+# 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)
+```
+

+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.
