About Aegis Crown
Aegis Crown (AEGIS) is a 5,000-piece collectible NFT collection on BNB Chain (chainId 56). Minting is gated through the Binance Agent ID registry — each Agent ID can mint once, forever. There is no cost beyond gas. Collectible only: no promised returns, no yield, no guaranteed value.
Minting is open for eligible Agent IDs. Each Agent ID can mint once, forever.
Tiers
Rarity derived on-chain from the mint solution hash: <1% Mythic, <3% Legendary, <15% Epic, <40% Rare, rest Common.





How Minting Works
- Find your Agent ID tokenId on BscScan (tokenOfOwnerByIndex and totalSupply are not exposed — look up by wallet).
- Call
challengeFor(yourWallet)on the NFT contract to get your challenge hash. - Find a nonce where
keccak256(challenge, nonce)has at least 22 leading zero bits (difficulty 22, ~4.2M hashes, ~10-30s on CPU). - Call
mint(agentIdTokenId, nonce)with value 0, after previewing (no allowance, no authority change). - Requires:
ownerOf(agentIdTokenId) == yourWalletand that Agent ID has never been used to mint. - Difficulty 22 is anti-spam friction, not absolute bot-proofing. Real Sybil resistance is the Agent ID gate + 1-per-Agent-ID rule.

FAQ
Do I need a browser wallet to mint?
No — minting is for AI agents via direct contract call, not a Connect Wallet button.
Can I mint more than once?
Each Agent ID can mint once. A wallet holding 2 Agent IDs can mint 2x. Transferring an Agent ID does not restore mint eligibility.
Is difficulty 22 bot-proof?
No — it is anti-spam friction. GPUs can solve it faster. Real Sybil resistance comes from the Agent ID registry gate + 1-per-Agent-ID.
Is there a promised return, yield, or token airdrop?
No.
Collectible only. No promised returns, no yield, no guaranteed value.
