+  - `internal/keybase/actions_delegation.go` - Old ID-based delegation actions
+
+### UCAN v1.0.0-rc.1 Core (January 2025)
+
+The following was completed using `github.com/ucan-wg/go-ucan v1.1.0`:
+
+- ✅ Type re-exports from go-ucan (Delegation, Invocation, Command, Policy)

+
+## Deprecated Items (Removed)
+
+The following items from the previous TODO have been removed as they reference the **deprecated JWT-based UCAN format**:
+
+- ~~Section 4.1 "Token Validation" - JWT parsing~~ -> Replaced by go-ucan validation
+- ~~Section 4.2 "Capability Verification" - `can`/`with` format~~ -> Replaced by policy evaluation
+- ~~Section 4.3 "Proof Chain Validation" - JWT proof strings~~ -> Replaced by CID-based chain
+- ~~Section 3.2 "UCAN Token Actions" - Old format~~ -> Replaced by v1.0.0-rc.1 actions (4.2)
+- ~~Section 3.3 "Delegation Actions" - Old delegation model~~ -> Merged into Section 1 and 4.2
+
+The old capability model (`Attenuation`, `Resource`, `Capability` interfaces) is replaced by:
+
+- `sub` (DID) - Subject of the capability
+- `cmd` (Command) - Action being delegated
+- `pol` (Policy) - Constraints on invocation arguments

+## Quick Start
+
+### Installation
+
+```bash
+go get github.com/sonr-io/crypto/mpc
+```
+
+### Basic Usage
+
+#### Creating a New MPC Enclave
+
+```go
+package main
+
+import (
+    "fmt"
+    "github.com/sonr-io/crypto/mpc"
+)
+
+func main() {
+    // Generate a new MPC enclave with distributed keyshares
+    enclave, err := mpc.NewEnclave()
+    if err != nil {
+        panic(err)
+    }
+
+    // Get the public key
+    pubKeyHex := enclave.PubKeyHex()
+    fmt.Printf("Public Key: %s\n", pubKeyHex)
+
+    // Verify the enclave is valid
+    if enclave.IsValid() {
+        fmt.Println("✅ Enclave successfully created!")
+    }
+}
+```
+
+#### Signing and Verification
+
+```go
+// Sign data using distributed MPC protocol
+message := []byte("Hello, distributed world!")
+signature, err := enclave.Sign(message)
+if err != nil {
+    panic(err)
+}
+
+// Verify the signature
+isValid, err := enclave.Verify(message, signature)
+if err != nil {
+    panic(err)
+}
+
+fmt.Printf("Signature valid: %t\n", isValid)
+```
+
+#### Secure Export and Import
+
+```go
+// Export enclave with encryption
+secretKey := []byte("my-super-secret-key-32-bytes-long")
+encryptedData, err := enclave.Encrypt(secretKey)
+if err != nil {
+    panic(err)
+}
+
+// Import from encrypted data
+restoredEnclave, err := mpc.ImportEnclave(
+    mpc.WithEncryptedData(encryptedData, secretKey),
+)
+if err != nil {
+    panic(err)
+}
+
+fmt.Printf("Restored public key: %s\n", restoredEnclave.PubKeyHex())
+```
+
+## Core Concepts
+
+### Enclaves
+
+An **Enclave** represents a secure MPC keyshare environment that manages distributed cryptographic operations:
+
+```go
+type Enclave interface {
+    // Key Management
+    PubKeyHex() string         // Get public key as hex string
+    PubKeyBytes() []byte       // Get public key as bytes
+    IsValid() bool             // Check if enclave has valid keyshares
+    
+    // Cryptographic Operations
+    Sign(data []byte) ([]byte, error)        // Threshold signing
+    Verify(data []byte, sig []byte) (bool, error) // Signature verification
+    Refresh() (Enclave, error)               // Proactive key refresh
+    
+    // Secure Storage
+    Encrypt(key []byte) ([]byte, error)      // Export encrypted
+    Decrypt(key []byte, data []byte) ([]byte, error) // Import encrypted
+    
+    // Serialization
