The recent Hong Kong Web3 conference has significantly boosted activity within the blockchain industry. As Web3 continues to evolve, a new wave of innovative projects is emerging. For developers creating decentralized applications (DApps), accessing a reliable blockchain node to host smart contracts is essential. However, this process can be complex and time-consuming, especially for those new to Web3.
This is where blockchain node service providers come into play. Companies like Tokenview, Infura, Alchemy, and QuickNode simplify node access by offering remote blockchain services without the need for personal node setup—saving both time and resources. This guide compares these four popular providers based on API services, documentation, pricing, supported public chains, and additional features to help developers choose the best fit for their needs.
Overview of Providers
Tokenview
Tokenview is an established blockchain development team that has operated since 2017. They maintain over 120 blockchain explorers and possess deep expertise in the underlying technologies of major public chains.
Their node services support BTC, ETH, and TRON, enabling dApp development across these three distinct protocols. Users frequently praise Tokenview for exceptional stability. The data provided aligns with their blockchain explorers, ensuring high accuracy and real-time performance.
Infura
Founded in 2016 and later acquired by ConsenSys (MetaMask’s parent company), Infura specializes in Ethereum-based infrastructure. It supports 10 Ethereum Layer 1 and Layer 2 chains and recently added IPFS API capabilities for decentralized file storage and access.
Alchemy
Alchemy is a blockchain scaling platform that allows developers to securely build, test, and monitor decentralized applications (DApps). It offers a comprehensive Web3 toolkit, including network connectivity and node management endpoints. Alchemy also supports testnets for developer debugging and testing.
QuickNode
Since 2017, QuickNode has focused on building a Web3 cloud platform that enables developers to create blockchain applications with instant global JSON-RPC access to on-chain data. They operate nodes worldwide and are trusted by numerous blockchain projects for supporting ecosystem growth.
API Services Comparison
Beyond basic node access, blockchain node service providers often offer specialized data services tailored to different needs:
- RPC Node Service: Provides foundational infrastructure for blockchain or DApp developers. It allows remote node access via global JSON-RPC to retrieve on-chain data, eliminating the need to maintain personal nodes.
- Archive Data API: Also known as archival nodes, these store the complete historical state of the blockchain at every block height. Accessing historical data through Archive APIs is invaluable for developers, but the complexity, technical challenges, and maintenance costs are high. Among the providers discussed, only Tokenview currently offers this service.
- Webhook Transaction Notifications: Enables real-time alerts for blockchain activities like cryptocurrency or token transfers. Users can monitor specific accounts or track whale movements efficiently.
- NFT API: Offers NFT data services for developers in the NFT and Web3 space, supporting the creation of innovative applications and projects.
- NFT Subscriptions: Tracks on-chain NFT transactions through four subscription models: Account, Token, Collection, and Event. This service pushes real-time NFT activities to users seamlessly.

Supported Public Chains
Each provider supports different public chains, affecting their suitability for various projects:
- Tokenview: RPC node services support ETH, TRX, and BTC—chains with entirely different underlying technologies. They are also integrating EVM, BTC-series, and other public chain nodes. Their Archive Data API covers 120+ chains, including BTC-series, ETH-series, and Layer 2 networks, setting them apart with exclusive data offerings.
- Infura: Primarily supports Ethereum mainnet and testnets like Rinkeby, Goerli, Kovan, and Ropsten. Limited Layer 2 support is available.
- Alchemy: Supports 7 public chains via RPC node services, including testnets for each.
- QuickNode: Offers RPC node services for 19 public chains and their respective testnets.
Development Documentation
Clear documentation is crucial for developer productivity:
- Tokenview: Provides documentation in both English and Chinese.
- Infura: Documentation is available in English.
- Alchemy: English-only documentation.
- QuickNode: English-only documentation.

Pricing Models
All four providers—Tokenview, Infura, Alchemy, and QuickNode—offer free tiers and customizable plans for specific needs. Tokenview and QuickNode allow users to purchase additional requests. Note that Alchemy uses Compute Units (CU) to measure API resource consumption. Simple requests like blockNumber cost 10 CU, while complex calls like eth_call consume 26 CU.
Developers typically choose services based on scenario requirements, feature compatibility, and pricing. Given the vastness of blockchain data and the need for fault tolerance, using multiple providers for comparison and redundancy is often wise.
Frequently Asked Questions
What is a blockchain node service provider?
A blockchain node service provider offers remote access to blockchain nodes, allowing developers to interact with networks without maintaining their own infrastructure. This saves time, reduces costs, and simplifies DApp development.
Why is Archive Data important?
Archive Data provides access to historical blockchain states at every block height. This is essential for auditing, analytics, and applications requiring comprehensive historical data, but it is resource-intensive to maintain.
How do I choose the right node provider?
Consider factors like supported chains, API features (e.g., Archive Data, Webhooks), documentation clarity, pricing, and reliability. Testing multiple providers during development can help identify the best fit.
Can I use multiple node providers simultaneously?
Yes, many developers use several providers to ensure redundancy, improve reliability, and access unique features like Tokenview’s Archive API or specialized NFT services.
What are Compute Units (CU) in Alchemy’s pricing?
Compute Units measure the computational resources consumed by API calls. Simpler requests use fewer CUs, while complex operations require more, affecting overall costs.
Do these providers support testnets?
Yes, most providers, including Alchemy, Infura, and QuickNode, offer testnet support for development and testing purposes. Tokenview also provides testnet options for supported chains.
