Ambire: The EIP-7702 Wallet for a Better Web3

In an ideal world, Web3 wallets would be secure, intuitive, and powerful. Yet most wallets today still feel complicated, clunky, and limiting. They lack essential capabilities like cross-chain gas payments, efficient transaction management, robust security measures to prevent wallet drains, and simple account recovery options. One of the major underlying problems stems from the limited nature of standard Ethereum accounts, known as Externally Owned Accounts (EOAs).

Ethereum currently offers two main account types: the above-mentioned Externally Owned Accounts (EOAs)—controlled by private keys, like MetaMask or Rabby wallets—and Smart Accounts, managed by smart contracts with advanced features, like Ambire Wallet.

Smart Accounts promised enhanced security and usability, delivering significant improvements but requiring users to adopt new account addresses and unfamiliar security models. It seems this requirement significantly stalled the expected adoption, as most users prefer to keep their existing wallet addresses and familiar security practices.

Ethereum’s upcoming Pectra upgrade, featuring EIP-7702, addresses these adoption challenges by enabling existing EOAs to seamlessly gain Smart Account functionalities.

Ambire Wallet fully supports EIP-7702 and has already integrated it on Ethereum testnets. Ambire is ideally positioned to upgrade your existing wallet experience with smarter, seamless, and more secure capabilities from day one.

But before we review Ambire’s unique offerings, let’s unpack EIP-7702 and explore why it will have such a profound impact on Ethereum and the EVM ecosystems as a whole.

What is EIP-7702, and why does it matter?

EIP-7702 is an upcoming Ethereum improvement proposal, part of the highly anticipated Pectra upgrade. It allows Externally Owned Accounts (EOAs) to seamlessly adopt Smart Account functionalities without changing wallet addresses or private keys.

In a nutshell, it allows your current EOA wallet to perform Smart Account actions such as gasless transactions (sponsored gas, paying in ERC-20 tokens, etc.), transaction batching (bundling multiple actions into one transaction), enhanced security features like removing the need to manage token approvals (the number one reason for wallet drains), and onchain transaction simulations (seeing your future balance before signing).

Previous attempts at account abstraction, such as ERC-4337, required users to create entirely new wallets and adapt to unfamiliar security methods, which significantly slowed adoption. EIP-7702 successfully overcomes these challenges by enabling account abstraction directly within EOAs, turning them into Smart EOAs, and dramatically simplifying adoption and usability.

Benefits of EIP-7702 for existing wallets

EIP-7702 significantly enhances the usability, security, and efficiency of Ethereum EOA wallets. Here’s how it improves your experience:

Gasless transactions

EIP-7702 enables wallets to pay gas fees using stablecoins or other ERC-20 tokens instead of just ETH. Ambire Wallet pioneered this capability through its innovative Gas Tank feature, which allows cross-chain gas payments. For example, you can top up your Gas Tank with stablecoins on Ethereum and conveniently pay transaction fees across networks like Base, Optimism, or Arbitrum. Cool, right 😎

Transaction batching

With EIP-7702, you can bundle multiple transactions into one transaction, drastically reducing gas fees and enhancing efficiency. Ambire Wallet excels at transaction batching, optimizing this feature for Smart Accounts over time.

Now, EOAs can also enjoy these perfected efficiencies, making complex DeFi interactions seamless and significantly more affordable.

Advance onchain transaction simulation

Transaction simulation lets you see exactly what will happen to your account balance before approving a transaction. Instead of blindly signing transactions and hoping for the best, you’ll see precisely what tokens or assets you’re sending, receiving, or approving beforehand.

Limited token approvals

EIP-7702 introduces limited token approvals, allowing your wallet to approve only the required token amount for each transaction. This eliminates risks associated with unlimited spending permissions and significantly reduces vulnerabilities. Ambire Wallet was an early innovator of limited token approvals through its Smart Accounts, and now, your existing EOA can benefit from this critical security upgrade.

Account recovery and session keys

EIP-7702 allows for the implementation of advanced account recovery options like social guardians, email-based recovery, and even inheritance setups.

Session keys are another major upgrade coming to EOAs. With them, you can delegate specific permissions and allow limited access to certain (d)Apps or features without repeatedly signing transactions with your (hardware) wallet.