+    Marshal() ([]byte, error)                // JSON serialization
+    Unmarshal(data []byte) error            // JSON deserialization
+    
+    // Data Access
+    GetData() *EnclaveData                   // Access enclave internals
+    GetEnclave() Enclave                     // Self-reference
+}
+```
+
+### Multi-Party Computation Protocol
+
+The package implements a 2-of-2 threshold scheme:
+
+1. **Alice (Validator)** - Server-side keyshare
+2. **Bob (User)** - Client-side keyshare
+
+Both parties must participate in:
+- **Distributed Key Generation (DKG)** - Creates shared public key
+- **Threshold Signing** - Generates valid signatures cooperatively
+- **Key Refresh** - Rotates keyshares while preserving public key
+
+### Supported Curves
+
+The package supports multiple elliptic curves:
+
+```go
+type CurveName string
+
+const (
+    K256Name       CurveName = "secp256k1"  // Bitcoin/Ethereum
+    P256Name       CurveName = "P-256"      // NIST P-256
+    ED25519Name    CurveName = "ed25519"    // EdDSA
+    BLS12381G1Name CurveName = "BLS12381G1" // BLS12-381 G1
+    BLS12381G2Name CurveName = "BLS12381G2" // BLS12-381 G2
+    // ... more curves supported
+)
+```
+
+## Advanced Usage
+
+### Custom Import Options
+
+The package provides flexible import mechanisms:
+
+```go
+// Import from initial keyshares (after DKG)
+enclave, err := mpc.ImportEnclave(
+    mpc.WithInitialShares(validatorShare, userShare, mpc.K256Name),
+)
+
+// Import from existing enclave data
+enclave, err := mpc.ImportEnclave(
+    mpc.WithEnclaveData(enclaveData),
+)
+
+// Import from encrypted backup
+enclave, err := mpc.ImportEnclave(
+    mpc.WithEncryptedData(encryptedBytes, secretKey),
+)
+```
+
+### Key Refresh for Proactive Security
+
+```go
+// Refresh keyshares while keeping the same public key
+refreshedEnclave, err := enclave.Refresh()
+if err != nil {
+    panic(err)
+}
+
+// Public key remains the same
+fmt.Printf("Original:  %s\n", enclave.PubKeyHex())
+fmt.Printf("Refreshed: %s\n", refreshedEnclave.PubKeyHex())
+// Both should be identical!
+
+// But the enclave now has fresh keyshares
+// This provides forward secrecy against key compromise
+```
+
+### Standalone Verification
+
+```go
+// Verify signatures without the full enclave
+pubKeyBytes := enclave.PubKeyBytes()
+isValid, err := mpc.VerifyWithPubKey(pubKeyBytes, message, signature)
+if err != nil {
+    panic(err)
+}
+```
+
+### UCAN Integration
+
+The package includes MPC-based JWT signing for UCAN tokens:
+
+```go
+import "github.com/sonr-io/crypto/mpc/spec"
+
+// Create MPC-backed UCAN token source
+// (Implementation details in spec package)
+keyshareSource := spec.KeyshareSource{
+    // ... MPC enclave integration
+}
+
+// Use with UCAN token creation
+token, err := keyshareSource.NewOriginToken(
+    "did:key:audience",
+    attenuations,
+    facts,
+    notBefore,
+    expires,
+)
+```
+
+## Security Features
+
+### Encryption
+
+All encrypted operations use **AES-GCM** with **SHA3-256** key derivation:
+
+```go
+// Secure key derivation
+func GetHashKey(key []byte) []byte {
+    hash := sha3.New256()
+    hash.Write(key)
+    return hash.Sum(nil)[:32] // 256-bit key
+}
+```
+
+### Threshold Security
+
+- **2-of-2 threshold** - Both parties required for operations
+- **No single point of failure** - Neither party alone can sign
+- **Proactive refresh** - Regular keyshare rotation without changing public key
+- **Forward secrecy** - Old keyshares cannot be used after refresh
+
+### Cryptographic Primitives
+
