The T-REX protocol ERC3643 is a compliance token standard for real-world asset tokenization. It aims to achieve compliance check and identity management for asset transfers through smart contracts. With the popularization of the concept of RWA (Real World Asset Tokenization), ERC3643 is expected to become a key technical standard in this field and gradually become popular because it can meet regulatory needs and ensure transaction security.
Developed by the ERC3643 Association (formerly Tokeny), this standard aims to provide a compliant and interoperable framework for regulated security-based tokens. Core functions include identity verification, transfer restrictions and compliance checks to ensure that tokenized assets comply with global securities regulations. Development process ERC-3643 was formerly known as the T-REX protocol, which was upgraded to a standardization proposal after years of practice and community feedback.

ERC3643 (now known as ERC-3643) was not "created" in a given year, but was finally confirmed in October 2023 during the standardization process as the Ethereum Improvement Proposal (EIP). The standard is promoted by the association "ERC3643"(formerly known as the T-REX Protocol Association), and its core specifications will be gradually improved and submitted to the community for review between 2022 and 2023.
ERC-3643 (now known as the T-Rex protocol) was developed by Tokeny Solutions and was officially adopted as an official standard by the Ethereum community in 2023 and will be fully launched in July 2025. On July 31, 2025, SEC Chairman Paul Atkins publicly cited the standard when announcing the "Project Crypto" plan, emphasizing its importance for compliant digital asset issuance.

1. In AutoCAD, object capture is an extremely important tool. It helps users locate accurately and directly uses the cursor to accurately determine target points, such as center center, end points, foot, etc. Users can enable object snap mode in several ways: (1) Use the "Object Snap" toolbar. (2) Press the Shift key and right-click to pop up the shortcut menu. (3) Enter the corresponding abbreviation in the command.
2."Perpendicular": abbreviated as "PER", used to capture the vertical point from a specified point to another object. (10)"Parallel": abbreviated as "PAR", used to capture a point in a direction parallel to the specified line.
3. In 3dmax, better capture settings include the following: Grid capture: Introduction: Turning on grid capture can help users move the model more accurately. Function: The model will automatically adhere to the grid when moving to avoid positional deviations. Object Snap: Introduction: Suitable for situations where you need to align a part of one model to a part of another model.

The steps to make smoothing groups and set soft and hard edges in Maya are as follows: Set up smoothing groups to open the model: First, make sure you have opened a Maya scene that contains the model you want to edit. Enter the Polygon module: At the top of Maya's interface, find and click the "Modeling" menu, and then select the "Polygon" module. This is the main workspace for polygon editing. Select Model: Select the model in the view for which you want to set the smoothing group.

How to set up smoothing groups and soft and hard edges in Maya is as follows: Set the smoothing group to open the model: First, open the model you want to edit in Maya. Ensure that the model has been imported and is editable. Enter the Polygon module: At the top of Maya's interface, find and click the "Modeling" menu, and then select "Polygon" to enter the polygon editing module.
Set smoothing groups to open a model: First, make sure you have opened a model that contains smoothing groups you need to set. Select Model: Select the part or entire model in the view for which you want to set smoothing groups. Enter the Polygon module: In the upper menu bar of the Maya interface, click the "Modeling" menu, and then select the "Polygon" module.
