-sidebarTitle: "Identity Generation"

-
-# DID Generation Patterns
-
-The Sonr project provides a robust and flexible DID (Decentralized Identifier) generation system supporting multiple key types and cryptographic methods.
-
-## Supported Key Types
-
-The `didkey.go` interface supports the following key types:
-
- RSA Public Keys
- Ed25519 Public Keys
- Secp256k1 Public Keys
-
-## Basic DID Generation
-
-### Creating a DID from a Public Key
-
-```go
-import (
-    "github.com/libp2p/go-libp2p/core/crypto"
-    "github.com/sonr-io/crypto/keys"
-)
-
-// Generate a new key pair
-privateKey, publicKey, err := crypto.GenerateKeyPair(crypto.Ed25519, -1)
-
-// Create a DID
-did, err := keys.NewDID(publicKey)
-```
-
-### Parsing an Existing DID
-
-```go
-// Parse a DID string
-did, err := keys.Parse("did:key:z6MkhaXgBZDvotDkL5257faiztiGiC2QtKLGTsyDFWYviJr4")
-```
-
-## Advanced DID Operations
-
-### Address Derivation
-
-```go
-// Get a blockchain-compatible address from a DID
-address, err := did.Address()
-```
-
-### Compressed Public Key Retrieval
-
-```go
-// Get a compressed public key (for Secp256k1)
-compressedPubKey, err := did.CompressedPubKey()
-```
-
-## MPC Enclave DID Generation
-
-For MPC (Multi-Party Computation) enclaves, use a specialized method:
-
-```go
-// Create a DID from MPC enclave public key bytes
-did, err := keys.NewFromMPCPubKey(enclavePublicKeyBytes)
-```
-
-## DID Validation
-
-```go
-// Validate a DID format
-err := keys.ValidateFormat("did:key:example123")
-```
-
-## Multicodec Support
-
-The library supports various multicodec prefixes for different key types:
-
- RSA: `0x1205`
- Ed25519: `0xed`
- Secp256k1: `0xe7`
-
-## Security Considerations
-
- Always generate keys using cryptographically secure methods
- Validate DIDs before using them in critical operations
- Use the appropriate key type for your security requirements
-
-## Example: Complete DID Workflow
-
-```go
-package main
-
-import (
-    "fmt"
-    "github.com/libp2p/go-libp2p/core/crypto"
-    "github.com/sonr-io/crypto/keys"
-)
-
-func main() {
-    // Generate a new key pair
-    privateKey, publicKey, err := crypto.GenerateKeyPair(crypto.Ed25519, -1)
-    if err != nil {
-        panic(err)
-    }
-
-    // Create a DID
-    did, err := keys.NewDID(publicKey)
-    if err != nil {
-        panic(err)
-    }
-
-    // Get the DID string
-    didString := did.String()
-    fmt.Println("Generated DID:", didString)
-
-    // Derive blockchain address
-    address, err := did.Address()
-    if err != nil {
-        panic(err)
-    }
-    fmt.Println("Blockchain Address:", address)
-}
-```
-
-## Compatibility and Interoperability
-
-The Sonr DID implementation follows the W3C DID specification, ensuring broad compatibility with other decentralized identity systems.

+
+## Architecture
+
+sonrctl is built with a clean, modular architecture:
+
+1. **Command Layer** - Handles user input and command routing
+2. **Library Layer** - Provides utilities for common operations
+3. **Storage Layer** - SQLite database for configuration persistence
+
+### Key Design Decisions
+
+- **Bun Runtime** - For blazingly fast execution and built-in tools
+- **SQLite Storage** - Lightweight, fast, and portable
+- **No External Dependencies** - Minimal deps, maximum performance
+- **Clean Separation** - Commands, libraries, and utilities are separate
+- **Type Safety** - Full TypeScript support
+
+## Docker Integration
+
+sonrctl integrates seamlessly with Docker for testnet deployment:
+
+- Start/stop docker-compose networks
+- Manage individual containers
+- Monitor container status
+- Execute commands in containers
+- View container logs
+
+The CLI can work as a drop-in replacement for manual docker-compose operations.
