Quicknode Blockchain Infrastructure

Intake Questions

• Which chain and network should Quicknode target?
• Is this read-only or should I create infrastructure (streams, webhooks, IPFS writes)?
• Does this require real-time streaming (Solana gRPC/Blazar WSS/HyperCore gRPC) or standard RPC?
• What endpoint or API key should I use (default: QUICKNODE_RPC_URL, optional QUICKNODE_WSS_URL / QUICKNODE_API_KEY)?
• If no API key exists, does the agent want pay-per-request access (x402, MPP) or a wallet-paid Quicknode account via Agent Subscriptions?
• Any constraints (latency, regions, throughput, destinations)?

Safety Defaults

• Default to testnet/devnet when a network is not specified.
• Prefer read-only operations and dry runs before creating resources.
• Never ask for or accept private keys or secret keys.

Confirm Before Write

• Require explicit confirmation before creating or modifying Streams, Webhooks, or IPFS uploads.
• Require explicit confirmation before creating an Agent Subscription, topping up credits, or any action that spends real funds via x402 or MPP.
• If confirmation is missing, return the exact API payload for review.

Core RPC API

Quicknode provides low-latency RPC endpoints for 80+ blockchain networks.

qn rpc call (CLI) and qn.rpc.call (SDK) reach any supported network via Tooling Access — a single multichain, read-only endpoint Quicknode provisions automatically with short-lived JWTs. No endpoint setup required. See references/cli-reference.md / references/sdk-reference.md. Use a dedicated endpoint below for a fixed URL, non-read-only methods, or dedicated throughput.

Endpoint Setup

// EVM chains (ethers.js)
import { JsonRpcProvider } from 'ethers';
const provider = new JsonRpcProvider(process.env.QUICKNODE_RPC_URL!);

// EVM chains (viem)
import { createPublicClient, http } from 'viem';
import { mainnet } from 'viem/chains';
const client = createPublicClient({
  chain: mainnet,
  transport: http(process.env.QUICKNODE_RPC_URL!),
});

// Solana
import { createSolanaRpc } from '@solana/kit';
const rpc = createSolanaRpc(process.env.QUICKNODE_RPC_URL!);

Authentication

Quicknode endpoints include authentication in the URL:

https://{ENDPOINT_NAME}.{NETWORK}.quiknode.pro/{API_KEY}/

For additional security, enable JWT authentication or IP allowlisting in the Quicknode dashboard.

Supported Networks

Category	Networks
EVM	Ethereum, Polygon, Arbitrum, Optimism, Base, BSC, Avalanche, Fantom, zkSync, Scroll, Linea, Hyperliquid EVM (HyperEVM)
Non-EVM	Solana, Bitcoin, NEAR, Stacks, Cosmos, Sei, Aptos, Sui, TON, Hyperliquid (HyperCore)

Not exhaustive. Full list: https://www.quicknode.com/chains

Rate Limits & Plans

As of 2026-02-02. Verify current limits in Quicknode docs before sizing a production system.

Plan	Requests/sec	Credits/month
Free Trial	15	10M
Build	50	80M
Accelerate	125	450M
Scale	250	950M
Business	500	2B

See references/rpc-reference.md for complete RPC documentation including method tables for EVM, Solana, and Bitcoin chains, WebSocket patterns, and batch request examples.

IPFS

Decentralized file storage with Quicknode's IPFS gateway.

See references/ipfs-reference.md for upload examples, metadata examples, and complete IPFS documentation.

Dedicated Clusters

Dedicated private node clusters for teams requiring deterministic throughput, regional pinning, or compliance isolation. Agents typically do not provision Dedicated Clusters directly — this is an infrastructure decision made by the account owner.

Streams

Real-time & historical blockchain data pipelines that filter, transform, and deliver data to your destinations.

Stream Types

Type	Data	Use Case
Block	Full block data	Block explorers, analytics
Transaction	Transaction details	Tx monitoring, indexing
Logs	Contract events	DeFi tracking, NFT sales, token transfers
Receipt	Transaction receipts	Gas analysis, status tracking

Quick Setup

1. Create stream in Quicknode dashboard
2. Select network and data type
3. Add filter function (JavaScript)
4. Configure destination (webhook, S3, database)

See references/streams-reference.md for filter examples and full Streams documentation.

Streams Backfills

On-demand historical data delivery into an existing Stream. Use Backfills to recover gaps, seed a new data store with history, or re-index a range of blocks without rebuilding your pipeline.

Docs: https://www.quicknode.com/docs/streams/backfilling

When to Use

• A Stream destination was down and you need to replay missed blocks.
• You're launching a new Stream and need historical data from block N to the current head.
• You want to re-process a range of blocks after updating a filter function.

