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:

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

Build Status

• ✅ Core project builds successfully

• ✅ Main API projects build with 0 errors

• ✅ Solnet.Wallet package integrated

• ✅ No compilation errors in key generation code

Note: Remaining errors in full solution build are from:

• Test harness projects (missing references - expected)

• Template projects (missing Main methods - expected for templates)

• External libraries (language version issues - not related to fix)

Functional Verification

Wallet Creation Flow

1. ✅ Authentication successful

2. ✅ Wallet creation endpoint accessible

3. ✅ Solana provider type recognized (ProviderType: 3)

4. ✅ Key generation using Solnet

5. ✅ Address in correct format

6. ✅ Wallet saved successfully

7. ✅ Response contains valid wallet data

Address Validation

The generated address 5A6inmCE8ae28B5Rbhf7i7RwLAjmp3NYGuYpuoCEq7gw:

• ✅ Matches Solana address format specifications
