EVM Compatibility & Infrastructure

What are the opcode differences on Scroll compared to Ethereum?

Scroll is fully EVM-equivalent, but certain rollup-specific opcodes differ. A full breakdown can be found here: Rollup Codes: Scroll Overview.

Testnet ETH

How do I get testnet ETH on Scroll?

You can request testnet ETH via the official Scroll telegram faucet bot by sending a message to @scroll_up_sepolia_bot who will provide access to the faucet. Once on the faucet telegram group chat, send your wallet address on a /drop YOUR_ETHEREUM_ADDRESS command and the bot will automatically send some funds to you.

Is there an alternative way to get testnet ETH?

Yes. Please refer to our list of Unofficial Faucets on both Sepolia and Scroll Sepolia. Remember, you can either receive Scroll Sepolia ETH directly or trough the Sepolia Testnet Bridge.
