Solana

Michael Arrington, founder of TechCrunch and CrunchBase, recently disclosed on social media that XRP is one of his five largest crypto holdings by dollar value, alongside Bitcoin, Ethereum, Solana and Immutable. His post sparked heavy engagement and debate among market participants over portfolio construction and what his choices might signal. XRP’s price action has been volatile in 2025, with the token trading around $1.98 in mid-December after previously reaching nearly $3.65 in July.

According to CoinGlass, SOL’s seven‑day liquidation heatmap shows short‑side risk dominating, with nearly double the potential liquidations versus longs. A push toward $147 this week could unleash up to $1 billion in short covers, while a drop below $120 threatens roughly $500 million in long liquidations. Fund flows and key chart levels now frame the next move.

On 16 December, the article highlights XRP, Midnight and Sui while Bitcoin trades below 90,000. Over the past 24 hours, BTC fell 2.6% and is around 87,158. XRP recently retraced to about 1.92 after a seven-year high, while Sui touts high throughput and Midnight focuses on privacy on Cardano.

On 16 December 2025, Solana started evaluating post‑quantum cryptography on a test network in collaboration with Project Eleven. The initiative focuses on migration paths and quantum‑resistant signature schemes rather than immediately replacing Ed25519, reflecting a wider effort to future‑proof blockchain security.

The XRP Ledger Foundation has called on XRPL node operators and developers to urgently upgrade to rippled v3.0.0, which introduces several new but inactive amendments and core ledger fixes. Shiba Inu is trading near a downside liquidation area around $0.00777, while Solana has recorded a 40% surge in trading volume alongside a bullish golden cross pattern as its price recovers toward $132.9.

On December 16, 2025, Solana announced a partnership with Project Eleven to develop and test quantum-resistant digital signatures on a Solana testnet. The initiative includes a full quantum-readiness assessment of wallets, validators, and transaction flows. Solana's founder Anatoly Yakovenko has previously cited a 50% probability of quantum attacks against Bitcoin in the coming years, while current threats remain theoretical.

According to data from Pipe, Solana's network absorbed a distributed denial-of-service attack peaking around 6 terabits per second this week without downtime or notable fee spikes, a performance later confirmed by co-founders Anatoly Yakovenko and Raj Gokal. The event coincides with a more than 35% drop in active validators in 2025 and growing concentration of stake among large infrastructure providers, even as Solana processes roughly $1.6 trillion in annual trading volume and supports about $15 billion in stablecoins.

PIPPIN jumped to a fresh all‑time high on December 16 following a sharp squeeze in derivatives. Shorts dominated open interest, while on‑chain whales executed coordinated spot orders on Raydium and PumpSwap. The team made no new announcements during the move.

Invesco and Galaxy Digital launched the staked Solana ETP QSOL on Monday, listing it on the Cboe BZX U.S. equities exchange with 17,500 SOL in custody valued at $2.19 million and a 0.25% total expense ratio. Crypto ETF flows diverged the same day, with Bitcoin spot ETFs seeing $357.69 million in outflows and Ethereum $224.78 million, while Solana products recorded $35.2 million in net inflows.

Singapore-based StraitsX plans to extend its XSGD and XUSD stablecoins to Solana by early 2026. The move targets automated payments and onchain SGD–USD exchange, with the pair having processed over $18 billion in onchain transactions. StraitsX operates under MAS oversight and is exploring a consumer pilot with Grab.
