Coinbase—Coinbase launched Base Layer 2 blockchain and open-sourced its code, smart contracts, and web properties
Coinbase launched the Base mainnet on August 9, 2023, an Ethereum Layer 2 blockchain built on the open-source OP Stack in collaboration with Optimism. In October 2023, Base open-sourced its code repositories, smart contracts, and web properties (base.org, docs.base.org, bridge.base.org) to increase transparency and allow public contributions. Base grew to become the largest Layer 2 network by total value locked. Coinbase also offered up to $1M in bug bounties through HackerOne and outlined a decentralization roadmap including fault proofs and diverse client software for censorship resistance.
