|---|---|---|
Account Recovery | ||
Gas Fee Sponsorship (Paymaster) | ||
Batch Transactions | ||
Session Keys for UX | ||
Multi-Factor Security | ||
Initial Development Time | 2-4 weeks | 4-8 weeks |
Ongoing Gas Cost | Standard | ~10-15% higher (flexibility trade-off) |
User Onboarding Friction | High (seed phrase) | Low (social/email) |
Smart Contract Dependency | No | Yes (requires deployment) |
Ideal Use Case | Simple transfers, experienced users | Mass-market dApps, subscriptions, gaming |
