sure, will do

const { answer: price } = await api.call({ abi: priceFeedAbi, target: asset.priceFeed })
const totalSupply = await api.call({ abi: 'erc20:totalSupply', target: asset.assetId })
const assetDecimals = asset.decimals ?? 18
const priceDecimals = asset.priceDecimals ?? 8
const marketCap = (Number(totalSupply) / 10 ** assetDecimals) * (Number(price) / 10 ** priceDecimals)
sdk.util.sumSingleBalance(api.getBalances(), token, marketCap)
}))

return api.getBalances()
}
