Quick Start

Get Your Endpoint

1. Visit quicknode.com/endpoints
2. Select Solana and your network (Mainnet / Devnet)
3. Create an endpoint
4. Copy the HTTP and WSS URLs

Environment Setup

# .env file
QUICKNODE_RPC_URL=https://your-endpoint.solana-mainnet.quiknode.pro/your-token/
QUICKNODE_WSS_URL=wss://your-endpoint.solana-mainnet.quiknode.pro/your-token/
QUICKNODE_API_KEY=your_console_api_key  # Optional: for Admin API

Basic Setup with @solana/kit

import { createSolanaRpc, createSolanaRpcSubscriptions } from "@solana/kit";

const rpc = createSolanaRpc(process.env.QUICKNODE_RPC_URL!);
const rpcSubscriptions = createSolanaRpcSubscriptions(process.env.QUICKNODE_WSS_URL!);

// Make RPC calls
const slot = await rpc.getSlot().send();
const balance = await rpc.getBalance(address).send();

Authentication

Quicknode endpoints include authentication in the URL:

https://{ENDPOINT_NAME}.solana-mainnet.quiknode.pro/{TOKEN}/

Enable JWT authentication or IP allowlisting in the Quicknode dashboard for additional security.

RPC Endpoints

DAS API (Digital Asset Standard)

Comprehensive API for querying Solana digital assets — standard NFTs, compressed NFTs (cNFTs), fungible tokens, MPL Core Assets, and Token 2022 Assets. Available as a Marketplace add-on (Metaplex DAS API).

Get Assets by Owner

const response = await fetch(process.env.QUICKNODE_RPC_URL!, {
  method: "POST",
  headers: { "Content-Type": "application/json" },
  body: JSON.stringify({
    jsonrpc: "2.0",
    id: 1,
    method: "getAssetsByOwner",
    params: {
      ownerAddress: "E645TckHQnDcavVv92Etc6xSWQaq8zzPtPRGBheviRAk",
      limit: 10,
      options: { showFungible: true, showCollectionMetadata: true },
    },
  }),
});

const { result } = await response.json();
// result.total — total assets
// result.items — array of asset metadata
// result.cursor — for pagination

Search Assets

const response = await fetch(process.env.QUICKNODE_RPC_URL!, {
  method: "POST",
  headers: { "Content-Type": "application/json" },
  body: JSON.stringify({
    jsonrpc: "2.0",
    id: 1,
    method: "searchAssets",
    params: {
      ownerAddress: "E645TckHQnDcavVv92Etc6xSWQaq8zzPtPRGBheviRAk",
      tokenType: "fungible",
      limit: 50,
    },
  }),
});

Yellowstone gRPC (Solana Geyser)

High-performance Solana Geyser plugin for real-time blockchain data streaming via gRPC. Available as a Marketplace add-on.

Setup

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

// Derive gRPC URL from HTTP endpoint:
// HTTP:  https://example.solana-mainnet.quiknode.pro/TOKEN/
// gRPC:  https://example.solana-mainnet.quiknode.pro:10000
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("Transaction:", data.transaction);
  }
  if (data.account) {
    console.log("Account update:", data.account);
  }
});

// Subscribe to transactions for a specific program
stream.write({
  transactions: {
    txn_filter: {
      vote: false,
      failed: false,
      accountInclude: ["PROGRAM_PUBKEY"],
      accountExclude: [],
      accountRequired: [],
    },
  },
  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

gRPC Best Practices

• Use port 10000 for gRPC connections
• Set commitment to CONFIRMED for most use cases, FINALIZED for irreversibility
• Enable zstd compression to reduce bandwidth
• Send keepalive pings every 10 seconds to maintain connections
• Implement reconnection logic with exponential backoff
• Use narrow filters (specific accounts or programs) to minimize data volume

Priority Fee API

Estimate priority fees for optimal transaction landing.

// Get recommended priority fees
const response = await fetch(process.env.QUICKNODE_RPC_URL!, {
  method: "POST",
  headers: { "Content-Type": "application/json" },
  body: JSON.stringify({
    method: "qn_estimatePriorityFees",
    params: {
      last_n_blocks: 100,
      account: "YOUR_ACCOUNT_PUBKEY",
    },
  }),
});

Using Priority Fees in Transactions

import {
  pipe,
  createTransactionMessage,
  setTransactionMessageFeePayer,
  setTransactionMessageLifetimeUsingBlockhash,
  prependTransactionMessageInstructions,
  appendTransactionMessageInstruction,
} from "@solana/kit";
import {
  getSetComputeUnitLimitInstruction,
  getSetComputeUnitPriceInstruction,
} from "@solana-program/compute-budget";

