# CrossCurve DAO NFT

**EYWA DAO NFT** is an ERC-721 NFT created when EYWA tokens are locked in the[ **Locker**](https://docs.crosscurve.fi/user-documentation/dao/eywa-locker-interface).

**Key features:**

* **Attaching assets**: Each EYWA DAO NFT can have EYWA tokens, Vesting Safes, and other EYWA NFTs attached to it.
* **Obtaining veEYWA**: The obtained veEYWA is automatically tired to the corresponding EYWA DAO NFT.
* **Multiple ownership**: A user can own an unlimited number of EYWA DAO NFT.
* **Summation of veEYWA**: The total amount of a user’s veEYWA is equal to the sum of the veEYWA of all their EYWA DAO NFTs.

Thus, **EYWA DAO NFT** serves as a hub for managing your locked assets and voting power in the DAO, providing flexibility and scalability in project governance.

* Ownership of the Vesting Safe contract is transferred to the Locker.

1. **Vesting Safe contracts with ownership via an NFT** (Vesting Safe contracts attached to an EYWA NFT)

* The Vesting Safe is detached from an EYWA NFT and transferred to the Locker.