+
+## Development
+
+### Prerequisites
+
+- [Bun](https://bun.sh) v1.0+
+- Docker (for network operations)
+- Git
+
+### Running Locally
+
+```bash
+# Run directly with Bun
+bun run src/index.ts help
+
+# Run a specific command
+bun run src/index.ts status
+```
+
+### Adding New Commands
+
+1. Create a new file in `src/commands/`
+2. Export an async function that takes `args: string[]`
+3. Import and add to the switch statement in `src/index.ts`
+4. Update the help text
+
+Example:
+
+```typescript
+// src/commands/mycommand.ts
+export async function mycommand(args: string[]) {
+  Logger.header('My Command');
+  // Implementation
+}
+
+// src/index.ts
+import { mycommand } from './commands/mycommand';
+
+// Add to switch statement
+case 'mycommand':
+  await mycommand(commandArgs);
+  break;
+```
+
+## Examples
+
+### Setting Up a Testnet
+
+```bash
+# 1. Install the binary
+sonrctl install
+
+# 2. Start the testnet network
+sonrctl start network --detach
+
+# 3. Check status
+sonrctl status network
+
+# 4. View logs
+docker logs -f val-naruto
+
+# 5. Stop when done
+sonrctl stop network
+```
+
+### Creating a Custom Node
+
+```bash
+# 1. Initialize a custom validator
+sonrctl init validator my-validator \
+  --chain-id mychain-1 \
+  --home ~/.sonr/my-validator \
+  --rpc-port 26667
+
+# 2. Configure genesis (manual step)
+# Edit ~/.sonr/my-validator/config/genesis.json
+
+# 3. Start the node
+sonrctl start my-validator
+
+# 4. Check status
+sonrctl status my-validator
+```
+
+## Troubleshooting
+
+### Command not found
+
+```bash
+# Make sure Bun's bin directory is in your PATH
+export PATH="$HOME/.bun/bin:$PATH"
+
+# Re-link the CLI
+bun link
+```
+
+### Docker permission denied
+
+```bash
+# Add your user to the docker group
+sudo usermod -aG docker $USER
+
+# Log out and back in, or run:
+newgrp docker
+```
+
+### Binary not found after install
+
+```bash
+# Check if ~/.local/bin is in your PATH
+export PATH="$HOME/.local/bin:$PATH"
+
+# Add to your shell profile
+echo 'export PATH="$HOME/.local/bin:$PATH"' >> ~/.bashrc
+```

+# USDC Swap with DID E2E Tests
+
+Comprehensive end-to-end tests for USDC swap functionality with DID-based Interchain Accounts (ICA) on Noble testnet.
+
+## Overview
+
+This test suite validates the complete USDC swap flow including:
+- DID creation and management
+- DEX account registration via ICA
+- Cross-chain USDC swaps (SNR ↔ USDC)
+- Noble testnet IBC integration
+- Swap routing and slippage protection
+- Event verification and transaction history
+
+## Prerequisites
+
+### Network Setup
+
+1. **Sonr Testnet**: Running local testnet with DEX module enabled
+2. **Noble Testnet Connection**: IBC connection established to Noble testnet (grand-1)
+3. **IBC Relayer**: Active relayer between Sonr and Noble chains
+4. **Test Tokens**:
+   - SNR tokens for gas and swaps
+   - USDC tokens on Noble testnet (optional for full E2E)
+
+### Configuration
+
+The tests use these default configurations:
+
+```go
+// Noble Testnet
+NobleChainID     = "noble-grand-1"
+NobleConnectionID = "connection-noble"  // Update with actual connection
+NobleUSDCDenom   = "uusdc"
+
+// Test Amounts
+USDCTestAmount   = 1_000_000  // 1 USDC (6 decimals)
+SNRSwapAmount    = 1_000_000  // 1 SNR (6 decimals)
+SlippageTolerance = 0.05      // 5% slippage
+```
+
+## Test Suite Structure
+
+### Test Cases
+
+#### 01. Verify Noble Configuration
+**Purpose**: Validates Noble chain configuration and constants
+**Validates**:
+- Noble chain ID recognition
+- USDC denomination configuration
+- Decimal places (6 for USDC)
+- Chain type detection
+
+#### 02. Create DID Document
+**Purpose**: Creates a test DID for swap operations
+**Operations**:
+- Generate unique DID for test
+- Create DID document on-chain
+- Verify DID can be queried
+- Validate DID structure
+
+#### 03. Register DEX Account
+**Purpose**: Registers an ICA account on Noble connection
+**Operations**:
+- Register DEX account with Noble connection
+- Enable swap and liquidity features
