Question 1

Astar API: How to Connect to Astar Network RPC and Data Endpoints

Accepted Answer

The Astar API refers to the JSON-RPC interface for interacting with the Astar network, plus the official token and dApp staking data APIs. This guide explains the different Astar API types, how to connect using RPC endpoints, and how to choose the right infrastructure for production apps.

Question 2

How do you check Gnosis uptime and what does it mean for your dApp?

Accepted Answer

Gnosis Chain has a strong track record of network uptime, but RPC uptime is a different metric that directly affects your dApp's availability. This article explains how to monitor Gnosis network and RPC uptime, what to look for in provider status pages, and how to build resilience into your infrastructure.

Question 3

Sepolia Beacon RPC Endpoint: Chain Settings, Methods, and Debugging

Accepted Answer

A Sepolia beacon RPC endpoint exposes the consensus layer of the Ethereum Sepolia testnet, letting you query validator duties, finality, and blob data. This page covers the chain settings, common beacon API methods, and how to choose a reliable endpoint for your testnet or L2 development.

Question 4

TON JSON-RPC: Endpoint, Methods, and How to Use It

Accepted Answer

TON JSON-RPC is a JSON-RPC 2.0 interface to The Open Network, letting you query account state, run smart contract get-methods, and send transactions through a single HTTPS endpoint. This article explains the endpoint structure, common methods, authentication, and how to choose between public, managed, and dedicated TON RPC infrastructure.

Question 5

Optimism RPC Node: Endpoints, Chain Settings, and Debugging

Accepted Answer

Connect to OP Mainnet and Optimism Sepolia with the right RPC endpoint, chain settings, and debugging workflow. This reference covers public and managed options, common failure modes, and how to choose infrastructure that fits your workload.

Question 6

What is a Solana dedicated node and when should you use one?

Accepted Answer

A Solana dedicated node is a single-tenant RPC endpoint that gives your application exclusive access to a Solana node, avoiding the rate limits and noisy-neighbor effects of shared infrastructure. It's ideal for high-throughput trading bots, data analytics, and production dApps that need consistent performance. This article explains how dedicated nodes differ from shared and self-hosted options, and provides a practical decision guide to help you choose the right infrastructure for your workload.

Question 7

Solana Validator APIs: Vote Accounts, Epoch Data & Monitoring

Accepted Answer

Solana validator APIs are not a single endpoint. They fall into several categories: core JSON-RPC methods for raw network state, specialized vote-account and epoch-data APIs, and monitoring or analytics APIs that aggregate validator performance. For validator operations, start with Solana JSON-RPC methods such as getVoteAccounts, getEpochInfo, getBlockProduction, and getLeaderSchedule to query vote accounts, identity, commission, stake, and epoch progress. Use specialized APIs when you need normalized historical credit performance, skip rate, vote distance, or alerting. Public clusters like https://api.mainnet-beta.solana.com and https://api.devnet.solana.com are useful for development, but production validator workflows often need a dedicated or high-availability RPC endpoint with WebSocket support and predictable rate limits. Check current plan terms because public limits can change. Developer teams should separate raw RPC methods from specialized data APIs to avoid integration friction. OnFinality offers a Solana RPC endpoint with HTTPS/WebSocket access and archive support on mainnet; current coverage and regional availability are listed on /networks/solana.

Question 8

Shared vs Dedicated Solana RPC Cost: Pricing Models & TCO

Accepted Answer

Shared Solana RPC plans are usually consumption-based, charging by request volume, compute units, or data transfer. This keeps costs low for development, staging, and moderate production traffic because you pay primarily for what you use. Dedicated Solana RPC nodes typically carry a higher fixed monthly cost, but that cost buys reserved CPU, memory, storage, and bandwidth; predictable resource isolation; and more configuration control. The right choice depends on traffic shape, latency sensitivity, WebSocket volume, and operational overhead—not just the list price. For low or intermittent usage, shared endpoints are usually the lower total cost. For sustained high volume, heavy account indexing, real-time trading, or custom node settings, a dedicated node may have better unit economics and lower operational risk. However, exact break-even points vary by provider, method mix, and compute weighting, so teams should measure actual usage before comparing quotes. Public endpoints such as https://api.mainnet-beta.solana.com are useful for testing but are not a production cost plan. See the RPC pricing page and the Solana network page for current plan details.

Question 9

Shared vs Dedicated Solana RPC: Performance, Isolation & Scaling

Accepted Answer

Shared Solana RPC nodes are a practical entry point for development, staging, and moderate production traffic. They provide managed JSON-RPC and WebSocket access without requiring teams to operate their own infrastructure. However, because capacity is shared across tenants, performance can vary under load: response times may widen, rate limits may be enforced, and WebSocket subscriptions can become less stable when another tenant generates heavy traffic. Dedicated Solana RPC nodes reserve CPU, memory, storage, and network capacity for a single workload. This isolation usually reduces latency variance and makes throughput more predictable, which matters for trading bots, real-time dashboards, games, and high-frequency indexing. The tradeoff is cost and operational ownership: dedicated access has a higher fixed cost, and teams may need to plan monitoring and failover. The right choice depends on evidence, not guesswork. Start with shared access, measure p50/p95 latency, error rates, rate-limit hits, and WebSocket reconnects, then move to dedicated when those metrics show shared capacity is constraining your product. OnFinality offers shared Solana RPC at /networks/solana and a dedicated node path at /rpc-assistant/dedicated-solana-node.

Question 10

What is Solana Devnet and how do you use it for development?

Accepted Answer

Solana Devnet is a free, public test network where developers can deploy programs, test transactions, and simulate mainnet behavior without using real SOL. It mirrors the Solana runtime closely, making it the standard environment for building and debugging dApps before mainnet launch.

This guide covers how to connect to Devnet, get free SOL from the faucet, and choose a reliable RPC endpoint. You'll also learn how to debug transactions and decide when Devnet is the right environment for your project.

Question 11

Arbitrum Public RPC: Endpoints, Chain Settings, and Provider Selection

Accepted Answer

Arbitrum One and Arbitrum Sepolia public RPC endpoints let developers connect wallets and dApps without running a node. This article covers official endpoints, chain settings, and how to evaluate public versus managed RPC providers for production workloads.

Question 12

What are Arbitrum nodes and how should you run or access them?

Accepted Answer

Arbitrum nodes are the software clients that maintain the state of Arbitrum chains like Arbitrum One and Arbitrum Sepolia. You can run your own full or archive node to independently verify the chain, or use a managed RPC provider to get access without operating infrastructure. This guide explains node types, operational tradeoffs, and how to decide between self-hosting and using a service like OnFinality.
