Mempool

Bitcoin’s mempool transaction count has surged after the Coldcard wallet hack, highlighting a wave of coin movement across wallets and exchanges. BTC remains confined to its recent trading band as market participants weigh policy risk around the Clarity Act and pressure from real Treasury yields.

A new wave of bitcoin sweeps tied to Coldcard-generated addresses may have lifted observed losses to about 1,816 BTC, or nearly $114 million, since July 30. Researchers say the latest pending transactions appear to use replace-by-fee, giving alert users a narrow window to outbid the attacker before confirmation.

DOG Mode, an alternative Bitcoin client associated with developer Leonidas, targets default relay policies rather than Bitcoin consensus rules. The debate has revived questions over Ordinals, censorship, fee markets, mempool fragmentation and who ultimately decides what the network should carry.
