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 $63+ chains supported on 1RPC. Customizable keys allow users to define their own permissions, providing greater control over features and access levels.

What is a RPC?

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.

How is my wallet protected with 1RPC?

1RPC is a lightweight RPC relay that protects your blockchain interactions by eradicating metadata exposure and leakage. When connecting your wallet like MetaMask to 1RPC, personally identifiable information is decoupled from the wallet address to preserve your data privacy.

How do I add opBNB to my wallet?

With most crypto wallets, you can easily add a new network by navigating to the Network Settings section. Copy and add the details, including the 1RPC URL, the network Chain ID and other details. MetaMask users can add the network to the wallet with just a single click on our site.
