Strategies

This library includes DeFi protocol strategies. It undergoes continuous updates, expanding its functionality by incorporating new protocols and automated DeFi strategies. Unhosted Strategy Module

Overview

Installation

Hardhat, Truffle (npm)

$ npm install @unhosted/strategies  @openzeppelin/contracts

Foundry (git)

$ forge install Unhosted-Wallet/unhosted-strategies OpenZeppelin/openzeppelin-contracts

Also add

$ @unhosted/strategies/=lib/unhosted-strategies/src/  
$ @openzeppelin/contracts/=lib/openzeppelin-contracts/contracts/

to remappings.txt

Usage

If you're new to smart contract development, head to Developing Smart Contracts by openzeppelin to learn about creating a new project and compiling your contracts.

After installation, you have the flexibility to utilize the strategies by importing them. You can either build upon existing defi protocol strategies or create your own by inheriting from BaseStrategy. After constructing and deploying your strategy, add it to the Unhosted StrategyModule using the updateStrategy function. This makes your strategy accessible to all Unhosted users, allowing them to execute it and rewarding you with execution fees:

pragma solidity ^0.8.20;

import { UniswapV3Strategy } from "@unhosted/strategies/uniswapV3/UniswapV3Strategy.sol";
import { AaveV2Strategy } from "@unhosted/strategies/aaveV2/AaveV2Strategy.sol";

contract MyStrategy is UniswapV3Strategy, AaveV2Strategy {
  constructor(
    address wethAddress,
    address aaveV2Provider,
    address fallbackHandler
  )
    UniswapV3Strategy(wethAddress)
    AaveV2Strategy(wethAddress, aaveV2Provider, fallbackHandler)
  {}

  function getStrategyName()
    public
    pure
    override(UniswapV3Strategy, AaveV2Strategy)
    returns (string memory)
  {
    return "MyStrategy";
  }
}

[!IMPORTANT]

1. The strategy function can execute via call or delegatecall from the user's smart account. When using delegatecall, it's essential for strategies to prioritize security considerations and avoid modifying the SA's storage.
2. For functionalities requiring changes in the fallback handler, such as flashloans, the fallback manager slot is accessible in BaseStrategy. This slot can be temporarily updated to execute the desired logic.
