📑 **MPC Wallets: How Keyless Self-Custody Is Changing Crypto Wallet Security**

MPC (multi-party computation) wallets are emerging as crypto's fix for the seed-phrase problem, splitting signing authority across key shares instead of one point of failure.
• The stakes: a Coldcard firmware flaw let attackers regenerate seed phrases, draining up to **$130M** from self-custody wallets.
• Binance Wallet, built MPC-first with a 2-of-3 signing design, now commands **75%** of wallet trading volume — over **$13B** in daily volume.
• Context: spot DEX volumes are averaging over **$120B**, with the DEX-to-CEX ratio climbing to **33%** in August.
_The Block's take: MPC won't stop phishing or malicious approvals, but it removes the single-key catastrophic-loss risk that's kept mainstream users away from self-custody._
