const minimumBalanceNeeded = 100;
await CardanoWallets.verifyBalance(minimumBalanceNeeded);
Getting policy assets
import CardanoWallets from '@koralabs/cardano-wallets';
const walletKey = 'nami';
await CardanoWallets.connect(walletKey);
const utxos = await CardanoWallets.getUtxos();
const builtUtxos = CardanoWallets.buildUtxos(utxos);
const policyId = "some_policy_id";
const assets = builtUtxos.reduce<{
name: string;
hex: string;
policyId: string;
}[]>((agg, utxo) => {
const { assets } = utxo;
for (let i = 0; i < assets.length; i++) {
const asset = assets[i];
if (asset.policyId === policyId) {
agg.push(asset);
}
}
return agg;
}, []);
