The Future of Wallets: MPC vs Smart Wallets
summary
Compares MPC threshold signatures vs smart contract wallets using account abstraction, EIP3074 and EIP4337, and claims smart wallets are more flexible for mass onboarding. Lists concrete tradeoffs: off-chain recovery for MPC and true cross-chain support for MPC but with immutable auth rules and limited libraries; smart wallets enable social recovery, batching, gas sponsorship, time locks and seedless email onboarding. Gives measured costs: 1–2k gas per transaction and ~40k gas deployment added once, and concludes smart contract wallets are the more future‑proof path.
