-# Description
-
-Asset Tokenization Studio (ATS) is a suite designed to enable the creation, management, and trading of security tokens on the Hedera network.
-
-The ATS facilitates the tokenization of traditional financial assets (equities and bonds) onto the Hedera distributed ledger, providing a framework for:
-
-- Creating and deploying security tokens
-- Managing token lifecycles
-- Implementing compliance and regulatory requirements
-- Enabling secure token transfers and operations
+## Introduction
-## Monorepo Structure
-
-The project is organized as a monorepo using npm workspaces:
-
-```
-├── packages/ # Core packages
-│ ├── ats/
-│ │ ├── contracts/ # Smart contracts deployed on Hedera
-│ │ └── sdk/ # TypeScript SDK for contract interaction
-│ └── mass-payout/ # Mass payout functionality
-├── apps/ # Applications
-│ ├── ats/
-│ │ └── web/ # React web application
-│ └── mass-payout/ # Mass payout app
-└── package.json # Root workspace configuration
-```
+The **Asset Tokenization Studio (ATS) Monorepo** provides a unified environment to design, deploy, and operate tokenized financial assets on the **Hedera network**, as well as to manage **large-scale payout distributions**.
-The ATS consists of three primary components that work together to provide a complete tokenization solution:
+It brings together two complementary suites:
-- **Smart Contracts** (`packages/ats/contracts`) - The on-chain components deployed on the Hedera network
-- **SDK** (`packages/ats/sdk`) - A software development kit that provides programmatic access to the contracts
-- **Web Application** (`apps/ats/web`) - A user interface for interacting with the tokenized assets
+- **Asset Tokenization Studio (ATS):** Tools for creating, managing, and interacting with **security tokens** (equities and bonds) that comply with enterprise-grade standards.
+- **Scheduler Payment Distribution (Mass Payout):** Infrastructure to execute **batch payments** (e.g., dividends, bond coupons, recurring obligations) efficiently across thousands of accounts.
-The standard ERC for security tokens used in the smart contracts is ERC1400.
+This monorepo is structured with **npm workspaces** and is designed for scalability, modularity, and enterprise adoption.
-Version 1.15.0 introduces partial compatibility with the ERC-3643 (TREX) standard; full support will follow in upcoming releases.
+---
-# Development manifesto
+## Key Features
-The development of the project follows enterprise-grade practices for software development. Using DDD, hexagonal architecture, and the CQS pattern, all within an agile methodology.
+- **Tokenization Framework**
+ - Security tokens compliant with **ERC-1400** and partial support for **ERC-3643 (T-REX)**.
+ - Modular **diamond pattern architecture** for upgradeability.
+ - Identity registry, compliance modules, and granular freeze controls.
+ - Role-based access control with administrative and operational roles.
-## Domain driven design
+- **Mass Payout Framework**
+ - Batch operations optimized for large-scale distributions.
+ - Supports both **HBAR** and **HTS tokens**.
+ - Lifecycle cash flow management for recurring obligations.
+ - Gas-optimized operations and proxy-based upgradeable contracts.
-By using DDD (Domain-Driven Design), we aim to create a shared language among all members of the project team, which allows us to focus our development efforts on thoroughly understanding the processes and rules of the domain. This helps to bring benefits such as increased efficiency and improved communication.
+- **Enterprise Development Practices**
+ - **Domain-Driven Design (DDD)**, **Hexagonal Architecture**, and **CQS pattern**.
+ - Separation of concerns across smart contracts, SDKs, frontends, and backends.
+ - Strong CI/CD workflows with conditional builds and tests for each module.
+ - Custodian integration at the SDK level (Dfns, Fireblocks, AWS KMS).
