Aztec ($AZTEC) Login to HTX. This time, the $AZTEC is a "Holy Grail" project in the Ethereum privacy track. This is not just privacy; it's the era of "dark contracts." Aztec is not like Tornado Cash, which is simply a mixer; its killer feature is the "public-private hybrid state." What does this mean? You can run smart contracts on Ethereum L2, but the logic and data of these contracts are encrypted. This directly facilitates institutional entry.
