Blockchain developer: Signature Edition (1-hour interactive course)

The blockchain developer job, explained by a professional in one guided hour.

In one hour you will understand how a blockchain works, what a smart contract is, how to write one in Solidity, test it, protect it from the costliest flaws and deploy it cleanly on a testnet, within the EU MiCA framework. Everything is practised with test money. No investment advice.
