Crossmint offers two types of wallet solutions: Custodial Wallets and Smart Wallets. To understand which option best suits your needs, visit the Wallets Introduction page.

Crossmint’s Smart Wallets are programmable, smart-contract based wallets, that provide enhanced flexibility, control, and security. Key features include:

  1. Non-custodial ownership: By default, you can let your users maintain complete control of their wallet and assets. Optionally, you can create keys to allow your users to delegate full or partial ownership of their account to you.
  2. Ability to sponsor gas fees: You can cover gas fees on behalf of your users, or have users pay them directly.
  3. Advanced control using installable modules: Extend the functionality of the wallet with features like asset recovery fallbacks, transaction guardrails for AI agents, transaction limits per day, and more.
