# AGENT COSMOS (ACOS)

> ERC-721 NFT collection on BNB Smart Chain. Only wallets holding a Binance .ai Agent ID can mint. A wallet's 1st mint is free; later mints are paid in USDT (BEP-20) and 100% of mint revenue goes to a staking vault that pays USDT to stakers. Ownership of both contracts has been transferred to the dead address. Every fact below can be checked by reading the chain.

- 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

## How to mint
1. If nextMintPrice(yourWallet) > 0: on USDT 0x55d398326f99059fF775485246999027B3197955 call approve(address spender, uint256 amount) (0x095ea7b3) with spender = the NFT contract 0x3Aeda314ec05BC22E3c26a543E16Df2B8cC8fe69 and amount >= nextMintPrice.
2. On the NFT contract call mint()  selector 0x1249c58b, value 0 BNB. The contract pulls the USDT price from your wallet straight to the vault.

NFT 0x3Aeda314ec05BC22E3c26a543E16Df2B8cC8fe69:
- nextMintPrice(address) 0xbc44ecc1 -> USDT (18 decimals) for this wallet's next mint (0 = free, or wallet cap reached; check mintedByWallet)

- USDT allowance: allowance(address owner, address spender) 0xdd62ed3e on the USDT contract (spender = NFT contract)
Vault 0xaD79361E3761E337A5bbB41f4832e1FEF763B571:
- pendingOf(address) 0xf44136a1, weightOf(address) 0xdd4bc101, stakedOf(address) 0xaf500ba3
- poolBalance() 0x96365d44, totalWeight() 0x96c82e57, pendingUndistributed() 0xd3be6407, feeRecipient() 0x46904840

## Where funds go
- 100% of every paid mint goes in the same transaction from the minter to the vault (USDT transferFrom) and is shared among stakers by weight.
- The vault has no owner withdraw function. USDT 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 by tier 1-10: x0.1, x1, x1.5, x2, x3, x4, x5.5, x7, x9, x12; +5% for a wallet staking 10 or more tokens.
- New stakers only earn from the moment they stake. Revenue that arrives while nobody is staked is held and added to the next distribution.
- Claim: claim() 0x4e71d92d on the vault. A 5% claim fee goes to feeRecipient() = 0x2ecdace521320b89ae178026f5dc9e4be273eaed; the rest to the staker.

## Fees
- Mint: USDT price above plus gas. No other mint fee.
- Reward claim: 5% (constant CLAIM_FEE_BPS = 500).

## Risks
- Not audited.
- Owner is renounced: nobody can pause minting, change prices, change the fee recipient or fix anything.
- Metadata base URI is locked (metadataLocked() = true) to https://testtest111233345.longqi888666.workers.dev/meta/ . Images and metadata are served off-chain from that host.
- Rewards depend on future mints and deposits; they can be small or zero.
