 # `x/svc`
 
-The svc module is responsible for managing the registration and authorization of services within the Sonr ecosystem. It provides a secure and verifiable mechanism for registering and authorizing services using Decentralized Identifiers (DIDs) and now incorporates UCAN (User Controlled Authorization Networks) for enhanced authorization capabilities.
+The Service (SVC) module manages the registration and operation of decentralized services within the Sonr ecosystem. It provides a comprehensive framework for services to register with verified domains, define their permission requirements, and integrate with the broader Sonr authorization system through UCAN capabilities.
 
-## Concepts
+## Overview
 
-- **Service**: A decentralized svc on the Sonr Blockchain with properties such as ID, authority, origin, name, description, category, tags, and expiry height.
-- **Profile**: Represents a DID alias with properties like ID, subject, origin, and controller.
-- **Metadata**: Contains information about a svc, including name, description, category, icon, and tags.
-- **UCAN Authorization**: The module utilizes UCANs for a decentralized and user-centric authorization mechanism.
+The SVC module provides:

+## Core Concepts
+
+### Domain Verification
+
+Services must verify ownership of their domain through DNS TXT records before registration. This ensures that only legitimate domain owners can register services.
+
+### Service Registration
+
+Once domain ownership is verified, services can be registered with:
+
+- Unique service ID
+- Verified domain binding
+- Requested permissions (UCAN capabilities)
+- Service metadata (name, description)
+
+### Permission Model
+
+Services request specific permissions during registration, which are granted as UCAN capabilities. These permissions define what actions the service can perform on behalf of users.
+
+### Service Identity
+
+Each service has a unique identity composed of:
+
+- Service ID (chosen identifier)
+- Domain (verified TLD)
+- Owner (blockchain address)
 
 ## State
 
-The module uses the following state structures:
+### Domain Verification
 
-### Metadata
+```protobuf
+message DomainVerification {
+  string domain = 1;                 // Domain being verified
+  string owner = 2;                  // Address initiating verification
+  string token = 3;                  // Verification token
+  VerificationStatus status = 4;     // Pending, Verified, Failed
+  int64 initiated_at = 5;           // Timestamp
+  int64 expires_at = 6;             // Token expiration
+}
+```
 
-Stores information about services:
+### Service
 
-- Primary key: `id` (auto-increment)
-- Unique index: `origin`
-- Fields: id, origin, name, description, category, icon (URI), tags
-
-### Profile
-
-Stores DID alias information:
-
-- Primary key: `id`
-- Unique index: `subject,origin`
-- Fields: id, subject, origin, controller
+```protobuf
+message Service {
+  string service_id = 1;            // Unique service identifier
+  string domain = 2;                // Verified domain
+  string owner = 3;                 // Service owner address
+  string name = 4;                  // Human-readable name
+  string description = 5;           // Service description
+  repeated string permissions = 6;   // Requested permissions
+  string ucan_delegation_chain = 7; // UCAN authorization
+  int64 created_at = 8;            // Creation timestamp
+  int64 updated_at = 9;            // Last update timestamp
+}
+```

-### CLI
+## Queries
 
-(TODO: Add CLI commands for interacting with the module)
+### Domain Queries
+
+- `DomainVerification`: Check domain verification status
+
+### Service Queries
+
+- `Service`: Get a specific service by ID
+- `ServicesByOwner`: List all services owned by an address
+- `ServicesByDomain`: List all services for a domain
+
+### Module Queries
+
+- `Params`: Get module parameters
+
+## CLI Examples
+
+### Domain Verification
+
+```bash
+# Initiate domain verification
+snrd tx svc initiate-domain-verification example.com --from alice
+
+# Check verification status
+snrd query svc domain-verification example.com
+
+# The system will provide a token like: sonr-verification=abc123xyz
+# Add this as a TXT record to your domain's DNS
+
+# Verify domain after DNS propagation
+snrd tx svc verify-domain example.com --from alice
+```
+
+### Service Registration
+
+```bash
+# Register a service with basic permissions
+snrd tx svc register-service my-app example.com \
+  dwn:read,dwn:write,identity:read \
+  --from alice
+
+# Register with UCAN delegation
+snrd tx svc register-service vault-service vault.example.com \
+  vault:access,identity:read \
+  --ucan-delegation-chain="<jwt-token>" \
+  --from alice
+
+# Query service
+snrd query svc service my-app
+
+# Query services by owner
+snrd query svc services-by-owner $(snrd keys show alice -a)
+
+# Query services by domain
+snrd query svc services-by-domain example.com
+```
+
+## Integration Guide
+
+### For Service Developers
+
+1. **Domain Setup**:
+   - Register your domain with a DNS provider
+   - Ensure you have access to manage DNS TXT records
+   - Choose a unique service ID
+
+2. **Verification Process**:
+
+   ```bash
+   # Step 1: Initiate verification
+   snrd tx svc initiate-domain-verification your-domain.com --from your-key
+
+   # Step 2: Add TXT record to DNS
+   # Record: sonr-verification=<provided-token>
+
+   # Step 3: Wait for DNS propagation (usually 5-30 minutes)
+
+   # Step 4: Complete verification
+   snrd tx svc verify-domain your-domain.com --from your-key
+   ```
+
+3. **Service Registration**:
+   - Define required permissions carefully
+   - Use descriptive service names and descriptions
+   - Consider permission scope and user privacy
+
+4. **Permission Planning**:
+   Common permission patterns:
+   - `dwn:read,dwn:write` - Basic data access
+   - `identity:read` - Read user identity
+   - `vault:access` - Vault operations
+   - `credentials:verify` - Verify credentials
+
+### For Application Integrators
+
+1. **Service Discovery**:
+
+   ```bash
+   # Find services by domain
+   snrd query svc services-by-domain app.example.com
+
+   # Get service details
+   snrd query svc service service-id
+   ```
+
+2. **Permission Verification**:
+   - Check service permissions before integration
+   - Validate UCAN delegation chains
+   - Ensure permissions match your requirements
+
+3. **User Authorization Flow**:
+   - Service requests permissions from user
+   - User reviews and approves via wallet
+   - Service receives UCAN capability
+   - Service can act on user's behalf
+
+## Domain Verification Process
+
+### DNS TXT Record Format
+
+```
+sonr-verification=<token>
+```
+
+### Verification Requirements
+
+- Domain must be a valid TLD
+- DNS TXT record must match the generated token
+- Verification expires after 7 days if not completed
+- Each domain can only be verified by one owner
+
+### Example DNS Configuration
+
+```
+# For domain: app.example.com
+# Add TXT record:
+Type: TXT
+Name: @ (or app if subdomain)
+Value: sonr-verification=1234567890abcdef
+TTL: 300 (5 minutes)
+```
+
+## Security Considerations
+
+1. **Domain Ownership**: Only verified domain owners can register services
+2. **Permission Scope**: Services can only request, not grant permissions
+3. **UCAN Validation**: All capability chains are validated
+4. **Unique Domains**: Each domain can only have one owner
+5. **Service Isolation**: Services cannot access data from other services
+
+## Module Parameters
+
+- `verification_timeout`: Domain verification timeout (default: 7 days)
+- `max_services_per_owner`: Maximum services per owner (default: 100)
+- `allowed_permissions`: List of permissions services can request
+- `service_registration_fee`: Fee for service registration (default: 1000usnr)
 
