### Buy example
```typescript
import { Wallet } from 'ethers';
import { JsonRpcProvider } from 'ethers';
import { Moonshot, Token, FixedSide, Environment } from '@wen-moon-ser/moonshot-sdk-evm';
export const buyTx = async (): Promise => {
console.log('--- Buying token example ---');
const rpcUrl = 'https://base-sepolia.gateway.tenderly.co';
const provider = new JsonRpcProvider(rpcUrl);
const signer = new Wallet('private key', provider);
const moonshot = new Moonshot({
signer: signer,
env: Environment.TESTNET,
});
const token = await Token.create({
tokenAddress: '0x1234567890123456789012345678901234567890',
moonshot,
});
const tokenAmount = 10000n * 10n ** 18n; // Buy 10k tokens
const collateralAmount = await token.getCollateralAmountByTokens({
tokenAmount,
tradeDirection: 'BUY',
});
const tx = await token.prepareTx({
slippageBps: 500,
tokenAmount,
collateralAmount,
tradeDirection: 'BUY',
fixedSide: FixedSide.OUT,
});
tx.from = await signer.getAddress();
const gas = await provider.estimateGas(tx);
const feeData = await provider.getFeeData();
tx.gasLimit = gas;
tx.gasPrice = feeData.gasPrice!;
const txHash = await signer.sendTransaction(tx);
console.log('Transaction hash:', txHash);
};
```
