How to Integrate Berachain RPC into Web3 Wallets and DeFi Projects
If you’ve been keeping an eye on the Web3 space, chances are you’ve heard of Berachain. It’s an EVM-compatible blockchain built on a unique Proof-of-Liquidity model, making it an interesting playground for DeFi developers and wallet builders alike.
But here’s the thing: no matter how powerful a blockchain is, you can’t do much with it until you can actually talk to it. That’s where RPC (Remote Procedure Call) comes in.
In this post, let’s walk through why RPC is so important, how wallets and DeFi projects can plug into Berachain, and check out a real request example to see it in action.
Why RPC Matters in the First Place
RPC is basically the language your app uses when asking the blockchain for something.
When a wallet checks your BERA balance → that’s an RPC call.
When a DEX pulls liquidity pool data → another RPC call.
When you send a transaction → yep, also RPC.
For Berachain, this means your app needs a Berachain RPC URL to connect. If you’re working with the live chain, that would be the Berachain Mainnet RPC URL. And unless you want to run your own node (which is a headache), you’ll probably use a Berachain RPC provider like NOWNodes to get one.
Adding Berachain RPC to Wallets
Web3 wallets (think MetaMask, Rabby, TrustWallet) are flexible — you can point them to different blockchains by adding custom RPC endpoints.
Once you plug in a Berachain RPC URL, the wallet can:
Show balances in BERA and ERC-20 tokens on Berachain.
Sign and broadcast transactions directly to the chain.
Connect users to Berachain-based dApps with no friction.
It’s a small change in wallet settings, but it makes a huge difference: suddenly the wallet speaks the language of Berachain.
How DeFi Apps Use Berachain RPC
DeFi projects are even more dependent on RPC than wallets. For a DEX, lending protocol, or staking dashboard, RPC isn’t just a connector — it’s the core pipeline for all the data.
With a stable Berachain RPC provider, you can:
Fetch pool balances and reserves in real time.
Track user portfolios and yield data.
Call smart contracts for swaps, deposits, or rewards.
Push transactions on-chain and confirm them quickly.
No RPC, no DeFi — it’s as simple as that.
Let’s Try a Real Example
Here’s a minimal RPC call using Berachain’s endpoint from NOWNodes. This one just asks for the current block number:
{"jsonrpc": "2.0", "method": "eth_blockNumber", "id": 1, "params": []}
And the blockchain replies with something like:
{
"jsonrpc": "2.0",
"id": 1,
"result": "0x12d90c9"
}
That result is the latest block number in hexadecimal. Pretty straightforward — and you can swap out eth_blockNumber for methods like eth_getBalance or eth_call to build more complex features.
This is exactly how wallets display balances and how DeFi apps query pool data: everything flows through an RPC call like this.
Why Choosing the Right RPC Provider Matters
Technically, you could spin up your own node and expose an RPC endpoint. But most teams skip that — syncing, maintaining, and scaling a node is expensive and distracting.
A Berachain RPC provider solves this by giving you a ready-to-use endpoint with high uptime and scalability. That means:
Users won’t see “stuck” balances in their wallets.
DeFi apps won’t fail when processing a swap.
You don’t waste time firefighting infrastructure.
In short: reliability at the RPC layer translates directly into better UX for your users.
Wrapping Up
Integrating Berachain RPC into wallets and DeFi projects is both simple and essential.
Wallets need it to show balances and send transactions.
DeFi projects need it to fetch pool data, query contracts, and process trades.
With a Berachain Mainnet RPC URL, you’re connected to the heartbeat of the network and ready to build.
If you’re starting out, grab a Berachain RPC endpoint from a provider like NOWNodes — it’ll save you hours of setup and let you focus on shipping features, not running nodes.
