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);
