Developers are now allowed to fork Uniswap v3 protocol as its Business Source License (BSL) expired on April 1, shows protocol documentation. The expiration was a much-anticipated event within the decentralized finance (DeFi) ecosystem, enabling developers to deploy their own decentralized exchange (DEX).
The BSL license lasts for a limited period before becoming completely open source. The purpose is to protect the author’s right to profit from their creations. Uniswap v3’s license was released in 2021 for two years, preventing its code from commercial use. A new license called a “General Public License” now applies to the protocol.
