InfraredVault

How to integrate InfraredVault into your platform.

This product is attractive to protocols looking to retain Berachain and Infrared incentives when integrating various LP tokens, ie HONEY/WBERA LP tokens. It is important that protocols maximize these efficiencies to ensure the best possible yield for their users. This integration looks at a contract that stakes liquidity receiving iBGT and HONEY.

Steps

1. Install the required contracts

Terminal

forge install github.com/infrared-dao/infrared-contracts.git

2. Import the required contracts

import {InfraredVault} from "@core/InfraredVault.sol";
import {IERC20, SafeERC20} from "@core/MultiRewards.sol";
import {IInfraredVault} from "@interfaces/IInfraredVault.sol";

3. Set the relevant addresses in storage

/**
 * @notice Construct the ExampleLPVaultIntegration contract.
 * @param lpVault address The address of the LP token vault.
 * @param lpToken address The address of the LP token.
 * @param ibgtVault address The address of the iBGT vault.
 * @param ibgtToken address The address of the iBGT token.
 */
constructor(address lpVault, address lpToken, address ibgtVault, address ibgtToken) {
    _lpVault = InfraredVault(lpVault);
    _lpToken = IERC20(lpToken);
    _ibgtVault = InfraredVault(ibgtVault);
    _ibgtToken = IERC20(ibgtToken);
    _lpToken.approve(address(_lpVault), type(uint256).max);
}

4. Allow users to deposit LP tokens

/**
 * @notice Deposit LP tokens to the vault.
 * @param amount uint256 The amount of LP tokens to deposit.
 */
function deposit(uint256 amount) external {
    /// require that the user has approved the contract to spend their LP tokens.
    _lpToken.safeTransferFrom(msg.sender, address(this), amount);

    /// deposit the LP tokens to the vault.
    _lpVault.stake(amount);

    /// *** Additional logic can be added here *** ///
}

5. Claim rewards from the vault

/**
 * @notice Claim rewards from the vault.
 */
function claimRewards() external {
    /// claim the rewards from the vault.
    _lpVault.getReward();

    /// *** Additional logic can be added here *** ///
}

6. Withdraw LP tokens from the vault

/**
 * @notice Withdraw LP tokens from the vault.
 * @param amount uint256 The amount of LP tokens to withdraw.
 */
function withdraw(uint256 amount) external {
    /// withdraw the LP tokens from the vault.
    _lpVault.withdraw(amount);

    /// transfer the LP tokens to the user.
    _lpToken.safeTransfer(msg.sender, amount);

    /// *** Additional logic can be added here *** ///
}

    function stakeIBGT() external {
        uint256 balance = _ibgtToken.balanceOf(address(this));
        if (balance > 0 ) {
            /// deposit the iBGT tokens to the vault.
            _ibgtVault.stake(balance);
        } else revert ("No iBGT tokens to stake");
