What is Wei?
A wei is to ether as a satoshi is to bitcoin—both units are the smallest unit from which a user may make a transaction.
A U.S. dollar is only divisible into 100 units—pennies—and the penny is the indivisible (atomic) unit of U.S. currency.
The wei is named after Wei Dai, best known as the creator of the bitcoin predecessor "b-money" and as the developer of the Crypto++ library.
