ABI Encoding: Learn To Construct Calldata By Hand

Learn how to construct calldata by hand, as well as how to initiate contract calls using this data – including interactions between contracts themselves. Mastery of this skill will allow you to call any contract on the blockchain with any calldata you want.

This video is a workshop addition to my previous video on ABI encoding and decoding:    • Mastering ABI Encoding for Solidity a...
