# Cosmos SDK Integration

> Cosmos SDK modules and custom MANTRA modules

## Core Cosmos SDK Modules

MANTRA Chain uses standard Cosmos SDK modules:

* **Auth Module**: Account management and authentication
* **Bank Module**: Token transfers and balances
* **Staking Module**: Validator staking and delegation
* **Distribution Module**: Fee and reward distribution
* **Slashing Module**: Validator penalties
* **Gov Module**: On-chain governance
* **IBC Module**: Inter-Blockchain Communication
* **Custom Modules**: MANTRA-specific modules for RWA functionality

## Custom MANTRA Modules

### ERC20 Module

* ERC-20 token support
* TokenFactory integration
* EVM compatibility

## Module Interactions

All modules interact through the Cosmos SDK's message routing system, allowing:

* Cross-module transactions
* Atomic operations
* State consistency

## Next Steps
