Twin3 SDK Proprietary License

Copyright (c) 2026 Twin3 AI Limited (the "Licensor"). All rights reserved.

This software, together with its documentation, specifications, protocol
designs, test vectors, and cryptographic constructions (the "Software"), is the
proprietary property of the Licensor. It is not open-source software. Making a
distribution artifact publicly downloadable from a package registry or source
host does not place the Software in the public domain, does not grant any
open-source licence, and does not waive any right reserved below.

1. Limited licence
   Subject to continuous compliance with these terms, the Licensor grants you a
   personal, non-exclusive, non-transferable, non-sublicensable, revocable
   licence to download, install, and execute unmodified official distribution
   artifacts of the Software, solely to evaluate the Software and to build and
   operate applications that interoperate with it.

2. Restrictions
   Except where applicable law expressly prohibits such a restriction, you may
   not: copy the Software beyond what is required to exercise the licence in
   section 1; modify, adapt, translate, or create derivative works of the
   Software; redistribute, publish, sublicense, sell, rent, lease, or provide
   the Software to any third party, whether standalone or embedded in another
   product or service; remove, obscure, or alter any proprietary or attribution
   notice; or reverse engineer, decompile, or disassemble the Software.

3. Reservation of rights
   All rights not expressly granted in section 1 are reserved by the Licensor,
   including every copyright, patent, trade secret, trademark, database, and
   other intellectual property right in the Software. No patent licence is
   granted by implication, estoppel, or otherwise. No trademark licence is
   granted.

4. Contributions and derivative work
   Nothing in this licence grants any right to fork the Software, publish a
   derivative of it, or contribute to it. Any such activity requires prior
   written permission from the Licensor.

5. Termination
   This licence terminates automatically and immediately upon any breach of
   these terms. On termination you must stop using the Software and destroy all
   copies in your possession or control. Sections 2, 3, 6, 7, and 8 survive
   termination.

6. No warranty
   THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR
   IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY,
   FITNESS FOR A PARTICULAR PURPOSE, TITLE, AND NON-INFRINGEMENT. THE SOFTWARE
   IMPLEMENTS SECURITY AND SETTLEMENT PROTOCOLS; THE LICENSOR DOES NOT WARRANT
   THAT IT IS FREE OF DEFECTS OR FIT FOR ANY PARTICULAR DEPLOYMENT.

7. Limitation of liability
   TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, THE LICENSOR SHALL NOT BE
   LIABLE FOR ANY CLAIM, DAMAGES, OR OTHER LIABILITY, WHETHER IN AN ACTION OF
   CONTRACT, TORT, OR OTHERWISE, ARISING FROM, OUT OF, OR IN CONNECTION WITH THE
   SOFTWARE OR ITS USE, INCLUDING ANY INDIRECT, INCIDENTAL, SPECIAL,
   CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES, OR ANY LOSS OF PROFITS,
   REVENUE, DATA, OR DIGITAL ASSETS.

8. Entire terms
   These terms are the entire licence for the Software and supersede any prior
   or contemporaneous understanding. A separate written agreement signed by the
   Licensor may grant broader rights; only that agreement can vary these terms.

above, contact core@twin3.ai.
