Optimism

Optimism RPC Endpoint

OP Mainnet is a Layer 2 Optimistic Rollup network designed to utilize the strong security guarantees of Ethereum while reducing its cost and latency.

About the Network

Optimism pioneered the OP Stack, an open-source framework powering an ecosystem of Layer 2 chains called the Superchain. The Optimism RPC allows wallets and applications to connect to the Optimism blockchain. By using the EVM-compatible Optimism RPC endpoint from 1RPC, users get private, verifiable access to the network without exposing wallet metadata or IP addresses to public RPC providers.

How to Add Optimism RPC

Add Optimism 1RPC to your wallet to use our free Optimism RPC endpoint. Follow the steps below to add the Optimism RPC endpoint manually to any Web3 wallet:

1

Check that your wallet has RPC settings and configurability

2

Navigate to add a new network

3

Paste the network details into the relevant fields

Network Name:1RPC Optimism
RPC URL:https://1rpc.io/op
Chain ID:10
Symbol:ETH
4

To add Optimism to MetaMask instantly, click on the orange button.

One-click Setup

You can also add Optimism to MetaMask automatically without entering details manually.

Privacy-protected Optimism 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.
