+# DAO Registry (SOV-P0-2.3)
+
+This module implements the Phase-0 DAO Registry contract referenced by SOV-P0-2.3.
+
+Overview
+- Stores DAO metadata and addresses in a gas-efficient registry.
+- Primary storage: `HashMap<[u8;32], DAOEntry>` (dao_id -> DAOEntry).
+- Secondary index: `HashMap<[u8;32], [u8;32]>` (token_addr -> dao_id) for O(1) lookup by token address.
+
+Core functions
+- `register_dao(token_addr, class, metadata_hash, treasury, owner) -> DaoId`
+- `get_dao(token_addr) -> DAOMetadata`
+- `list_daos() -> Vec<DAOEntry>` (sorted by creation date; consider pagination for production)
+- `update_metadata(dao_id, metadata_hash)` (owner-only)
+
+Events
+- `DaoRegistered` emitted when a DAO is registered
+- `DaoUpdated` emitted when DAO metadata is updated
+
+WASM
+- `wasm.rs` exposes simple wrappers for WASM runtimes to call into the contract logic.
+
+Testing
+- Comprehensive unit tests are included in `src/contracts/dao_registry/tests.rs`.
+- A convenience script `scripts/run_dao_registry_tests.sh` runs the tests locally.
+
+Notes
+- The registry uses deterministic `dao_id` generation via blake3 over token, owner, and timestamp.
+- The contract is intentionally lightweight for Phase-0; pagination and indexed storage for large-scale registries are recommended for future improvements.
