What is Umee?

Umee is a cross-chain decentralized non-custodial liquidity markets protocol where users can participate as depositors or borrowers. Depositors provide liquidity to the market to earn a passive income, while borrowers are able to borrow in an overcollateralized (perpetually) or undercollateralized (one-block liquidity) fashion.

Documentation

The documentation of Umee V1 is in the following Umee V1 documentation link. At the documentation you can learn more about the protocol, see the contract interfaces, integration guides and audits.

For getting the latest contracts addresses, please check the Deployed contracts page at the documentation to stay up to date.

Connect with the community

You can join at the Umee Discord channel for asking questions about the protocol or talk about Umee with other peers.

Getting Started (this is for protocol not Umee)

You can install @aave/protocol-v2 as an NPM package in your Hardhat, Buidler or Truffle project to import the contracts and interfaces:

npm install @aave/protocol-v2

Import at Solidity files:

import {ILendingPool} from "@aave/protocol-v2/contracts/interfaces/ILendingPool.sol";

contract Misc {

  function deposit(address pool, address token, address user, uint256 amount) public {
    ILendingPool(pool).deposit(token, amount, user, 0);
    {...}
  }
}

The JSON artifacts with the ABI and Bytecode are also included into the bundled NPM package at artifacts/ directory.

Import JSON file via Node JS require:

const LendingPoolV2Artifact = require('@aave/protocol-v2/artifacts/contracts/protocol/lendingpool/LendingPool.sol/LendingPool.json');

// Log the ABI into console
console.log(LendingPoolV2Artifact.abi)

Setup

The repository uses Docker Compose to manage sensitive keys and load the configuration. Prior any action like test or deploy, you must run docker-compose up to start the contracts-env container, and then connect to the container console via docker-compose exec contracts-env bash.

Follow the next steps to setup the repository:

  • Install docker and docker-compose
  • Create an enviroment file named .env and fill the next enviroment variables
# Mnemonic, only first address will be used
MNEMONIC=""

# Add Alchemy or Infura provider keys, alchemy takes preference at the config level
ALCHEMY_KEY=""
INFURA_KEY=""


# Optional Etherscan key, for automatize the verification of the contracts at Etherscan
ETHERSCAN_KEY=""

# Optional, if you plan to use Tenderly scripts
TENDERLY_PROJECT=""
TENDERLY_USERNAME=""

Markets configuration

The configurations related with the Umee Markets are located at markets directory. You can follow the IUmeeConfiguration interface to create new Markets configuration or extend the current Umee configuration.

Each market should have his own Market configuration file, and their own set of deployment tasks, using the Aave market config and tasks as a reference.

Test

You can run the full test suite with the following commands:

# In one terminal
docker-compose up

# Open another tab or terminal
docker-compose exec contracts-env bash

# A new Bash terminal is prompted, connected to the container
npm run test

Deployments

For deploying Umee Protocol V1, you can use the available scripts located at package.json. For a complete list, run npm run to see all the tasks.

Kovan deployment

# In one terminal
docker-compose up

# Open another tab or terminal
docker-compose exec contracts-env bash

# A new Bash terminal is prompted, connected to the container
npm run umee:kovan:full:migration

Creating A Market

1. Duplicate the Umee Market folder
- Update Commons Addresses
- Update Index strategies, reserves, reserveConfigs
- Update ratestrategies and reserveconfigs, if needed

2. Update helpers/configuration file
- import market config
- Update confignames, loadpoolconfig, and getreservesconfigbypool

3. Duplicate umee:mainnet task
- Update folder
- Add migration script in package.json

Adding Network

Local Fork Testing

1. Run npx hardhat node --fork https://eth-rinkeby.alchemyapi.io/v2/your-key
- Create another terminal

2. Update hardhat config file
- Uncomment URL and comment out network URL
- Change chain ID to localhost
- Comment out hardhat account:field

3. Update .env mnemonic to test account

4. Run Migration

Mainnet fork deployment

You can deploy Umee Protocol V1 in a forked Mainnet chain using Hardhat built-in fork feature:

docker-compose run contracts-env npm run umee:fork:main

Deploy UMEE into a Mainnet Fork via console (not configured yet)

You can deploy Umee into the Hardhat console in fork mode, to interact with the protocol inside the fork or for testing purposes.

Run the console in Mainnet fork mode:

docker-compose run contracts-env npm run console:fork

At the Hardhat console, interact with the Umee protocol in Mainnet fork mode:

// Deploy the Aave protocol in fork mode
await run('umee:mainnet')

// Or your custom Hardhat task
await run('your-custom-task');

// After you initialize the HRE via 'set-DRE' task, you can import any TS/JS file
run('set-DRE');

// Import contract getters to retrieve an Ethers.js Contract instance
const contractGetters = require('./helpers/contracts-getters'); // Import a TS/JS file

// Lending pool instance
const lendingPool = await contractGetters.getLendingPool("LendingPool address from 'umee:mainnet' task");

// You can impersonate any Ethereum address
await network.provider.request({ method: "hardhat_impersonateAccount",  params: ["0xb1adceddb2941033a090dd166a462fe1c2029484"]});

const signer = await ethers.provider.getSigner("0xb1adceddb2941033a090dd166a462fe1c2029484")

// ERC20 token DAI Mainnet instance
const DAI = await contractGetters.getIErc20Detailed("0x6B175474E89094C44Da98b954EedeAC495271d0F");

// Approve 100 DAI to LendingPool address
await DAI.connect(signer).approve(lendingPool.address, ethers.utils.parseUnits('100'));

// Deposit 100 DAI
await lendingPool.connect(signer).deposit(DAI.address, ethers.utils.parseUnits('100'), await signer.getAddress(), '0');

Interact with Umee in Mainnet via console (NOT DEPLOYED ON MAINNET YET)

You can interact with Umee at Mainnet network using the Hardhat console, in the scenario where the frontend is down or you want to interact directly. You can check the deployed addresses at https://docs.aave.com/developers/deployed-contracts.

Run the Hardhat console pointing to the Mainnet network:

docker-compose run contracts-env npx hardhat --network main console

At the Hardhat console, you can interact with the protocol:

// Load the HRE into helpers to access signers
run("set-DRE")

// Import getters to instance any Aave contract
const contractGetters = require('./helpers/contracts-getters');

// Load the first signer
const signer = await contractGetters.getFirstSigner();

// Lending pool instance
const lendingPool = await contractGetters.getLendingPool("0x7d2768dE32b0b80b7a3454c06BdAc94A69DDc7A9");

// ERC20 token DAI Mainnet instance
const DAI = await contractGetters.getIErc20Detailed("0x6B175474E89094C44Da98b954EedeAC495271d0F");

// Approve 100 DAI to LendingPool address
await DAI.connect(signer).approve(lendingPool.address, ethers.utils.parseUnits('100'));

// Deposit 100 DAI
await lendingPool.connect(signer).deposit(DAI.address, ethers.utils.parseUnits('100'), await signer.getAddress(), '0');
