2. Senators call on Facebook to shelve Novi

Also on Tuesday, Senate Democrats wrote a letter to Mark Zuckerberg, CEO of Facebook, in an effort to push the social media giant to end its digital wallet project, Novi.

The letter, which was written by Sens. Brian Schatz, D-HI.; Sherrod Brown, D-Ohio.; Elizabeth Warren, D-Mass.; and others, came after Facebook launched its Novi pilot program in the U.S. and Guatemala on Tuesday.

“Facebook cannot be trusted to manage a payment system or digital currency when its existing ability to manage risks and keep consumers safe has proven wholly insufficient,” the letter read. “We urge you to immediately discontinue your Novi pilot and to commit that you will not bring Diem to market.”

Diem, rebranded from Libra, is Facebook’s halted digital currency project. But, rather than use Diem, Facebook announced it plans to use a stablecoin called the Paxos Dollar. Novi would let users send and receive money using the Paxos Dollar, with Coinbase as its custody partner.

3. Worldcoin scans people’s eyes in exchange for free cryptocurrency

Silicon Valley tech millionaire Sam Altman launched a new start-up called Worldcoin, which claims it will give free cryptocurrency to those who verify their accounts by taking an iris scan.

Worldcoin says it has shipped its scanning devices to people in 12 countries.

Once users sign up by having their iris scanned, the image is encrypted and becomes a unique code, while the original data is deleted to protect users’ privacy, Worldcoin told CNBC. Then, users are given Worldcoin’s cryptocurrency for free.

Worldcoin has amassed over 100,000 users globally and is onboarding 700 more each week. The start-up aims to hit 1 billion users by 2023.

4. Robinhood’s crypto wallet waitlist tops 1 million customers

During CNBC’s Disruptor 50 summit on Thursday, Robinhood CEO Vlad Tenev said that the waitlist for the trading app’s crypto wallet has more than 1 million customers.

“You can have a wallet, you can send people cryptocurrencies from that wallet to their wallet,” Tenev said. “There’s certain advantages that are in the technology that make it kind of global and accessible by default and that makes it very interesting.”

Last month, Robinhood announced it was testing a wallet feature that will allow investors to trade, send and receive cryptocurrencies. Users will also be able to move cryptocurrencies in and out of the Robinhood app.
