The BNB Chain has emerged as one of the most dynamic and developer-friendly blockchains in the Web3 ecosystem. Known for its high throughput, low transaction fees, and full Ethereum Virtual Machine (EVM) compatibility, it’s no surprise that developers are flocking to build decentralized applications (dApps), DeFi protocols, and blockchain-based games on this scalable network.
At the heart of seamless development lies robust infrastructure — and that’s where reliable Remote Procedure Call (RPC) services come in. Whether you're launching a new dApp or scaling an existing project, having fast, stable, and decentralized access to the BNB Chain is essential.
Why Build on the BNB Chain?
The BNB Chain, originally known as Binance Smart Chain (BSC), operates parallel to the Binance Chain and introduces smart contract functionality. This makes it ideal for building complex decentralized applications while benefiting from Binance’s vast ecosystem and user base.
Developers choose BNB Chain for several compelling reasons:
- EVM Compatibility: Seamlessly deploy Ethereum-based dApps with minimal code changes.
- Low Gas Fees: Significantly reduced transaction costs compared to legacy chains like Ethereum.
- High Speed & Scalability: Capable of processing transactions quickly, supporting high-volume applications like gaming and DeFi.
- Interoperability: Easily integrates with cross-chain tools and bridges, enabling multichain functionality.
- Thriving Ecosystem: Backed by a strong community, grants programs, and infrastructure support.
With these advantages, the BNB Chain has become a top choice for Web3 innovators looking to scale without sacrificing performance.
Understanding RPCs in Web3 Development
Remote Procedure Calls (RPCs) are foundational to blockchain development. In simple terms, an RPC allows your application or wallet to communicate with a blockchain network by sending requests and receiving data — all without needing to run your own node.
For example, when a user checks their token balance or initiates a transaction through a Web3 wallet, the app uses an RPC endpoint to query the blockchain for real-time data.
Without RPCs, developers would need to maintain their own full nodes — a resource-intensive process involving server management, constant syncing, and high availability requirements.
Instead, node infrastructure providers offer public and premium RPC endpoints that make connecting to blockchains like BNB Chain fast, easy, and cost-effective.
What Is the BNB Chain RPC?
The BNB Chain RPC acts as a bridge between your application and the BNB Chain network. It enables developers to send queries — such as retrieving wallet balances, checking transaction status, or broadcasting new transactions — directly to the blockchain.
Ankr provides decentralized, geo-distributed BNB Chain RPC endpoints that ensure high availability, low latency, and resistance to outages. These endpoints are maintained by a global network of independent node operators, enhancing security and reliability.
There are two main types of access:
- Public RPC: Free to use, no registration required. Ideal for testing and light development.
- Premium RPC: Offers higher rate limits, dedicated support, enhanced uptime, and advanced features — perfect for production-grade dApps.
Using Ankr’s BNB Chain RPC, developers can integrate blockchain connectivity into their apps with just a few lines of code.
How to Make Your First RPC Call to BNB Chain
Getting started is simple. You can use Ankr’s public endpoint directly:
https://rpc.ankr.com/bscThis URL can be plugged into your wallet, development framework (like Hardhat or Web3.js), or command-line interface to begin interacting with the BNB Chain.
To retrieve block data using curl:
curl -X POST https://rpc.ankr.com/bsc \
-H "Content-Type: application/json" \
-d '{"jsonrpc":"2.0","method":"eth_blockNumber","params":[],"id":1}'This returns the latest block number — your first successful interaction with the chain.
For more advanced use cases, explore Ankr’s documentation on EVM JSON-RPC methods.
Enhancing Development With APIs
While RPCs handle basic blockchain communication, Application Programming Interfaces (APIs) unlock deeper functionality. APIs allow two-way interactions — reading and writing data — making them essential for dApps that require real-time updates, NFT management, or complex smart contract operations.
Ankr’s Developer APIs streamline development with powerful tools designed for efficiency and scalability.
Key Features of Ankr’s Developer APIs
1. Data API – Query Multi-Chain Data Instantly
Instead of making multiple RPC calls across blocks and chains, developers can fetch large datasets in a single request. This reduces latency and simplifies backend logic, especially for analytics platforms and DeFi dashboards.
2. NFT API – Simplify Cross-Chain NFT Operations
Query NFT ownership, metadata, transaction history, and collection details across all supported EVM chains simultaneously. Whether you’re building an NFT marketplace or portfolio tracker, this API eliminates the need for manual indexing.
3. Decentralized Data Access
Unlike centralized NFT services that pose censorship risks, Ankr pulls data directly from blockchain nodes. This ensures transparency, reliability, and alignment with Web3’s decentralized ethos.
These APIs integrate seamlessly with Ankr’s RPC infrastructure, offering a unified platform for multi-chain development.
Building on BAS: BNB Chain Application Sidechains
As demand grows for scalable applications, BNB Chain Application Sidechains (BAS) offer a next-generation solution. BAS enables developers to launch dedicated sidechains tailored to their specific dApp — following a “one app, one chain” model.
Why Use BAS?
- Ultra-Low or Zero Fees: Improve user experience by eliminating gas costs for end users.
- Custom Consensus & Execution: Choose your own validator set and execution environment.
- Scalability: Avoid congestion by isolating your app’s traffic from the mainnet.
- Seamless Integration: Fully interoperable with the BNB Chain hub via trustless bridges.
BAS supports various implementations including Proof-of-Stake (PoS) sidechains and ZK Rollups. The framework is permissionless and flexible — developers can start with Go-Ethereum or build custom solutions using Wasm, sharding, or L2 technologies.
Ankr supports BAS development by providing decentralized node infrastructure so teams don’t need to manage their own validators.

Explore AnkrScan: A Unified Multichain Block Explorer
Navigating multiple blockchains often means juggling different explorers — Etherscan for Ethereum, BscScan for BNB Chain, etc. AnkrScan solves this fragmentation.
AnkrScan is a multichain block explorer supporting 11+ networks including BNB Chain, Ethereum, Polygon, Arbitrum, and more — with continuous expansion planned.
Use AnkrScan to:
- View wallet balances across chains
- Track cross-chain transactions
- Explore NFT holdings and transfer history
- Monitor smart contract interactions
It’s an essential tool for developers, auditors, and users building or navigating the multichain future.
