Why web3 developers should implement smart contract wallets

Smart contract wallets vs. externally owned accounts (EOAs)

Most wallets are externally owned accounts (EOAs) that are controlled by a user and accessed via a private key.

A smart contract wallet (a.k.a. smart wallet) is managed by the code in a smart contract rather than by a private key. This code enables advanced functionality for users, such as multisig security, key rotation, account recovery, transaction bundling, gasless transactions, social or email login and fiat-to-crypto onramps.

Let’s explore how smart wallets are emerging as a foundational consumer-facing web3 product that can accelerate mainstream adoption of tokenized assets and web3 applications.

1. Better security for users

Because funds are stored in a smart contract, a smart contract wallet can be controlled by multiple keys — all while remaining non-custodial.

This multi-signature design allows keys to be added, removed and replaced. With EOAs, on the other hand, the private key is a single point of failure.

Decentralized two-factor authentication and social account recovery add additional layers of security to smart wallets.

Smart wallets also provide a pathway to quantum-safe cryptography in the future, without requiring users to migrate their funds to a new wallet.

2. Transaction bundling

Smart wallets can bundle multiple transactions into a single transaction, abstracting away the token approval process to allow for lower fees and a smoother user experience.

Users only need to perform a single click for cheaper gas and a streamlined experience, rather than undertaking a more complex and costly process to approve multiple transactions.

3. Zero fees for users

Transaction bundling saves on fees but smart contract wallets can also be programmed to enable gasless transactions.

Developers can sponsor transactions for their users, so that users will never have to pay gas fees to use their game or dapp.

4. Better user experience

With social or email login, users can create a smart contract wallet in just two clicks, without the need to download an app or use a seed phrase.

The option to access fiat-to-crypto onramps to buy crypto and NFTs with debit and credit cards makes purchasing digital assets simple and seamless and brings greater convenience to users.
