The following is a guest post and analysis by Nanfeng Jie, Lead Product Manager at Trust Wallet.
In recent years we have seen a clear shift in how people deal with digital assets. More users opt for self -coasts as a deliberate movement in the direction of more control and accountability. This trend is reflected in the rapid rise of tools such as Trust WalletOne of the most commonly used self -spice portfolios in web3.
At Trust Wallet we have seen first -hand how quickly the expectations evolve. Users want more than security – they want simplicity. That insight led our decision to become one of the first portfolios that support EIP-7702The latest proposal from Ethereum to make external ownership accounts (EOAs) behaves like smart contracts. It is what led to the development of Flexgas, a function with which user can pay gas costs with tokens that they already have, such as USDT, TWT or BNB, directly from their wallet.
Now let’s take a step back and investigate the wider market context and the Real-World pain points that led us to reconsider how gas costs should work.
Recent market research The non-guardianship sector does not appreciate $ 1.5 billion in 2023, with projections of $ 3.5 billion in 2031, grows by a CAGR from 8% from 2024 to 2031.
But scale alone does not tell the whole story, because the user experience has not kept pace. People still juggle chains, manage gas balance sheets and leave transactions when approvals are not logical.
One of the most common pieces of feedback portemonent teams hearing users is simple: “I don’t want to think about gas – I just want the transaction to go through.” And it’s a reasonable point. Gas costs are not just a costs; They are a cognitive burden. Every failed or delayed transaction ships away to trust in the system.
The root of the problem lies in the architecture that we have been familiar with for more than ten years: EOA, the standard wallet type for most users. It is lightweight and safe, but is not designed for the programmable, dynamic interactions that define the current decentralized applications (DAPPs).
That is why the EIHEEUM EIP-7702 proposal represents such a meaningful shift.
A flexible new layer for wallet behavior
First suggested By Vitalik Buterin in May 2024, EIP-7702 introduces a subtle but essential evolution to how Ethereum accounts work. With this, EOAs can temporarily accept smart contract behavior within a single transaction, which brings the benefits of account abstraction (AA) without forcing users to migrate to new account types or to give their sense of seed -based control.
With EIP-7702, users retain full custody of their assets and get access to more flexible transaction logic. That means bundling approvals and actions in a single tap, making recurring payments possible or supporting delegated session keys without separate smart contracts.
Simply put, EIP-7702 means fewer steps, less confusion and a smoother user experience. Transactions are faster and more predictable, so that gas costs can be paid with the help of tokens that are already being held without in advance for native assets.
Technically, EIP-7702 acts as a modular expansion of the EOA model. The user signs an intention that may contain custom logic, and the wallet carries out that intention through a temporary contract. Once the transaction is completed, the account returns to its standard EOA state, which unlocks an intelligent transaction layer for developers and infrastructure providers.
In turn, Web3 starts to behave more like something built for real people, not for protocols.
Building the infrastructure behind the abstraction
Support from EIP-7702 on a scale requires more than integrating a new transaction type or making user interface (UI) updates. It requires a robust, modular backend infrastructure that is able to interpret user intention, dynamic routing gas and to perform complex actions reliably about chains.
At Trust Wallet we chose not to rely on external abstractions or SDKs. Instead, we have developed our own account abstraction motor in -house, built to be safe, scalable and chainagnostic. This modular system includes:
- Paymaster -For the processing of adjusted gas logic and token -based gas payments
- Bundler -For optimizing multi -step transactions
- Consultant – for robust, rapid submission of abstracted transactions
- Gas inventor – For managing gas sources and rousting on networks in an intelligent way
This internal architecture gives Trust Wallet a sustainable lead in performance and reliability, while a new standard is set for EOA-based Smart Wallet design. It also paved the road for Flexgas, the first prominent function that we built on this basis. With Flexgas, user can pay gas costs with tokens such as USDT or TWT on Ethereum and BNB chain.
It is crucial that all these improvements retain the essence of what makes self -confidence attractive: users retain full control over their private keys, their seed sentences remain unchanged and it is not necessary to upgrade to a contract -based wallet. This balance (between strength and autonomy) makes EIP-7702 such an important upgrade instead of a disturbing replacement.
Wallets shift to intelligent agents
If much is hired, EIP-7702 could become a determining layer in the next generation of Web3 infrastructure. It makes a future possible in which portfolios are responsive, intelligent agents – complex strategies, onboarding users and frictionless interactions on scale.
The first Real-World applications are already on the move. Functions with which users can pay for gas with tokens that they already have are almost here. Gasless onboarding, automated implementation strategies, wallet-as-a-service models and smart transaction policy for the use of institutional quality are all within reach.
The biggest breakthroughs in crypto often do not come from radical overhaul, but from silent upgrades that remove invisible frictions. EIP-7702 can be exactly that. It does not change the way we think about Ethereum’s security model – it changes what that model can do for users.
Because at the end of the day the progress in web3 does not depend on how smart our contracts are. It depends on how natural they feel to use.
