How to Use the QuickNode Multichain Endpoint

·

In today’s rapidly evolving blockchain ecosystem, developers are increasingly building decentralized applications (dApps) that span multiple networks. Managing separate endpoints for each blockchain can become cumbersome and inefficient. Enter QuickNode's Multichain Endpoint — a powerful solution that streamlines cross-chain development by allowing you to interact with multiple blockchains using a single, unified endpoint.

This guide walks you through everything you need to know about enabling, configuring, and testing a Multichain endpoint, ensuring your dApp development process is both efficient and secure.

What Is the QuickNode Multichain Feature?

QuickNode’s Multichain functionality enables developers to access multiple blockchain networks — including Ethereum, Solana, Binance Smart Chain, Avalanche, Base, and more — through one centralized endpoint. Whether you're building cross-chain DeFi protocols, NFT marketplaces, or Web3 gaming platforms, this feature simplifies infrastructure management without sacrificing performance or security.

The best part? The Multichain feature is available on both free and paid plans, making it accessible to startups, indie developers, and enterprise teams alike.

Key Benefits of Using a Multichain Endpoint

Understanding the QuickNode Endpoint URL Structure

Each blockchain network uses a specific URL format based on subdomains. This standardized structure ensures consistency while supporting unique configurations where necessary.

General Endpoint Format

https://{YOUR_ENDPOINT_NAME}.{NETWORK_NAME}.quiknode.pro/{YOUR_TOKEN_ID}

For most chains, {NETWORK_NAME} follows the pattern chainName-networkName. However, exceptions exist — such as Avalanche, which requires an additional path segment.

Example URLs by Blockchain

🔍 Always verify the exact URL format in your QuickNode dashboard, as some networks have special routing requirements.

Step-by-Step: Enable Multichain on Your Endpoint

Follow these steps to activate and configure your Multichain endpoint.

Step 1: Log In to Your QuickNode Account

Visit QuickNode’s website and sign in. If you don’t have an account, registration is free and only takes a minute.

Once logged in, navigate to the Endpoints section from the dashboard.

Step 2: Create or Select an Existing Endpoint

If you’re starting fresh:

If you already have an endpoint, select it from the list.

Step 3: Enable Multichain Mode

With your endpoint selected:

QuickNode will automatically generate the correct URL for each selected chain using your shared endpoint name and token.

Step 4: Centralize Security Settings

Now that multiple chains are linked, go to the Security tab to manage unified controls:

This centralized approach reduces administrative overhead and improves security posture.

Frequently Asked Questions

Q: Is the Multichain feature available on free accounts?
A: Yes! All QuickNode users — including those on free plans — can enable Multichain support at no extra cost.

Q: Can I use different rate limits for different chains?
A: No. When Multichain is enabled, rate limits are applied uniformly across all connected networks. For granular control, consider using separate endpoints.

Q: Which blockchains are supported?
A: QuickNode supports major EVM and non-EVM chains including Ethereum, BSC, Polygon, Avalanche, Arbitrum, Optimism, Base, Solana, Bitcoin, and more. Check the dashboard for real-time availability.

Q: Do I need separate API keys for each chain?
A: No. One token secures access to all enabled chains under the same endpoint.

Q: How are logs handled across chains?
A: Logs are segregated by network but accessible from a single view in your dashboard, enabling streamlined debugging across chains.

Q: What happens if one chain goes down?
A: Other chains remain unaffected. Each network operates independently behind the shared endpoint structure.

Testing Your Multichain Setup

To confirm your configuration works correctly, run parallel RPC calls across two different chains using a simple bash script.

Multichain Test Script (Bash)

Create a file named multichain_test.sh:

#!/bin/bash

get_timestamp(){
    date +"%Y-%m-%d %H:%M:%S.%6N"
}

make_rpc_call(){
    local endpoint=$1
    local start_timestamp=$(get_timestamp)
    echo "[START] $start_timestamp - Making call to $endpoint"

    local start_time=$(date +%s.%N)
    response=$(curl -s -X POST \
        -H "Content-Type: application/json" \
        --data '{
          "jsonrpc":"2.0",
          "method":"eth_blockNumber",
          "params":[],
          "id":1
        }' "$endpoint")
    local end_time=$(date +%s.%N)
    local duration=$(echo "$end_time - $start_time" | bc)

    local end_timestamp=$(get_timestamp)
    echo "[END] $end_timestamp - Completed call to $endpoint"

    block_hex=$(echo $response | grep -o '"result":"[^"]*"' | cut -d'"' -f4)
    if [ ! -z "$block_hex" ]; then
        block_dec=$((16#${block_hex#0x}))
        echo "Endpoint: $endpoint"
        echo "Block Number: $block_dec"
        printf "Response Time: %.3f seconds\n" $duration
    else
        echo "Error for endpoint $endpoint: $response"
    fi
    echo "-------------------"
}

echo "Script started at $(get_timestamp)"
echo "-------------------"

ENDPOINT1="https://your-endpoint.ethereum.quiknode.pro/your-token/"     # Replace with actual Ethereum URL
ENDPOINT2="https://your-endpoint.base-mainnet.quiknode.pro/your-token/" # Replace with actual Base URL

make_rpc_call "$ENDPOINT1" &
make_rpc_call "$ENDPOINT2" &

wait

echo "-------------------"
echo "All RPC calls completed at $(get_timestamp)"

How to Run the Script

  1. Save the file

  2. Make it executable:

    chmod +x multichain_test.sh

  3. Execute:

    ./multichain_test.sh

You should see output showing block numbers and response times from both chains — proof that your single endpoint successfully communicates with multiple networks.

Final Thoughts

QuickNode’s Multichain endpoint is a game-changer for modern blockchain development. By consolidating access to multiple networks under one secure, manageable interface, it reduces operational friction and accelerates time-to-market for cross-chain applications.

Whether you’re integrating Layer 2 solutions like Base or syncing data across Solana and Ethereum, this tool brings simplicity and scalability to your stack.

And remember — robust infrastructure is just one part of building successful Web3 projects. Pairing reliable node services with strategic planning and efficient workflows makes all the difference.
