Super Durable Source License 1.0

Copyright (c) 2026 Super Durable, Inc.

Acceptance

This agreement governs the Software made available by Super Durable, Inc.
("Licensor"). By copying, modifying, distributing, or using the Software, You
accept this agreement. If You act for an entity, You represent that You have
authority to bind that entity, and "You" means that entity.

License Grant

Subject to this agreement, Licensor grants You a non-exclusive, worldwide,
non-transferable, non-sublicensable license to copy and modify the Software and
to use it for Non-Production Use.

Licensor also grants You a license to make Production Use when either:

1. You are a Qualified User; or
2. You have a current Subscription authorizing that Production Use.

If You cease to be a Qualified User, You may continue the same Production Use
for ninety (90) days after the end of the first fiscal year for which Your
Consolidated Annual Revenue exceeds the Revenue Threshold. After that grace
period, continued Production Use requires a Subscription.

The licenses in this section include the right to make, have made, use, sell,
offer for sale, and import the Software only under patent claims Licensor can
license that are necessarily infringed by the Software as provided by
Licensor. If You bring a written patent infringement claim concerning the
Software, this patent license terminates immediately.

Applications and Client Components

While otherwise complying with this agreement, You may distribute Client
Components, in source or object form, solely as an embedded or bundled part of
an Application. The Application must have a primary purpose other than
providing the Software, a Competitive Product, or a hosted Dex-compatible
service.

A recipient may run an Application containing Client Components without a
separate Subscription. This exception does not permit the recipient to extract,
modify, redistribute, or use Client Components independently, or to deploy or
operate other Software. A person that develops or operates an Application is
still subject to the Production Use and Revenue Threshold requirements.

Competitive Use

You may not make Competitive Use without a separate written commercial license
from Licensor. The Revenue Threshold, Qualified User status, grace period, and
Application exception do not authorize Competitive Use.

Source Collaboration

You may publicly host a source fork or distribute patches solely for
evaluation, internal development, or contribution to Licensor, provided You:

1. do not make Production Use or Competitive Use through that distribution;
2. preserve this agreement and all copyright, attribution, and license notices;
3. identify files You modified; and
4. apply this agreement to Your modifications to the Software.

No other redistribution of the Software or a Modified Version is permitted
except under the Application exception or a Subscription.

Legacy and Third-Party Materials

This agreement applies only to the Software and modifications owned or
licensable by Licensor. It does not replace or restrict any license applying to
Legacy Materials or Third-Party Materials. Those materials remain governed by
their respective licenses. Their notices and license texts must be preserved.
See LEGACY_NOTICES.md and accompanying third-party notices.

Commercial Licenses

A Subscription or other written commercial agreement may grant additional
rights. If its terms conflict with this agreement, the commercial agreement
controls only for the Software, use, and period it expressly covers. Contact
licensing@superdurable.io for a Subscription or Competitive Use license.

Restrictions and Obligations

You must not:

1. remove or obscure copyright, license, attribution, or trademark notices;
2. represent that Licensor endorses You or Your products;
3. use Licensor's names, marks, or logos except to accurately identify the
   origin of the Software; or
4. enable another person to exercise rights that this agreement does not grant.

You are responsible for Your affiliates, contractors, and agents that use the
Software on Your behalf. You must comply with applicable export, import, and
sanctions laws.

Termination

Your rights terminate automatically if You breach this agreement. If the breach
is capable of cure and is neither intentional nor repeated, Your rights are
reinstated retroactively when You cure it within fifteen (15) days after the
breach. Intentional or repeated breaches permanently terminate Your rights
unless Licensor agrees otherwise in writing.

No Other Rights

Except for rights expressly granted here, Licensor reserves all rights. This
agreement grants no trademark rights and does not require Licensor to provide
support, maintenance, updates, or a Subscription.

Disclaimer

TO THE MAXIMUM EXTENT PERMITTED BY LAW, THE SOFTWARE IS PROVIDED "AS IS" AND
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING
MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, NON-INFRINGEMENT,
ACCURACY, OR UNINTERRUPTED OR ERROR-FREE OPERATION.

Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, LICENSOR WILL NOT BE LIABLE FOR ANY
INDIRECT, SPECIAL, INCIDENTAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES,
OR FOR LOST PROFITS, REVENUE, DATA, OR BUSINESS INTERRUPTION. LICENSOR'S TOTAL
LIABILITY ARISING FROM THIS AGREEMENT OR THE SOFTWARE WILL NOT EXCEED ONE
HUNDRED U.S. DOLLARS (US$100), REGARDLESS OF THE LEGAL THEORY AND EVEN IF
LICENSOR WAS ADVISED THAT SUCH DAMAGES WERE POSSIBLE.

Governing Law

Delaware law and applicable United States federal law govern this agreement,
without regard to conflict-of-law rules. The state and federal courts located
in Delaware have exclusive jurisdiction. The United Nations Convention on
Contracts for the International Sale of Goods does not apply.

"Application" means software developed for a business or end-user purpose whose
primary purpose is not to provide the Software or a Competitive Product.

"Client Components" means the SDK and protocol-definition portions of the

"Competitive Product" means software or a service whose primary purpose is to
replace or provide substantially similar functionality to a Dex server, Dex
SDK, Dex command-line product, Dex web product, or a hosted Dex-compatible

used in the applicable consolidated financial statements. If You have no
completed fiscal year, use a good-faith annualization of revenue since formation.

merge commit, and later copies or adaptations of that material, to the extent
governed by a license other than this agreement.

"Modified Version" means any modification or derivative work of the Software.

"Non-Production Use" means design, prototyping, evaluation, testing, or
development that does not serve live end users, process live business workloads,
or support production operations.

the Revenue Threshold and You are not making Competitive Use.

"Revenue Threshold" means ten million U.S. dollars (US$10,000,000).

"Software" means files in this repository that include or refer to this
agreement, in source or object form, excluding the docs/ and examples/
directories, Legacy Materials, and Third-Party Materials.

Licensor that authorizes the applicable Production Use.
