Reading txn input data

Any transaction with data payload is meant to be addressed to a smart contract. These types of transactions usually invoke a function on smart contract.

The data payload is the hex data we see here. It is bytecode that the EVM will understand and execute. Let's breakdown the transaction data:

0xe2bbb15800000000000000000000000000000000000000000000000175150904d98ada050000000000000000000000000000000000000000000000000000000000000000

32 bytes == uint256

• 256 bits -> 64 hex characters [1 hex -> 4 bits]

• 1 byte -> 2 hex characters -> 8 bits
