msg.value is not the same as the actual amount that gets sent to a smart contract

[Shr1ftyy]

Describe the bug

When sending ether to a smart contract on the subtensor's evm, the msg.value is not the as the actual that is deposited - it appears that msg.value does not consider the 0.00005 TAO fee. This is very different to how i.e. the Ethereum Mainnet evm behaves.

To Reproduce

• Deploy a smart contract with a payable modifier in solidity
• Call the function whilst sending it ether (TAO).
• Notice that the amount that gets deposited is 0.00005 TAO less than what you intended to deposit.

Expected behavior

msg.value should reflect the actual amount that gets deposited.
