Question 1

How do I evaluate the best blockchain JSON-RPC API solutions?

Accepted Answer

A blockchain JSON-RPC API gives your dApp read/write access to a network without running a full node. But not all providers are equal—latency, archive support, WebSocket availability, and pricing models vary widely. This article breaks down the evaluation criteria every developer should check before choosing an RPC API provider for production.

Question 2

How to Find the Most Reliable Optimism RPC Provider

Accepted Answer

Looking for the most reliable Optimism RPC provider? Reliability goes beyond stated uptime percentages. This guide covers key metrics like latency distribution, sync health, archive and trace API support, and failover capabilities. Use the decision checklist to compare providers objectively and avoid common pitfalls that cause production outages.

Question 3

How do I choose an RPC provider for NFT projects?

Accepted Answer

NFT applications—minting platforms, marketplaces, and gaming tools—depend on fast, reliable RPC endpoints to submit transactions and fetch metadata. The wrong provider can cause failed mints, slow loads, and poor user experience. This guide covers the key criteria for evaluating RPC providers for NFT workloads, including latency, rate limits, archive data support, and failover capabilities. We also walk through a practical setup example using the Solana network and compare shared vs dedicated node access for high-traffic NFT drops.

Question 4

How to Evaluate Optimism RPC Providers for Reliability in Production Apps?

Accepted Answer

When selecting an Optimism RPC provider, reliability goes beyond uptime. This article covers the key criteria to evaluate: endpoint consistency, archive access, WebSocket stability, failover design, and geographic latency. Use the checklist below to compare providers and choose the best infrastructure for your Optimism dApp.

Question 5

Dedicated Polygon Node: Infrastructure Considerations for Production dApps

Accepted Answer

Learn when a dedicated Polygon node is necessary for production dApps, how it compares to shared endpoints, and what criteria to use when evaluating providers. This article covers architectural tradeoffs, cost factors, and operational considerations.

Question 6

Reliable Solana RPC for Staking Backends

Accepted Answer

Reliable Solana RPC for staking backends is built from predictable transaction submission, clean separation of read-heavy account queries from write-heavy delegation and withdrawal flows, and active health monitoring. A staking backend should not treat a single RPC endpoint as a black box. Instead, it should split reads and writes to different endpoints or at least different connection pools, monitor latency and error rates per method, and retry only idempotent calls such as `getBlockHeight`, `getBalance`, or `simulateTransaction`. For transaction submission, use idempotent nonce-aware retries or reconcile on-chain state after a timeout instead of blindly resending. Plan capacity around `getProgramAccounts` and `getVoteAccounts` cost rather than average reads per second. Keep a controlled fallback provider, but avoid automatic failover for write paths until the primary has failed health checks for a sustained period. OnFinality provides Solana HTTPS and WebSocket endpoints with archive support for mainnet and regions like N. Virginia and Hong Kong, but verify current plan details. Use Devnet for staging with test SOL from https://faucet.solana.com, then reproduce the same connection patterns on mainnet. This page outlines the operational patterns that keep staking backends stable.

Question 7

Mantle RPC Provider Evaluation: Key Criteria for Production Deployments

Accepted Answer

Choosing a Mantle RPC provider for production requires evaluating reliability, latency, archive data support, and pricing. This article covers the essential criteria and decision checklist for developers.

Question 8

Which RPC provider supports the widest range of blockchains?

Accepted Answer

RPC providers differ significantly in the number of blockchain networks they support, but raw network count is only part of the story. OnFinality offers access to over 100+ networks including Ethereum, Solana, Polkadot, BNB Chain, and many testnets, with both shared and dedicated node options. Focus on providers that offer deep support (archive, trace, WebSocket) for the chains you actually need, not just the longest list.

Question 9

How to Choose a Polkadot RPC Provider for Production dApps

Accepted Answer

Choosing the right Polkadot RPC provider is critical for production dApps, parachains, and cross-chain services. You need to evaluate endpoint reliability, archive data support, latency, and pricing to match your workload. OnFinality offers scalable Polkadot RPC endpoints with archive and trace support, dedicated node options, and transparent pricing to help you build and scale efficiently.

Question 10

Solana Staking API: RPC Methods for Staking Integrations

Accepted Answer

Solana staking integrations rely on core JSON-RPC methods to query stake accounts, validator vote accounts, epoch state, and to build and submit staking transactions. The most important methods are getStakeActivation (stake account lifecycle state), getVoteAccounts (validator and commission data), and getEpochInfo (epoch progress and timing). Production staking dApps typically extend this with simulateTransaction for preflight checks, getLatestBlockhash for transaction construction, sendTransaction for submission, and WebSocket account subscriptions for activation monitoring. Public endpoints such as https://api.mainnet-beta.solana.com and https://api.devnet.solana.com are useful for development, but rate limits and shared capacity make them unsuitable for user-facing staking features. Teams should evaluate RPC providers on support for these methods, clear commitment behavior, archive access for historical stake data, and whether the plan includes the Solana networks you need. Use the Solana devnet faucet at https://faucet.solana.com to obtain test SOL for integration testing before moving to mainnet.

Question 11

What to Look for in a Dedicated Node as a Service Provider

Accepted Answer

Dedicated nodes as a service (DNaaS) provide exclusive, managed blockchain infrastructure for a single project, eliminating resource contention and offering full control over node configuration. When evaluating providers, focus on supported chains, performance guarantees, customization options, and operational support to ensure your Web3 application gets the reliability it needs without the overhead of self-hosting.

Question 12

Best Crypto Bridge API: What Should Developers Evaluate Before Integrating?

Accepted Answer

A crypto bridge API provides a programmatic interface for moving assets or data across blockchains. While many services offer bridge APIs, their performance and reliability depend heavily on the underlying RPC infrastructure. This article outlines the key criteria developers should consider when choosing a bridge API, with a focus on how RPC endpoint quality impacts bridge operations. We'll also discuss how OnFinality's RPC services can support bridge infrastructure needs.
