Custom RPC Providers

Introduction

Backpac allows you to bring your Custom RPC Providers into the platform, enabling you to configure any RPC node provider you choose alongside our integrated options like Alchemy. This flexibility gives you complete control over your blockchain network’s performance, allowing you to diversify the RPC providers in use. Whether you're looking to reduce costs, improve performance, or meet specific use case requirements, Backpac's support for Custom RPC Providers ensures that your system operates according to your exact needs.

What Are Custom RPC Providers?

Custom RPC Providers are RPC endpoints that you configure within Backpac, allowing you to connect your own preferred blockchain node providers instead of or alongside the platform's predefined ones. You can add custom providers from various networks to suit your workload requirements.

Benefits of Using Custom RPC Providers:

• Flexibility: Use any RPC provider that fits your specific requirements.
• Cost Optimization: Choose providers that offer better pricing or lower overhead costs for specific blockchain operations.
• Customizability: Tailor your blockchain network architecture to include specific providers, whether for performance, reliability, or geographic reasons.
• Load Balancing: Distribute workloads across your selected RPC providers through Backpac's Load Balancer to ensure high availability and optimal resource utilization.

How Backpac Handles Custom RPC Providers

Step 1: Adding a Custom RPC Provider

1. Log in to Backpac: Navigate to your Backpac dashboard.

2. Go to Load Balancer Settings: click on RPC Providers.

3. Enter Provider Details: Enter the necessary details for your RPC provider, such as:

   • Provider Name: Choose a name that represents your custom provider.
   • Blockchain: Specify the blockchain network (e.g., Ethereum, Solana, Binance Smart Chain).
   • Network: Specify the blockchain network (e.g., Mainnet, Goerli, DEVNET).
   • RPC URL: Provide the endpoint URL of the RPC provider you wish to use.
   • RPC WS URL: Provide the endpoint URL of the RPC provider you wish to use.
   • Authentication (Optional): Include any authentication tokens or credentials needed for the provider.

4. Save the Provider: Once the details are entered, click Save to add the custom provider to your Backpac configuration.

Step 2: Configuring Custom RPC Providers in Target Groups

1. Create or Edit Target Group: Navigate to Target Groups under your Load Balancer settings.

2. Add Custom RPC Provider to Target Group: When setting up or editing a Target Group, you can add your Custom RPC Providers to the group.

   • Select RPC Provider: Choose from the list of available providers, including your custom provider.
   • Define Group Settings: Set up parameters for load balancing, such as weight distribution between providers.

3. Save and Apply: After adding your custom providers to the Target Group, save your settings to apply the changes.

Step 3: Configuring Load Balancer Listener Rules

1. Create or Edit Listener Rule: Go to the Listener Rules section to create a new listener or modify an existing one.
2. Assign Target Group: Link the Target Group that includes your Custom RPC Providers to the listener rule.
   • Set Criteria: Define rules such as HTTP headers, RPC methods, or IP address ranges to match requests with the appropriate Target Group.
3. Apply Listener Rule: Save the listener rule, which will ensure that traffic is routed to the correct Target Group based on the defined conditions.

Use Case Example: Custom RPC Provider Setup for Ethereum and Solana

Let's say you have custom RPC providers for both Ethereum and Solana networks, and you'd like to use them in your Backpac setup for better performance and cost savings.

1. Add Custom Ethereum Provider:

   • You may have a custom Ethereum RPC provider offering lower fees or faster response times.
   • Add the provider’s endpoint URL and set it up as a Custom RPC Provider in Backpac.

2. Add Custom Solana Provider:

   • Similarly, you can add a Solana RPC provider that might be geographically closer to your users for faster response times.

3. Create Target Groups for Ethereum and Solana:

   • Set up two Target Groups: one for Ethereum and another for Solana, including the custom RPC endpoints for both networks.

4. Configure Listener Rules:

   • Create listener rules to route traffic to the respective Target Groups based on the blockchain method being requested (e.g., route Ethereum-related methods to the Ethereum Target Group).

5. Load Balancer Traffic Routing:

   • Traffic will be intelligently routed to the appropriate Custom RPC Providers based on the listener rules, ensuring high availability and optimal performance for both Ethereum and Solana.

Conclusion

By integrating Custom RPC Providers into Backpac’s Load Balancer, you can take full control over your blockchain network’s performance, cost, and reliability. Whether you’re using a custom Ethereum provider for specific transactions or adding multiple Solana endpoints, Backpac’s flexible system allows you to scale and optimize your blockchain architecture efficiently. With intelligent traffic routing, monitoring, and custom configurations, you have everything you need to meet your system's needs.
