Open Cap Table Protocol (OCP)

This repository implements the Open Cap Table Protocol (OCP) for managing cap tables on-chain. It adheres to the Open Cap Format (OCF) standard for data modeling and validation. OCP supports managing cap tables across multiple EVM-compatible chains.

Repo Organization

• src/ → Server files (routes, MongoDB, etc.)
• chain/ → Smart contracts (Diamond pattern with facets)

Prerequisites

Ensure you have the following installed:

• Forge
• Node.js
• Yarn

Setup & Running Locally

1. Copy .env.example to .env.local. (The example file includes a local database setup for testing, which we recommend.)

Setup

1. Install dependencies:

   yarn install

2. You should see the factory contracts successfully deployed.

3. Start services:

   • Terminal 1: Start Anvil (local blockchain)

     anvil

     • Take one of the output's "Private Keys" and set your env file's PRIVATE_KEY

   • Terminal 2: Deploy contracts

     yarn deploy:local

     • Set your env file's variables using output of deploy script

       DIAMOND_CUT_FACET=
       ISSUER_FACET=
       STAKEHOLDER_FACET=
       STOCK_CLASS_FACET=
       STOCK_FACET=
       CONVERTIBLES_FACET=
       EQUITY_COMPENSATION_FACET=
       STOCK_PLAN_FACET=
       WARRANT_FACET=
       STAKEHOLDER_NFT_FACET=

   • Terminal 3: Run the mongo instance

     docker compose up

   • Terminal 4: Run the backend server

     yarn dev

Multi-Chain Support

This repository supports deploying cap tables to different EVM chains.

• Check /src/chains.js and configure the required chain keys.
• When making API requests:
  • Issuer creation → Pass chainId in the request body.
  • Other transactions (e.g., creating stakeholders, issuing stock) → Pass issuerId in the request body.
• See /src/routes for implementation details.

Usage

1. Create an issuer first.
2. Add stakeholders, stock classes, and other relevant data.
3. For quick testing, use the example script:

   node src/examples/testTransfer.mjs

Resetting Local Testing

If you are frequently testing locally, reset the database before redeploying:

yarn deseed

Deployment

Use the appropriate command to deploy contracts:

• Local:

  # Clear envvars in .env.local if they exist from a previous deployment
  yarn deploy:local

• Testnet:

  yarn deploy:testnet

• Mainnet:

  yarn deploy:mainnet
