Arbitrum RPC
What is Arbitrum?
Arbitrum is a Layer 2 scaling solution for Ethereum that uses optimistic rollup technology to reduce transaction costs and increase throughput while maintaining Ethereum's security. Built by Offchain Labs, Arbitrum processes transactions off-chain and submits compressed batches to Ethereum mainnet, achieving up to 90% lower gas fees and faster confirmation times.
Arbitrum operates using an optimistic execution model. It assumes transactions are valid by default but includes a 7-day challenge period where validators can dispute fraudulent transactions through an interactive fraud-proof system. This design allows Arbitrum to inherit Ethereum's security guarantees while providing a fully EVM-compatible environment where existing Solidity smart contracts and dApps can deploy without modification.
The network uses ArbOS, a custom operating system that manages the execution environment and handles cross-chain messaging through its retryable tickets system, enabling communication between L1 and L2.
Interacting with Arbitrum
The Arbitrum JSON-RPC API extends the standard Ethereum JSON-RPC interface with Layer 2-specific functionality. Since Arbitrum maintains byte-level EVM compatibility, developers can use familiar tools like Ethers.js and Foundry without modification.
Grâce à cette API, vous pouvez :
- Execute all standard Ethereum JSON-RPC methods (eth_call, eth_sendTransaction, etc.)
- Access Arbitrum-specific methods for L2 operations (arbtrace_block, arbtrace_replayTransaction)
- Subscribe to real-time events via WebSocket connections
Vous pouvez accéder à l'API de la manière suivante :
- Running a local Arbitrum node (Nitro client)
- Using a hosted provider such as a Quicknode Arbitrum endpoint, which provides instant access to both Arbitrum One and Arbitrum Nova networks with built-in reliability and archive data support
