Smart Contract Functionality

The Eduena contract in src/Eduena.sol

Functions

• deposit(uint256 amount): Allows users to deposit a specified amount of USDe tokens and it immediately staked to sUSDe. The equivalent amount of Eduena tokens (EDN) is minted and assigned to the user.
• withdraw(uint256 shares): Allows users to withdraw a specified amount of Eduena tokens (EDN). The equivalent amount of sUSDe tokens is transferred back to the user.
• distribute(address recipient, uint256 shares): Distributes a specified amount of yield to a recipient.
• accrueYield(): Updates the yield based on the current asset value in USDe.

Events

• DepositAndStake(address indexed user, uint256 amount): Emitted when a deposit is made and staked.
• Withdraw(address indexed recipient, uint256 amount): Emitted when a withdrawal is made.
• Distribute(address indexed recipient, uint256 amount): Emitted when yield is distributed.
• YieldAccrued(uint256 newAssetValueInUSDe, uint256 yield): Emitted when the yield is updated.

Errors

• InsufficientBalance(): Thrown when a user tries to withdraw more than their balance.
• DepositAmountZero(): Thrown when a deposit amount is zero.
• ExceedsUnclaimedYield(): Thrown when the amount exceeds the unclaimed yield.

Testing

The EduenaTest contract in test/Eduena.t.sol includes tests for the deposit and withdrawal functionalities.

Example Test Functions

function testDepositAndWithdraw() public {
    // Test deposit and withdrawal functionality
}

function testAccrueYield() public {
    // Test yield accrual functionality
}

Setting Up Environment Variables

To run the tests, you need to set up the following environment variables in a .env file:

MAINNET_RPC_URL=https://eth-mainnet.g.alchemy.com/v2/account_key_xxx
FORK_BLOCK_NUMBER=21272472

Running the Tests To run the tests using Foundry, use the following command:

forge test

Deployment

The Eduena contract is deployed on Tenderly for testing purposes.

Setting Up RPC for Virtual Testnet

To interact with the Eduena contract on the virtual testnet, you need to configure the RPC settings in your wallet or MetaMask.

MetaMask Configuration

1. Open MetaMask and go to the network dropdown at the top.

2. Select "Add Network" and fill in the following details:

   • Network Name: Tenderly
   • New RPC URL: https://virtual.mainnet.rpc.tenderly.co/7f501e58-b80d-4397-9031-146391be0952
   • Chain ID: 1 (or the appropriate chain ID for your testnet)
   • Currency Symbol: ETH
   • Block Explorer URL: (optional) https://explorer.tenderly.co

3. Click "Save" to add the network.

Wallet Configuration

If you are using a different wallet, refer to its documentation for adding a custom RPC network. Use the same details as provided above for MetaMask.

Once configured, you can connect your wallet to the Eduena testnet and interact with the deployed contract.

Fund account

Fund VETH for gas fee:

curl --location 'https://virtual.mainnet.rpc.tenderly.co/fad38b2e-0b26-4b16-b2c3-c24ac629af36' \
--header 'Content-Type: application/json' \
--data '{
  "jsonrpc": "2.0",
  "method": "tenderly_setBalance",
  "params": [["USER_WALLET_ADDRESS"], "0x152d02c7e14af6000000"]
}'

Fund your account with USDe for testing Eduena deposits. The first parameter is the USDe contract address, the second parameter is your wallet address, and the third parameter is a 32-byte hash representing the token amount in wei. The example below sets a balance of $100,000 USDe to the user's address.

curl --location 'https://virtual.mainnet.rpc.tenderly.co/fad38b2e-0b26-4b16-b2c3-c24ac629af36' \
--header 'Content-Type: application/json' \
--data '{
    "jsonrpc": "2.0",
    "method": "tenderly_setErc20Balance",
    "params": [
        "0x4c9EDD5852cd905f086C759E8383e09bff1E68B3",
        "USER_WALLET_ADDRESS",
        "0x152d02c7e14af6000000"
    ]
}'
