About
TxFusion is a platform designed to simplify and improve the user experience in managing multiple DEFI transactions. It leverages the new EIP5792 standard, introducing a new wallet method called `wallet_sendCalls`. This method enables users to create batch transactions, allowing them to execute multiple actions with a single call and signature. ## Existing Problem: DeFi users often struggle with the complexity of managing numerous transactions across various protocols like Uniswap, Compound, and Aave. This process can be time-consuming and cumbersome, leading to a less-than-ideal user experience. It also requires more gas fees for the user to execute multiple transaction ## Solution: We address this challenge by providing a unified platform that simplifies the execution of multiple DeFi transactions. ## How It Works: 1. Account Recognition: TxFusion batches multiple transaction in a defined format into an array of contract calls to either an EOA or Smart Contract Wallet and then send using wallet_sendCalls() to the wallet 2. Wallet recognises the type of Account the request is for i.e. an EOA or SCW and then requests the user to generate a signature accordingly 3. Signature Generation For EOAs - It utilizes EIP3074 for signature generation, which uses the AUTH & AUTHCALL opcode to allows execution of batch transactions. For SCWs - Generate a batched transaction User operations , which has to be then signed by the user respective to EIP4337. 4.Execution: Signed transactions are executed via Invoker for EOAs or via a Bundler for SCWs, ensuring swift and secure transaction processing.
How it's made
We utilized the new EIP5794 which introduces these new methods for a wallet to accept batch transactions and then accordingly process it. Currently only a few wallets support the wallet_sendCalls method , namely Coinbase Smart Contract Wallet SDK , which was implemented in this application too. **Viem/experimental** provided us with methods for EIP5792 , which we used for adding the functionality for this application to send Calls and also track the status of the transactions sent. **Next.js** is the frontend Framework and **TypeScript** as the language to provide type safety across the application. **TailwindCSS** and **ShadCN UI** for designing the frontend.
