Question 1

How do pay-as-you-go blockchain nodes work, and when should you use them?

Accepted Answer

Pay-as-you-go blockchain nodes are managed RPC endpoints billed by actual usage instead of a fixed monthly subscription. This model suits teams with uneven traffic, multi-chain experiments, or early-stage products because it keeps infrastructure costs aligned with demand.

Before adopting a usage-based plan, compare rate limits, overage pricing, WebSocket support, and archive data access against your projected workload. Use real traffic samples to estimate spend, and plan a path to dedicated nodes if usage becomes predictable and sustained.

Question 2

Dwellir vs Other RPC Providers: What Should You Compare?

Accepted Answer

Dwellir is a multi-chain RPC infrastructure provider that advertises access to over 150 blockchain networks. Developers commonly search for it when comparing API providers or looking for reliable HTTPS and WebSocket endpoints for Ethereum, Polkadot, Base, and other chains. This page helps you evaluate Dwellir's offerings against real production needs: chain coverage, archive data, failover behavior, and pricing transparency.

Rather than treating any single provider as a default, the decision comes down to your workload. If you need broad testnet coverage, predictable pricing, and simple failover, an RPC platform like OnFinality can be a strong alternative. Use the checklist below to compare Dwellir with other providers on the criteria that actually affect dApp reliability and cost.

Question 3

How do you choose a Stellar RPC provider for Soroban apps?

Accepted Answer

Stellar RPC gives you real-time access to Stellar network data for Soroban smart contracts, account balances, and transaction submission. Providers differ in network coverage, archive support, dedicated node access, and pricing, so the right choice depends on your app's workload.

This guide walks through what Stellar RPC is, the features to compare, and how to test provider performance before committing. It also covers common pitfalls like relying on RPC for historical data or using the wrong network for a given task.

Question 4

How reliable is Moonbeam RPC uptime and what should you monitor?

Accepted Answer

Moonbeam RPC uptime determines whether your dApp can read chain state, submit transactions, and stay responsive during traffic spikes. This page explains what uptime claims actually cover, how to verify them with your own monitoring, and how to choose RPC infrastructure that matches your reliability needs.

Question 5

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 6

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 7

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 8

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 9

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 10

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 11

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 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.
