| ------------------ | ---------------- | ------------- | ------ |
| **Length**         | 32-44 characters | 44 characters | ✅ PASS |
| **Encoding**       | Base58           | Base58        | ✅ PASS |

### Format Comparison

**Before Fix (Bitcoin Format):**

```
76a914075e11acdb931e47156248e0bfd8f095b5a00fa488ac
```

* ❌ 50 characters (hexadecimal)
* ❌ Bitcoin P2PKH script (76a914...88ac)
* ❌ Invalid for Solana - cannot receive SOL tokens

**After Fix (Solana Format):**

```
5A6inmCE8ae28B5Rbhf7i7RwLAjmp3NYGuYpuoCEq7gw
```

* ✅ 44 characters (base58)
* ✅ Native Solana public key address
* ✅ Valid for Solana - can receive SOL tokens

***

## Implementation Details

### Changes Made

1. **Solnet.Wallet Package**
   * Added Solnet.Wallet NuGet package to Core project
   * Enables Solana-specific key generation
2. **KeyManager Updates**
   * Updated `GenerateKeyPairWithWalletAddress()` method
   * Added Solana-specific key generation using Solnet
   * Generates Ed25519 keypairs (Solana standard)
3. **KeyPairAndWallet Instantiation**
   * Fixed instantiation issue
   * Properly maps Solana keys to IKeyPairAndWallet interface

### Code Location

**File:** `OASIS Architecture/NextGenSoftware.OASIS.API.Core/Managers/KeyManager.cs`

**Method:** `GenerateKeyPairWithWalletAddress(ProviderType providerType)`

***

## Test Execution

### Test Case 1: Wallet Creation ✅ PASS

**Action:**

```bash
POST /api/Wallet/avatar/{avatarId}/create-wallet
{
  "name": "Solana Wallet - Post Fix Test",
  "description": "Testing Solnet key generation",
  "walletProviderType": 3,
  "generateKeyPair": true,
  "isDefaultWallet": false
}
```

**Result:**

* ✅ Wallet created successfully
* ✅ Address format: Solana base58 (44 characters)
* ✅ Public key matches address (Solana standard)
* ✅ No errors in response

### Test Case 2: Address Format Validation ✅ PASS

**Validation Checks:**

* ✅ Length: 44 characters (within 32-44 range)
* ✅ Encoding: Base58 (valid Solana characters)
* ✅ No Bitcoin script prefix (76a914)
* ✅ No hexadecimal format
* ✅ Valid Solana address format

### Test Case 3: Consistency ✅ PASS

**Multiple wallet creations:**

* ✅ All generated addresses are base58 format
* ✅ All addresses are 32-44 characters
* ✅ No Bitcoin format addresses generated
* ✅ Consistent format across multiple creations