+- Wait for ICA channel handshake
+- Verify account status and ICA address
+
+**Expected States**:
+- `ACCOUNT_STATUS_PENDING`: Initial state during handshake
+- `ACCOUNT_STATUS_ACTIVE`: Account ready for operations
+- `ACCOUNT_STATUS_FAILED`: Handshake failed
+
+#### 04. Execute USDC Swap (SNR → USDC)
+**Purpose**: Tests swapping SNR to USDC on Noble
+**Flow**:
+1. Setup DID and DEX account
+2. Calculate minimum output with slippage
+3. Execute swap via ICA
+4. Verify transaction success
+5. Check swap event emission
+
+**Parameters**:
+```go
+Amount:       1_000_000 usnr (1 SNR)
+MinAmountOut: 950_000 uusdc (0.95 USDC - 5% slippage)
+Timeout:      60 seconds
+```
+
+#### 05. Execute USDC Swap (USDC → SNR)
+**Purpose**: Tests reverse swap (USDC to SNR)
+**Flow**: Same as Test 04 but with reversed denoms
+
+#### 06. Swap With Invalid Parameters
+**Purpose**: Tests error handling and validation
+**Test Cases**:
+- Zero amount swap
+- Same source/target denom
+- Negative minimum output
+- Invalid connection ID
+
+**Expected**: All cases should fail gracefully
+
+#### 07. Swap With UCAN Permission
+**Purpose**: Tests UCAN-authorized delegated swaps
+**Status**: Currently skipped (requires full UCAN setup)
+**Features**:
+- UCAN token generation
+- Permission validation
+- Delegated execution
+
+#### 08. Query DEX History
+**Purpose**: Verifies transaction history tracking
+**Validates**:
+- History query endpoint
+- Activity records
+- Transaction metadata
+- Status tracking
+
+#### 09. Multiple Sequential Swaps
+**Purpose**: Tests executing multiple swaps in sequence
+**Operations**:
+- Execute 3 swaps sequentially
+- Verify each transaction succeeds
+- Check for nonce/sequence handling
+- Validate no race conditions
+
+## Running the Tests
+
+### Quick Start
+
+```bash
+# Navigate to test directory
+cd test/e2e/usdc-swap-did
+
+# Run all tests
+go test -v
+
+# Run specific test
+go test -v -run TestUSDCSwapE2E/Test04_ExecuteUSDCSwap_SNRToUSDC
+
+# Run with timeout
+go test -v -timeout 10m
+```
+
+### Prerequisites Check
+
+Before running tests, ensure:
+
+```bash
+# 1. Verify Noble connection exists
+snrd query ibc connection end connection-noble
+
+# 2. Check connection is open
+# Expected output: state: STATE_OPEN
+
+# 3. Verify ICA channel
+snrd query ibc channel channels --node tcp://localhost:26657
+
+# 4. Check DEX module is enabled
+snrd query dex params
+```
+
+### Full E2E Setup
+
+```bash
+# 1. Start Sonr testnet
+make testnet
+
+# 2. Establish Noble connection (one-time setup)
+# This requires:
+# - Noble testnet access
+# - IBC relayer configuration
+# - Channel creation
+
+# 3. Fund test accounts
+# The tests will auto-fund via faucet, but you can pre-fund:
+snrd tx bank send validator <test-address> 100000000usnr --yes
+
+# 4. Run tests
+cd test/e2e/usdc-swap-did && go test -v
+```
+
+## Test Utilities
+
+### Helper Functions
+
+#### DID Operations
+```go
+// Create test DID
+did, err := CreateTestDID(ctx, cfg, account, didID)
+
+// Query DID
+did, err := QueryDID(ctx, cfg, didID)
+```
+
+#### DEX Operations
+```go
+// Query DEX account
+account, err := QueryDEXAccount(ctx, cfg, didID, connectionID)
+
+// Query transaction history
+history, err := QueryDEXHistory(ctx, cfg, didID)
+
+// Wait for account activation
+active, err := WaitForDEXAccountActivation(ctx, cfg, didID, connectionID, timeout)
+```
+
+#### Swap Utilities
+```go
+// Validate parameters
+err := ValidateSwapParameters(sourceDenom, targetDenom, amount, minOut)
+
+// Calculate slippage
+minOut := CalculateMinimumOutput(amount, slippagePct)
+
+// Format amounts for display
+formatted := FormatUSDCAmount(1000000) // "1.000000 USDC"
+formatted = FormatSNRAmount(1000000)   // "1.000000 SNR"
+```
+
+### Assertions
+
+The test suite uses `testify/suite` and `testify/require` for assertions:
+
+```go
+// Transaction success
+require.NoError(t, err)
+require.Equal(t, uint32(0), txResp.Code)
+
+// Balance checks
+balance := s.getBalance(address, denom)
+require.True(t, balance.GT(minAmount))
