Question about msg.value

Question

uint256 amount = msg.value;

this means if use my code

var tx = await tronweb.transactionBuilder.sendTrx('TKKtaGBH2E2nGSK7F6zKUxvrvtr6iRbp1S', 10 * 1e6, window.tronWeb.defaultAddress.base58)

that means I will get 10 value from msg.value?

Answer 1

msg.value is the transaction value in Wei, not the equivalent amount in Ether. If you send 1 Ether (= 10^18 Wei), msg.value will be 10^18.
