Overview
Quicknode is a blockchain development platform that provides fast, reliable APIs and tools to make building in web3 simple and seamless.
Modern applications are already complex, combining front-end interfaces, back-end services, databases, and APIs. Adding blockchain into the mix introduces new challenges, from managing nodes to handling on-chain data.
Quicknode removes that complexity by offering a unified platform that connects your app to leading blockchain networks in minutes.
Quicknode's product suite covers blockchain reads and writes, real-time data delivery, indexed and historical data, onchain trading, and decentralized storage. The sections below follow the same grouping you will find in the product menu and in your dashboard.
Infrastructure
Core RPC API
With the Quicknode Core API, you gain access to a globally distributed network of nodes that lets you interact with blockchains without managing your own infrastructure. Quicknode handles the heavy lifting so you can focus on building your application.
The Core API supports both read and write operations through HTTPS and WebSocket endpoints, providing RPC, REST, and gRPC access depending on the blockchain network.

Dedicated Clusters
Dedicated Clusters give you a backend of nodes reserved for your workload alone, with redundancy across regions. Because nothing else shares that capacity, throughput and latency stay predictable, which matters for mission-critical or spiky traffic.
Resources
Validator as a Service
Validator as a Service runs validators on your behalf. Quicknode operates the hardware, monitoring, and upgrades under an SLA, so your team gets validator uptime without taking on node operations. White-label support is available for teams that need to run validators under their own brand.
Resources
Endpoint Add-ons
Endpoint add-ons extend an endpoint you already have with capabilities like fee estimation, transaction broadcasting, MEV protection, and risk scoring. Solana Priority Fee API, Single Flight RPC, and Multi-region Transaction Broadcast are common starting points.
Add-ons come in a few shapes: RPC add-ons you call directly from your endpoint, REST add-ons that expose their own API, and external add-ons that run as standalone products.

Real-Time Data
Streams
Streams makes it simple to capture, process, and deliver historical and real-time blockchain data to your preferred destinations. You can reliably stream on-chain events to webhooks, databases, or messaging systems without manual polling or managing infrastructure.
Streams ensures data consistency, scalability, and guaranteed delivery, so your applications stay up to date with every blockchain event.
Learn how to set up Quicknode Streams and get blockchain data to your app.
Resources
Webhooks
Tracking onchain activity requires deep knowledge of the blockchain's data models and robust infrastructure. Ensuring reliability and the lowest latencies requires frequent polling or redundant websocket connections which can be very costly at scale.
Webhooks allow you to receive real-time notifications for onchain events. You can set up expressions to target specific data on the blockchain (e.g., transactions to/from a specific wallet, smart contract events, or even new blocks) to track specific onchain activity.
When your specified event occurs, Quicknode will instantly send a notification (a webhook) to a destination URL you provide, eliminating the need for constant polling.
Resources
Solana gRPC
Solana gRPC streams Solana account, slot, block, and transaction updates over a Yellowstone-compatible Geyser gRPC interface. You subscribe once and receive updates as the validator sees them, which is faster and cheaper than polling getAccountInfo in a loop or maintaining a fleet of WebSocket subscriptions.
Resources
Indexed Data
SQL Explorer
SQL Explorer provides direct SQL access to indexed blockchain data without requiring any infrastructure. You can query billions of rows of on-chain data using standard SQL syntax and receive results in seconds.
SQL Explorer supports full SQL functionality including functions, subqueries, window functions, CTEs, and aggregations. You can access it through the interactive dashboard or programmatically via the REST API.
Resources
Blockbook
Blockbook is a wallet-centric indexer for UTXO and EVM chains. Rather than scanning blocks yourself, you query an address or xpub and get balances, transaction history, and UTXOs back in one call over REST or JSON-RPC.
Resources
Metaplex DAS API
The Metaplex Digital Asset Standard (DAS) API is the query layer for Solana digital assets. It returns NFTs, compressed NFTs, fungible tokens, and MPL Core assets by owner, group, creator, or authority, including the compressed assets that standard RPC methods cannot resolve on their own.
Resources
Ordinals & Runes API
The Ordinals & Runes API exposes Bitcoin inscriptions and Runes as structured data. You can look up inscriptions, satoshi ranges, collections, Runes balances, and the UTXOs holding them over REST or JSON-RPC.
Resources
AI Agents (ERC-8004)
ERC-8004 is the onchain standard for AI agent identity and reputation. The AI Agents API turns it into a query-ready REST and JSON-RPC interface: no node syncing, no event log parsing, and no reputation formula to implement yourself.
Discover registered agents by owner address or network and retrieve a transparently computed reputation score, built from feedback scoring, sybil resistance, reliability, and validator-weighted signals. You can also list an agent's full feedback and validation history and query outstanding validator requests. The underlying data is continuously indexed from live contract events across mainnet and testnet deployments on the most widely used EVM-compatible chains, so results reflect current onchain state.
Resources
Token & NFT API
The Token & NFT API answers wallet-level questions in a single call instead of making you enumerate contracts and call balanceOf yourself. You pass an address and get back ERC-20 balances, NFT holdings with metadata, and transfer history across supported EVM networks.
Resources
Trading & DeFi
Swap API
The Swap API aggregates token swap liquidity across Solana and EVM networks behind a single integration. You request a quote, receive a route, and get back a ready-to-sign transaction, so you never have to connect to individual DEXs yourself.
One API key covers every supported provider, including Metis (Jupiter) on Solana and 0x, OpenOcean, Aerodrome, and Velodrome on EVM networks. On Solana, Metis also covers Pump.fun trading, limit orders, and WebSocket price updates.
Resources
Earn
Earn is a non-custodial USDC yield optimizer. You deposit once, and Earn allocates the balance across Morpho vaults on supported EVM networks, rebalancing and bridging automatically as rates move. Funds stay in your control throughout, and the same behavior is available through a REST API if you want to offer yield inside your own app.
Resources
Solana Validator
Quicknode runs a high-performance, public validator on the Solana network, offering a secure way to stake your SOL.
With a 0% commission fee, 100% of all staking rewards, including JITO tips (MEV rewards), are passed directly to you. By delegating your stake to the Quicknode validator, you help support the decentralization and security of the Solana network while maximizing your yield, all backed by Quicknode's industry-leading 100% uptime and reliability.