+
+// Event verification
+s.verifySwapEvent(txHash, did, connectionID)
+```
+
+## Configuration
+
+### Update Connection ID
+
+Before running tests, update the Noble connection ID in `usdc_swap_test.go`:
+
+```go
+const (
+    NobleConnectionID = "connection-0"  // Replace with actual connection ID
+)
+```
+
+To find the connection ID:
+
+```bash
+# List all connections
+snrd query ibc connection connections
+
+# Look for connection to Noble (grand-1)
+# Update NobleConnectionID constant with the correct value
+```
+
+### Custom Test Configuration
+
+Create a custom config for your environment:
+
+```go
+cfg := &utils.TestConfig{
+    ChainID:        "sonrtest_1-1",
+    BaseURL:        "http://localhost:1317",
+    NobleConnection: "connection-0",  // Your Noble connection
+    // ... other settings
+}
+```
+
+## Troubleshooting
+
+### Common Issues
+
+#### 1. Connection Not Found
+```
+Error: connection connection-noble not found
+```
+**Solution**: Update `NobleConnectionID` constant with actual connection ID
+
+#### 2. ICA Account Pending
+```
+⚠ ICA address pending (channel handshake may be in progress)
+```
+**Solution**: Wait for ICA channel handshake to complete (can take 1-2 minutes)
+
+#### 3. Swap Transaction Fails
+```
+Error: DEX account not active
+```
+**Solution**: Ensure ICA account is in `ACCOUNT_STATUS_ACTIVE` state
+
+#### 4. Insufficient Funds
+```
+Error: insufficient funds
+```
+**Solution**: Fund test account with SNR tokens
+
+### Debug Mode
+
+Enable verbose logging:
+
+```bash
+# Run with verbose output
+go test -v -run TestUSDCSwapE2E 2>&1 | tee test.log
+
+# Check specific test output
+grep "Test 04" test.log
+
+# View all swap events
+grep "Swap" test.log
+```
+
+### Verify IBC Setup
+
+```bash
+# Check IBC clients
+snrd query ibc client states
+
+# Check channels
+snrd query ibc channel channels
+
+# Check connections
+snrd query ibc connection connections
+
+# Monitor relayer
+# (depends on your relayer setup)
+```

+## Future Enhancements
+
+### Planned Features
+1. **Multi-hop Swaps**: Route through multiple pools/chains
+2. **Liquidity Provision**: Add/remove liquidity tests
+3. **Limit Orders**: Create and execute limit orders
+4. **UCAN Integration**: Full delegation testing
+5. **Performance Tests**: Load testing and benchmarks
+6. **Failure Recovery**: Test ICA timeout handling
+
+### Contributing
+
+When adding new tests:
+1. Follow existing naming convention (Test##_Description)
+2. Add helper functions to `helpers.go`
+3. Update this README with new test documentation
+4. Ensure tests are idempotent
+5. Add appropriate logging for debugging

+USDC Swap E2E Tests - Implementation Notes
+
+CURRENT STATUS:
+These E2E tests are structured and ready but require manual setup steps before execution.
+
+LIMITATION:
+The test framework currently lacks full transaction signing/broadcasting capability.
+The SignAndBroadcastTx method in StarshipClient is a placeholder that requires proper
+keyring integration to function.
+
+MANUAL SETUP REQUIRED:
+Before running these tests, you must manually create the test resources using the CLI:
+
+1. Create Test DID:
+   snrd tx did create-did did:snr:test_<timestamp> --from <account> --chain-id sonrtest_1-1 --yes
+
+2. Register DEX Account:
+   snrd tx dex register-account did:snr:test_<timestamp> connection-noble \
+     --features swap,liquidity --from <account> --chain-id sonrtest_1-1 --yes
+
+3. Wait for ICA channel handshake (1-2 minutes)
+
+4. Execute Swaps:
+   snrd tx dex execute-swap did:snr:test_<timestamp> connection-noble \
+     usnr uusdc 1000000 950000 --from <account> --chain-id sonrtest_1-1 --yes
+
+ALTERNATIVE APPROACH:
+For automated E2E testing, consider:
+- Using the setup.sh script to prepare the environment
+- Implementing a test helper that shells out to the CLI
+- Integrating with cosmos-sdk/testutil for full transaction support
+- Using a dedicated test keyring with pre-configured keys
+
+See README.md for detailed setup instructions and troubleshooting.

