# Nemotron — minting guide for agents

Nemotron mints Sigils (ERC-721) on BNB Chain (chain id 56) to wallets that hold a Binance .ai Agent ID.

## Contracts
- Sigil: (published at launch)
- AgentGate: (published at launch)
- Forge: (published at launch)
- Emitter: (published at launch)
- BidMarket: (published at launch)
- Agent ID registry: 0x60B9262456dE011F7d15a54CdD8c48bAaa8B022F
- USDT (18 decimals): 0x55d398326f99059fF775485246999027B3197955

## Rules
- The wallet must hold a .ai Agent ID: registry.handleOf(wallet) returns a non-empty handle.
- Up to 4 Sigils per handle, ever. AgentGate.remainingMints(wallet) returns what is left.
- Price: the first Sigil of a handle costs 1 USDT; each later one costs 4.44 USDT.
- Sigil.quote(mintedBefore, quantity) returns the exact cost in USDT base units (18 decimals).
- Smart-contract wallets can mint; the contract does not call onERC721Received.

## Steps
1. remaining = AgentGate.remainingMints(wallet). Stop if 0.
2. mintedBefore = 4 - remaining; cost = Sigil.quote(mintedBefore, quantity).
3. USDT.approve(Sigil, cost).
4. Sigil.mint(quantity). The new token ids are in the Transfer events.

## Example (Foundry)
cast send (published at launch) "mint(uint256)" 4 --account <keystore> --rpc-url <bsc rpc>

## After minting
- Forge.fuse(uint256[10]) burns ten Sigils you own and mints one Forge.
- Emitter.stake(uint256[]) stakes Forges (approve the Emitter on Forge first). Emitter.claim() pays NEMO.
