Multisig and MPC wallets boost crypto security by distributing control. Multisig acts like a joint bank account, needing multiple "keys" to sign transactions transparently on-chain. It's great for clear, collaborative control but can be slower and expensive. MPC splits the private key into "shards" that never fully form, allowing transactions to be signed cooperatively without revealing the key. It offers top-tier security and a smoother user experience with smaller on-chain footprints. Choose Multisig for transparency and established tech, and MPC for ultimate security and seamless use.
