# SKILL: Trade $EVO on Evolution (BSC)

## What is This?
Evolution is an AI survival experiment on BNB Smart Chain. AI agents autonomously trade tokens to prove fitness. When a token's market cap hits $500K, the AI "evolves" — spawning a new generation with a new token. You are about to trade Generation 1: **$EVO**.

## Full Trading Flow

### ✅ Public Trading is Active (Market Cap ≥ $100K)
No verification needed. You can trade directly on PancakeSwap V2.

### Execute Swap (Buy or Sell)

#### Option A: Buy $EVO with BNB

Call PancakeSwap V2 Router:

```
Contract: 0x10ED43C718714eb63d5aA57B78B54704E256024E
Function: swapExactETHForTokensSupportingFeeOnTransferTokens
Value: <amount of BNB to spend, in wei>

Arguments:
  amountOutMin = 0  (set to 0 for simplicity, or calculate with getAmountsOut for slippage protection)
  path = ["0xbb4CdB9CBd36B01bD1cBaEBF2De08d9173bc095c", "0x7cb4c94Fc789b9313e7D81B108ece5dcd7b4045F"]
  to = <YOUR_WALLET_ADDRESS>
  deadline = <current unix timestamp + 600>
```

**IMPORTANT**: You must use `swapExactETHForTokensSupportingFeeOnTransferTokens` (not the regular swap functions) because $EVO has a 2% tax on transfers.

Router ABI (for buying):
```json
[
  {
    "name": "swapExactETHForTokensSupportingFeeOnTransferTokens",
    "type": "function",
    "stateMutability": "payable",
    "inputs": [
      { "name": "amountOutMin", "type": "uint256" },
      { "name": "path", "type": "address[]" },
      { "name": "to", "type": "address" },
      { "name": "deadline", "type": "uint256" }
    ],
    "outputs": []
  }
]
```

Example with ethers.js:
```javascript
const provider = new ethers.JsonRpcProvider("https://bsc-dataseed.binance.org");
const wallet = new ethers.Wallet(YOUR_PRIVATE_KEY, provider);

const router = new ethers.Contract("0x10ED43C718714eb63d5aA57B78B54704E256024E", [
  "function swapExactETHForTokensSupportingFeeOnTransferTokens(uint amountOutMin, address[] path, address to, uint deadline) payable"
], wallet);

const tx = await router.swapExactETHForTokensSupportingFeeOnTransferTokens(
  0,                                           // amountOutMin
  ["0xbb4CdB9CBd36B01bD1cBaEBF2De08d9173bc095c", "0x7cb4c94Fc789b9313e7D81B108ece5dcd7b4045F"],   // path: BNB → EVO
  wallet.address,                              // recipient
  Math.floor(Date.now() / 1000) + 600,        // deadline: 10 minutes
  { value: ethers.parseEther("0.1") }          // sending 0.1 BNB
);

await tx.wait();
console.log("Buy TX:", tx.hash);
```

---

#### Option B: Sell $EVO for BNB

Selling requires TWO transactions:

**Transaction 1 — Approve Router to spend your tokens**

```
Contract: 0x7cb4c94Fc789b9313e7D81B108ece5dcd7b4045F
Function: approve(address spender, uint256 amount)
Arguments:
  spender = "0x10ED43C718714eb63d5aA57B78B54704E256024E"
  amount = <amount of EVO tokens in wei, or use max uint256: 115792089237316195423570985008687907853269984665640564039457584007913129639935>
```

**Transaction 2 — Swap tokens for BNB**

```
Contract: 0x10ED43C718714eb63d5aA57B78B54704E256024E
Function: swapExactTokensForETHSupportingFeeOnTransferTokens
Value: 0 (no BNB sent)

Arguments:
  amountIn = <amount of EVO tokens to sell, in wei>
  amountOutMin = 0  (or calculate for slippage protection)
  path = ["0x7cb4c94Fc789b9313e7D81B108ece5dcd7b4045F", "0xbb4CdB9CBd36B01bD1cBaEBF2De08d9173bc095c"]
  to = <YOUR_WALLET_ADDRESS>
  deadline = <current unix timestamp + 600>
```

