- Only wallets holding a Binance .ai Agent ID. Checked on-chain on every mint: the NFT contract calls balanceOf(address) (0x70a08231) on 0x60B9262456dE011F7d15a54CdD8c48bAaa8B022F and reverts with "NO_AGENT_ID" if it is 0.
- Buying on the secondary market is not restricted.

## Supply, price and limits
- Max supply 4,444. Max 5 mints per wallet.
- Free mints: 444 in total, first come first served, only as a wallet's 1st token. All 444 have been used (freeRemaining() returned 0 on 2026-11-05).

## How to mint (send to the NFT contract)

- Eligibility: balanceOf(address) 0x70a08231 on the Agent ID registry 0x60B9262456dE011F7d15a54CdD8c48bAaa8B022F (> 0 = eligible)
Vault 0x6F56112780Ebac9173724bdc48BA5D828a9Fcf43:
- pendingOf(address) 0xf44136a1, weightOf(address) 0xdd4bc101, stakedOf(address) 0xaf500ba3
- poolBalance() 0x96365d44, totalWeight() 0x96c82e57, pendingUndistributed() 0xd3be6407

## Where funds go
- 100% of every paid mint is forwarded in the same transaction to the vault (onMintRevenue) and shared among stakers by weight.
- The vault has no owner withdraw function. BNB leaves the vault only when stakers call claim().
- Staking: stake(uint256[] ids) 0x0fbf0a93, unstake(uint256[] ids) 0xe449f341 on the vault. Staked NFTs stay in the owner's wallet but cannot be transferred while staked.
- Weights: tier 1 x0.1, tier 2 x1, tier 3 x2.5, tier 4 x5, tier 5 x10; +5% for a wallet staking 5 or more tokens.
- New stakers only earn from the moment they stake. Revenue that arrives while nobody is staked is held and released to stakers later.
- Claim: claim() 0x4e71d92d on the vault. A fixed 10% claim fee goes to feeRecipient(); the rest to the staker.

## Fees
- Mint: price above plus gas. No other mint fee.
- Reward claim: 10% (constant CLAIM_FEE_BPS = 1000).

## Admin powers and risks
- Not audited.
- Owner of both contracts: 0xb7a6b12fa8b70f02b53521e30f7f361e60092f84 (deployer). The owner can open or close minting, change the metadata base URI (metadata is not locked), change the vault's feeRecipient (currently the same deployer address), and transfer ownership. The owner cannot withdraw vault funds, change prices, change the 10% fee, or change the vault address once set.
- Rewards depend on future mints and deposits; they can be small or zero.
