    • Authentication requirements

  • README.md updated:

    • Wallet architecture section added
    • Documentation links added

Acceptance Criteria Verification

✅ Each new campaign triggers a unique Stellar account setup

Verification Steps:

  1. Start backend server
  2. Create new campaign via API
  3. Verify wallet_public_key is unique
  4. Verify wallet_secret_encrypted is stored
  5. Check Stellar account exists on-chain
  6. Verify multisig configuration (2 signers, threshold 2)
  7. Verify USDC trustline established

Expected Results:

  • Campaign record has unique wallet_public_key
  • Encrypted secret stored in database
  • On-chain account has correct multisig setup
  • USDC trustline present

✅ Developers have step-by-step documentation for wallet creation

Verification Steps:

  1. Read WALLET_ARCHITECTURE.md
  2. Follow "Phase 1: Campaign Creation" section
  3. Verify all steps are clear and actionable
  4. Check API reference examples work
  5. Verify code snippets are correct

Expected Results:

  • Documentation is comprehensive and clear
  • All code examples are accurate
  • API endpoints are documented with examples
  • Troubleshooting section covers common issues

✅ Fund flows and account controls are fully auditable

Verification Steps:

  1. Create test campaign
  2. Send test contribution
  3. Call GET /api/wallets/:campaignId/transactions
  4. Call GET /api/wallets/:campaignId/payments
  5. Verify transaction appears in both endpoints
  6. Check on-chain via Stellar Horizon
  7. Verify database contributions table

Expected Results:

  • Transaction history endpoint returns all transactions
  • Payment history endpoint returns all payments
  • Data matches on-chain records
  • Database audit trail is complete

Testing Checklist

Unit Tests

  • Test encryptSecret() and decryptSecret()
  • Test encryption with different key lengths
  • Test decryption with wrong key (should fail)
  • Test recoverWalletFromSecret()
  • Test wallet recovery with invalid secret

Integration Tests

  • Test campaign creation with wallet encryption
  • Test wallet config endpoint
  • Test transaction history endpoint
  • Test payment history endpoint
  • Test wallet recovery endpoint
  • Test unauthorized access (non-creator)
  • Test missing encryption key error handling

End-to-End Tests

  • Complete campaign creation flow
  • Complete contribution flow
  • Complete withdrawal flow
  • Complete wallet recovery flow
  • Verify on-chain state matches database

Security Tests

  • Verify encrypted secrets cannot be decrypted without key
  • Verify non-creators cannot access wallet endpoints
  • Verify wallet recovery requires authentication
  • Verify private keys never appear in logs
  • Verify private keys never appear in API responses
