​

1. EVM

​

Custodial Wallets

Crossmint manages private keys and transaction signing. These wallets are perfect for web2-like experiences where transaction approval, signing, and gas fee management are all handled on behalf of the user by Crossmint.

Crossmint supports two EVM custodial wallets types:

• Smart wallets: Contract-based wallets with programmable functionality (i.e. daily spending limits, multi-signature requirements etc.). Get started here.
• EOA wallets: Basic EVM wallets suitable for users with straightforward transaction needs. Get started here.

​

Non-Custodial Wallets

Users maintain complete control over their private keys and transaction signing. Perfect for traditional web3 experiences where users want direct control over their assets.

Available in two deployment models:

• Server-side: Environment-agnostic REST API endpoints to integrate wallet functionality in any application’s backend system. Get started here.
• Client-side: SDK to integrate wallet functionality directly in the browser, enabling seamless user interaction with dApps while maintaining self-custody of private keys. Get started here.
