InfraredVault

This guide will show you 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/BERA BEX 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 and stake them

/**
 * @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 *** ///
}
