Ledger Multisig Adoption Gains Attention
As bitcoin and crypto hardware wallet manufacturers and users face security challenges, the use of multivendor multisig hardware wallets is gaining traction. Technically savvy bitcoiners have been using this approach for years. Following recent incidents involving Ledger and Coldcard, the approach is now attracting more attention from the wider audience. Multivendor multisig combines hardware from different manufacturers in a multisignature wallet setup, where two out of three keys are needed to sign a transaction. This setup provides better security, as compromising all devices in a single vendor's supply chain attack is difficult. The safest practice is to buy hardware wallets directly from the manufacturer, but this reduces risks rather than eliminating them. Developers and wallet providers are developing their own multisig solutions, though they do not yet support all available hardware wallets. If multivendor multisig becomes the standard, users could face additional expenses, but the investment could pay off in the long term. Manufacturers and multisig solution providers could benefit from this trend, as users would no longer look for a single 'best' hardware wallet. However, the trend's popularity will depend on how users perceive the risks and whether they adopt more user-friendly and less risky solutions.
