Porting from web3j

We made caver-java as similar as possible to web3j for portability. The below code snippets show how to port an application written in web3j to caver-java.

/* start a client */

Web3j web3 = Web3j.build(new HttpService(<endpoint>)); // Web3j

Caver caver = Caver.build(new HttpService(<endpoint>)); // caver-java

/* get nonce */

BigInteger nonce = web3j.ethGetTransactionCount(<address>, <blockParam>).send().getTransactionCount(); // Web3j

Quantity nonce = caver.klay().getTransactionCount(<address>, <blockParam>).send().getValue(); // caver-java

/* convert unit */

Convert.toWei("1.0", Convert.Unit.ETHER).toBigInteger(); // Web3j

Convert.toPeb("1.0", Convert.Unit.KLAY).toBigInteger(); // caver-java

/* generate wallet file */

WalletUtils.generateNewWalletFile(<password>, <filepath>); // Web3j

KlayWalletUtils.generateNewWalletFile(<address>, <password>, <filepath>); // caver-java

/* load credentials */

Credentials credentials = WalletUtils.loadCrendetials(<password>, <filepath>"); // Web3j

KlayCredentials credentials = KlayWalletUtils.loadCredentials(<password>, <filepath>); // caver-java

/* Value Transfer */

TransactionReceipt transactionReceipt = Transfer.sendFunds(...),send(); // Web3j

KlayTransactionReceipt.TransactionReceipt transactionReceipt = ValueTransfer.sendFunds().send(); // caver-java
