Choosing the Right RPC Provider for Your Web3 Project

OnFinality, a multi-chain infrastructure provider, highlights some of the key factors to consider when choosing your RPC provider such as security, reliability and scalability.

Choosing the Right RPC Provider for Your Web3 Project

OnFinality is a blockchain infrastructure platform that saves web3 builders time and makes their lives easier. We deliver easy-to-use, reliable and scalable API endpoints for the biggest blockchain networks and empower developers to automatically test, deploy, scale and monitor their own blockchain nodes in minutes.

If you’re on the hunt for a Remote Procedure Call (RPC) provider for your web3 application, you’re in the right place.

In this article, we explore the key criteria of a good RPC provider to help you make an informed decision when choosing your infrastructure partner.

We also provide concrete examples on how we’re continuously enhancing our RPC services with bleeding-edge features and adopting the latest industry standards to deliver the best possible service to web3 teams.

What is RPC and why is it important?

Remote Procedure Calls (RPCs) are services that help different parts of a web3 application talk to each other. They act like a bridge between the client and a remote server. In the context of web3, that could be your app or website and a blockchain network like Ethereum.

Why should I use an RPC provider?

By using an RPC provider, you can easily send requests and receive responses between your app and the remote server, without having to worry about the technical details of how the communication works.

The importance of choosing the right RPC provider

Understanding the key factors that contribute to a reliable RPC provider can help ensure the success of your web3 project.

Moreover, selecting the right one at the start not only sets the stage for a smooth and successful development journey, but also helps prevent disruptions when it comes time to scale your Decentralised Application (DApp).

What are some key criteria to consider?

Reliability and uptime

A provider with high reliability and uptime ensures that your application is available and functional for users at all times, helping you provide the best user experience possible.

A commonly used benchmark for measuring uptime would be via the percentage of time that a system is operational, measured using the number of nines (9s) from 99% — 99.9999%.

Achieving 99.9% uptime is a reasonable goal for DApps, but it is important to consider factors such as network congestion, node failure, and software bugs that can affect the performance of your apps. Some DApps may require higher levels of availability, such as those that handle financial transactions or store sensitive data.

Since inception in 2019, OnFinality has served hundreds of billions of requests to over 80 chains at a high target uptime of 99.99% (which means a downtime of 52.56 minutes per year!).

Security and privacy measures

The importance of security and privacy measures cannot be overstated, as these directly impact the safety and protection of sensitive data and users’ trust in your application.

Some best practices by RPC providers to prevent data breaches and other security risks include strong authentication mechanisms and access controls to prevent unauthorised access to sensitive data and systems, as well as compliance with relevant data protection and privacy regulations.

While OnFinality provides public endpoints across all of its supported chains, we highly recommend you to create a private API key, which will give you greater control over the security of your apps. Private API keys come with unique identifiers associated with a specific user or application, that can be used to authenticate or restrict API requests from specific users or applications.

API Access Restrictions

In addition to API Access Restrictions, OnFinality complies with various privacy protection laws around the world, notably the General Data Protection Regulation of the European Union (GDPR) and the equivalent laws of the United Kingdom (UK GDPR) when dealing with personal information.

Chain compatibility and ease-of-integration

A provider that supports multiple blockchain networks and provides easy-to-use APIs can greatly improve the user experience by facilitating the seamless integration and utility of DApps across different chains and ecosystems.

For example, compatibility with EVM (Ethereum Virtual Machine) chains allows developers to leverage the vast ecosystem of existing Ethereum tools and smart contracts, while IBC (Inter-Blockchain Communication) compatibility enables the creation of multi-chain apps that can be interoperable between different blockchains.

OnFinality currently supports over 80 networks in our marketplace and are actively rolling out more new chains to enable you to build effortlessly on a single interface while leveraging the unique tools and technologies of various blockchains.

Scalability and performance

The ability to handle high volumes of traffic and deliver swift response times is paramount in the growth of your DApp. You want to consider a provider that can ensure optimal performance and user experience regardless of where your users are based.

That is why OnFinality has invested in globally distributed nodes and multi-cloud hosting to enable fast and seamless access to our service from any region around the world, while providing redundancy and failover options in case of hardware or network failures.
