# Offchain Labs (Arbitrum)

Offchain Labs is the team behind Arbitrum, a suite of Ethereum Layer 2 scaling technologies (Arbitrum One and Arbitrum Nova) built on the Nitro tech stack and the AnyTrust and Rollup protocols. Rather than a traditional REST API, Arbitrum exposes an Ethereum-compatible JSON-RPC interface plus Arbitrum-specific precompiles and the NodeInterface, and ships first-party developer tooling: the TypeScript Arbitrum SDK for bridging and cross-chain messaging, the Orbit SDK for launching custom Arbitrum chains, and the Stylus SDK (Rust/Wasm) with the cargo-stylus CLI for writing EVM-compatible smart contracts. This profile was seeded as a pantera-capital portfolio lead and enriched from Arbitrum's public developer surface.
