Integrating MultX for Cross-Chain Staking & Swaps

Now, we’ll enhance the LITHO MultX Protocol with: ✅ Cross-Chain Staking (Stake LITHO on One Chain, Earn Rewards on Another) ✅ Cross-Chain Token Swaps (Bridge LITHO & Other Tokens Securely)

---

1. How MultX Facilitates Cross-Chain Staking & Swaps

MultX uses multi-validator schemes to securely process transactions across chains.

Cross-Chain Staking Flow

1. User stakes LITHO on Blockchain A.

2. Validators detect and verify the staking event.

3. Relayer forwards staking proof to Blockchain B.

4. Staker earns rewards on Blockchain B.

Cross-Chain Swap Flow

1. User sends tokens to a bridge contract on Blockchain A.

2. Validators independently sign and approve the transaction.

3. Once 2 out of 3 validators confirm, relayer executes the transaction on Blockchain B.

4. User receives the equivalent token on Blockchain B.

---

2. Implementing Cross-Chain Staking with MultX

We will create a staking contract that:

● Accepts LITHO tokens on one chain.

● Sends staking proof via MultX.

● Rewards the user on another chain.

2.1 Deploy the Staking Smart Contract

CrossChainStaking.sol

Solidity

// SPDX-License-Identifier: MIT
pragma solidity ^0.8.0;
import "@openzeppelin/contracts/token/ERC20/IERC20.sol";
contract CrossChainStaking {
    IERC20 public lithoToken;
    address public multxRelayer;
    mapping(address => uint256) public stakedAmount;
    mapping(address => uint256) public rewardAmount;
    event Staked(address indexed user, uint256 amount);
    event RewardsUpdated(address indexed user, uint256 reward);
    event Claimed(address indexed user, uint256 amount);
 
    constructor(address _lithoToken, address _multxRelayer) {
        lithoToken = IERC20(_lithoToken);
        multxRelayer = _multxRelayer;
    }
     function stake(uint256 amount) public {
        require(amount > 0, "Amount must be greater than zero");
 
        lithoToken.transferFrom(msg.sender, address(this), amount);
        stakedAmount[msg.sender] += amount;
       
        emit Staked(msg.sender, amount);
 
        // Send staking data to MultX relayer for cross-chain processing
        (bool success, ) = multxRelayer.call(abi.encodeWithSignature("sendStakingData(address,uint256)", msg.sender, amount));
        require(success, "MultX relayer failed");
    }
        function updateRewards(address user, uint256 reward) public {
        require(msg.sender == multxRelayer, "Only MultX relayer can call this");
        rewardAmount[user] += reward;
        emit RewardsUpdated(user, reward);
    }
    function claimRewards() public {
        uint256 reward = rewardAmount[msg.sender];
        require(reward > 0, "No rewards available");
 
        rewardAmount[msg.sender] = 0;
        lithoToken.transfer(msg.sender, reward);
       
        emit Claimed(msg.sender, reward);
    }
}

2.2 MultX Validator Role in Cross-Chain Staking

MultX validators listen for staking events, sign them, and relay the event to the destination chain.

Modify the MultX Relayer Logic

Instead of swapping tokens, MultX validators:

1. Monitor staking events.

2. Sign staking transactions & forward them to the relayer.

3. Relayer executes rewards distribution on Blockchain B.

---

2.3 Integrate Cross-Chain Staking in React

Modify App.js to interact with the staking contract.

