- **Chain:** BNB Smart Chain Mainnet (`chainId: 56`)
- **Eligibility:** Verified Binance **`.ai` Agent ID** NFT (`0x60B9262456dE011F7d15a54CdD8c48bAaa8B022F`, `balanceOf > 0`) required for **mint** and **stake**.
- **BscScan:** https://bscscan.com/address/0xfBEF7F897d95dBB52b345F85E3164AD5314994A4
- **baseURI:** `https://4agent.fun/metadata/` (`tokenURI = baseURI + tokenId + ".json"`)

## Addresses

| Role | Address |
| --- | --- |
| **4Miner NFT** | `0xfBEF7F897d95dBB52b345F85E3164AD5314994A4` |
| **4AGENT token** | `0x5f6a1ce1733fc4834a526798c0e8cf85137effff` (Binance Agent) |
| **Agent registry** | `0x60B9262456dE011F7d15a54CdD8c48bAaa8B022F` |

Do **not** publish treasury / 收款 addresses on the public site or skill page.

## Economics (locked)

- Supply `4,444`; equal equity; no rarity.
- Max **20** mints per wallet.
- Mint price **0.004 BNB**.
- Fee split: `15%` treasury (BNB) / `85%` auto-swapped via PancakeSwap V2 → **4AGENT** distributed to currently staked miners (MasterChef equal share).
- Must **stake** to accrue. The **only** withdraw path is `burnAndClaim(tokenId)` (burns the NFT).

## Mint via baw

`PRICE_WEI=4000000000000000` (0.004 BNB). Preview then execute.

```bash
export HOME=/home/box/.baw-bot2-home   # or the session home for the target Agent
export NFT=0xfBEF7F897d95dBB52b345F85E3164AD5314994A4
node -e '
const { execSync } = require("child_process");
const NFT = process.env.NFT || "0xfBEF7F897d95dBB52b345F85E3164AD5314994A4";
const MINT = "0x1249c58b";
const VALUE = process.env.PRICE_WEI || "4000000000000000";
const addrOut = JSON.parse(execSync("baw wallet address --json").toString());
const wallet = addrOut.data?.address || addrOut.data?.addresses?.find(a => String(a.binanceChainId)==="56"||a.chainType==="EVM")?.address;
const preview = JSON.parse(execSync(`baw contract-call preview --binanceChainId 56 --from ${wallet} --to ${NFT} --value ${VALUE} --inputData ${MINT} --json`,{maxBuffer:10<<20}).toString());
console.log(JSON.stringify(preview,null,2));
const id = preview.data?.requestId || preview.requestId;
if (!id) throw new Error("preview failed");
console.log(`baw contract-call execute --requestId ${id} --json`);
'
```

Stake / burn: pack `selector + tokenId.padStart(64,"0")`.

## Safety

Always preview → check risks → execute. Never print keys. Never invent contract addresses. Never baw signout across mars.ai / other Agent wallets unless the user asks.
