Looks like someone exploited a pricing bug on ZeroFi's DRAM/USDC pool yesterday.
Over $4.7b was traded yesterday in this market, with around 400k transactions utilizing flash loans to buy DRAM and then immediately sell it back for a small profit.
In total, around $45k was stolen from a trading volume of about $4.7b
Trading volume for tokenized equities on @solana jumped 6x last week to $1.3b, driven by trading in SPCX and SPY.
@Raydium and @orca_so led the way, combining for 71% of total volume.