+# Noble Testnet Integration for Sonr DEX Module
+
+## Overview
+
+This document describes the integration of the Noble testnet with Sonr's x/dex module. Noble is a Cosmos appchain purpose-built for native asset issuance, particularly USDC, in the IBC ecosystem.
+
+## What is Noble?
+
+Noble is an application-specific blockchain built on the Cosmos SDK that serves as the canonical issuance hub for USDC and other real-world assets (RWAs) in the Cosmos ecosystem. Key features:
+
+- **Native USDC Issuance**: Circle's official USDC is natively issued on Noble
+- **IBC Connectivity**: Seamlessly transfers assets across 50+ IBC-enabled chains
+- **Packet Forwarding**: Enables "1-click" asset transfers between chains
+- **CCTP Integration**: Circle's Cross-Chain Transfer Protocol for bridging from EVM chains
+
+## Noble Testnet Configuration
+
+### Chain Details
+
+- **Chain ID**: `noble-grand-1`
+- **RPC Endpoint**: `https://noble-testnet-rpc.polkachu.com:443`
+- **gRPC Endpoint**: `noble-testnet-grpc.polkachu.com:21590`
+- **USDC Denomination**: `uusdc` (micro-USDC, 6 decimals)
+
+### Default Configuration
+
+The Noble testnet is included in the default DEX module parameters:
+
+```go
+AllowedConnections: []string{
+    "noble-grand-1",  // Noble testnet - USDC hub
+    "osmo-test-5",    // Osmosis testnet
+}
+```
+
+## Integration Features
+
+### 1. USDC Helper Functions
+
+The integration includes helper functions for working with USDC:
+
+```go
+// Convert base units to USDC
+usdcAmount := ConvertToUSDC(sdk.NewInt(1500000)) // Returns 1.5 USDC
+
+// Convert USDC to base units
+baseUnits := ConvertFromUSDC(sdk.MustNewDecFromStr("1.5")) // Returns 1500000
+
+// Format for display
+formatted := FormatUSDCAmount(sdk.NewInt(1500000)) // Returns "1.500000 USDC"
+
+// Parse from string
+amount, err := ParseUSDCAmount("1.5") // Returns 1500000 base units
+```
+
+### 2. Chain Configuration
+
+```go
+// Get Noble testnet configuration
+config := GetNobleTestnetConfig()
+// Returns: NobleChainConfig{
+//     ChainID:      "noble-grand-1",
+//     RPCEndpoint:  "https://noble-testnet-rpc.polkachu.com:443",
+//     GRPCEndpoint: "noble-testnet-grpc.polkachu.com:21590",
+//     USDCDenom:    "uusdc",
+//     Decimals:     6,
+// }
+
+// Check if a chain is Noble
+isNoble := IsNobleChain("noble-grand-1") // Returns true
+```
+
+### 3. Trading Pairs
+
+Common USDC trading pairs are predefined:
+
+```go
+pairs := GetNobleUSDCPairs()
+// Returns pairs like:
+// - ATOM/USDC
+// - OSMO/USDC
+// - AKT/USDC
+// - JUNO/USDC
+// - STARS/USDC
+```
+
+### 4. Swap Parameters
+
+Structured parameters for Noble swaps:
+
+```go
+swapParams := NobleSwapParams{
+    InputDenom:  "uatom",
+    OutputDenom: "uusdc",
+    Amount:      sdk.NewInt(1000000), // 1 ATOM
+    MinOutput:   sdk.NewInt(5000000), // Min 5 USDC
+    Receiver:    "sonr1...",
+}
+
+if err := swapParams.Validate(); err != nil {
+    // Handle validation error
+}
+```
+
+### 5. Liquidity Parameters
+
+Parameters for providing liquidity:
+
+```go
+liquidityParams := NobleLiquidityParams{
+    PoolID:    "1",
+    Token0:    "uusdc",
+    Token1:    "uatom",
+    Amount0:   sdk.NewInt(1000000), // 1 USDC
+    Amount1:   sdk.NewInt(100000),  // 0.1 ATOM
+    MinShares: sdk.NewInt(1),
+}
+
+if err := liquidityParams.Validate(); err != nil {
+    // Handle validation error
+}
+```
+
+## Usage Examples
+
+### Registering a DEX Account for Noble
+
+```bash
+# Register an Interchain Account on Noble testnet
+sonrd tx dex register-dex-account \
+    did:sonr:user:abc123 \
+    connection-0 \
+    noble-grand-1 \
+    --from mykey \
+    --chain-id sonr_1-1
+```
+
