Getting started for devs

Here's how you can begin using obscura for devs

For Developers: Integrating with Obscura SDK

The Obscura SDK is designed to provide developers with powerful tools for integrating transaction privacy and security into Solana-based blockchain applications. This guide outlines how to set up and leverage the SDK's capabilities.

---

Step 1: Install the Obscura SDK

Installation:

1. Set Up Your Development Environment: Ensure you have a compatible environment, such as Node.js for JavaScript or TypeScript development.

2. Install the SDK: Use your preferred package manager to install the SDK:

   npm install obscura-sdk

   or

   yarn add obscura-sdk

---

Step 2: Initialize the SDK

Initialize the SDK to start using Obscura's secure transaction features for Solana.

const Obscura = require('obscura-sdk');

const obscura = new Obscura({
    rpcUrl: '<Your Obscura RPC URL>',
    apiKey: '<Your API Key>'
});

• rpcUrl: The Solana RPC URL provided by Obscura.

• apiKey: Your unique API key for authentication.

---

Step 3: Encrypt Transactions

Use the SDK to encrypt transaction data before submission.

async function sendTransaction(transactionData) {
    try {
        const encryptedData = await obscura.encryptTransaction(transactionData);
        const response = await obscura.sendTransaction(encryptedData);
        console.log('Transaction sent successfully:', response);
    } catch (error) {
        console.error('Error sending transaction:', error);
    }
}

// Example usage
const transactionData = {
    from: 'SenderPublicKey',
    to: 'RecipientPublicKey',
    amount: 1000000000 // Amount in lamports (1 SOL = 1,000,000,000 lamports)
};

sendTransaction(transactionData);

---

Step 4: Validate Transactions with zk-SNARKs

Ensure transactions comply with Solana rules using Obscura's validation methods.

async function validateAndSend(transactionData) {
    try {
        const encryptedData = await obscura.encryptTransaction(transactionData);
        const isValid = await obscura.validateTransaction(encryptedData);

        if (isValid) {
            console.log('Transaction is valid and secure.');
            const response = await obscura.sendTransaction(encryptedData);
            console.log('Transaction sent:', response);
        } else {
            console.error('Invalid transaction.');
        }
    } catch (error) {
        console.error('Error validating transaction:', error);
    }
}

---

Step 5: Monitor and Debug

Leverage monitoring tools to track transaction status and debug encrypted payloads.

async function monitorTransaction(signature) {
    try {
        const status = await obscura.getTransactionStatus(signature);
        console.log(`Transaction status for ${signature}:`, status);
    } catch (error) {
        console.error('Error fetching transaction status:', error);
    }
}

// Example usage
monitorTransaction('5Nz3vBhEt3YTpHAG3dd7rJL3fKmT2dphRf8DhHEyDHT1');

• Debugging Encrypted Payloads:

  async function debugPayload(encryptedData) {
      try {
          const decryptedData = await obscura.decryptTransaction(encryptedData);
          console.log('Decrypted Transaction Data:', decryptedData);
      } catch (error) {
          console.error('Error decrypting transaction data:', error);
      }
  }

---

Advanced Features

Batch Processing

Encrypt and send multiple transactions efficiently.

async function sendBatchTransactions(transactions) {
    try {
        const encryptedBatch = await Promise.all(transactions.map(tx => obscura.encryptTransaction(tx)));
        const responses = await Promise.all(encryptedBatch.map(encryptedTx => obscura.sendTransaction(encryptedTx)));
        console.log('Batch transactions sent successfully:', responses);
    } catch (error) {
        console.error('Error processing batch transactions:', error);
    }
}

const batchTransactions = [
    { from: 'PublicKey1', to: 'PublicKey2', amount: 500000000 },
    { from: 'PublicKey3', to: 'PublicKey4', amount: 1000000000 }
];

sendBatchTransactions(batchTransactions);

Transaction Cost Estimation

Estimate fees for Solana transactions before sending.

async function estimateTransactionCost(transactionData) {
    try {
        const cost = await obscura.estimateTransactionFee(transactionData);
        console.log('Estimated transaction cost:', cost);
    } catch (error) {
        console.error('Error estimating transaction cost:', error);
    }
}

estimateTransactionCost(transactionData);

---

Step 6: Simulate Transactions

Simulate transactions on the Solana network to validate their behavior before submission.

async function simulateTransaction(transactionData) {
    try {
        const simulationResult = await obscura.simulateTransaction(transactionData);
        console.log('Simulation result:', simulationResult);
    } catch (error) {
        console.error('Error simulating transaction:', error);
    }
}

// Example usage
simulateTransaction({
    from: 'SenderPublicKey',
    to: 'RecipientPublicKey',
    amount: 1000000000
});

By following these steps, developers can seamlessly integrate Obscura's advanced security features into their Solana blockchain applications, ensuring robust privacy and protection against threats.
