Question 1

What is an RPC provider in crypto?

Accepted Answer

An RPC provider in crypto offers access to blockchain nodes that allow decentralized applications (dApps) to interact with blockchains through RPC (Remote Procedure Call) requests. Instead of running their own nodes, developers can connect via an RPC endpoint to send transactions, execute smart contracts, and fetch blockchain data. This saves time, reduces infrastructure costs, and provides stability through managed DevOps and tech support.

Question 2

How to measure RPC node provider performance?

Accepted Answer

RPC node performance is typically evaluated using metrics such as latency, uptime, and RPC success rate. Developers can run benchmark tests for one hour using tools like Prometheus, Grafana, or Apache JMeter to record response times and error rates. Geo distribution and security tools (like MEV protection) also affect performance, so it’s important to measure several parameters before choosing a provider.

Question 3

How much does an RPC cost?

Accepted Answer

RPC pricing usually depends on usage measured in compute units (CUs) or API credits, which represent the computational cost of blockchain requests. Plans typically start from around $5 to $50 per month, depending on the provider and the included request volume. Some providers, like dRPC or Ankr, also offer pay-as-you-go models, while GetBlock and others use CU-based subscriptions for precise resource tracking.

Question 4

Is a free RPC safe for production?

Accepted Answer

Free RPC endpoints are suitable for testing or small projects but not ideal for production. They often come with limited request volumes, slower speeds, and lower reliability, which can lead to downtime or failed transactions. For any commercial or high-traffic application, it’s safer to use a paid RPC plan that guarantees uptime, support, and dedicated performance.

Question 5

What is the fastest Solana node?

Accepted Answer

According to performance data, Helius provides some of the fastest Solana RPC nodes, with latency ranging between 10–80 milliseconds. It’s built specifically for Solana and maintained by experienced developers who optimize for network speed, validator integration, and analytics. While other providers may support Solana, Helius remains the most performance-focused for this chain.

Question 6

What are the computing units (CUs) of RPC providers?

Accepted Answer

Computing units (CUs) represent how much computational power an RPC method consumes when interacting with the blockchain. Each blockchain operation—such as sending a transaction or reading contract data—costs a certain number of CUs. This system helps providers calculate usage more precisely than request counts, ensuring users only pay for the actual computing effort involved.

Question 7

Which RPC providers offer the most available chains?

Accepted Answer

The provider with the widest chain coverage is dRPC, supporting over 150 blockchains through its decentralized network of independent node operators. GetBlock follows closely with access to 100+ blockchains, making it one of the top multi-chain options. A broad chainlist is crucial for cross-chain dApps and developers who work with multiple ecosystems.
