Code

const fromBchAddress = 'bitcoincash:qzkrtx54agr74kxduuz3me4a2p2v7z74psgg9lkl5q'
const bitbox = new BITBOX()
const client = new GrpcClient({url: 'bchd.ny1.simpleledger.io' })
const validator = new slpjs.BchdValidator(client, console)
const bchdNetwork = new slpjs.BchdNetwork({ BITBOX: bitbox, client, validator })

async function genGroupNFT (from, fromWif) {
    const balances = await bchdNetwork.getAllSlpBalancesAndUtxos(fromBchAddress)
    console.log(`balances: ${JSON.stringify(balances, null, 2)}`)
    console.log("BCH balance:", balances.satoshis_available_bch)
}