-## Token Standards Support
+## Monorepo Structure
-The Asset Tokenization Studio supports multiple security token standards:
+```
+├── packages/
+│ ├── ats/
+│ │ ├── contracts # Solidity smart contracts for ATS
+│ │ └── sdk # TypeScript SDK for ATS contracts
+│ └── mass-payout/
+│ ├── contracts # Solidity smart contracts for payout flows
+│ └── sdk # TypeScript SDK for payout flows
+├── apps/
+│ ├── ats/
+│ │ └── web # Frontend dApp for Asset Tokenization Studio
+│ └── mass-payout/
+│ ├── backend # API backend for payout orchestration
+│ └── frontend # Admin panel for managing payouts
+└── package.json # Workspace configuration and root scripts
+```
-- **ERC1400**: Core security token standard with partition-based token management
-- **ERC3643 (T-REX)**: Advanced compliance framework with identity registry, compliance modules, and sophisticated freeze capabilities

-# Prerequisites
+## Installation & Setup
-Ensure the following tools are installed:
+### Prerequisites
-- **Node:** v20.19.4 (LTS: Iron) or newer
-- **NPM :** v10.8.2 or newer
+- Node.js
+ - ATS requires v20.19.4 or newer
+ - Mass Payout backend requires v24.0.0 or newer
+- npm v10.9.0 or newer
+- PostgreSQL (for the Mass Payout backend)
-# Installation
+### Quick Setup
-This project uses npm workspaces for dependency management. In a terminal at the root directory:
+From the monorepo root:
```bash
+
+# Install all dependencies
npm ci
```
-This will install all dependencies for all workspaces and automatically set up the links between packages.
+```bash
+# Build all packages and applications
+npm run setup
+```
-You can now start developing in any of the workspace modules.
+This command will compile contracts, build SDKs, and set up web and backend environments.
-# Workspace Overview
+### Environment Configuration
-This monorepo uses npm workspaces to manage dependencies and build processes across multiple packages and applications.
+Each application has its own .env configuration file.
-## Available Workspace Commands
+- ATS Web App: apps/ats/web/.env.local
+ Defines Hedera endpoints, resolver and factory IDs, and WalletConnect settings.
-### ATS (Asset Tokenization Studio)
+- Mass Payout Backend: apps/mass-payout/backend/.env
+ Includes PostgreSQL connection and runtime configuration.
-```bash
-# Build commands
-npm run ats:build # Build all ATS components
-npm run ats:contracts:build # Build smart contracts only

-npm run ats:publish # Publish contracts and SDK to npm
-```
+- Mass Payout Frontend: apps/mass-payout/frontend/.env
+ Requires VITE_API_URL and VITE_PORT.
-### Mass Payout (Placeholder)
+Sample files are provided (.env.sample or .env.example) in each module.
-```bash
-npm run mass-payout:build # Build mass payout components
-npm run mass-payout:test # Test mass payout components
-npm run mass-payout:dev # Start mass payout development
-```
+## Development Workflows
-### Utility Commands
+### ATS
```bash
-npm run clean:deps # Remove all node_modules and lock files
-npm run lint # Lint all code using centralized configuration
-npm run format # Format all code using centralized Prettier config
+npm run ats:build # Build contracts, SDK, and web app
+npm run ats:start # Start web app (with contracts & SDK built)
+npm run ats:test # Run tests for all ATS modules
```
-## Workspace Dependencies
+- Contracts (packages/ats/contracts) → Solidity, Hardhat, diamond pattern
+- SDK (packages/ats/sdk) → TypeScript SDK for client and web integration
+- Web App (apps/ats/web) → React 18 frontend for asset management
-The workspaces have the following dependency relationships:
+### Mass Payout
-```
-packages/ats/contracts → (standalone)
-packages/ats/sdk → depends on contracts
-apps/ats/web → depends on SDK (and transitively contracts)
+```bash
+npm run mass-payout:build # Build contracts, SDK, backend, and frontend
+npm run mass-payout:backend:dev # Start backend in dev mode
+npm run mass-payout:frontend:dev # Start frontend in dev mode
+npm run mass-payout:test # Run all payout-related tests
```
-When you run workspace commands, npm automatically handles building dependencies in the correct order.
+- Contracts (packages/mass-payout/contracts) → Solidity payout contracts
+- SDK (packages/mass-payout/sdk) → TypeScript SDK for payout execution
+- Backend (apps/mass-payout/backend) → API with PostgreSQL
+- Frontend (apps/mass-payout/frontend) → Admin panel in React + Chakra UI
-# Build
+## Testing
-The project uses workspace-aware build commands. When making modifications to any module, rebuild the dependencies in the following order:
+Run tests for all modules:
```bash
-# Build all ATS components (recommended)
-npm run ats:build
-
-# Or build individual components:
-npm run ats:contracts:build # 1st - Smart contracts
-npm run ats:sdk:build # 2nd - SDK (depends on contracts)
-npm run ats:web:build # 3rd - Web app (depends on SDK)
-
-# Mass Payout (when available)
-npm run mass-payout:build
+npm run ats:test
+npm run mass-payout:test
```
-# Setting Up the Environment

+### SDKs
-## Steps to set up the `.env` file:
+- TypeScript APIs for deploying and managing securities, payouts, compliance, and lifecycle events
+- Batch operations for minting, burning, freezing, and payouts
-1. Navigate to the `apps/ats/web` directory.
