With this in mind, Uniswap v3 Core will launch under the Business Source License 1.1—effectively a time-delayed GPL-2.0-or-later license. The license limits use of the v3 source code in a commercial or production setting for up to two years, at which point it will convert to a GPL license into perpetuity.
Uniswap governance can accelerate the change to GPL or grant exemptions to the license at any time by updating the files at v3-core-license-date.uniswap.eth and v3-core-license-grants.uniswap.eth .
Note that the BUSL 1.1 license does not affect integrations. All code that may be needed for external integrations has been licensed under GPL or MIT , including math libraries, peripheral contracts, interfaces, and the developer sdk. Any wallet, interface, mobile app, protocol, or other project will be able to integrate with v3 as expected.
