This newsletter is made possible thanks to GridPlus’s Lattice hardware wallet!
What good is a hardware wallet if you can’t be sure of what you’re signing?
The Lattice is the first and only hardware wallet that securely shows you a human readable version of an Ethereum transaction. Anything else is just security theater.
Just as importantly, the Lattice is the only hardware wallet that is built to be resistant to physical tampering.
We can’t leak your data if we don’t have it: we never store your name or address even a single day longer than we have to.
Isn’t your crypto worth securing? Buy a Lattice today.
