+Add CIP-30 message signing support with modular architecture
+
+This release introduces comprehensive CIP-30 `signData` and `verifyData` support, implementing the complete COSE Sign1 specification with a clean, modular structure:
+
+**New Features:**
+- Full CIP-30 message signing (`signData`) and verification (`verifyData`) implementation
+- COSE (CBOR Object Signing and Encryption) primitives per RFC 8152
+- Support for Ed25519 signatures with proper COSE key structures
+- Message hashing with BLAKE2b-256 for payload integrity
+- CIP-8 compliant address field handling
+- Complete test coverage with CSL compatibility tests
+
+**Module Structure:**
+- `message-signing/SignData.ts` - Main CIP-30 signData/verifyData API
+- `message-signing/Header.ts` - COSE header structures and operations
+- `message-signing/Label.ts` - COSE label types and algorithm identifiers
+- `message-signing/CoseSign1.ts` - COSE_Sign1 structure implementation
+- `message-signing/CoseKey.ts` - COSE key format support
+- `message-signing/Ed25519Key.ts` - Ed25519 key operations
+- `message-signing/Utils.ts` - Encoding and conversion utilities
+
+**Breaking Changes:**
+- Refactored `Bytes` module API:
+  - Renamed `bytesEquals` to `equals` with stricter type signature (no longer accepts undefined)
+  - Removed `Bytes.FromHex` schema in favor of Effect's built-in `Schema.Uint8ArrayFromHex`
+  - Updated `fromHex`/`toHex` to use Effect's native schemas
+
+**Internal Improvements:**
+- Removed unused `Bytes` imports across 32 files
+- Updated all modules to use new Bytes API
+- Improved CBOR encoding/decoding with proper codec options
+- Enhanced type safety with Effect Schema compositions
