Block Street, a DeFi protocol focused on tokenized stock utilities, has successfully raised $11.5 million in a recent funding round. The project is among several gaining attention in October, alongside Gopher and Standx. Gopher, previously known as Masa, is rebranding and encouraging testnet interactions, hinting at a potential airdrop for participants. Meanwhile, Standx users are optimizing their rewards by creating single-sided USDT pools, which offer higher returns compared to standard DUSD staking. Additionally, T-REX, a consumer-oriented blockchain, is engaging users with testnet participation and badge rewards, potentially leading to future airdrops.