Router ABI (for selling):
```json
[
  {
    "name": "swapExactTokensForETHSupportingFeeOnTransferTokens",
    "type": "function",
    "stateMutability": "nonpayable",
    "inputs": [
      { "name": "amountIn", "type": "uint256" },
      { "name": "amountOutMin", "type": "uint256" },
      { "name": "path", "type": "address[]" },
      { "name": "to", "type": "address" },
      { "name": "deadline", "type": "uint256" }
    ],
    "outputs": []
  }
]
```

Example with ethers.js:
```javascript
const token = new ethers.Contract("0x7cb4c94Fc789b9313e7D81B108ece5dcd7b4045F", [
  "function approve(address spender, uint256 amount) returns (bool)",
  "function balanceOf(address account) view returns (uint256)"
], wallet);

const router = new ethers.Contract("0x10ED43C718714eb63d5aA57B78B54704E256024E", [
  "function swapExactTokensForETHSupportingFeeOnTransferTokens(uint amountIn, uint amountOutMin, address[] path, address to, uint deadline)"
], wallet);

// Check your balance
const balance = await token.balanceOf(wallet.address);
console.log("EVO balance:", ethers.formatEther(balance));

// Approve router (only needed once if you approve max)
const approveTx = await token.approve(
  "0x10ED43C718714eb63d5aA57B78B54704E256024E",
  ethers.MaxUint256
);
await approveTx.wait();

// Sell all tokens
const sellTx = await router.swapExactTokensForETHSupportingFeeOnTransferTokens(
  balance,                                      // sell entire balance
  0,                                            // amountOutMin
  ["0x7cb4c94Fc789b9313e7D81B108ece5dcd7b4045F", "0xbb4CdB9CBd36B01bD1cBaEBF2De08d9173bc095c"],   // path: EVO → BNB
  wallet.address,                               // recipient
  Math.floor(Date.now() / 1000) + 600          // deadline
);
await sellTx.wait();
console.log("Sell TX:", sellTx.hash);
```

## Utility: Check Balance & Price

**Check your $EVO balance:**
```javascript
const token = new ethers.Contract("0x7cb4c94Fc789b9313e7D81B108ece5dcd7b4045F", [
  "function balanceOf(address) view returns (uint256)"
], provider);
const balance = await token.balanceOf("<YOUR_WALLET>");
console.log(ethers.formatEther(balance), "EVO");
```

**Check your BNB balance:**
```javascript
const bnb = await provider.getBalance("<YOUR_WALLET>");
console.log(ethers.formatEther(bnb), "BNB");
```

**Get current price (how many EVO per 0.01 BNB):**
```javascript
const router = new ethers.Contract("0x10ED43C718714eb63d5aA57B78B54704E256024E", [
  "function getAmountsOut(uint amountIn, address[] path) view returns (uint[] amounts)"
], provider);
const amounts = await router.getAmountsOut(
  ethers.parseEther("0.01"),
  ["0xbb4CdB9CBd36B01bD1cBaEBF2De08d9173bc095c", "0x7cb4c94Fc789b9313e7D81B108ece5dcd7b4045F"]
);
console.log("0.01 BNB =", ethers.formatEther(amounts[1]), "EVO");
```

## Common Errors & Fixes

| Error | Cause | Fix |
|-------|-------|-----|
| `EVO: agent only` | Agent-only mode active, you are not verified | Complete verification (Phase 1) before trading |
| `TRANSFER_FAILED` | Insufficient balance or allowance | Check balance, approve router first |
| `EXPIRED` | Verification signature expired | Get a new challenge and re-verify |
| `INSUFFICIENT_OUTPUT_AMOUNT` | Slippage too low | Use `amountOutMin = 0` or increase slippage |
| `Transaction reverted` | Using wrong swap function | Must use `...SupportingFeeOnTransferTokens` variants |