+- **ECDSA Signing** with **SHA3-256** message hashing
+- **AES-GCM** encryption with 12-byte nonces
+- **Secure random nonce generation**
+- **Multiple curve support** for different use cases
+
+## Public API Reference

+```
+
+### EnclaveData Structure
+
+```go
+type EnclaveData struct {
+    PubHex    string    `json:"pub_hex"`   // Compressed public key (hex)
+    PubBytes  []byte    `json:"pub_bytes"` // Uncompressed public key
+    ValShare  Message   `json:"val_share"` // Alice (validator) keyshare
+    UserShare Message   `json:"user_share"`// Bob (user) keyshare
+    Nonce     []byte    `json:"nonce"`     // Encryption nonce
+    Curve     CurveName `json:"curve"`     // Elliptic curve name
+}
+```
+
+### Protocol Types
+
+```go
+type Message *protocol.Message              // MPC protocol message
+type Signature *curves.EcdsaSignature       // ECDSA signature
+type RefreshFunc interface{ protocol.Iterator } // Key refresh protocol
+type SignFunc interface{ protocol.Iterator }    // Signing protocol
+type Point curves.Point                      // Elliptic curve point
+```
+
+### Utility Functions
+
+```go
+// Cryptographic utilities
+func GetHashKey(key []byte) []byte
+func SerializeSignature(sig *curves.EcdsaSignature) ([]byte, error)
+func DeserializeSignature(sigBytes []byte) (*curves.EcdsaSignature, error)
+
+// Key conversion utilities
+func GetECDSAPoint(pubKey []byte) (*curves.EcPoint, error)
+
+// Protocol error handling
+func CheckIteratedErrors(aErr, bErr error) error
+```
+
+## Error Handling
+
+The package provides comprehensive error handling:
+
+```go
+// Common error patterns
+enclave, err := mpc.NewEnclave()
+if err != nil {
+    // Handle DKG failure
+    log.Fatalf("Failed to generate enclave: %v", err)
+}
+
+signature, err := enclave.Sign(data)
+if err != nil {
+    // Handle signing protocol failure
+    log.Fatalf("Failed to sign: %v", err)
+}
+
+// Validation errors
+if !enclave.IsValid() {
+    log.Fatal("Enclave has invalid keyshares")
+}
+```
+
+## Performance Considerations
+
+### Memory Usage
+
+- **Minimal footprint** - Only active keyshares kept in memory
+- **Efficient serialization** - JSON-based with compression
+- **Secure cleanup** - Sensitive data cleared after use
+
+### Network Communication
+
+- **Minimal rounds** - Optimized protocol with few message exchanges
+- **Small messages** - Compact protocol message format
+- **Stateless operations** - No persistent connections required
+
+### Cryptographic Performance
+

+
+### Best Practices
+
+1. **Regular key refresh** - Rotate keyshares periodically
+2. **Secure communication** - Use TLS for protocol message exchange
+3. **Access controls** - Implement proper authentication for MPC operations
+4. **Audit logging** - Log all cryptographic operations
+5. **Backup strategies** - Securely store encrypted enclave exports
+
+### Limitations
+
+- **2-of-2 threshold only** - Currently supports only 2-party protocols
+- **Network dependency** - Requires communication between parties
+- **No byzantine fault tolerance** - Assumes honest-but-curious adversaries
+
+## Contributing
+
+We welcome contributions! Please ensure:
+
+1. **Security first** - All cryptographic code must be carefully reviewed
+2. **Comprehensive testing** - Include unit tests and integration tests
+3. **Documentation** - Document all public APIs and security assumptions
+4. **Performance** - Benchmark critical cryptographic operations
+5. **Compatibility** - Maintain backward compatibility with existing enclaves
