Solana Endpoint: How to Connect to Solana RPC for Production Apps
A Solana endpoint is the URL your dApp or backend uses to send JSON-RPC requests to the Solana network. Choosing the right endpoint affects latency, reliability, and how well your ...
Can you recommend Solana RPC services that offer enhanced APIs for NFT data?
Yes. For Solana NFT data, you need RPC services that go beyond standard JSON-RPC and provide specialized endpoints for metadata, compressed NFTs (cNFTs), and asset indexing. This a...
Avalanche RPC Node: Endpoint Settings, Provider Options, and Debugging
An Avalanche RPC node exposes the C-Chain's Ethereum-compatible JSON-RPC API, letting dApps read and write on-chain data. This article covers endpoint configuration, provider selec...
Arbitrum Endpoint: Chain Settings, RPC URLs, and Debugging
This page explains what an Arbitrum endpoint is, how to connect to Arbitrum One and Arbitrum Sepolia, and how to choose between public RPC, dedicated nodes, and API services. It co...
Solana RPC Providers with Advanced Indexing Features: What to Look For
Advanced indexing features in Solana RPC providers go beyond basic transaction fetching, enabling efficient querying of historical data, token balances, and program state. This art...
What dedicated node access features should Solana developers look for?
Dedicated Solana RPC nodes give your dApp exclusive access to a single node instance, avoiding the noisy-neighbor effects of shared endpoints. Key features to evaluate include dedi...
What Is a Solana Free API and How Do You Use It?
A Solana free API lets developers read and write to the Solana blockchain without paying for node infrastructure. Public endpoints are great for prototyping, but they often have ra...
What is the Scroll endpoint and how do I connect to it?
The Scroll endpoint is the JSON-RPC API for the Scroll Ethereum Layer 2 network. This page explains what the Scroll endpoint is, how to configure your wallet or dApp, and how to ch...
What is the SORA API and how do you use it for dApps?
The SORA API refers to the RPC endpoints and JSON-RPC methods that let applications read and write data on the SORA network. This article explains what the SORA API is, how to conn...
What is a Starknet node and how do you run or connect to one?
A Starknet node is software that syncs with the Starknet network, validates state transitions, and serves JSON-RPC requests for dApps and indexers. Running a full node gives you di...
What is an Ethereum API service and how do you choose one?
An Ethereum API service gives your dApp, indexer, or backend a reliable way to read and write blockchain data without running your own node. These services expose JSON-RPC endpoint...
What is Crust Network and how does it provide decentralized storage?
Crust Network is a Substrate-based layer 1 blockchain that adds an incentive and service layer to IPFS, enabling decentralized, verifiable, and permanent storage. It offers an on-c...