Both account recovery and session keys are features that will be available to Ambire Wallet users in the near future.

Why Ambire Wallet is the go-to EIP-7702 wallet

Ambire Wallet was built as a smart wallet from the beginning. It has already perfected key features like transaction batching, transaction simulation, and gasless payments (Gas Tank), which will soon be available to all EOAs through EIP-7702. This positions Ambire as the ideal wallet for the upcoming Ethereum ecosystem upgrade, dramatically enhancing onboarding, user experience, and security across EVM-compatible networks.

Ambire Wallet is the first wallet to support EIP-7702 from launch day. It's already integrated on Ethereum's Sepolia testnet, with a limited group of testers actively exploring these features.

Upgrading your wallet to use EIP-7702 features is simple—just a single transaction in your account within Ambire Wallet is all it takes. Bundle multiple actions using the Queue and Sign Later option on the transactions screen, as you would normally do with a Smart Account in Ambire, and you will be able to execute all in one transaction. Your account will become smarter without changing your wallet address, assets, DeFi positions, or private key.

Here's a video of the process on BNB Smart Chain (BSC), which recently implemented EIP-7702 through the Pascal hard fork.

Cool, but can I trust Ambire Wallet with my assets?

Ambire is design with the utmost security in mind. Our smart contract implementation is minimalistic, containing only around 200 lines of code. This simplicity reduces risks and makes the wallet extremely reliable. In addition, Ambire's code is undergoing rigorous auditing—over 10 extensive security audits so far—with no major vulnerabilities discovered.

Ambire Wallet was developed to ensure maximum security while maintaining usability. It supports all industry standard hardware wallet devices such as Trezor, Ledger, and Grid. You get EIP-7702 support on the Ethereum mainnet for software wallets from day one, as well as hardware wallets, as long as they support the necessary signatures. Ledger has already confirmed its aim to provide full EIP-7702 support at launch. 🚀

FAQ

Do I need to change my wallet or private keys to use the EIP-7702 features?

No. EIP-7702 lets your existing Ethereum wallet address (EOA) adopt smart account features without changing your private key or creating a new wallet. To enable the functionality, you simply perform a one-time upgrade transaction in Ambire, keeping your existing wallet address and security model unchanged.

Does EIP-7702 impact the security of my existing wallet?

No. EIP-7702 doesn’t weaken your wallet’s security. It enhances it by adding Smart Account features such as transaction batching, gas abstraction, and advanced onchain transaction simulation.

Can I continue using my hardware wallet with EIP-7702?

Yes. Your hardware wallet (e.g., Ledger, Trezor) remains fully compatible. EIP-7702 adds advanced capabilities to your existing wallet without changing how your hardware wallet operates.

Can I revert my wallet after upgrading to Smart EOA (EIP-7702 wallet)?

Yes. Your wallet remains fundamentally an EOA. While you gain Smart Account features in Ambire Wallet, you can always use your wallet as a traditional EOA whenever you prefer without losing functionality.

How much does it cost to upgrade my wallet to a Smart EOA?

The upgrade itself requires only a single transaction. The cost is similar to a typical smart contract interaction, but once completed, it saves significant gas fees through features like transaction batching and gas abstraction.

Will upgrading to a Smart EOA (EIP-7702 wallet) affect my existing tokens or assets?

No. Your tokens, assets, and DeFi positions remain unaffected. EIP-7702 simply enhances your wallet functionality without altering your existing balances or assets.

Can I use the same wallet address in multiple wallets after upgrading to Smart EOA?

Yes. You can still import your wallet account into multiple wallet providers. However, advanced Smart Account features (like batching or gas abstraction) may only be active in one wallet provider at a time. If you import your wallet into another EIP-7702-enabled wallet and delegate your private key to their smart contract, turning on the smart account capabilities again will overwrite the Ambire Smart EOA upgrade.

How does EIP-7702 handle account recovery?

Account recovery features are optional and wallet-specific. Wallet providers, including Ambire, may offer recovery methods such as guardians or email-based recovery in the future, giving you flexible control over your assets.

What happens if my Smart EOA loses access to the delegated contract?

Nothing critical happens. You still fully control your wallet via your private key. You can always revoke or change the delegated smart contract without losing control or access to your assets.
