Base, a Coinbase Layer 2 network, has made its code and smart contracts open source, promoting transparency and community contributions. This move provides developers with complete access to the code and aims to provide more insight into project development. All smart contracts and scripts are now available on GitHub, allowing developers to assess and experiment with deposit and withdrawal functions. While open-source development improves security through community scrutiny, Coinbase is offering a $1 million bug perk to security-minded developers. Base has also open-sourced web properties.
