Transactions supporting the popular CryptoKitties app are continuing to congest the ethereum blockchain, a state of affairs that has spurred at least one startup to briefly postpone its planned initial coin offering (ICO).

The token sale for SophiaTX, originally planned to start on Dec. 5, has been pushed back to ensure an orderly sale, the team behind the project announced today. SophiaTX, which is developing a blockchain platform for business-to-business use cases, said it will hold its ICO on Thursday, Dec. 7.

The problem, the team said, is that the activity around CryptoKitties – an ethereum-based app that uses tokens to represent digital cats that can be traded, exchanged or bred to create more e-pets – has effectively clogged up the blockchain.

As a result, users – including those trying to participate in token sales via the ethereum network – are stuck with longer wait times given the plethora of transactions associated with the CryptoKitties app.

"We have decided to delay the [token generation event] start by 48 hours because a very large number of participants will use ETH during and it would be a major disappointment if their attempted contributions wouldn't be processed timely and that would result in a significant backlog of transactions with very long waiting times," they said in a statement.

It remains to be seen whether the interest around CryptoKitties will lead to similar decisions. Statistics from ETHGasStation.infohttps://ethgasstation.info/index.php, a network data provider, suggests that the network congestion has eased somewhat compared to yesterday,

KuCoin Hits Record Market Share as 2025 Volumes Outpace Crypto Market

16:9 Image

KuCoin captured a record share of centralised exchange volume in 2025, with more than $1.25tn traded as its volumes grew faster than the wider crypto market.

What to know:

  • KuCoin recorded over $1.25 trillion in total trading volume in 2025, equivalent to an average of roughly $114 billion per month, marking its strongest year on record.
  • This performance translated into an all-time high share of centralised exchange volume, as KuCoin’s activity expanded faster than aggregate CEX volumes, which slowed during periods of lower market volatility.
  • Spot and derivatives volumes were evenly split, each exceeding $500 billion for the year, signalling broad-based usage rather than reliance on a single product line.
  • Altcoins accounted for the majority of trading activity, reinforcing KuCoin’s role as a primary liquidity venue beyond BTC and ETH at a time when majors saw more muted turnover.
  • Even as overall crypto volumes softened mid-year, KuCoin maintained elevated baseline activity, indicating structurally higher user engagement rather than short-lived volume spikes.

Silver nears $1 billion in volume on Hyperliquid as bitcoin remains frozen: Asia Morning Briefing

Blocks of silver (Scottsdale Mint)

Silver perps have more volume on Hyperliquid than SOL or XRP.

What to know:

  • Silver futures on the Hyperliquid crypto derivatives exchange have surged to become one of its most active markets, ranking just behind bitcoin and ether in trading volume.
  • The SILVER-USDC contract’s high volume, sizable open interest and slightly negative funding suggest traders are using crypto infrastructure for volatility and hedging in macro commodities rather than for directional crypto bets.
  • Bitcoin is holding near $88,000 in a "defensive equilibrium" with cooling ETF inflows, uneven derivatives positioning and rising demand for downside protection, while ether lags and capital rotates toward hard assets like gold and silver.
