RPC documentation entries
Explore practical RPC guides for developers, builders, and teams creating reliable Web3 applications and growing blockchain ecosystems with OnFinality.
Can you recommend a Solana RPC provider that fits a startup budget while staying production-ready?
Yes. The practical answer for most early-stage teams is to start on a shared or pay-as-you-go Solana RPC plan that includes WebSocket support and predictable request pricing, then ...
Free Solana API: What You Actually Get and When to Move On
A free Solana API gives you an HTTP and WebSocket endpoint that speaks Solana's JSON-RPC methods, so you can read accounts, send transactions, and subscribe to logs without running...
How to Mine Solana: Why You Can't, and What to Do Instead
Solana does not use proof-of-work mining, so there is no way to mine SOL with GPUs or ASICs. The network runs on a proof-of-stake plus proof-of-history model where validators stake...
What RPC provider selection criteria matter most for a Solana dApp?
Solana dApps put unusual pressure on RPC infrastructure: high request volume, frequent account and program reads, WebSocket subscriptions, and bursts around transactions and market...
How do I monitor Solana validator uptime with an API endpoint?
Solana validator uptime is not exposed through a single dedicated uptime endpoint. Instead, you derive it by polling standard Solana JSON-RPC methods such as getVoteAccounts, getSl...
What makes a Solana validator-as-a-service provider reliable for production workloads?
Solana validator-as-a-service providers run Solana node infrastructure on your behalf, but the term is often used loosely. Some providers focus on staking and consensus participati...
Solana HTTP API: How Do You Connect, Sign, and Debug JSON-RPC Calls?
The Solana HTTP API is the JSON-RPC interface your app uses to read accounts, submit transactions, and query the cluster over standard HTTPS. You send a POST request with a JSON bo...
What Is a Solana Devnet Address and How Do You Use One?
A Solana devnet address is a public key on the Solana devnet cluster, a test network that mirrors mainnet behavior without using real SOL. You use it to airdrop test SOL, deploy pr...
Which Solana RPC services offer enhanced APIs tailored for NFT and DeFi data?
Most Solana RPC providers expose the same core JSON-RPC surface, so the real differentiator for NFT and DeFi workloads is how well a provider handles token accounts, program logs, ...
How do Solana NFT API providers handle scalability and low-latency data retrieval?
Solana NFT applications depend on fast, consistent access to on-chain state: token accounts, metadata pointers, mint authorities, and compressed NFT proofs. The bottleneck is rarel...
Solana Devnet RPC: Endpoint Settings, Airdrops, and Debugging
Solana devnet is the testing cluster where you validate programs, transactions, and client code before touching mainnet. This page explains how to connect a Solana devnet RPC endpo...
How do I choose reliable Solana RPC providers for NFT data APIs?
NFT data APIs on Solana depend on RPC calls that are heavier than simple transfers: token account lookups, metadata reads, compressed NFT proofs, and log subscriptions. The provide...