-2. Copy the `.env.sample` file to create a new `.env` file:
+### Applications
- ```bash
- cp .env.sample .env
- ```
-
-3. Open the `.env` file in your preferred text editor.
-4. Replace the placeholder values with your actual environment settings. For example:
-
- ```bash
- REACT_APP_EQUITY_CONFIG_ID='0x0000000000000000000000000000000000000000000000000000000000000001'
- REACT_APP_EQUITY_CONFIG_VERSION="0"
- REACT_APP_BOND_CONFIG_ID="0x0000000000000000000000000000000000000000000000000000000000000002"
- REACT_APP_BOND_CONFIG_VERSION="0"
- REACT_APP_SHOW_DISCLAIMER="true"
-
- REACT_APP_MIRROR_NODE="https://testnet.mirrornode.hedera.com/api/v1/"
- REACT_APP_RPC_NODE="https://testnet.hashio.io/api"
- REACT_APP_RPC_RESOLVER='0.0.6797832'
- REACT_APP_RPC_FACTORY='0.0.6797955'
-
- REACT_APP_PROJECT_ID="your_project_id_from_walletconnect"
- REACT_APP_DAPP_NAME="Asset Tokenization Studio"
- REACT_APP_DAPP_DESCRIPTION="Asset Tokenization Studio. Built on Hedera Hashgraph."
- REACT_APP_DAPP_URL="https://wc.ats.com/"
- REACT_APP_DAPP_ICONS='["https://stablecoinstudio.com/static/media/hedera-hbar-logo.4fd73fb360de0fc15d378e0c3ebe6c80.svg"]'
- ```
-
-5. Save the file and proceed with running the application.
-
-## Critical Setup Recommendation for Optimal Performance
-
-For the best experience, we strongly recommend installing the [hiero-json-rpc-relay](https://github.com/hiero-ledger/hiero-json-rpc-relay/tree/main) on your local machine. The hashio API (`REACT_APP_RPC_NODE="https://testnet.hashio.io/api"`) has rate limits that may cause errors during operations. By setting up the relay locally, you can replace the `REACT_APP_RPC_NODE` environment variable with a local endpoint (e.g., `REACT_APP_RPC_NODE="http://localhost:7546"`) to ensure stable and uninterrupted performance.
-
-## Key Features
+- **ATS Web**: dApp for asset issuance and management
+- **Mass Payout Backend**: Orchestrates scheduled payouts
+- **Mass Payout Frontend**: Admin dashboard for payout monitoring
-### ERC3643 Compliance Framework
+### Integrations
-The platform now includes comprehensive ERC3643 (T-REX) support featuring:
-
-- **Identity Registry**: Manage investor identities and compliance status
-- **Compliance Module**: Configurable compliance rules and restrictions
-- **Advanced Freeze Capabilities**: Partial token freezing and address-level freeze controls
-- **Agent Management**: Dedicated agent roles for compliance operations
-- **Batch Operations**: Efficient batch transfers, mints, burns, and freeze operations
-- **Recovery Address**: Account recovery mechanisms for lost access scenarios
-
-### Enhanced Token Operations
-
-- **Forced Transfers**: Controller-initiated transfers for regulatory compliance
-- **Batch Processing**: Multiple operations in single transactions for gas efficiency
-- **Granular Freeze Controls**: Freeze specific amounts or entire addresses
-- **Token Metadata Management**: On-chain token name, symbol, and metadata updates
-
-## Custodian Integration
-
-The ATS project utilizes a `custodians` library to facilitate interactions with various external custody providers.
-
-The integration with custodian services is **available at the SDK level only**, that means that the current implementation does not support direct dApp integration workflows and is limited to SDK tests right now. You can use your custodian providers using the .env file ([.env.sample](./sdk/.env.sample)).
-
-At the time the integration was first built, the SDKs provided by Dfns and Fireblocks did not yet support direct dApp integration workflows. Consequently, the current implementation focuses solely on SDK-based operations.
