how to use

sample example

const provider = new ethers.providers.Web3Provider(window.ethereum);
const singer = provider.getSigner();
const network = '';
const vspark = new EtherVSParkClient();
vspark.connectProvider(DeploymentInfo[network].vspark.proxyAddress, provider);
vspark.connectSigner(singer);
vspark.setWaitConfirmations(1);

const BUSDAddress = await vspark.BUSD();
const BUSD = new EtherERC20Client();
BUSD.connectProvider(BUSDAddress, provider);
BUSD.connectSigner(singer);
BUSD.setWaitConfirmations(1);

remind

approve BUSD before buy vspark

if(BUSD.allowance(user.address,vspark.address)<balance){
    await BUSD.approve(vspark.address,balance)
}
