+
+The Decentralized Exchange (DEX) module provides cross-chain trading capabilities through IBC Interchain Accounts (ICA), enabling users to perform swaps, manage liquidity, and execute orders on remote DEX chains while maintaining custody through their Sonr DID. This module bridges the gap between self-sovereign identity and DeFi operations across the Cosmos ecosystem.
+
+## Overview
+
+The DEX module provides:
+
+- **Cross-Chain Trading**: Execute swaps on remote DEX chains via ICA
+- **Liquidity Management**: Add and remove liquidity from pools across chains
+- **Order Management**: Create and manage limit orders on compatible DEXs
+- **DID-Controlled Accounts**: All operations authorized through Sonr DIDs
+- **UCAN Authorization**: Fine-grained permissions for trading operations
+- **Multi-DEX Support**: Connect to multiple DEX chains simultaneously
+- **Rate Limiting**: Protection against spam and excessive operations
+- **Activity Tracking**: Complete history of all DEX operations
+
+## Core Concepts
+
+### Interchain Accounts (ICA)
+
+The module leverages IBC's Interchain Accounts to create controlled accounts on remote DEX chains. Each account is linked to a Sonr DID and managed through ICA transactions.
+
+### DID-Based Authorization
+
+All DEX operations require authorization from a valid Sonr DID, ensuring that only authenticated users can perform trading operations.
+
+### UCAN Tokens
+
+User-Controlled Authorization Network (UCAN) tokens provide delegated authority for specific operations, enabling secure third-party integrations.
+
+### Cross-Chain Liquidity
+
+Users can provide liquidity to pools on any supported DEX chain while maintaining custody through their Sonr identity.
+
+## State
+
+### Interchain DEX Accounts

+```protobuf
+message InterchainDEXAccount {
+  string did = 1;                                    // DID controller of this account
+  string connection_id = 2;                         // IBC connection to the remote chain
+  string host_chain_id = 3;                         // Remote chain ID (e.g., osmosis-1)

+
+## Integration Guide
+
+### For DApp Developers
+
+1. **Account Setup**: Register ICA accounts for target DEX chains
+2. **Permission Management**: Issue UCAN tokens for specific operations
+3. **Execute Trades**: Use the module's messages to perform DEX operations
+4. **Monitor Activity**: Subscribe to events for real-time updates
+5. **Query State**: Use queries to display balances and history
+
+### For DEX Integration
+
+1. **IBC Connection**: Establish IBC connection to Sonr
+2. **ICA Support**: Ensure ICA host module is enabled
+3. **Message Handling**: Support standard Cosmos SDK messages
+4. **Event Emission**: Emit appropriate events for tracking
+
+### For Wallet Developers
+
+1. **DID Integration**: Support Sonr DID authentication
+2. **UCAN Generation**: Implement UCAN token creation
+3. **Transaction Building**: Build DEX module transactions
+4. **History Display**: Query and display DEX activity
+
+## Technical Architecture
+
+### ICA Message Flow
+
+1. **Message Creation**: User creates DEX operation message
+2. **DID Verification**: Module verifies DID ownership
+3. **UCAN Validation**: Validates authorization token
+4. **ICA Packet**: Constructs ICA packet for remote chain
+5. **IBC Relay**: Packet sent via IBC to target chain
+6. **Remote Execution**: Operation executed on DEX chain
+7. **Acknowledgment**: Result returned via IBC
+8. **Event Emission**: Events emitted for tracking
+
+### Rate Limiting System
+
+The module implements multi-layer rate limiting:
+
+```go
+// Per-block rate limiting
+if opsThisBlock >= params.RateLimits.MaxOpsPerBlock {
+    return errorsmod.Wrap(ErrRateLimited, "max operations per block exceeded")
+}
+
+// Per-DID daily rate limiting
+if opsToday >= params.RateLimits.MaxOpsPerDidPerDay {
+    return errorsmod.Wrap(ErrRateLimited, "daily operation limit exceeded")
+}
+
+// Cooldown period enforcement
+if blocksSinceLastOp < params.RateLimits.CooldownBlocks {
+    return errorsmod.Wrap(ErrCooldown, "operation cooldown period active")
+}
+```
+
+### Fee Collection
+
+Platform fees are collected on successful operations:
+
+```go
+// Calculate platform fee
+fee := amount.Mul(params.Fees.SwapFeeBps).Quo(10000)
+
+// Transfer fee to collector
+err := bankKeeper.SendCoins(ctx, userAddr, feeCollector, fee)
+```
+
+## Security Considerations
+
+1. **DID Authentication**: All operations require valid DID signatures
+2. **UCAN Authorization**: Fine-grained permissions prevent unauthorized operations
+3. **Rate Limiting**: Protects against spam and DoS attacks
+4. **Slippage Protection**: Minimum output amounts prevent sandwich attacks
+5. **Timeout Enforcement**: Operations expire to prevent stale execution
+6. **Connection Whitelisting**: Only approved IBC connections allowed
+7. **Volume Limits**: Daily volume caps prevent excessive exposure
+8. **ICA Security**: Leverages IBC's security guarantees
+9. **Event Auditing**: Comprehensive event trail for all operations
+10. **Fee Mechanisms**: Platform fees discourage spam
+
+## Performance Optimization
+
+### Batch Operations
+
+The module supports batching for improved efficiency:
+- Multiple swaps in single ICA packet
+- Bulk order creation/cancellation
+- Aggregated liquidity operations
+
+### Caching Strategy
+
+- Account data cached for quick lookups
+- Pool information cached with TTL
+- Order book snapshots for fast queries
+
+### Query Optimization
+
+- Indexed by DID for fast account lookups
+- Pagination for large result sets
+- Filtered queries for specific operations
+
+## Supported DEX Chains
+
+### Currently Supported
+
+- **Osmosis**: Full swap, liquidity, and order support
