## WEB3-ETH-IBAN Implementation
|
|
|
|
### ✅ Complete Implementation
|
|
|
|
**Location**: `api/services/mapping-service/src/services/providers/web3-provider.ts`
|
|
|
|
**Features**:
|
|
- ✅ `addressToIBAN()` - Convert Ethereum address to IBAN
|
|
- ✅ `ibanToAddress()` - Convert IBAN to Ethereum address
|
|
- ✅ MOD-97-10 check digit calculation
|
|
- ✅ Base36 encoding/decoding
|
|
- ✅ Address validation and checksum normalization
|
|
- ✅ IBAN format validation
|
|
|
|
**Format**:
|
|
- IBAN: `XE` + 2 check digits + 30 alphanumeric (34 total)
|
|
- Based on EIP-681 and ISO 13616
|
|
|
|
**Endpoints**:
|
|
- `POST /v1/mappings/web3/address-to-iban`
|
|
- `POST /v1/mappings/web3/iban-to-address`
|
|
- `POST /v1/mappings/web3/validate-iban`
|
|
- `POST /v1/mappings/web3/validate-address`
|
|
|
|
## Architecture
|
|
|
|
### Service Independence
|
|
- ✅ Each service independently deployable
|
|
- ✅ Own Express server
|
|
- ✅ Own storage layer (in-memory, DB-ready)
|
|
- ✅ HTTP integration with main REST API
|
|
- ✅ Event bus integration
|
|
|
|
### Storage Layer
|
|
- ✅ Interface-based abstraction
|
|
- ✅ In-memory implementation
|
|
- ✅ Database-ready structure
|
|
- ✅ Easy migration path
|
|
|
|
### HTTP Integration
|
|
- ✅ Axios-based HTTP clients
|
|
- ✅ Configuration via environment variables
|
|
- ✅ Error handling and retries
|
|
- ✅ Request/response logging
|
|
|
|
### Event Publishing
|
|
- ✅ Standard event envelope format
|
|
- ✅ Correlation ID tracking
|
|
- ✅ Event bus client integration
|
|
|
|
## Dependencies
|
|
|
|
### Added Dependencies
|
|
- `uuid` - UUID generation (all services)
|
|
- `axios` - HTTP client (all services)
|
|
- `xml2js` - XML parsing (orchestrator)
|
|
- `js-yaml` - YAML parsing (orchestrator)
|
|
- `ethers` - Ethereum utilities (mapping-service)
|
|
|
|
## File Count
|
|
|
|
- **Total TypeScript files**: 40+ across all microservices
|
|
- **Services**: 4 complete services
|
|
- **Routes**: All routes implemented
|
|
- **Storage**: All storage layers implemented
|
|
- **HTTP Clients**: All HTTP clients implemented
|
|
|
|
## Error Handling
|
|
|
|
All `throw new Error()` statements are proper error handling (not "Not implemented"):
|
|
- ✅ Input validation errors
|
|
- ✅ Not found errors
|
|
- ✅ Invalid state transition errors
|
|
- ✅ Business logic errors
|
|
|
|
## Documentation
|
|
|
|
- ✅ README files for each service
|
|
- ✅ API endpoint documentation
|
|
- ✅ Configuration documentation
|
|
- ✅ WEB3-ETH-IBAN usage examples
|
|
|
|
## Next Steps (Optional)
|
|
|
|
1. Database migration (replace in-memory stores)
|
|
2. Rail API integration (actual Fedwire/SWIFT/SEPA/RTGS APIs)
|
|
3. Provider SDK integration (actual WalletConnect/Fireblocks SDKs)
|
|
4. AS4 gateway integration
|
|
5. Event bus infrastructure (Kafka/NATS)
|
|
6. Enhanced testing
|
|
7. Monitoring and metrics
|
|
|
|
