The stablecoin USX on the Solana chain has experienced severe fluctuations in the secondary market, once decoupling and dropping to $0.1, allegedly due to a depletion of liquidity.The Solstice team responded by stating that the decoupling of USX on the Solana chain is a secondary market liquidity issue. The team and market makers are working to resolve this and are injecting liquidity into the secondary market to ensure market stability. "The net asset value of USX's underlying assets and the assets held in custody by Solstice are completely unaffected, and the collateralization rate exceeds 100%. We have now requested a third party to issue a supplementary certification report immediately, and the team will release it as soon as the report is completed."The team emphasized that this is purely a secondary market liquidity issue, liquidity has been injected to restore stability, and the current price has risen to $0.94, with the primary market operating normally for 1:1 redemptions.

Aptos ecosystem's native enhanced yield infrastructure Goblin Finance officially launched its core product GoAPT today, aiming to build a yield infrastructure for Aptos centered around real strategy profit sharing.Unlike traditional LSTs that only map the basic staking APR, GoAPT not only retains about 6.5% of the network's basic yield but also channels the real yield from the strategy vault GoVault back to the token price, with the overall APT annual yield potentially reaching up to 1.3 times the original. Goblin stated that while the basic modules such as DEX, lending, and stablecoins in Aptos have gradually matured, the yield layer is still in a blank stage.Goblin creates a "sustainable yield flywheel" through the GoAPT + GoVault combination: strategy yield enters GoAPT price → attracts more APT staking → drives Vault yield growth → continuously benefits users. Currently, GoVault has deployed diversified professional strategies, such as Automated Liquidity Management (ALM). Additionally, Delta-Neutral hedging and CeDeFi robust arbitrage strategies will soon be launched, with annual coverage in the range of 20%--50%.Users only need to stake APT to participate in the strategy system and obtain compounded yields. Goblin will continue to expand the strategy matrix in the future, promoting GoAPT to become a high-trust asset and liquidity standard in the Aptos ecosystem, empowering various scenarios such as lending and re-staking, further unlocking the yield potential of the Aptos network.

Arthur Hayes Family Office Maelstrom co-founder and investment director Akshat Vaidya posted on X, "I invested $100,000 in the Pantera Early-Stage Token Fund LP four years ago, and now it's down to $56,000 because Pantera charges a 3% management fee and a 30% performance fee. Over these four years, Bitcoin has doubled, and many seed-stage projects have surged 20-75 times; however, this fund's fees have nearly wiped out half of the LP's capital. While the investment years are important, losing 50% in any cycle is truly the worst performance."
