About Arbitrum & Arbitrum Nova

Arbitrum is a technology suite designed to scale Ethereum. You can use Arbitrum chains to do all things you do on Ethereum — use Web3 apps, deploy smart contracts, etc., but your transactions will be cheaper and faster. Arbitrum’s flagship product — Arbitrum Rollup — is an Optimistic rollup protocol that inherits Ethereum-level security.

Arbitrum Nova is a layer 2 rollup solution that uses Arbitrum Nitro and AnyTrust technology to enable ultra-low transaction fees paired with high throughput and security. Nova enables developers to build a wide variety of applications, such as game development, decentralized social, NFTs and DeFi. Reddit recently launched a beta version of their community points system, built using Arbitrum Nova, and expected to onboard a mass of new users to web3.

How is Lava supporting Arbitrum?

Developers building on Arbitrum can use Lava’s RPC endpoints to query data from Arbitrum One & Nova without running their own node or relying on a single provider.

Lava’s Arbitrum endpoints support JSON-RPC and Websocket Subscriptions.

Calling developers! We have limited early spots for applications to use our network. Apply here.

Soon we’ll be releasing our Decentralized Access SDK, that will also support Arbitrum One & Nova. The SDK is a TypeScript implementation of Lava’s Protocol, that enables developers to easily plug their app into trustless access to data from any blockchain.

Decentralized RPC means reliable, secure and open-source support for any chain or API

By decentralizing RPC, Lava offers many benefits for developers:

• Decentralized redundancy for high uptime - By being connected to multiple leading RPC providers, apps benefit from 99.99% uptime. The protocol also rewards providers according to their latency, freshness, and availability.
• Open-Source - Lava is open-source and transparent, shortening the procurement process for apps looking to integrate. Anyone can also contribute to the protocol and the appchain, so developers can verify that the network is secure and reliable.
• Private relays -  Relay requests are routed per epoch to a random and constantly shuffled list of providers, so any user RPC queries going through the network cannot be profiled.
• Maximum Scalability - Lava incentivizes network redundancy and runs on a highly scalable appchain, so your app can handle high periods of traffic.
• Consensus-Based Data Integrity - Data accuracy, consistency and freshness are preserved by a consensus mechanism which detects and resolves conflicts. Poor service or attempts to manipulate data are caught and disincentivized, with providers staking and signing responses so that they can held accountable.
• Any Chain, Any API - Change your configuration to access any chain and any API served by the network.
