☠️ Oracle Pyth Goes Haywire on Solana with Bad Prices

BREAKDOWN The Pyth Network malfunctioned on Sep. 20 as the data provider reported a Bitcoin price of $5,402 on a day when other sources like CoinGecko didn’t report a BTC price below $40K.

DISPARITY That wasn’t the only snafu. Pyth’s price feed for the stock of movie theater chain, AMC, showed a spike to $772 on Sep. 15 and 17, a yawning disparity with conventional data providers like Yahoo Finance, which didn’t show AMC’s price rising higher than $50 on those days. 

BAD PRICING Pyth, which is a so-called oracle that bridges traditional finance and blockchain-based apps, is breaking one of the cardinal rules of the markets — don’t release bad pricing data.

🏹 Robinhood’s New Crypto Policy Poised to Bolster DeFi and NFTs

TLDR Robinhood, the wildly popular brokerage app, just made a move that could be a shot in the arm for DeFi. 

SO WHAT It plans to introduce crypto wallets in 2022 that will enable customers to deposit and withdraw Bitcoin, ETH, and other digital tokens from their accounts to external wallets. Robinhood’s current system doesn’t provide customers with a lot of mobility for their crypto assets, much to the frustration of its users.

SCALE With 21.3M active users and $102B in assets under custody, Robinhood’s new policy could unlock a wave of liquidity, a potential boon for the DeFi ecosystem. That could translate into more action for yield-bearing tokens and other Ethereum-inspired assets, and the purchase of NFTs. 

TEST Robinhood will test the new wallets with select customers in October, the company said on its website. The app will initially accommodate seven coins: Bitcoin, Bitcoin Cash, Bitcoin SV, Dogecoin, Ethereum, Ethereum Classic, and Litecoin.