Update App.js to Handle Staking

javascript

const STAKING_CONTRACT = "0xYourStakingContract";
const stakingAbi = [
    "function stake(uint256 amount) public",
    "function claimRewards() public",
    "function rewardAmount(address user) public view returns (uint256)"
];

const [stakedAmount, setStakedAmount] = useState(0);
const [rewards, setRewards] = useState(0);
 
const checkRewards = async () => {
    const { provider, signer } = await connectWallet();
    const contract = new ethers.Contract(STAKING_CONTRACT, stakingAbi, provider);
    const reward = await contract.rewardAmount(signer.getAddress());
    setRewards(ethers.utils.formatEther(reward));
};
const stakeTokens = async (amount) => {
    const { signer } = await connectWallet();
    const contract = new ethers.Contract(STAKING_CONTRACT, stakingAbi, signer);
    await contract.stake(amount);
    toast.success(`Staked ${amount} LITHO!`);
};

Modify UI to Show Staking & Rewards

jsx

<TextField label="Stake Amount" onChange={(e) => setStakedAmount(e.target.value)} />
<Button variant="contained" onClick={() => stakeTokens(stakedAmount)}>Stake LITHO</Button>
 
<Typography variant="h6">Your Staking Rewards: {rewards} LITHO</Typography>
<Button variant="contained" onClick={checkRewards}>Check Rewards</Button>
<Button variant="contained" onClick={() => stakeTokens(stakedAmount)}>Claim Rewards</Button>

3. Implementing Cross-Chain Token Swaps with MultX

MultX will facilitate secure token swaps between chains.

3.1 Deploy Cross-Chain Swap Smart Contract

solidity

// SPDX-License-Identifier: MIT
pragma solidity ^0.8.0;
 
import "@openzeppelin/contracts/token/ERC20/IERC20.sol";
 
contract CrossChainSwap {
    IERC20 public tokenA;
    IERC20 public tokenB;
    address public multxRelayer;
    
    event SwapInitiated(address indexed user, uint256 amount, address destination);
    event SwapCompleted(address indexed user, uint256 amount);
 
    constructor(address _tokenA, address _tokenB, address _multxRelayer) {
        tokenA = IERC20(_tokenA);
        tokenB = IERC20(_tokenB);
        multxRelayer = _multxRelayer;
    }
    function initiateSwap(uint256 amount, address destination) public {
        require(amount > 0, "Amount must be greater than zero");
 
        tokenA.transferFrom(msg.sender, address(this), amount);
        emit SwapInitiated(msg.sender, amount, destination);
 
        // Send swap data to MultX relayer
        (bool success, ) = multxRelayer.call(abi.encodeWithSignature("sendSwapData(address,uint256,address)", msg.sender, amount, destination));
        require(success, "MultX relayer failed");
    }

    function completeSwap(address user, uint256 amount) public {
        require(msg.sender == multxRelayer, "Only MultX relayer can call this");
        tokenB.transfer(user, amount);
        emit SwapCompleted(user, amount);
    }
}

    "function completeSwap(address user, uint256 amount) public"
];
const swapTokens = async (amount, destination) => {
    const { signer } = await connectWallet();
    const contract = new ethers.Contract(SWAP_CONTRACT, swapAbi, signer);
    await contract.initiateSwap(amount, destination);
    toast.success(`Swap initiated for ${amount} tokens to ${destination}`);
};

Modify UI for Swaps

jsx

<TextField label="Swap Amount" onChange={(e) => setStakedAmount(e.target.value)} />
<TextField label="Destination Address" onChange={(e) => setRecipient(e.target.value)} />
<Button variant="contained" onClick={() => swapTokens(stakedAmount, recipient)}>Initiate Swap</Button>

    // Convert data into tensors
    const xs = tf.tensor2d(inputSwaps);
    const ys = tf.tensor1d(outputRoutes, "float32");
// Create AI model
    const model = tf.sequential();
    model.add(tf.layers.dense({ units: 3, inputShape: [3], activation: "relu" }));
    model.add(tf.layers.dense({ units: 1, activation: "linear" }));

    model.compile({ optimizer: "adam", loss: "meanSquaredError" });
 
    // Train the model
    await model.fit(xs, ys, { epochs: 50 });
 
    // Predict the best swap route
    const prediction = model.predict(tf.tensor2d([[amountIn, 0.005, 2]]));
