Farcaster co-founder Dan Romero announced a major strategic shift for Farcaster, officially abandoning the "social-first" path that had failed to find product-market fit over the past 4.5 years and fully transitioning to a "wallet-driven" growth model. The team considers the newly launched, rapidly growing in-app wallet to be the closest feature to product-market fit to date, adopting a "use the tool (wallet) first, then retain the network (protocol)" strategy, aiming to convert every new wallet user into an active protocol user. Romero emphasized that the protocol itself will remain open and decentralized, but the official application will focus on the intersection of wallet and social features. Farcaster previously acquired the token issuance platform Clanker.

10. Hyperliquid will introduce Portfolio Margin in its network upgrade, unifying the link between spot and perpetual trading accounts.
The Hyperliquid blockchain will introduce a portfolio margin mechanism in its upcoming network upgrade, currently available as a pre-alpha on the testnet. This mechanism unifies spot and perpetual contract trading into a single account system to improve capital efficiency and automatically generate returns on unused borrowable assets in the account. Profits and losses from spot and perpetual positions can be hedged, reducing the liquidation risk of perpetual positions. Portfolio margin supports trading structures including hedging perpetual short positions with spot holdings and is applicable to all HIP-3 DEXs, but not all collateral assets are available for borrowing; new asset classes will be gradually supported in the future by HyperCore.
