The following is a guest position and an analysis by Nanfeng Jie, main product manager at Trust Wallet.
In recent years, we have seen a clear change in the way people interact with digital assets. More and more users are choosing self -sufficiency as a deliberate development towards greater control and responsibility. This trend is reflected in the rapid rise of tools as Trusted walletOne of the most used self-carriage portfolios on web3.
At Trust Wallet, we saw first -hand at what speed expectations evolve. Users want security more than security – they want simplicity. This insight guided our decision to become one of the first portfolios to support EIP-7702Ethereum’s latest proposal to make an outdoor accountant (EOAS) behaves like smart contracts. This is what has led to the development of flexgas, a feature that allows users to pay gas fees with tokens that they already hold, such as USDT, TWT or BNB, directly from their portfolio.
Now let’s take a step back and examine the context of the wider market and the real pain points that have led us to rethink the operation of gas costs.
Recent market research Values the non -guardian portfolio sector at 1.5 billion dollars in 2023, with projections reaching $ 3.5 billion by 2031, increasing to a TCAC by 8% from 2024 to 2031.

But the scale alone does not tell the whole story, because the user experience has not followed the pace. People still juggle the channels, manually manage gas sales and abandon transactions when approvals do not make sense.
One of the most common wallet elements that the wallet teams hear users are simple: “I don’t want to think about gas – I just want the transaction to pass.” And that’s a right point. Gas fees are not only a cost; They are a cognitive burden. Each transaction has failed or delayed confidence in the system.
The root of the problem lies in the architecture on which we have been leaning for more than a decade: EOA, the default portfolio type for most users. It is light and secure, but has not been designed for programmable dynamic interactions that define today’s decentralized applications (DAPP).
This is why the Ethereum EIP-7702 proposal represents such a significant change.
A new flexible layer for the behavior of the portfolio
First of all propose By Vitalik Buterin in May 2024, EIP-7702 introduced a subtle but essential evolution in the operation of Ethereum accounts. It allows the EOAs to temporarily take intelligent contract behavior in a single transaction, providing the advantages of the abstraction of accounts (AA) without forcing users to migrate to new types of account or abandon their control based on a seed sentence.


With EIP-7702, users maintain full custody of their assets while accessing a more flexible transaction logic. This means bringing together approvals and actions in a single tap, allowing recurring payments or supporting delegated session keys without separate intelligent contracts.
In simple terms, EIP-7702 means fewer steps, less confusion and a more fluid user experience. The transactions are faster and more predictable, allowing gas costs to be paid using tokens already held without the need for native assets in advance.
Technically speaking, EIP-7702 acts as a modular extension of the EOA model. The user signs an intention, which can contain a personalized logic, and the portfolio performs this intention via a temporary contract. Once the transaction is completed, the account comes back to its standard EOA state, unlocking a more intelligent transaction layer for developers and infrastructure providers.
In turn, web3 begins to behave more as something designed for real people, not the protocols.
Build the infrastructure behind abstraction
The management of the EIP-7702 on a scale requires more than integrating a new type of transaction or making User interface updates (IU). It requires a robust modular backend infrastructure capable of interpreting the intention of users, dynamically completing gas and reliably executing complex actions between the chains.
In the trusted portfolio, we have chosen not to count on third -party abstractions or SDKs. Instead, we have developed our own entirely internal account abstraction engine, designed to be secure, evolving and agnostic in chain. This modular system includes:
- Cashier – to manage personalized gas logic and gas -based gas payments
- Bundle – to optimize transactions in several steps
- Relay – for a robust and rapid submission of abstract transactions
- Gas provisional – to manage gas sources and routing on networks intelligently
This internal architecture gives Trust Wallet a lasting advantage of performance and reliability, while establishing a new standard for the design of intelligent portfolio based on EOA. He also paved the way for flexgas, the first important functionality that we built on this foundation. Flexgas allows users to pay gas fees with tokens such as USDT or TWT on Ethereum and BNB chain.
Above all, all these improvements preserve the essence of what makes self -sufficiency attractive: users retain total control of their private keys, their seed phrases remain unchanged and it is not necessary to move to a contractual portfolio. This balance (between power and autonomy) is what makes EIP-7702 such an important upgrade rather than a disturbing replacement.
Move portfolios into smart agents
If it is widely adopted, EIP-7702 could become a decisive layer in the next generation of web3 infrastructure. It allows a future where portfolios are reactive and intelligent agents – automate complex strategies, integrate users and unlock without large -scale friction interactions.
The first applications of the real world are already in motion. The features allowing users to pay gas with tokens that they already hold are almost there. Gas -free integration, automated execution strategies, portfolio models as a service and intelligent transaction policies for the use of institutional quality are all at hand.
The greatest breakthroughs of the crypto often do not come from radical revisions, but from silent upgrades which eliminate invisible friction. EIP-7702 can be exactly that. This does not change our way of thinking about Ethereum’s safety model – that changes what this model can do for users.
Because at the end of the day, progress in web3 does not depend on how our contracts are intelligent. It depends on how they feel natural to use.