What to Provide

When asking an agent to trigger a Backfill, provide:

• Stream ID (from the Quicknode dashboard or Admin API)
• Start block number
• End block number (or latest)
• Destination confirmation (Backfills deliver to the Stream's existing destination)

See references/streams-backfills-reference.md for dataset selection, range planning, batching, compression, cost guidance, and automation notes.

Webhooks

Event-driven notifications for blockchain activity.

Webhooks vs Streams

Feature	Webhooks	Streams
Setup	Simple	More configuration
Filtering	Address/event-based	Custom JavaScript
Destinations	HTTP endpoint only	Webhook, S3, Postgres, Azure
Processing	Basic	Full transformation
Use Case	Simple alerts	Complex pipelines

See references/webhooks-reference.md for API examples and full Webhooks documentation.

Solana gRPC (formerly Yellowstone gRPC)

High-performance Solana Geyser plugin for real-time blockchain data streaming via gRPC. Included on Scale and Business plans; available as an add-on on Build and Accelerate plans.

Quick Setup

import Client, { CommitmentLevel } from "@triton-one/yellowstone-grpc";

// Derive from HTTP URL: https://example.solana-mainnet.quiknode.pro/TOKEN/
const client = new Client(
  "https://example.solana-mainnet.quiknode.pro:10000",
  "TOKEN",
  {}
);

const stream = await client.subscribe();
stream.on("data", (data) => {
  if (data.transaction) console.log("Tx:", data.transaction);
});

stream.write({

    },
  },
  accounts: {},
  slots: {},
  blocks: {},
  blocksMeta: {},
  transactionsStatus: {},
  entry: {},
  accountsDataSlice: [],
  commitment: CommitmentLevel.CONFIRMED,
});

Filter Types

Filter	Description
accounts	Account data changes by pubkey, owner, or data pattern
transactions	Transaction events with vote/failure/account filters
transactionsStatus	Lightweight transaction status updates
slots	Slot progression and status changes
blocks	Full block data with optional tx/account inclusion
blocksMeta	Block metadata without full contents
entry	PoH entry updates

See references/solana-grpc-reference.md for complete Solana gRPC documentation.

Blazar WSS

Quicknode-built Solana WebSocket engine. Every standard Solana subscription method (blockSubscribe, accountSubscribe, transactionSubscribe, logsSubscribe, and more) rebuilt for reliability and speed. Included free on all plans — no add-on required. Uses the same WSS endpoint URL (QUICKNODE_WSS_URL) as standard Solana RPC.

Docs: https://www.quicknode.com/docs/solana

Quick Setup

const ws = new WebSocket(process.env.QUICKNODE_WSS_URL!);

ws.on('open', () => {
  ws.send(JSON.stringify({
    jsonrpc: '2.0',
    id: 1,
    method: 'blockSubscribe',
    params: ['all', { commitment: 'confirmed', encoding: 'jsonParsed' }]
  }));
});

ws.on('message', (raw) => {
  const msg = JSON.parse(raw.toString());
  if (msg.params?.result?.value?.block) {
    console.log('New block slot:', msg.params.result.context.slot);
  }
});

Supported Subscription Methods

blockSubscribe, accountSubscribe, logsSubscribe, programSubscribe, signatureSubscribe, slotSubscribe, slotsUpdatesSubscribe, transactionSubscribe, voteSubscribe

Agent Identity (ERC-8004)

On-chain agent identity and reputation discovery based on the ERC-8004 standard. erc-8004.quicknode.com indexes registrations, feedback, validations, and reputation across supported EVM networks.

API Base: https://erc-8004.quicknode.com REST prefix: /v1

See references/agent-identity-reference.md for verified endpoints, x402 behavior, rate limits, and on-chain registration guidance.

Blockbook

Wallet-centric blockchain data via the Blockbook JSON-RPC add-on. Provides address balances, UTXO sets, and transaction history across supported chains — particularly useful for UTXO-based chains like Bitcoin where standard RPC methods lack wallet-level indexing.

Supported Chains

Bitcoin (BTC), Ethereum (ETH), Bitcoin Cash (BCH), Dogecoin (DOGE), Litecoin (LTC), Zcash (ZEC) — each as its own add-on on your endpoint.

When to Use

• Get the full balance and transaction history for a Bitcoin or UTXO-chain address.
• Fetch UTXOs to construct a transaction.
• Look up confirmed/unconfirmed balance for an address without running a personal indexer.

See references/blockbook-reference.md for methods and examples.
