What Was ETHDenver 2023?
ETHDenver 2023 was the world's largest and longest-running Ethereum hackathon, held in Denver, USA, from 24 February to 5 March 2023. Part festival, part hackathon, part conference, it drew thousands of developers, founders, artists, and Web3 enthusiasts for an epic stretch of building, learning, and community. The official page sat on the ETHDenver site. As a builder-first mega-event, it sits at the heart of Ethereum culture.

Key Themes at ETHDenver
The agenda matched a huge builder crowd:

- DeFi, NFTs, and public goods.
- Identity, ZK, and infrastructure.
- Community and culture.
Its scale and energy are unmatched. Many guests also tracked broader blockchain events through CoinGabbar.
How Crypto Is Growing in the United States
The United States is the centre of gravity for crypto, with the deepest pool of capital, developers, and projects anywhere. Policy turned notably friendlier into 2024 and 2025: spot Bitcoin and Ethereum exchange-traded funds went live in 2024, bringing traditional money onchain, and the 2025 GENIUS Act created the first federal framework for stablecoins. Crypto is legal but not legal tender.
For an Ethereum mega-hackathon, the US ecosystem is unbeatable, a vast base of builders, investors, and users all in one market. Denver in particular has become a beloved host, its winter timing and community spirit giving ETHDenver a distinctive, grassroots culture even as it scaled to thousands of attendees. The event predates the friendlier regulatory era, but it helped seed many of the teams now building in a more mature US market. For builders, ETHDenver remains one of the best places on earth to start an Ethereum project. For more shows, see CoinGabbar's US crypto events page.
