Arbitrum Quick Facts

Arbitrum is an L2 scaling solution for Ethereum. It is a suite of Ethereum scaling solutions that enables high-throughput, low cost smart contracts while remaining trustlessly secure. Arbitrum has security rooted in Ethereum, with any one party able to ensure correct Layer 2 results. Arbitrum is also able to run unmodified EVM contracts and unmodified Ethereum transactions. Moving contract computation and storage off of the main Ethereum chain allows for much higher throughput. Designed and engineered to minimize the L1 gas footprint of the system, Arbitrum minimizes per-transaction cost.


Note about how we calculate transaction fees on Arbitrum:

Generally, the fees_paid in our transaction response is simply the product of gas_price and gas_spent .

However for Arbitrum, the fees_paid in our transaction response is the sum of multiple L1 and L2 fees associated with the function call, transaction execution and storage.

To calculate the same fees_paid provided in our transaction response from Arbiscan , take the product of their Gas Price Bid and Gas Usage.
