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,
    },
  }),
});

Get Asset Proof (Compressed NFTs)

const response = await fetch(process.env.QUICKNODE_RPC_URL!, {

    jsonrpc: "2.0",
    id: 1,
    method: "getAssetProof",
    params: { id: "compressed_nft_id" },
  }),
});

DAS Method Reference

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](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.
