What you'll find here

Solidity Smart Contract template for creating your own contract in the Brownie framework.

Interfaces for some of the most used DeFi protocols on ethereum mainnet.

Sample test suite that runs on mainnet fork.

How does it work for the User

Let's say Alice holds 100 DAI and wants to start earning yield % on them.

For this Alice needs to DAI.approve(vault.address, 100).

Then Alice will call vault.deposit(100).

Vault will then transfer 100 DAI from Alice to itself, and mint Alice the corresponding shares.

Alice can then redeem those shares using yVault.withdrawAll() for the corresponding DAI balance.
