or multiple networks. ![]() When a smart contract is deployed, it creates an instance (contract account) on the network. ![]() Unlike a smart contract, an external account can connect to multiple Ethereum networks (Rinkebey, Kovan, main, etc.) whereas a smart contract is only specific to one individual network (the network it is deployed on). It is like an Ethereum account but there is a critical difference between an external account and a smart contract. Smart contracts are blocks of code that reside on the blockchain.
