- Define constants for contract owner, admin, and various error codes. - Introduce a data variable for tracking the next asset ID. - Create an asset registry map to store asset details including owner, total supply, fractional shares, metadata URI, transferability, and creation timestamp. This commit sets up the foundational elements for the AssetBridge protocol, enabling compliant tokenization and secure fractional ownership of real-world assets.
- Define maps for compliance status and share ownership to track asset approval and ownership details. - Introduce a non-fungible token (NFT) for asset ownership. - Implement event logging with a private function to record events related to asset transactions. This commit enhances the AssetBridge protocol by adding compliance tracking, share ownership management, and detailed event logging capabilities.
- Implement private validation functions to check the validity of metadata URIs, asset IDs, and principals. - Add a private function to verify compliance checks for asset transfers. - Introduce a private function to retrieve the number of shares owned by a principal for a specific asset. These additions enhance the protocol's ability to validate inputs and manage share ownership effectively.
- Implement `create-asset` public function to create new assets with total supply, fractional shares, and metadata URI. - Validate inputs for total supply, fractional shares, and metadata URI. - Initialize share ownership and mint NFT for asset ownership. - Log asset creation events and update the next asset ID. This commit enables the creation of new assets with proper validation, ownership initialization, and event logging.
- Implement `set-compliance-status` public function to update compliance status for assets. - Validate asset ID, user principal, and authorization before updating compliance status. - Log compliance update events. - Add read-only functions to retrieve asset details, owner shares, compliance details, and event information. This commit enhances the protocol by enabling compliance status management and providing read-only access to important asset and event data.
…ight - Correct all instances of `block-height` to `stacks-block-height` for accurate timestamping in event logging and compliance status updates. This fix ensures that the protocol uses the correct reference for block height, aligning with Stacks' blockchain terminology.
…age examples - Introduce AssetBridge protocol overview, highlighting its capabilities for real-world asset tokenization. - Detail key features including asset creation, fractional ownership, security, compliance, and ownership management. - Describe the technical architecture and core components such as asset registry, compliance system, share management, and event system. - Provide smart contract interface documentation with public and read-only functions. - Include error handling constants and security considerations. - Add usage examples for creating new assets and transferring shares. - Outline development setup and contributing guidelines. This README.md serves as comprehensive documentation for developers and users of the AssetBridge protocol.

Overview
This PR introduces AssetBridge, a sophisticated smart contract protocol built on Stacks that enables compliant tokenization of real-world assets with secure fractional ownership capabilities. The protocol leverages Bitcoin's security through Stacks' PoX consensus and provides institutional-grade features for asset management.
