On December 19, 2025, Cardano's development firm outlined an interchain roadmap to move beyond a single-chain paradigm. The five-year Cardano Vision coordinates 34 research streams across nine areas, with initiatives such as Cardinal—a trust-minimized Bitcoin–Cardano bridge—and partner chains intended to extend capabilities while preserving the network's security model.

In 2025, Solana’s network revenue has accelerated, with yearly figures reportedly on track to exceed Ethereum’s for the first time as on-chain activity and RWA growth surge. Data shows Solana’s revenue rising from $28 million in 2021 to $2.5 billion YTD in 2025, while Ethereum has declined to about $1.4 billion. Although the SOL/ETH price ratio has spent 2025 in a bearish trend, Solana still logged a 12-month high around 0.93 in mid-January, keeping the contest between the two L1s firmly in focus going into 2026.

Ethereum is confined between a long-standing descending trendline and a major $2.5K support on the daily chart, with volatility shrinking and rallies fading. On-chain flows turned cautious in the week beginning December 15, as spot ETH ETFs saw over $600M in net outflows, including roughly $467M from BlackRock's ETHA, according to Shayan.

On Dec. 17, Coinbase announced a partnership with prediction markets operator Kalshi to let U.S. customers trade event contracts, and on the following Friday it said it had filed lawsuits in states including Connecticut, Michigan and Illinois over related gambling law issues. Ripple CTO David Schwartz then joined an X discussion, clarifying how event contracts are classified as derivatives, while XRPL’s protocol-native lending system targeting institutional credit markets is expected to move into validator voting in late January 2026.

According to the publication, crypto markets are rebounding, with Bitcoin at $88,000 and Ethereum nearing $3,000. Meme coins led by Pepe, Fartcoin and Pippin are showing strength, while Dogecoin gained 2.5% in 24 hours, reclaimed $0.13, and is watching the $0.15 resistance. The article also flags Pepenode and Maxi Doge presales.

CryptoQuant analyst PelinayPA links XRP weakness in 2025 to rising exchange inflows from 100K–1M and 1M+ whale bands. Despite the mid‑November launch of US spot XRP ETFs, SoSoValue reports over $1.14 billion in assets and no negative outflow days, yet price hovers near $1.90 with risk toward $1.50–$1.60.

Swift said in late September 2025 it began designing a shared blockchain ledger with a group of 30+ banks and will prototype it with Consensys. At the same time, Ethereum’s exchange supply ratio is about 0.137, marking its lowest reading since 2016, while charts show ETH near $2.9K.

Solana is trading around $126 after a volatile December, with price moving in a corrective downtrend while a $140–$145 resistance band caps the upside. Anthony Scaramucci has outlined a 5–10 year vision in which SOL could climb to $2,500, based on expectations for large-scale tokenization and clearer US regulation. Technical indicators show SOL consolidating between $121–$122 support and $130–$133 resistance, leaving traders watching $133.80–$140 for signs of a breakout.