// 1. Get fee estimate
const feeResponse = await fetch(process.env.QUICKNODE_RPC_URL!, {
  method: "POST",
  headers: { "Content-Type": "application/json" },
  body: JSON.stringify({
    method: "qn_estimatePriorityFees",
    params: { last_n_blocks: 100, account: payer.address },
  }),
});
const feeData = await feeResponse.json();
const priorityFee = feeData.result.per_compute_unit.high;

// 2. Build transaction with compute budget
const tx = pipe(
  createTransactionMessage({ version: 0 }),
  (tx) => setTransactionMessageFeePayer(payer.address, tx),
  (tx) => setTransactionMessageLifetimeUsingBlockhash(blockhash, tx),
  (tx) => prependTransactionMessageInstructions([
    getSetComputeUnitLimitInstruction({ units: 200_000 }),
    getSetComputeUnitPriceInstruction({ microLamports: BigInt(priorityFee) }),
  ], tx),
  (tx) => appendTransactionMessageInstruction(mainInstruction, tx),
);

Metis — Jupiter Swap API

Quicknode's hosted Jupiter Swap API for DEX aggregation. Available as a Marketplace add-on.

import { createJupiterApiClient } from "@jup-ag/api";

const jupiterApi = createJupiterApiClient({
  basePath: process.env.QUICKNODE_METIS_URL!,
});

// Get swap quote
const quote = await jupiterApi.quoteGet({
  inputMint: "So11111111111111111111111111111111111111112",   // SOL
  outputMint: "EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v", // USDC
  amount: 1_000_000_000, // 1 SOL
  slippageBps: 50,
});

// Get swap transaction
const swapResult = await jupiterApi.swapPost({
  swapRequest: {
    quoteResponse: quote,
    userPublicKey: "YourPubkey...",
  },
});

Streams

Real-time and historical blockchain data pipelines that filter, transform, and deliver data to 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, token transfers
Receipt	Transaction receipts	Status tracking

Setup

1. Create a stream in the Quicknode dashboard
2. Select Solana and the data type
3. Add a filter function (JavaScript)
4. Configure destination (webhook, S3, PostgreSQL, Azure)

Filter Function Example

function main(data) {
  // Filter for transactions involving a specific program
  const PROGRAM_ID = "YOUR_PROGRAM_ID";
  const hasProgram = data.transaction?.message?.accountKeys?.some(
    (key) => key === PROGRAM_ID
  );
  if (!hasProgram) return null;
  return data;
}

Streams vs Webhooks

Feature	Streams	Webhooks
Complexity	More configuration	Simple setup
Filtering	Custom JavaScript	Template-based
Destinations	Webhook, S3, Postgres, Azure, Snowflake	HTTP endpoint only
Processing	Full transformation	Limited
Use Case	Complex pipelines	Simple alerts

Webhooks

Event-driven notifications for Solana blockchain activity.

Webhook Setup

Create webhooks via the Quicknode dashboard or Admin API to receive notifications when specific on-chain events occur.

See resources/webhooks-reference.md for API examples and configuration.

IPFS Storage

Decentralized file storage via Quicknode's IPFS gateway.

// Upload file to IPFS
const formData = new FormData();
formData.append("file", fileBuffer);

const response = await fetch("https://api.quicknode.com/ipfs/rest/v1/s3/put-object", {
  method: "POST",
  headers: { "x-api-key": process.env.QUICKNODE_API_KEY! },
  body: formData,
});

const { pin } = await response.json();
// Access via: https://quicknode.quicknode-ipfs.com/ipfs/{pin.cid}

Common Use Cases

• NFT metadata storage
• Asset hosting for collections
• Decentralized content persistence

Key-Value Store

Serverless storage for lists and key-value sets, accessible from Streams filter functions via the qnLib helper library.

Stream Integration (qnLib)

// In a Streams filter function:

// List operations — manage address watchlists
await qnLib.qnAddListItem("my-watchlist", "E645TckHQnDcavVv92Etc6xSWQaq8zzPtPRGBheviRAk");
const isWatched = await qnLib.qnContainsListItems("my-watchlist", [data.from]);

// Set operations — store key-value pairs
await qnLib.qnAddSet("token-prices", { key: "SOL", value: "150.25" });
const price = await qnLib.qnGetSet("token-prices", "SOL");

List Operations

• qnLib.qnUpsertList — create or update a list
• qnLib.qnAddListItem — add item to a list
• qnLib.qnRemoveListItem — remove item from a list
• qnLib.qnContainsListItems — batch membership check
• qnLib.qnDeleteList — delete a list

Set Operations

• qnLib.qnAddSet — create a key-value set
• qnLib.qnGetSet — retrieve value by key
• qnLib.qnBulkSets — bulk create/remove sets
• qnLib.qnDeleteSet — delete a set

