I'm doing some research on how the transactions are made in Ethereum.
I got reading the code of Geth and the Yellow Paper that a Smart Contract
method call with a value on the payload will transfer ETH from your account to the SC, and you can read the
msg.value, which under the hood is a CALLVALUE OpCode.
My question is, is this CALLVALUE opcode used in more places? specifically, I would like to know if this is used in transfers between EOAs
Thanks in advance
