Ambire Launches EIP-7702 Smart Account Extension, Bringing Smart Contract Functionality to Existing Wallets

Ambire, a pioneer in self-custodial wallets, has officially launched the Ambire Extension, a browser-based wallet that natively supports Ethereum's upcoming EIP-7702.

Ambire, the leading provider of self-custodial wallets, today announces the official launch of the Ambire Extension—a browser-based wallet that natively supports Ethereum’s upcoming EIP-7702, enabling payment of gas fees in stablecoins and other tokens, removal of all token approvals, and introduction of smart account functionality with a simple UX for existing user accounts. This unlocks portable, programmable, and cost-efficient self-custody without requiring users to migrate their accounts.

Following nearly a year of private testing and refinement based on user feedback, the Ambire Extension is now publicly available with no invite codes for Chrome. Combining the benefits of smart account functionality with traditional EOAs (externally owned accounts), the extension allows users to retain their existing addresses while unlocking new features like transaction batching, gas abstraction, and programmable security.

“EIP-7702 is an inflection point for our industry: it lets us bring smart account capabilities directly to existing wallets without any friction,” said Ambire CEO Ivo Georgiev. “With the extension, we’ve built an architecture where your EOA is just as powerful as a smart account—secure, programmable, and multi-chain by design to make self-custody safer, and genuinely more usable.”

Ethereum’s Pectra upgrade introduces EIP-7702, a protocol evolution that allows EOAs to operate with the convenience of smart accounts without the need for complex migration or any loss of legacy compatibility. Ambire’s latest innovation combines this powerful functionality with a frictionless UX, built for speed, security, and composability:

Web3 users have long faced a trade-off between ease of use and advanced wallet functionality. Ambire’s support for EIP-7702 delivers a unified wallet experience, offering both power and simplicity for DeFi users, memecoin traders, and onchain explorers.

The Ambire Extension is now live and accessible to all users at ambire.com.