-
-### Supported Custodians and SDK Versions
-
-The following custody providers are supported through their respective SDKs within the ATS `custodians` library:
-
-- **Dfns:** SDK Version `0.1.0-beta.5`
-- **Fireblocks:** SDK Version `5.11.0`
-- **AWS KMS:** AWS SDK Version `3.624.0`
-
-For further details or assistance regarding the custodian integration, please consult the relevant source code within the SDK or reach out to the development team. [Custodians Library](https://github.com/hashgraph/hedera-custodians-library)

+ * unless required by applicable law (such as deliberate and grossly
+ * negligent acts) or agreed to in writing, shall any Contributor be
+ * liable to You for damages, including any direct, indirect, special,

+ * as modifying the License.
+ *
+ * You may add Your own copyright statement to Your modifications and

+ * agreed to in writing, Licensor provides the Work (and each
+ * Contributor provides its Contributions) on an "AS IS" BASIS,

+ * risks associated with Your exercise of permissions under this License.
+ *
+ * 8. Limitation of Liability. In no event and under no legal theory,
+ * whether in tort (including negligence), contract, or otherwise,
+ * unless required by applicable law (such as deliberate and grossly
+ * negligent acts) or agreed to in writing, shall any Contributor be
+ * liable to You for damages, including any direct, indirect, special,
+ * incidental, or consequential damages of any character arising as a
+ * result of this License or out of the use or inability to use the
+ * Work (including but not limited to damages for loss of goodwill,
+ * work stoppage, computer failure or malfunction, or any and all

+ * where such license applies only to those patent claims licensable
+ * by such Contributor that are necessarily infringed by their
+ * Contribution(s) alone or by combination of their Contribution(s)
+ * with the Work to which such Contribution(s) was submitted. If You

+ *
+ * (d) If the Work includes a "NOTICE" text file as part of its
+ * distribution, then any Derivative Works that You distribute must
+ * include a readable copy of the attribution notices contained
+ * within such NOTICE file, excluding those notices that do not
+ * pertain to any part of the Derivative Works, in at least one
+ * of the following places: within a NOTICE text file distributed
+ * as part of the Derivative Works; within the Source form or

+ * as modifying the License.
+ *
+ * You may add Your own copyright statement to Your modifications and
+ * may provide additional or different license terms and conditions
+ * for use, reproduction, or distribution of Your modifications, or

+ * agreed to in writing, Licensor provides the Work (and each
+ * Contributor provides its Contributions) on an "AS IS" BASIS,
+ * WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+ * implied, including, without limitation, any warranties or conditions
+ * of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+ * PARTICULAR PURPOSE. You are solely responsible for determining the
+ * appropriateness of using or redistributing the Work and assume any
+ * risks associated with Your exercise of permissions under this License.
+ *
+ * 8. Limitation of Liability. In no event and under no legal theory,
+ * whether in tort (including negligence), contract, or otherwise,
+ * unless required by applicable law (such as deliberate and grossly
+ * negligent acts) or agreed to in writing, shall any Contributor be
+ * liable to You for damages, including any direct, indirect, special,
+ * incidental, or consequential damages of any character arising as a
+ * result of this License or out of the use or inability to use the
+ * Work (including but not limited to damages for loss of goodwill,
+ * work stoppage, computer failure or malfunction, or any and all
+ * other commercial damages or losses), even if such Contributor
+ * has been advised of the possibility of such damages.
+ *
+ * 9. Accepting Warranty or Additional Liability. While redistributing
+ * the Work or Derivative Works thereof, You may choose to offer,
+ * and charge a fee for, acceptance of support, warranty, indemnity,
+ * or other liability obligations and/or rights consistent with this
+ * License. However, in accepting such obligations, You may act only
+ * on Your own behalf and on Your sole responsibility, not on behalf
+ * of any other Contributor, and only if You agree to indemnify,
+ * defend, and hold each Contributor harmless for any liability
+ * incurred by, or claims asserted against, such Contributor by reason
+ * of your accepting any such warranty or additional liability.
+ *
+ * END OF TERMS AND CONDITIONS

+ *
+ * 4. Redistribution. You may reproduce and distribute copies of the

+ * meet the following conditions:

+ * (a) You must give any other recipients of the Work or
+ * Derivative Works a copy of this License; and

+ * (d) If the Work includes a "NOTICE" text file as part of its

+ * pertain to any part of the Derivative Works, in at least one
+ * of the following places: within a NOTICE text file distributed

+ * as modifying the License.
