Jupiter DEX has acquired lending platform RainFi and welcomed former KKR strategist Xiao-Xiao J. Zhu onboard as its new president.

Jupiter plans a gradual integration of RainFi, which aims to scale credit markets through fixed‑term loans, and its core features over the next few months. Meanwhile the app will continue under its own banner during the transition.
stJUP deposits now remain closed, though users can withdraw from Liquid while rewards continue until the next ASR cycle concludes. On the other hand, stCOLLAT operations will continue without change.
stJUP deposits are now stopped, and users are invited to unstake from Liquid.
Positions will continue to generate staking rewards until the next ASR distribution and the shutdown of Liquid.
stCOLLAT is not affected by this transition, and staking continues normally for them.

A New President
Jupiter also appointed Xiao‑Xiao J. Zhu as its new president. After five years at KKR, where he was responsible for digital asset strategy and worked on major technology deals, Zhu will now focus on Jupiter’s expansion into “the default onchain gateway to the world.”
He said in a post on X that value in crypto “is fundamentally shifting from infrastructure to the application level,” where liquidity, distribution, and user experience form the core advantage.
After five wonderful years at KKR, I am excited to share that I am joining @JupiterExchange, the leading onchain super-app on @Solana, as President.
Here’s why.

Under his leadership, Jupiter aims to leave a lasting impact with its role as Solana’s largest full‑stack DeFi platform.
The team oversees more than $3 billion in TVL and over $1 trillion in annualized activity across trading, lending, staking, and other product lines.
According to the new Jupiter President, the DEX will now double down on “stablecoins, payments, and an omnichain hub that connects ecosystems and liquidity layers.”
JUP Token Tanks
JUP has fallen more than 8% in the past day and nearly 39% this month. At $0.2137, the token now sits almost 90% below its all‑time high from more than two years ago.
The decline comes despite Coinbase launching spot trading for Jupiter pairs on December 9 and the launch of Ultra v3, the DEX’s upgraded trading engine.
