Question 1

Solana RPC API Documentation: Endpoints, Methods, and Debug Path

Accepted Answer

Solana's RPC API is the JSON-RPC interface your app uses to read accounts, submit transactions, and subscribe to on-chain events. This reference walks through the endpoint shape, the method groups you will actually call, and how to debug the errors that show up in production.

It also covers when a public endpoint is enough and when a dedicated Solana node from OnFinality makes more sense for consistent throughput, WebSocket subscriptions, and heavier read workloads.

Question 2

What is a Smart Chain RPC URL and how do I connect to BNB Smart Chain?

Accepted Answer

A Smart Chain RPC URL is the HTTP or WebSocket endpoint your wallet, dApp, or backend uses to read BNB Smart Chain state and broadcast transactions. It carries JSON-RPC calls such as eth_blockNumber, eth_getBalance, and eth_sendRawTransaction to a node that is synced with the network.

This page covers the BNB Smart Chain mainnet and testnet settings you need for wallet configuration, gives a working curl and JavaScript example, and explains when a public endpoint is enough versus when a managed RPC API or dedicated node is the better fit for production traffic.

Question 3

Scalable Solana gRPC Endpoints for Enterprise Use: What to Evaluate

Accepted Answer

Solana's gRPC interfaces (Geyser plugin streams and the Yellowstone-style gRPC proxy) push account, slot, block, and transaction updates to your backend instead of forcing you to poll JSON-RPC. For enterprise workloads, the hard part is not finding a gRPC endpoint but finding one that scales with your subscriber count, keeps streams stable during congestion, and gives you a clear path to dedicated capacity when shared limits are not enough.

This article explains how Solana gRPC streaming differs from standard RPC, what to check before you commit to a provider, and how to combine a scalable gRPC stream with reliable JSON-RPC and WebSocket endpoints. OnFinality offers Solana RPC API access and dedicated node infrastructure, so you can start on shared endpoints and move to isolated capacity as your indexing or trading volume grows.

Question 4

BNB RPC List: Which Endpoints Should Your App Connect To?

Accepted Answer

A BNB RPC list is only useful if you know which endpoint type fits your workload. This page breaks BNB Smart Chain endpoints into public, managed, and dedicated categories, then shows the chain settings, request formats, and failure modes you need before wiring anything into production.

You get the exact mainnet and testnet connection details, a curl and viem example, and a short evaluation path for deciding when a shared endpoint is enough and when a dedicated BNB node is the better fit.

Question 5

Acala Liquid Staking: How LDOT Works and What to Check Before You Stake

Accepted Answer

Acala liquid staking lets you deposit DOT into Acala's staking module and receive LDOT, a transferable derivative token that keeps earning staking rewards while you use it elsewhere in DeFi. This article explains how the flow works, what LDOT represents, and the RPC and API surface you need to read staking state or build a liquid staking integration. It also covers the operational questions developers hit first: which endpoints to use, how to query exchange rates and unbonding state, and when a shared public endpoint is enough versus when a dedicated node fits better.

Question 6

Polygon Public RPC: When to Use It and When to Move On

Accepted Answer

A Polygon public RPC is a shared, no-auth HTTPS endpoint that lets you read chain data and send transactions without running your own node. It is ideal for quick tests, wallet setup, and low-volume scripts, but shared capacity means you should not rely on it for production traffic or strict latency targets. This article covers the official public endpoint, chain settings, request examples, rate-limit symptoms, and the point at which a dedicated or managed RPC becomes the better choice.

Question 7

Sui JSON-RPC: Methods, Endpoints, and How to Use Them

Accepted Answer

Sui JSON-RPC is the standard interface for interacting with the Sui blockchain, enabling developers to query chain data, submit transactions, and subscribe to events. This article explains the core methods, how to connect to Sui endpoints, and common pitfalls to avoid when building on Sui.

Question 8

PublicNode Solana RPC Endpoint: How to Connect and What to Expect

Accepted Answer

PublicNode offers free Solana RPC endpoints for developers who want to test applications without committing to paid infrastructure. This article explains how to find and use the PublicNode Solana RPC endpoint, what rate limits and reliability to expect, and when to move to a managed or dedicated RPC provider like OnFinality for production workloads.

Question 9

What Is Kilt Mashnet and How Do You Connect to It?

Accepted Answer

Kilt Mashnet is the permissionless mainnet of the Kilt blockchain, designed for decentralized identity (DID) and verifiable credentials. This article explains what Mashnet is, how it differs from the Kilt Peregrine testnet, and how to connect your dApp or wallet to the network using RPC endpoints.

You'll find the official chain settings, configuration examples for common tools, and guidance on choosing an RPC provider for production traffic. Whether you're building identity solutions or just need a reliable endpoint, this page helps you get started quickly.

Question 10

What Is a Gnosis Node and How Do You Connect to Gnosis RPC?

Accepted Answer

A Gnosis node is a client that validates and serves data for the Gnosis chain, an EVM-compatible network focused on stablecoin payments. Most developers don't need to run one: managed RPC endpoints provide reliable access to the chain without the overhead of syncing and maintaining infrastructure. This article explains what Gnosis nodes do, how to connect to Gnosis RPC, and how to choose between running your own node or using a managed service.

Question 11

How do I use the Solana explorer API to inspect transactions and accounts?

Accepted Answer

The Solana explorer API is the JSON-RPC interface that powers block explorers and lets developers query transactions, accounts, and blocks. This article explains how to use it for debugging and analytics, and how to choose a reliable RPC provider for production workloads.

Question 12

Polygon RPC List: Mainnet and Amoy Endpoints for Developers

Accepted Answer

Find the official Polygon RPC endpoints for mainnet and Amoy testnet, including HTTPS and WebSocket URLs. Learn how to choose between public, managed, and dedicated RPC providers based on your application's needs, and get configuration examples for wallets and developers.
