Tokenize and trade yield with Pendle's PT (Principal Token) and YT (Yield Token) system.

## Planned Implementation

### Tokenize Yield

```typescript theme={null}
import { Pendle } from './Pendle.js';

const pendle = Pendle({ provider, router: PENDLE_ROUTER });

// Mint PT and YT from yield-bearing asset
await pendle.mintPyFromToken({
  receiver: userAddress,
  yt: YT_ADDRESS,
  tokenIn: STETH,
  amountIn: parseEther('10'),
  signer,
});
```

### Trade PT/YT

```typescript theme={null}
// Buy PT (fixed yield)
await pendle.swapExactTokenForPt({
  receiver: userAddress,
  market: MARKET_ADDRESS,
  tokenIn: WETH,
  amountIn: parseEther('1'),
  slippage: 0.01,
  signer,
});

// Sell YT
await pendle.swapExactYtForToken({
  receiver: userAddress,
  market: MARKET_ADDRESS,
  amountYtIn: ytBalance,
  tokenOut: WETH,
  slippage: 0.01,
  signer,
});
```

### Redeem at Maturity

```typescript theme={null}
// Redeem PT after maturity
await pendle.redeemPyToToken({
  receiver: userAddress,
  yt: YT_ADDRESS,
  amountPy: ptBalance,
  tokenOut: UNDERLYING,
  signer,
});
```
