Question 1

What is the best JSON-RPC API provider for blockchain projects?

Accepted Answer

Choosing a JSON-RPC API provider is a critical infrastructure decision for any blockchain project. The best provider depends on your specific workload, chain requirements, and budget. This article outlines the key evaluation criteria—from method support and data access to pricing models and failover strategies—to help you make an informed choice.

Question 2

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

Accepted Answer

A dedicated TON node is a full or archive node deployed exclusively for your project, giving you a private RPC endpoint with isolated compute resources. This article explains the difference between shared and dedicated nodes, when to choose a dedicated setup, and how to evaluate providers for production workloads.

Question 3

What is an Abstract RPC provider and how do you evaluate one?

Accepted Answer

An Abstract RPC provider gives your dApp a JSON-RPC endpoint to the Abstract Layer 2 network, which is a zero-knowledge rollup built on the ZK Stack. Providers handle node operation, load balancing, and API access so you can focus on building. This article explains what to look for in an Abstract RPC provider, how to compare options, and how to connect your app.

Question 4

How to Choose a Kaia RPC Provider for Production Apps

Accepted Answer

Choosing a Kaia RPC provider means balancing reliability, latency, data access, and pricing against your app's traffic patterns. Public endpoints are fine for prototyping, but production apps often need a managed provider with higher rate limits, WebSocket support, and archive data. This guide walks through the key criteria and common pitfalls so you can pick infrastructure that won't break under load.

Question 5

Base RPC Providers: Public, Managed & Dedicated Options

Accepted Answer

Base RPC providers fall into three broad tiers: public endpoints, shared managed endpoints, and dedicated nodes. Public access, including OnFinality’s public Base endpoint, is convenient for experiments and smoke tests but is rate-limited shared infrastructure and not suitable for production. Shared managed access adds API-key enforcement, higher capacity, clearer request limits, and optional archive or Trace support, making it appropriate for many development, staging, and moderate production workloads. Dedicated Base nodes isolate your traffic, provide custom configuration, and offer stronger monitoring for high-volume or business-critical applications. Before choosing, confirm support for Base mainnet chain ID 8453 and Base Sepolia chain ID 84532, verify archive or Trace availability, check WebSocket transport, test latency from your deployment regions, and review current plan limits, pricing, and support tiers. The most useful comparison is workload fit: how consistently the endpoint behaves under your read, write, subscription, and historical-query patterns, and whether a clear upgrade path exists as demand grows.

Question 6

Fastest Solana RPC: How to Measure Latency & Endpoint Performance

Accepted Answer

Fastest Solana RPC is not a single endpoint; it depends on workload, region, and the methods you call. Latency comes from network round-trip time, server processing, and payload size. A provider with a nearby node and well-tuned hardware may show excellent p50 latency for light reads like `getSlot`, but p95 for heavy methods like `getProgramAccounts` can spike under load. To choose an endpoint, measure from your application's region, test the specific JSON-RPC methods your dApp uses, and track tail latency (p95, p99) rather than averages. Also evaluate WebSocket subscription stability and rate-limit behavior; throttling and retries add perceived delay. Public endpoints like `https://api.mainnet-beta.solana.com` are useful for development but have shared capacity and limits that can change. For production, a managed Solana RPC endpoint or dedicated node can provide more predictable latency. OnFinality offers Solana endpoints (verify current plan details on the [Solana network page](/networks/solana)), but always benchmark against your own workload before committing. A reproducible test suite that captures p50/p95, method-specific response times, WebSocket reconnects, and rate-limit headroom gives you the only reliable comparison.

Question 7

Best Solana APIs for Validators: Monitoring, Data & Operations

Accepted Answer

Best Solana APIs for validators are rarely one product. Validator operators need a small set of purpose-built interfaces: monitoring APIs that expose vote-account and skip-rate telemetry, analytics APIs for epoch-level performance and rewards, RPC endpoints for transaction submission and chain state, and reporting APIs for historical or exported data. The right combination depends on whether you run one validator or a fleet, and whether you need live alerting, historical reporting, or both. Start by mapping the operational jobs—slot health, vote distance, leader slots, stake account changes, reward accrual—to the API categories that actually cover them. Then compare providers on data freshness, authentication, retention windows, and failover behavior. Do not assume that a generic Solana RPC provider or a public endpoint will give you the vote-account and epoch-level detail a validator needs. For production validator operations, a dedicated or reliable shared RPC layer plus a monitoring/data API is often a more practical baseline than a single 'best' API.

Question 8

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 9

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 10

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 11

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.
