Privy makes it easy to create smart wallets for your users. Smart wallets are programmable, onchain accounts that incorporate the features of account abstraction. With just a few lines of code, you can create smart wallets for your users to sponsor gas payments, send batched transactions, and more.
We recommend using our native gas sponsorship offering to sponsor transactions on EVM and Solana. Learn more
Please note that this native smart wallet integration is only available in the React and React Native SDKs. To configure smart wallets with wallets created using server-side SDKs or APIs, follow this guide.
Sample enable smart wallets To set up with smart wallets, start by enabling smart wallets in the Privy Dashboard. This will configure your app to create smart wallets for your users controlled by Privy embedded signers.

Native ERC-4337 support with embedded signers

Under the hood, a smart wallet is an ERC-4337-compatible smart contract deployed onchain. This smart contract can be programmed to support features like transaction batching, gas sponsorship, delegating permissions, and more. When using a smart wallet, a user’s assets are held by the smart contract itself. This smart contract is controlled by an embedded signer (an externally-owned account) secured by Privy’s self-custodial wallet infrastructure. Privy automatically takes care of creating signers for users and generating smart contract wallets controlled by these signers. Your app can customize which ERC-4337 account implementation powers your users’ smart wallets, between Kernel (ZeroDev), Safe, LightAccount (Alchemy), Biconomy, Thirdweb, and the Coinbase Smart Wallet.
Privy partners with the ERC-4337 account providers above to ensure a smooth experience. If you’d like us to add support for another, please reach out!

Gas sponsorship with paymasters

With smart wallets, your app can pay for gas fees simply by registering a paymaster URL in the Privy Dashboard. Privy will automatically route gas payments from your registered paymaster instead of your users’ wallets, allowing your users to transact on-chain instantly –– even if they don’t have a balance in their smart wallet.

Future-proofed for the latest standards

Privy works closely with the teams building the next generation of account abstraction standards on top of ERC-4337, such as permissions & session keys (ERC-7715), smart wallet modules (ERC-7579), and smart account discovery (ERC-7555) across different applications. As these standards become ratified, Privy will incorporate native support for these features.
