XRP (Ripple) Comprehensive Operation Guide

Introduction to XRP Operations

This guide demonstrates four essential XRP functionalities using a test environment:

1. Offline transaction signing
2. XRP deposits
3. Key pair generation (requires self-hosted XRP node)
4. Balance inquiries

Technical Setup

Maven Configuration

First, download and install these two essential JAR packages:

• ripple-bouncycastle
• ripple-core

Download options:
👉 Get ripple-lib-java from GitHub

Add to your pom.xml:

<dependency>
    <groupId>com.ripple</groupId>
    <artifactId>ripple-bouncycastle</groupId>
    <version>1.0.0</version>
</dependency>

<dependency>
    <groupId>com.ripple</groupId>
    <artifactId>ripple-core</groupId>
    <version>1.0.0</version>
</dependency>

Core Functionalities

1. Transaction Signing

public String sign(String fromAddress, String privateKey, String toAddress, 
                  Long value, Long fee, String memo) {
    Map map = getAccountInfo(fromAddress);
    Payment payment = new Payment();
    payment.as(AccountID.Account, fromAddress);
    payment.as(AccountID.Destination, toAddress);
    payment.as(UInt32.DestinationTag, memo);
    payment.as(Amount.Amount, value.toString());
    payment.as(UInt32.Sequence, map.get("accountSequence"));
    payment.as(UInt32.LastLedgerSequence, map.get("ledgerCurrentIndex") + 4);
    payment.as(Amount.Fee, fee.toString());
    SignedTransaction signed = payment.sign(privateKey);
    return signed != null ? signed.tx_blob : null;
}

2. Transaction Broadcasting

public String pushTx(String sign) throws Exception {
    if (StringUtils.isEmpty(sign)) {
        logger.error("Empty transaction signature");
        return null;
    }
    
    HashMap params = new HashMap();
    params.put("tx_blob", sign);
    JSONObject json = doRequest(METHOD_POST_SUBMIT, params);
    
    if (!isError(json)) {
        JSONObject result = json.getJSONObject(RESULT);
        if (result != null && TES_SUCCESS.equals(result.getString("engine_result"))) {
            return result.getJSONObject("tx_json").getString("hash");
        }
    }
    return null;
}

3. Account Balance Check

public Map getAccountInfo(String account) {
    HashMap params = new HashMap();
    params.put("account", account);
    params.put("strict", "true");
    params.put("ledger_index", "current");
    params.put("queue", "true");
    
    JSONObject response = doRequest(METHOD_POST_ACCOUNT_INFO, params);
    if (response != null && "success".equals(response.getJSONObject("result").getString("status"))) {
        Map<String, String> accountData = new HashMap();
        JSONObject resultData = response.getJSONObject("result").getJSONObject("account_data");
        accountData.put("accountSequence", resultData.getString("Sequence"));
        accountData.put("balance", resultData.getString("Balance"));
        accountData.put("ledgerCurrentIndex", response.getJSONObject("result").getString("ledger_current_index"));
        return accountData;
    }
    return null;
}

Value Conversion Utilities

public BigDecimal unitToMax(Long number) {
    return new BigDecimal(number).divide(BigDecimal.valueOf(1000000), 6, BigDecimal.ROUND_HALF_UP);
}

public Long unitToMini(BigDecimal number) {
    return number.multiply(BigDecimal.valueOf(1000000))
                .setScale(6, BigDecimal.ROUND_HALF_UP)
                .longValue();
}

Key Pair Generation

public void createKey() {
    JSONObject jsonObject = doRequest("wallet_propose", new HashMap<>());
    System.out.println(jsonObject);
}

Frequently Asked Questions

How secure is offline XRP signing?

Offline signing provides maximum security by keeping private keys completely disconnected from the internet during transaction preparation.

What's the minimum XRP transaction fee?

The current minimum is 0.00001 XRP, though fees may vary based on network conditions.

Can I generate XRP key pairs without running a node?

👉 Learn about XRP key generation alternatives

How often should I check XRP ledger sequence numbers?

Always check the latest ledger index before transactions, as it changes approximately every 3-5 seconds.

What's the purpose of destination tags?

They identify specific recipients when multiple users share a single XRP address, commonly used by exchanges.

Best Practices

1. Always verify transaction details before signing
2. Regularly update your ripple-lib-java dependencies
3. Implement proper error handling for network requests
4. Store private keys securely using hardware wallets when possible
5. Test all transactions on the testnet before mainnet deployment

For advanced implementations, consider consulting the official Ripple documentation and developer forums.
