METAPLEX(TM) NFT OPEN SOURCE LICENSE
Version 1.0, Oct. 2022
PREAMBLE
As the publisher of the non-fungible token (NFT) standard for the Solana
blockchain, we believe in the set of principles that have guided open source
software development models over the years – Transparency, Collaboration,
Release Early and Often, Community, and Inclusive Meritocracy. Thus, for our
code repository, we have adopted an “Apache-style” licensing scheme. To be
true to our NFT and crypto legacy, however, we do impose some restrictions on
modifying our code that we believe promote the purpose and promise of NFTs in
order to protect the web3 ecosystem.

the License.
------
“Derivative Works” means any work, whether in Source Code or Object Code,

such license applies only to those patent claims licensable by such
Contributor that are necessarily infringed by their Contribution(s) alone or
by combination of their Contribution(s) with the Work to which such
Contribution(s) was submitted. If You institute patent litigation against any
entity (including a crossclaim or counterclaim in a lawsuit) alleging that the
Work or a Contribution incorporated within the Work constitutes direct or
contributory patent infringement, then any patent licenses granted to You under
this License for that Work shall terminate as of the date such litigation is
