As blockchain technology advances, Layer-2 scaling solutions are gaining significant traction. Base is designed to offer a scalable, cost-efficient alternative to Ethereum while maintaining full EVM compatibility. With fast finality, reduced fees, and access to Ethereum tooling, Base has quickly become an attractive option for decentralized application developers and power users. To interact with Base through a non-custodial wallet or application, one must configure the network manually by specifying its connection parameters. This guide details how to integrate Base Mainnet using NOWNodes as a RPC provider.
Why Connect to Base Mainnet?
Base is designed to improve transaction throughput and reduce costs without compromising security. Therefore, it leverages Ethereum as its settlement layer and inherits its decentralization guarantees. Additionally, Base supports the full Ethereum Virtual Machine (EVM), allowing seamless contract migration from Ethereum or other compatible chains.
Key reasons to connect to Base include:
- Low transaction fees suitable for consumer-facing applications
- Full EVM compatibility and Ethereum tooling support
- Backed by Coinbase with direct integration paths for onboarding users
- Access to a growing dApp ecosystem
For these reasons, integrating Base into a wallet or dApp enables access to a high-performance Layer-2 network with minimal development overhead.
Using RPC Infrastructure via NOWNodes
In order to send transactions, query data, or interact with smart contracts on Base, a wallet or application must connect to a full node via an RPC endpoint.
Running a Base node locally requires substantial hardware, bandwidth, and operational overhead. As an alternative, NOWNodes offers shared and dedicated Base RPC access through a scalable API infrastructure. This allows any client to interface with the Base Mainnet using simple HTTP requests, without the need to operate a node.
Step 1: Obtain a Base RPC Endpoint
To begin, create an account at nownodes.io. After registration, you will be issued an API key that grants access to Base and over 110 other blockchain networks.
The Base RPC endpoint will have the following format:
https://base.nownodes.io/YOUR_API_KEY
Replace YOUR_API_KEY with your actual key.
This endpoint exposes a standard Ethereum-compatible JSON-RPC interface. Any EVM wallet, Web3 provider, or backend service that supports manual RPC configuration can use it.
Step 2: Base Mainnet Configuration Parameters
To configure your wallet or Web3 client to communicate with Base via NOWNodes, use the following network parameters:
| Parameter | Value |
|---|---|
| Network Name | Base Mainnet |
| New RPC URL | https://base.nownodes.io/YOUR_API_KEY |
| Block Explorer | https://blockexplorers.nownodes.io/base-coin |
Step 3: Test RPC Functionality
You can test that your configuration is working by making a simple JSON-RPC call using curl or any HTTP client:
For example, you can use net_listening method:
Example body (raw)
{
"id": 1,
"jsonrpc": "2.0",
"method": "net_listening"
}
Example response: 200
{
"jsonrpc": "2.0",
"id": 1,
"result": true
}
Step 4: Using Base in Your Application or Wallet
Once the Base network is added using the RPC parameters, your wallet or application will be able to:
- Send and receive transactions on Base
- Deploy or interact with smart contracts
- Monitor account balances and gas usage
This configuration is especially useful for developers building Web3 frontends or command-line tools that require direct access to the Base network via RPC.
In other words, this demonstrates how easily Base access can be integrated into an application stack using NOWNodes.
Benefits of Using NOWNodes
- Scalable infrastructure: Shared and dedicated nodes available based on project needs
- High availability: SLA-backed performance with >99.95% uptime
- Multi-chain support: Easily integrate Base alongside other networks
- No setup required: Instant access with only an API key
Whether you’re developing a dApp, integrating Base into an existing Web3 wallet, or conducting analytics on-chain, NOWNodes provides a robust and ready-to-use solution.
Conclusion
To sum up, Base is a powerful Layer-2 network that offers scalability, security, and developer convenience. By leveraging NOWNodes’ RPC infrastructure, wallets and applications can integrate Base quickly without managing their own nodes.
This guide has provided the full set of parameters and procedures necessary to establish a secure and functional connection to the Base Mainnet via a remote RPC endpoint. With this setup in place, developers and users are well-positioned to explore the growing Base ecosystem.
For production-level deployments, it is recommended to monitor performance and consider transitioning to dedicated RPC nodes to ensure stability and throughput.
