Bluwhale NFT License

Bluwhale NFT License

• Non-transferable ERC-721 for first year (can be updated with governance).

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

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

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

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