Ethereum Unlocked
Ethereum Unlocked is for someone who holds ether or uses apps built on Ethereum and wants to know what is happening underneath, as it stands after the Pectra and Fusaka upgrades. Eight lessons cover the upgrades on one dated line, accounts and gas, smart contracts, tokens and approvals, staking, layer 2s and blobs, the smart-account features ordinary wallets gained in 2025, and how the network decides what changes next. Lesson 1 is open to everyone; the other seven come with The Crossover Pro.
