async function myApp() {
if (!(await ever.hasProvider())) {
throw new Error('Extension is not installed');
}
const { accountInteraction } = await ever.requestPermissions({

});
if (accountInteraction == null) {
throw new Error('Insufficient permissions');
}
const selectedAddress = accountInteraction.address;
const dePoolAddress = new Address('0:bbcbf7eb4b6f1203ba2d4ff5375de30a5408a8130bf79f870efbcfd49ec164e9');
const dePool = new ever.Contract(DePoolAbi, dePoolAddress);
const transaction = await dePool
.methods

.call();
console.log(output);
} catch (e) {
if (e instanceof TvmException) {
console.error(e.code);
