Blockchain needs more than digital coins and trading platforms to work at scale. Underneath every application sits a technical base that has to process transactions, store data, connect networks, and keep developers supported. That’s the job of blockchain infrastructure providers. Companies like Alchemy, QuickNode, Infura, Chainstack, and Ankr let businesses build and run blockchain products without handling every technical piece themselves.

1. Alchemy

Alchemy is one of the biggest names in blockchain infrastructure, and it works with developers, startups, and large businesses alike. The platform covers blockchain nodes, Remote Procedure Call (RPC) APIs, webhooks, wallet tools, and blockchain data access. Its published network directory lists more than 100 chains. What sets it apart is the sheer range of developer tools and the number of networks it supports. Web3 startups, decentralized apps, exchanges, and enterprise teams all use it to build and manage their products.

2. QuickNode

QuickNode connects you to blockchains through RPC endpoints, dedicated nodes, WebSockets, data streams, and add-on services. Its published comparison lists 79 chains. Speed and dependable data delivery are what the company is known for, and its managed nodes spare businesses the cost and hassle of running their own servers. If you’re building a DeFi platform, a crypto exchange, a blockchain game, or any high-traffic app, QuickNode can handle the network requests and serve up real-time data.

3. Infura

Infura, a Consensys product, is a familiar name to most Ethereum developers. It provides blockchain nodes and RPC APIs so applications can talk to supported networks, and its published comparison lists 23 chains. It also supports the Decentralized Infrastructure Network (DIN), an effort to open up Web3 infrastructure to more people. Ethereum apps, crypto wallets, and individual developers use Infura to read blockchain data and send transactions without running a node of their own.

4. Chainstack

Chainstack offers managed blockchain nodes, RPC access, dedicated nodes, and data indexing tools across more than 70 chains. It’s clearly built with enterprises in mind, and customers get a choice of cloud-based node deployment. Its Warp service is designed to make transactions faster. If your business wants real control over node access and network setup, Chainstack is worth a look, particularly for enterprise blockchain apps, fintech products, and teams working across several networks.

5. Ankr

Ankr provides blockchain RPC services, APIs, staking tools, and validator infrastructure, with published coverage of 80 chains. Decentralized infrastructure is central to what it does, and developers can reach many networks from a single platform. It also works with projects that need staking and validator services. DeFi apps, multichain products, and Web3 developers use it to connect to blockchain networks and pull onchain data.

6. dRPC

dRPC is all about decentralized RPC services and network access. Its published comparison lists 135 chains, among the widest ranges in this group. Rather than leaning on one operator, the platform spreads requests across multiple infrastructure providers and routing systems. So if one provider runs into trouble, your application can keep working. Businesses that want multichain support, backup access, and steady RPC service should consider it.

7. GetBlock

GetBlock offers shared and dedicated blockchain nodes, RPC APIs, and network access for businesses, across more than 130 chains. Its dedicated nodes are a real strength, because they give customers more control over how their infrastructure is set up. It also offers Blockbook-based data access. Crypto exchanges, fintech companies, wallets, and payment platforms can connect to blockchain networks through GetBlock without maintaining a separate node system for every chain.

8. Blockdaemon

Blockdaemon is made for institutions. It offers validator nodes, staking, RPC APIs, and enterprise node operations. Its published node comparison lists 23 chains, and its staking services cover more than 50 protocols. Banks, digital asset custodians, funds, and other financial institutions are its main customers. Validator operations and institutional staking are where it really shines, helping large businesses join proof-of-stake networks while keeping technical risk and node operations under control.

9. Helius

Helius goes deep on Solana, giving developers building on that network a focused set of tools. These include Solana RPC, enhanced APIs, LaserStream, and transaction delivery tools. Where other providers spread across many chains, Helius sticks to one major ecosystem, which works well for apps that need detailed Solana data and fast transaction access. DeFi platforms, trading products, NFT projects, and other Solana apps use it to get at network data and power their core services.

10. NOWNodes

NOWNodes provides blockchain nodes, RPC access, and indexed blockchain APIs, with published coverage of more than 120 chains. Wide network access is the main idea, and its customers include wallets, exchanges, payment platforms, and other blockchain businesses. Its Blockbook-based services also make blockchain data easier to reach. It’s a good match for companies that would rather connect to many networks through one provider than juggle separate node setups for each chain.

A Market That Needs More Than Node Access

These providers now compete on network coverage, data access, security, staking, and enterprise support. Recent updates also show how much regular upgrades matter. QuickNode completed a Solana Mainnet upgrade to Agave 4.4.0 and Yellowstone gRPC v17 on November 6, 2026. Alchemy fixed an RPC latency issue on November 8, and QuickNode and Blockdaemon scheduled network upgrades for November 9. If your business depends on stable blockchain access, this kind of maintenance matters.

Each provider has its own role. Alchemy and QuickNode offer broad developer services, Infura leans toward Ethereum, and Helius serves Solana apps. Chainstack and GetBlock provide managed and dedicated nodes, while Blockdaemon focuses on institutions. Ankr and dRPC bring decentralized RPC options, and NOWNodes covers a wide range of networks. Which one is right for you depends on the chains you need, what the service costs, your data requirements, and how much technical control you want. Choose well, and you can build reliable blockchain products without paying to run all the infrastructure yourself.
