The Apache License, Version 2.0, under which the TrustLedger source code is distributed, does not grant permission to use the Operator's trade names, trademarks, service marks, or product names except as required for describing the origin of the software.

• Any stylized or composite marks combining "TrustLedger" with other words or

graphics

• The overall visual identity, color palette, and trade dress of the Platform
• Any future marks adopted by the Operator in connection with the Platform

These Marks may or may not be registered. Whether registered or not, all rights are reserved and unauthorized use constitutes infringement of the Operator's intellectual property rights.

3. Permitted Uses

3.1 Nominative Fair Use. You may refer to TrustLedger by name in the following limited circumstances, provided You do not imply sponsorship or endorsement:

(a) identifying the TrustLedger software when distributing the Licensed Code pursuant to the Apache License (e.g., "This software is based on TrustLedger");

(b) truthful, factual references to TrustLedger in academic, journalistic, or educational materials (e.g., "TrustLedger is an open-source escrow platform");

(c) accurately describing that Your product or service is compatible with or integrates with TrustLedger's open-source code (e.g., "Compatible with TrustLedger's Escrow Contract ABI"), provided such reference does not imply official endorsement; and

(d) preserving copyright and attribution notices as required by the Apache License.

3.2 Open-Source Attribution. When distributing the Licensed Code or derivative works, You must retain all copyright notices, the NOTICE file, and references to TrustLedger's origin as required by the Apache License. Such retention is required and permitted.

4. Prohibited Uses

You may not, without the prior written consent of the Operator:

(a) use the Marks as part of Your own product, service, company, or project name (e.g., "TrustLedger Pro," "MyTrustLedger," or "TrustLedger Analytics");

(b) use the Marks on any website, app, or platform in a manner that implies official endorsement, affiliation, or sponsorship by the Operator;

(c) modify, stylize, distort, animate, or create derivative versions of the Marks, including changing colors, proportions, or adding graphic elements;

(d) use the Marks in domain names, social media handles, usernames, app store listings, browser extensions, ENS names, or similar identifiers (e.g., "trustledger.xyz," "@trustledger_official");

(e) use the Marks on merchandise, promotional materials, or physical goods;

(f) use the Marks in a way that is derogatory, tarnishing, or damaging to the Operator's reputation or goodwill;

5. Open-Source Forks and Derivatives

The Apache License permits You to fork, modify, and distribute the Licensed Code. However:

(a) Your fork or derivative project must use a different name and brand identity that is not confusingly similar to "TrustLedger" or any of the Marks.

(b) You must clearly distinguish your fork or derivative as unofficial and unaffiliated with the Operator.

(c) Permissible attribution (e.g., "Based on TrustLedger") must be accurate, factual, and not displayed in a manner that implies endorsement.

(d) You must not represent Your fork or derivative as being the same as or better than the "official" TrustLedger Platform in ways that trade on the goodwill of the Marks.