Monad Validator
Quicknode also operates a validator on Monad. You can delegate MON to it from your wallet and earn staking rewards while Quicknode handles the infrastructure, monitoring, and uptime. See the Monad staking page for current commission and reward details.
Resources
Storage
IPFS
Blockchain storage space is costly, and storing files on the blockchain network could be impractical. That is where decentralized storage protocol like IPFS comes into play. IPFS (InterPlanetary File System) is a peer-to-peer file storage system.
Files on IPFS are uploaded via IPFS nodes, and when these files are not accessed for a long time or if the node goes down, the file can be lost.
With Quicknode's IPFS pinning service, you can pin your IPFS files without worrying about losing access to your data. You can upload, store, and manage your files anytime, and they will be available anytime you want to access them without running your own IPFS node.
Since IPFS is a protocol, most browsers cannot access the files natively as they work with HTTPS protocol. So, one needs a gateway to access files on IPFS via HTTPS protocol. Quicknode offers IPFS gateways, which you can use to access files from IPFS. With Quicknode, you can create custom domains for your IPFS gateways and create private (can only access files uploaded via Quicknode IPFS pinning) or public (can access any file stored on IPFS) gateways.
Quicknode IPFS pinning can be accessed via both Quicknode dashboard and REST API.

Key-Value Store
Key-Value Store is a robust data storage solution that enables you to manage extensive lists of datapoints, such as millions of wallet addresses, and key-value sets.
It is designed for efficient storage and quick retrieval, integrating seamlessly with Quicknode Streams. This allows you to evaluate your stored lists (e.g., a list of tracked wallets) against real-time blockchain data with high efficiency.
Resources
Platform
Admin API
The Admin API allows you to programmatically manage your account and resources via a REST API. This gives you the power to perform actions that you would normally do in the User Dashboard, such as:
- Creating, managing, and deleting endpoints
- Retrieving metrics and billing information
- Managing and rotating API keys
- Configuring endpoint security features (e.g., whitelisting, JWT authentication)
Resources
Custom RPC Options
Quicknode offers custom RPC options designed for enterprise customers who require performance, isolation, and scalability beyond standard shared infrastructure. These solutions are ideal for latency-sensitive applications (e.g., trading) or operations that require a private environment to ensure consistent performance.
Resources
Toolkit
Apart from proprietary products, the Quicknode team also creates tools to help developers jump-start dApp development.
SDK
SDK is an open-source software development kit that makes it easier to interact with Quicknode product APIs, including the Admin API, Streams, Webhooks, and Key-Value Store.
You can install the SDK via:
npm i @quicknode/sdk
Resources
Multi-chain Faucet
Before deploying the dApps on a main blockchain network, we usually test them on testnets. Developing on testnet requires testnet tokens and what Multi-chain Faucet offers.
You can get testnet tokens for multiple blockchain testnet networks and bonus tokens if you're signed in to your Quicknode account or post a Tweet.
Smart Contract Explorer
Smart Contract Explorer as the name suggests helps you get valuable data from smart contracts across EVM networks.
With Smart Contract Explorer, you can access smart contracts of popular protocols, smart contract ABIs, smart contract events, deploy alerts for contract events. You can even play with smart contract read and write functions in the Smart Contract Explorer platform. Cherry on the cake is that if you want to interact with these smart contract functions in your codebase, you can get code examples in multiple languages and libraries.
EtherFlow
EtherFlow is a tool that can be used to compose EVM RPC methods in a visual manner. You can pass your HTTPS or WebSocket endpoint and call the majority of the methods from the EtherFlow dashboard.
You can even get code examples in web3.js and ethers.js.
