FeeRoute

Main Contract: ./contracts/SmartRoute/DODORouteProxy.sol

DODORouteProxy is a new routeProxy contract with fee rebate to manage all route. It provides three methods to swap, including mixSwap,multiSwap and externalSwap. Mixswap is for linear swap, which describes one token path with one pool each time. Multiswap is a simplified version about 1inch, which describes one token path with several pools each time. ExternalSwap is for other routers like 0x, 1inch and paraswap. Dodo and front-end users could take certain route fee rebate from each swap. Wherein dodo will get a fixed percentage, and front-end users could assign any proportion through function parameters.

Inheritaged a template using Foundry && HardHat architecture. We use hardhat test.

Motivation

With this new architecture, we can get:

• Unit tests written in solidity
• Foundry's cast
• Integration testing with Hardhat
• Hardhat deploy & verify
• Typescript

Foundry

Foundry is a blazing fast, portable and modular toolkit for Ethereum application development written in Rust.

Foundry consists of:

• Forge: Ethereum testing framework (like Truffle, Hardhat and Dapptools).
• Cast: Swiss army knife for interacting with EVM smart contracts, sending transactions and getting chain data.

Need help getting started with Foundry? Read the 📖 Foundry Book (WIP)!

Hardhat

Hardhat is an Ethereum development environment for professionals. It facilitates performing frequent tasks, such as running tests, automatically checking code for mistakes or interacting with a smart contract.

On Hardhat's website you will find:

• Guides to get started
• Hardhat Network
• Plugin list

Installation

Foundry

First run the command below to get foundryup, the Foundry toolchain installer:

curl -L https://foundry.paradigm.xyz | bash

If you do not want to use the redirect, feel free to manually download the foundryup installation script from here.

Then, in a new terminal session or after reloading your PATH, run it to get the latest forge and cast binaries:

foundryup

Advanced ways to use foundryup, and other documentation, can be found in the foundryup package. Happy forging!
