In simple English
This tool helps companies track who owns their shares using both public blockchain records and a regular database. It follows official standards for keeping legal share records compliant with American rules. You need some technical knowledge to set up databases, blockchain wallets, and local servers. The software is free to use right now under a source-available licence that turns open source later. It is meant for founders and developers building digital equity systems.
What it is
An open-source project combining Solidity smart contracts (programs that run automatically on a blockchain) with a Node.js API (a server that lets different programs talk to each other) server. It stores company share data onchain while keeping offchain databases compliant with transfer agent rules.
