About the Network

opBNB extends BNB Chain's high throughput with a Layer 2 solution built on Optimism's OP Stack, creating one of the most cost-effective environments available. The opBNB RPC allows wallets and applications to connect to the opBNB blockchain. By using the EVM-compatible opBNB RPC endpoint from 1RPC, users get private, verifiable access to the network without exposing wallet metadata or IP addresses to public RPC providers.

Privacy-protected opBNB RPC endpoint

Fully attested onchain RPC relay with privacy guarantees, not assumptions.

Verifiable trust

1RPC is the first and only Web3 RPC relay with infrastructure that is fully attested onchain. Anyone can verify its integrity by assessing the relay's hardware and software components.

Phishing protection

Transaction sanitizers are anti-phishing toggles that defend against phishing attacks to prevent loss of user funds. These rules can be added and edited at any time on the 1RPC dashboard.

Zero-tracking privacy

What's private stays private. Burn after relaying wipes all metadata after request is done. True zero-tracking means we don't (and are unable to) store or collect your personal data.

Custom API access

Generate a unique API key that spins up RPC endpoints across 64+ chains supported on 1RPC. Customizable keys allow users to define their own permissions, providing greater control over features and access levels.

RPC stands for Remote Procedure Call enables interactions within a decentralized network. There are 2 components: an RPC node, which allows applications, including crypto wallets, to connect with the blockchain, and the RPC endpoint, which is a URL that acts as the gateway for accessing the functionalities of a blockchain through an RPC.
