Ethereum & EVM in SSP

Ethereum and the EVM ecosystem power most of self-custody DeFi. This SSP Academy series covers holding ETH in a 2-of-2 multisig, sending and receiving, gas fees, using one key set across Polygon, Base, and other EVM chains, account-abstraction multisig, and bridging — with the trade-offs spelled out honestly.
