etc. We'll put the translated content inside the tags.
Let's construct the JSON.
Note: We should use proper Japanese terms. For "lending" we use "レンディング" or "貸付"? In crypto context, "レンディング" is common. "DEX liquidity" -> "DEX流動性". "Smart Collateral" -> "スマート担保" (or "スマートコラテラル"? but "担保" is fine). "Smart Debt" -> "スマート負債" (or "スマートデット"? but "負債" is fine). "trading fees" -> "取引手数料". "staking rewards" -> "ステーキング報酬". "perpetuals" -> "永久先物" (or "パーペチュアル" but "永久先物" is common). "total value locked" -> "総ロック価値" (TVL). "lifetime PnL" -> "ライフタイムPnL" (or "通算損益" but keep as is). "LPing" -> "LP運用" (liquidity providing). "opt in" -> "オプトイン".
We'll keep proper nouns: Jupiter, Solana, Lend v2, USDC, USDT, SOL, JupSOL, DefiLlama, Kash Dhanda.
Now write the JSON.
Title: "Jupiter、SolanaでLend v2をローンチ、借入資産が取引手数料を獲得可能に" (I'll make it more natural: "Jupiter、SolanaでLend v2を開始、借りた資産が取引手数料を稼げるように" but keep "ローンチ" is fine. I'll use "ローンチ" as
