What Is An RPC Endpoint? Types & Examples

TL;DR

• RPC endpoints serve as gateways for Web3 applications to connect with blockchain nodes.
• They come in two types: public (openly accessible) and private (restricted access).
• When selecting an RPC endpoint, consider factors like compatibility, reliability, security, and support.
• Examples of projects using RPC endpoints include MetaMask, Chainlink, and Uniswap for Ethereum interactions.
• 1RPC offers a privacy-preserving alternative, ensuring user data protection through innovative techniques while providing access to multiple supported networks.

In Web3, Remote Procedure Calls (RPCs) facilitate communication between decentralized applications (dApps), smart contracts, and blockchain nodes. This enables developers to build decentralized and interoperable systems. Central to this communication infrastructure are RPC endpoints (a component of an RPC), that serve as a gateway for Web3-enabled applications. In this article, we delve into the intricacies of RPC endpoints within the Web3 ecosystem, exploring their types, selection criteria, configuration methods, and real-world applications.

What are Remote Procedure Calls (RPCs)?

Before diving into RPC endpoints, it’s essential to grasp the significance of Remote Procedure Calls within the Web3 paradigm. RPCs in Web3 enable dApps to interact with smart contracts and blockchain networks (such as Ethereum, Polygon, Solana, and Injective. This allows for the execution of functions and retrieval of data across distributed systems. As such, RPCs are fundamental components that make decentralization possible.

What Is an RPC Endpoint (RPC URL)?

At the heart of Web3 communication lies the RPC endpoint, acting as the bridge between client-side applications and RPC Nodes. It is a URL that defines the network address and protocol used for communication with blockchain networks, allowing dApps to send transactions, query data, and interact with smart contracts. Essentially, an RPC endpoint serves as the gateway for Web3-enabled applications to access the decentralized web.

Difference Between Public vs. Private RPC’s

RPC endpoints within the Web3 ecosystem can be classified into different categories based on their accessibility and usage:

1. Public RPC Endpoints: These endpoints are openly accessible to developers and dApps, providing a convenient entry point to interact with blockchain networks. Public RPC endpoints are commonly used for prototyping, testing, and building decentralized applications.
2. Private RPC Endpoints: Unlike public endpoints, private Web3 RPC relays are restricted to authorized users or specific networks. These endpoints prioritize security and confidentiality, making them ideal for enterprise-grade applications and sensitive transactions within the Web3 ecosystem. One such example is 1RPC’s Plus Plans which offer a private connection to the blockchain.

How to Choose the Right RPC Endpoint for Your Web3 Application

Selecting the appropriate RPC endpoint is critical for the performance, security, and scalability of Web3 applications. Here’s a checklist to aid developers in making informed decisions:

1. Network Compatibility: Ensure compatibility with the blockchain network (e.g., Ethereum, Binance Smart Chain) your application interacts with, including support for relevant JSON-RPC protocols.
2. Reliability and Uptime: Choose endpoints with minimal downtime and high availability to ensure uninterrupted access to blockchain data and services.
3. Security Features: Prioritize endpoints with robust authentication mechanisms, encryption protocols, and rate-limiting capabilities to mitigate security risks and protect sensitive transactions.
4. Scalability: Consider the endpoint’s capacity to handle increasing transaction volumes and network congestion, especially during periods of high activity or gas fees.
5. Documentation and Support: Opt for endpoints with comprehensive documentation, developer resources, and responsive support channels to facilitate integration and troubleshooting.

How to Specify and Configure Your RPC Endpoint

Once you’ve chosen your endpoint type, it’s time to configure your dApp or wallet to interact with it.

With 1RPC you can follow the following steps to configure your RPC endpoint.

1. Choose your network: Specify which network you want to interact with (for example, Ethereum, Axelar, Aura, or Injective)
2. Check that your wallet has RPC settings and configurability
3. Navigate to add a new network
4. Paste the network details such as Chain ID, LCD URL, RPC URL, and Block Explorer into the relevant fields

The specific process may vary depending on the chosen blockchain platform and the development framework you’re using.

3 Examples of Projects Leveraging RPC Endpoints in the Web3 Ecosystem

Across the Web3 ecosystem, numerous projects harness RPC endpoints for decentralized applications, smart contracts, and blockchain infrastructure. Some notable examples include:

1. MetaMask: The popular Ethereum wallet and dApp browser utilize RPC endpoints to connect users to the Ethereum blockchain, enabling seamless interaction with decentralized applications and DeFi protocols.
2. Chainlink: The decentralized oracle network relies on RPC endpoints to fetch external data and trigger smart contract executions, facilitating real-world data integration and off-chain connectivity within decentralized applications.
3. Uniswap: The decentralized exchange protocol leverages RPC endpoints to interact with Ethereum smart contracts, enabling token swaps, liquidity provision, and automated market-making on the blockchain.

Get Started with These Top 3 Public RPC Endpoints in Web3

For developers embarking on Web3 development, here are some top public RPC endpoints worth exploring:

1. 1RPC: A privacy-preserving RPC that eradicates metadata exposure and leakage with a one-click user experience.
2. Infura: A widely used RPC endpoint provider offering reliable access to Ethereum, IPFS, and other blockchain networks, with scalable infrastructure and developer-friendly APIs.

1RPC — The Free Privacy-Preserving Web3 RPC Relay

While traditional public RPC endpoints offer a convenient entry point for Web3 development, they often come at the cost of user privacy. Your dApp’s interactions with the blockchain, including wallet addresses, IP locations, and even request timestamps, can be exposed. This raises concerns for privacy-conscious developers and users.

1RPC prioritizes user privacy within the Web3 ecosystem. It operates as a free public RPC relay that meticulously safeguards user data through a combination of innovative techniques:

On-chain Attestation

Unlike traditional opaque infrastructure, 1RPC leverages blockchain technology itself. Its hardware and software components are demonstrably verifiable on-chain, fostering complete transparency and trust.

Zero-Tracking Architecture

1RPC takes user privacy to the core by employing a “burn after relaying” approach. All metadata associated with user requests is meticulously erased after processing, ensuring true zero-tracking. This eliminates the possibility of 1RPC storing or even having access to your personal data.

Customizable Security

1RPC empowers developers to tailor their security posture. You can generate a unique API key with our Plus Plans which function across multiple supported networks, ensuring a private connection between your wallet and the blockchain.

Higher Rate Limits and Transaction Sanitizers

1RPC subscription plans provide users with a bespoke RPC endpoint, including tailored support for developer testnets, including Mode Testnet.

Other Plus features include higher rate limits and transaction sanitizers, which are anti-phishing controls that can be accessed via simple toggles.

Conclusion

RPC endpoints play a pivotal role in enabling seamless communication and interaction within the Web3 ecosystem, empowering developers to build decentralized applications, smart contracts, and blockchain infrastructure. By understanding the nuances of RPC endpoints and following best practices in their selection, configuration, and integration, developers can unlock the full potential of Web3 and drive innovation in the decentralized web.
