Smart Contract Deploy

TxTypeSmartContractDeploy deploys a smart contract to the given address. 이 트랜잭션 유형에 따라 다음과 같은 변경 사항이 적용됩니다.

Import the ethers and @kaiachain/ethers-ext modules to add kaia features on ethers.js.

Define sender address and sender private key

Set up the provider with the specified kairos testnet URL. A provider in ethers is a read-only abstraction to access the blockchain data.

Also, you can change the provider URL from kairos to quicknode

Create a sender's wallet using the sender's private key and the provider

Declare a transaction object

Specify the transaction type as SmartContractDeploy

Set the compiled bytecode from the solidity code you want to deploy to the blockchain network

Send the tx to the blockchain. Function sendTransaction internally signs with the private key of the account and then transmits it to the blockchain network.

The wait function returns the tx receipt if it is completed in the blockchain.
