# EVM

GameSwift Chain is built on the Bedrock release of the OP Stack, designed to closely resemble Ethereum. As a result, there are minimal differences between developing on GameSwift Chain and Ethereum.

However, there are still some minor discrepancies between the behavior of GameSwift Chain and Ethereum that you should be aware of when building apps on GameSwift Chain.