Quicknode SDK

Official JavaScript/TypeScript SDK for Quicknode services.

npm install @quicknode/sdk

import { Core } from "@quicknode/sdk";

const core = new Core({
  endpointUrl: process.env.QUICKNODE_RPC_URL!,
});

// Token API
const balances = await core.client.qn_getWalletTokenBalance({
  wallet: "E645TckHQnDcavVv92Etc6xSWQaq8zzPtPRGBheviRAk",
});

// NFT API
const nfts = await core.client.qn_fetchNFTs({
  wallet: "E645TckHQnDcavVv92Etc6xSWQaq8zzPtPRGBheviRAk",
  page: 1,
  perPage: 10,
});

Admin API

REST API for programmatic management of Quicknode endpoints, usage, rate limits, security, and billing.

Authentication

All Admin API requests use the x-api-key header against https://api.quicknode.com/v0/.

const QN_API_KEY = process.env.QUICKNODE_API_KEY!;

// List all endpoints
const res = await fetch("https://api.quicknode.com/v0/endpoints", {
  headers: { "x-api-key": QN_API_KEY },
});
const endpoints = await res.json();

// Get usage metrics
const usage = await fetch("https://api.quicknode.com/v0/usage/rpc", {
  headers: { "x-api-key": QN_API_KEY },
});

Quick Reference

Resource	Methods	Endpoint
Chains	GET	/v0/chains
Endpoints	GET, POST, PATCH, DELETE	/v0/endpoints
Metrics	GET	/v0/endpoints/{id}/metrics
Rate Limits	GET, POST, PUT	/v0/endpoints/{id}/rate-limits
Usage	GET	/v0/usage/rpc
Billing	GET	/v0/billing/invoices

x402 (Pay-Per-Request RPC)

Pay-per-request RPC access via USDC micropayments on Base. No API key required.

import { wrapFetch } from "@x402/fetch";
import { createWalletClient, http } from "viem";
import { privateKeyToAccount } from "viem/accounts";
import { base } from "viem/chains";

const account = privateKeyToAccount(process.env.PRIVATE_KEY as `0x${string}`);
const walletClient = createWalletClient({
  account,
  chain: base,
  transport: http(),
});

// Wrap fetch to auto-handle 402 payments
const x402Fetch = wrapFetch(fetch, walletClient);

// Use like normal fetch — payments handled automatically
const response = await x402Fetch("https://x402.quicknode.com/solana-mainnet", {
  method: "POST",
  headers: { "Content-Type": "application/json" },
  body: JSON.stringify({
    jsonrpc: "2.0",
    method: "getSlot",
    params: [],
    id: 1,
  }),
});

Multi-Chain Support

Quicknode supports 80+ blockchain networks beyond Solana:

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

Full list: quicknode.com/chains

Multi-Chain Setup

import { Core } from "@quicknode/sdk";

const chains = {
  solana: new Core({ endpointUrl: process.env.QUICKNODE_SOL_RPC! }),
  ethereum: new Core({ endpointUrl: process.env.QUICKNODE_ETH_RPC! }),
  polygon: new Core({ endpointUrl: process.env.QUICKNODE_POLYGON_RPC! }),
};

Safety Defaults

• Default to 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
• Require explicit confirmation before creating Streams, Webhooks, or IPFS uploads

Error Handling

try {
  const response = await fetch(process.env.QUICKNODE_RPC_URL!, {
    method: "POST",
    headers: { "Content-Type": "application/json" },
    body: JSON.stringify({ jsonrpc: "2.0", id: 1, method: "getSlot", params: [] }),
  });
  if (!response.ok) {
    if (response.status === 401) console.error("Invalid endpoint URL or token");
    if (response.status === 429) console.error("Rate limited — upgrade plan or reduce requests");
    if (response.status >= 500) console.error("Server error — retry with backoff");
  }
} catch (error) {
  console.error("Network error:", error);
}

Common Error Codes

Code	Meaning	Solution
401	Invalid authentication	Verify endpoint URL and token
429	Rate limited	Upgrade plan or add delays
500+	Server error	Retry with exponential backoff

Best Practices

API Key Security

• Never commit endpoint URLs or API keys to git
• Use environment variables
• Enable IP allowlisting for production
• Use JWT authentication for sensitive operations
• Rotate credentials periodically

Performance

• Use WebSocket subscriptions for real-time data
• Batch RPC requests to reduce API calls
• Cache responses when data does not change frequently
• Use Yellowstone gRPC for lowest-latency streaming
• Set appropriate commitment levels (confirmed for most, finalized for irreversibility)

Reliability

• Implement retry logic with exponential backoff
• Handle rate limits gracefully with backoff
• Use Streams for reliable event processing (automatic retries)
• Monitor endpoint health via Admin API metrics