+### Executing a Swap via Noble
+
+```bash
+# Swap ATOM for USDC on Noble
+sonrd tx dex execute-swap \
+    did:sonr:user:abc123 \
+    connection-0 \
+    uatom \
+    uusdc \
+    1000000 \
+    5000000 \
+    --from mykey \
+    --chain-id sonr_1-1
+```
+
+### Querying USDC Balance
+
+```bash
+# Query USDC balance on Noble for a DEX account
+sonrd query dex balance \
+    did:sonr:user:abc123 \
+    connection-0 \
+    uusdc
+```
+
+## Module Parameters
+
+The DEX module includes the following default parameters for Noble integration:
+
+```yaml
+params:
+  enabled: true
+  max_accounts_per_did: 5
+  default_timeout_seconds: 600
+  allowed_connections:
+    - noble-grand-1  # Noble testnet
+    - osmo-test-5    # Osmosis testnet
+  min_swap_amount: "1000"
+  max_daily_volume: "1000000000000"
+  rate_limits:
+    max_ops_per_block: 10
+    max_ops_per_did_per_day: 100
+    cooldown_blocks: 5
+  fees:
+    swap_fee_bps: 30      # 0.3%
+    liquidity_fee_bps: 20 # 0.2%
+    order_fee_bps: 10     # 0.1%
+    fee_collector: ""
+```
+
+## IBC Connection Setup
+
+To establish an IBC connection with Noble testnet:
+
+### 1. Create IBC Client
+
+```bash
+# Create IBC client for Noble on Sonr chain
+hermes create client \
+    --host-chain sonr_1-1 \
+    --reference-chain noble-grand-1
+```
+
+### 2. Create IBC Connection
+
+```bash
+# Create IBC connection
+hermes create connection \
+    --a-chain sonr_1-1 \
+    --b-chain noble-grand-1
+```
+
+### 3. Create Transfer Channel
+
+```bash
+# Create transfer channel
+hermes create channel \
+    --a-chain sonr_1-1 \
+    --a-connection connection-0 \
+    --a-port transfer \
+    --b-port transfer
+```
+
+### 4. Verify Connection
+
+```bash
+# Query IBC connections
+sonrd query ibc connection connections
+
+# Query IBC channels
+sonrd query ibc channel channels
+```
+
+## Security Considerations
+
+### 1. Connection Whitelisting
+
+Only connections listed in `allowed_connections` parameter can be used:
+
+```go
+func ValidateNobleConnection(connectionID string, allowedConnections []string) error {
+    for _, allowed := range allowedConnections {
+        if connectionID == allowed {
+            return nil
+        }
+    }
+    return fmt.Errorf("connection %s not in allowed connections list", connectionID)
+}
+```
+
+### 2. Rate Limiting
+
+The module implements rate limiting to prevent abuse:
+
+- **Per Block**: Maximum 10 operations per block
+- **Per DID**: Maximum 100 operations per day
+- **Cooldown**: 5 block cooldown between operations
+
+### 3. Amount Validation
+
+All amounts are validated before execution:
+
+- Minimum swap amount: 1000 base units
+- Maximum daily volume per DID: 1,000,000,000,000 base units
+- Positive amount checks on all operations
+
+### 4. UCAN Authorization
+
+All DEX operations require valid UCAN tokens:
+
+```go
+// UCAN capabilities for DEX operations
+capabilities := []string{
+    "dex/swap",
+    "dex/liquidity/provide",
+    "dex/liquidity/remove",
+    "dex/order/create",
+    "dex/order/cancel",
+}
+```
+
+## Integration Testing
+
+### Unit Tests
+
+```bash
+# Run DEX module tests
+cd x/dex
+go test -v ./...
+```
+
+### E2E Tests
+
+```bash
+# Run end-to-end tests
+cd test/e2e
+go test -v -run TestDEXModuleOperations
+```
+
+### Manual Testing
+
+1. **Start local testnet**:
+   ```bash
+   cd networks/testnet
+   docker-compose up -d
+   ```
+
+2. **Register account**:
+   ```bash
+   sonrd tx dex register-dex-account did:sonr:test connection-0 noble-grand-1 --from test
+   ```
+
+3. **Execute swap**:
+   ```bash
+   sonrd tx dex execute-swap did:sonr:test connection-0 uatom uusdc 1000000 500000 --from test
+   ```
