CARV NFT License

CARV NFT License

1. Non-transferable ERC-721 (can be updated with governance).

2. Only syndicate funds can transfer NFT once and redistribute to their community.

3. A maximum of 100,000 tokens can be minted, with token IDs incrementing automatically.

4. Upon redemption, the token ID is permanently destroyed, and any unclaimed veCARV reverts to the foundation.

5. To redeem the NFT License, transfer the NFT to our predefined address. Redemption will be available 6 months after the TGE.