 ## Events
 
-(TODO: List and describe event tags used by the module, including those related to UCAN authorization)
+The module emits the following events:
 
-## UCAN Authorization
+- `domain_verification_initiated`: When verification starts
+  - `domain`, `owner`, `token`, `expires_at`
+- `domain_verified`: When domain is successfully verified
+  - `domain`, `owner`, `verified_at`
+- `service_registered`: When a new service is registered
+  - `service_id`, `domain`, `owner`, `permissions`
+- `service_updated`: When service is updated
+  - `service_id`, `fields_updated`
 
-This module utilizes UCAN (User Controlled Authorization Networks) to provide a decentralized and user-centric authorization mechanism. UCANs are self-contained authorization tokens that allow users to delegate specific capabilities to other entities without relying on a central authority.
+## Building and Testing
 
-### UCAN Integration
+### Running Tests
 
-- The module parameters include a `UcanPermissions` field that defines the default UCAN permissions required for actions within the module.
-- Message handlers in the `MsgServer` perform UCAN authorization checks by:
-  - Retrieving the UCAN permissions from the context (injected by a middleware).
-  - Retrieving the required UCAN permissions from the module parameters.
-  - Verifying that the provided UCAN permissions satisfy the required permissions.
-- A dedicated middleware is responsible for:
-  - Parsing incoming requests for UCAN tokens.
-  - Verifying UCAN token signatures and validity.
-  - Extracting UCAN permissions.
-  - Injecting UCAN permissions into the context.
-- UCAN verification logic involves:
-  - Checking UCAN token signatures against the issuer's public key (resolved via the `x/did` module).
-  - Validating token expiration and other constraints.
-  - Parsing token capabilities and extracting relevant permissions.
+```bash
+# Run unit tests
+make -C x/svc test
 
-## Future Improvements
+# Run tests with race detection
+make -C x/svc test-race
 
-- Implement svc discovery mechanisms
-- Add support for svc reputation and rating systems
-- Enhance svc metadata with more detailed information
-- Implement svc update and deactivation functionality
+# Generate coverage report
+make -C x/svc test-cover
 
-## Tests
+# Run benchmarks
+make -C x/svc benchmark
+```
 
-(TODO: Add acceptance tests for the module)
+## Best Practices
 
-## Appendix
+### For Service Developers
 
-This module is part of the Sonr blockchain project and interacts with other modules such as DID and NFT modules to provide a comprehensive decentralized svc ecosystem.
+1. **Choose Meaningful IDs**: Use descriptive service IDs that reflect your service
+2. **Request Minimal Permissions**: Only request what you need
+3. **Document Permissions**: Clearly explain why each permission is needed
+4. **Plan for Updates**: Design your permission model for future growth
+5. **Monitor Expiration**: Keep track of UCAN expiration times
+
+### For Users
+
+1. **Verify Services**: Check domain ownership before granting permissions
+2. **Review Permissions**: Understand what each permission allows
+3. **Regular Audits**: Review granted permissions periodically
+4. **Revoke When Needed**: Remove permissions from unused services
+
+## Future Enhancements
+
+- **Service Categories**: Categorization for better discovery
+- **Reputation System**: User ratings and reviews
+- **Permission Templates**: Pre-defined permission sets
+- **Multi-sig Ownership**: Support for team-owned services
+- **Service Analytics**: Usage statistics and monitoring
+- **Subdomain Support**: Hierarchical service structures
