Introduction to the Arbitrum Testnet

The full name of the Arbitrum testnet is Arbitrum Sepolia Testnet, a test chain developed by the Arbitrum team based on the Sepolia network. Before launching the Arbitrum mainnet, multiple testnets were created, such as Kovan and Rinkeby. However, with Ethereum discontinuing some of these testnets, the most widely used ones now are the Arbitrum Sepolia Testnet and Arbitrum Goerli Testnet.

The Arbitrum Sepolia Testnet also uses ETH as its currency.

Why Use the Arbitrum Testnet?

Arbitrum operates differently from Layer 1 blockchains like Ethereum. Smart contracts deployed on Ethereum cannot be directly deployed on Arbitrum without special handling. The differences between the two are crucial, as certain scenarios might not work, and security could be significantly compromised. Therefore, when deploying smart contracts, it’s essential to redeploy them on the Arbitrum testnet.

Since smart contracts need to be deployed, testnet ETH is necessary.

Obtaining Arbitrum Sepolia ETH Test Tokens

Some users obtain free ETH test tokens from the Arbitrum Sepolia faucet. However, the amount provided by the faucet is minimal, and the process can be tedious, requiring account registration and Twitter activity. Given the rising difficulty in acquiring ETH test tokens, they have become increasingly valuable on the Arbitrum Sepolia Testnet, so it is advised to use them carefully.
