Question 1

Kaia Public Node: Endpoints, Providers, and Production Considerations

Accepted Answer

Kaia public nodes let you interact with the Kaia mainnet and Kairos testnet without running your own endpoint node. This article covers the official public endpoints, how to choose a reliable RPC provider, and what to consider for production workloads.

Question 2

How to Choose a Sui Node Provider for Production Apps

Accepted Answer

Choosing a Sui node provider means balancing throughput, reliability, and cost for your specific workload. This guide explains what to look for in a provider, including gRPC support, archive data, and failover strategies, and how to evaluate options for production Sui applications.

Question 3

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 4

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 5

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 6

What is Solana deadnet and how do you avoid it?

Accepted Answer

Solana deadnet is a community term for deprecated or non-functional Solana network environments, often confused with devnet or testnet. This article clarifies what deadnet means, how it differs from active clusters, and how to choose reliable RPC endpoints for development and testing.

Question 7

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 8

How to Choose a Fantom RPC Provider for Production Apps

Accepted Answer

Choosing a Fantom RPC provider means balancing latency, reliability, and cost against your app's needs. This guide explains what to look for in a provider, how to evaluate endpoints, and when a dedicated node makes sense. OnFinality offers a public Fantom endpoint and dedicated infrastructure options to support your deployment.

Question 9

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 10

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.

Question 11

What is SORA Network?

Accepted Answer

SORA is a blockchain network focused on creating a decentralized monetary system. It uses the XOR token and on-chain governance to let token holders decide how to allocate resources. The network is evolving into SORA Nexus, built on Hyperledger Iroha 3, aiming for fast finality and interoperability for CBDCs and DeFi. For developers, accessing a reliable RPC endpoint is key to building on SORA.

Question 12

What is the Solana Devnet RPC endpoint and how do you use it?

Accepted Answer

Solana Devnet is a public test cluster for building and testing Solana programs without risking real funds. Its official public RPC endpoint is https://api.devnet.solana.com, but public endpoints are rate-limited and shared, so serious development often uses a managed RPC provider like OnFinality for higher limits and reliability. This article explains the endpoint, how to connect, common pitfalls, and when to move to a dedicated endpoint.