+ *
+ * You may add Your own copyright statement to Your modifications and
+ * may provide additional or different license terms and conditions
+ * for use, reproduction, or distribution of Your modifications, or

+ * whether in tort (including negligence), contract, or otherwise,
+ * unless required by applicable law (such as deliberate and grossly
+ * negligent acts) or agreed to in writing, shall any Contributor be
+ * liable to You for damages, including any direct, indirect, special,

+ * agreed to in writing, Licensor provides the Work (and each
+ * Contributor provides its Contributions) on an "AS IS" BASIS,
+ * WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+ * implied, including, without limitation, any warranties or conditions
+ * of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A

+ * unless required by applicable law (such as deliberate and grossly
+ * negligent acts) or agreed to in writing, shall any Contributor be
+ * liable to You for damages, including any direct, indirect, special,

+ * where such license applies only to those patent claims licensable
+ * by such Contributor that are necessarily infringed by their
+ * Contribution(s) alone or by combination of their Contribution(s)

+ * 4. Redistribution. You may reproduce and distribute copies of the

+ * meet the following conditions:

+ * (a) You must give any other recipients of the Work or
+ * Derivative Works a copy of this License; and

+ * excluding those notices that do not pertain to any part of
+ * the Derivative Works; and
+ *
+ * (d) If the Work includes a "NOTICE" text file as part of its
+ * distribution, then any Derivative Works that You distribute must
+ * include a readable copy of the attribution notices contained
+ * within such NOTICE file, excluding those notices that do not
+ * pertain to any part of the Derivative Works, in at least one
+ * of the following places: within a NOTICE text file distributed
+ * as part of the Derivative Works; within the Source form or
+ * documentation, if provided along with the Derivative Works; or,
+ * within a display generated by the Derivative Works, if and
+ * wherever such third-party notices normally appear. The contents
+ * of the NOTICE file are for informational purposes only and
+ * do not modify the License. You may add Your own attribution
+ * notices within Derivative Works that You distribute, alongside
+ * or as an addendum to the NOTICE text from the Work, provided
+ * that such additional attribution notices cannot be construed
+ * as modifying the License.
+ *
+ * You may add Your own copyright statement to Your modifications and
+ * may provide additional or different license terms and conditions
+ * for use, reproduction, or distribution of Your modifications, or
+ * for any such Derivative Works as a whole, provided Your use,

+ * with Licensor regarding such Contributions.
+ *
+ * 6. Trademarks. This License does not grant permission to use the trade

+ *
+ * 7. Disclaimer of Warranty. Unless required by applicable law or
+ * agreed to in writing, Licensor provides the Work (and each
+ * Contributor provides its Contributions) on an "AS IS" BASIS,
+ * WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+ * implied, including, without limitation, any warranties or conditions
+ * of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+ * PARTICULAR PURPOSE. You are solely responsible for determining the
+ * appropriateness of using or redistributing the Work and assume any
+ * risks associated with Your exercise of permissions under this License.
+ *
+ * 8. Limitation of Liability. In no event and under no legal theory,
+ * whether in tort (including negligence), contract, or otherwise,
+ * unless required by applicable law (such as deliberate and grossly
+ * negligent acts) or agreed to in writing, shall any Contributor be
+ * liable to You for damages, including any direct, indirect, special,
+ * incidental, or consequential damages of any character arising as a
+ * result of this License or out of the use or inability to use the
+ * Work (including but not limited to damages for loss of goodwill,
+ * work stoppage, computer failure or malfunction, or any and all
+ * other commercial damages or losses), even if such Contributor
+ * has been advised of the possibility of such damages.
+ *
+ * 9. Accepting Warranty or Additional Liability. While redistributing
+ * the Work or Derivative Works thereof, You may choose to offer,
+ * and charge a fee for, acceptance of support, warranty, indemnity,
+ * or other liability obligations and/or rights consistent with this
+ * License. However, in accepting such obligations, You may act only
+ * on Your own behalf and on Your sole responsibility, not on behalf
+ * of any other Contributor, and only if You agree to indemnify,
+ * defend, and hold each Contributor harmless for any liability
+ * incurred by, or claims asserted against, such Contributor by reason
+ * of your accepting any such warranty or additional liability.

+ * agreed to in writing, Licensor provides the Work (and each
+ * Contributor provides its Contributions) on an "AS IS" BASIS,
+ * WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+ * implied, including, without limitation, any warranties or conditions
+ * of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+ * PARTICULAR PURPOSE. You are solely responsible for determining the
