This is the most important bottom-up innovation recently, yet it has been overlooked by many.

EIP-7702 is quietly upgrading wallets from "keys" to "on-chain app platforms".

In the future, with just one click, the wallet can automatically install plugins, run logic, sign transactions, cross chains, and revert back to a normal account, all with just one transaction.

📦 Let’s compare it with a daily example:

🥡 In the past: You are a delivery person.

You open the wallet:

First sign permission → One transaction.

Then go to DEX for trading → Second transaction.

Then go to another protocol to deposit → Third transaction.

Every step requires your personal operation and multiple gas fees.

The wallet is just a key; you have to do everything yourself.

📦 After EIP-7702: You are the customer, and the wallet is the delivery platform + robot.

You just say: "I want to deposit and earn yield."

The wallet will automatically:

Call the contract to complete authorization.

Go to multiple DEXs for currency exchange.

Call the strategy contract to bundle execution.

All done in one transaction ✅

Just like you open Meituan and say, "I want a low-carbon meal set," the platform automatically prepares the meal, places the order, and dispatches the rider, all in one go.

Therefore, moving forward, the entire business model of DeFi will be completely overturned:

1️⃣ The wallet becomes an App Store, and developers become plugin vendors.

The wallet (like DeFiApp) can load functional modules based on user needs, such as "Swap Plugin", "Strategy Plugin", "Cross-Chain Bridge Plugin".

Developers no longer face end-users; instead, they write modules and hand them over to wallets for distribution and invocation.

✅ Business opportunity: The wallet controls the distribution entrance, and in the future, it can earn revenue based on invocation volume and strategy sharing, becoming a platform project.

2️⃣ Protocols begin to "passively serve" instead of "actively attracting users".

Protocols like Aave and Uniswap will no longer rely on front-end to attract traffic but will write modules for other wallets to call.

They become "basic service providers" on-chain.

✅ Business change: Protocol to user → to wallet → to user,

An additional layer of "account platform" is added in between.

3️⃣ The value of wallet entry skyrockets, starting to monetize.

Currently, wallets monetize through ads and transaction rebates;

In the future, wallets can also:

Lead transaction paths (choose which DEX, which bridge to take)

Charge strategy invocation fees

Embed "recommendation modules" and "priority strategies" to charge service fees.

✅ Business change: Wallet = one-stop entry + on-chain distribution platform + user behavior traffic pool, with profit margins far exceeding the current situation.

😮 Huh? Isn’t this DeFiApp @defidotapp?

Chain abstraction aggregators like DeFiApp are becoming the core entry point for this paradigm shift:

✅ Users operate in just one app, but behind it can:

Call any contract on any chain;

Execute any combination of strategies;

Manage asset flow and risk.

In other words, DeFiApp is one of the "productized carriers" of the EIP-7702 idea.

🔚

EIP-7702 upgrades the "wallet" from a key tool to an "on-chain operation platform"; it transforms a single click into a customized execution and shifts on-chain business from "protocol-centric" to "account-centric".

Chain abstraction entries like DeFiApp are among the first to land in this paradigm shift.

In the future, one-click operations, automatic cross-chains, and strategy combination executions will all happen here.
