Bridge Contracts

Managing the private pools and coordinating swapping or transferring assets between chains

Bridge Contracts:

• Bridge contracts facilitate the transfer of tokens between different chains.

• They coordinate the locking, communication, and releasing of tokens across chains.

• Bridge contracts interact with private pools on both chains to ensure seamless transfers.

Bridge Contract Sample

contract BridgeContract {
    mapping(address => address) public privatePools;
    mapping(unit256 => address) public bridges;
    mapping(unit256 => SendRequests) public sendRequests;
    
    struct SendReqMessage {
    }
    
    struct AskForFundReqMessage {
    }
    
    struct AskForFundResMessage {
    }

    event TokensLocked(address indexed user, uint256 amount, address indexed to);

    constructor(address[] memory _privatePools, address[] memory_bridges) {
        privatePools = _privatePools;
        bridges = _bridges;
    }

    function sendMessageXChainTo(address srcBridge, address dstBridge, address token, uint256 amount, address to) external {
        require(IPrivatePoolA(privatePoolA).balanceOf(msg.sender) >= amount, "Insufficient balance");
        // Add logic to send the request message of the transferring tokens 
        // to the target bridge address on the destination chain
    }
    
    function sendMessageTo(address from, address token, uint256 amount, address to) external {
        // Add logic to send the request message of the transferring tokens 
        // from a source chain to the address on the current chain
    }

    function broadcastAskForFundReq(address from, uint8 sourceChainId, address token, uint256 amount, address to) internal {
        // Add logic to broadcast the request message of the transferring tokens 
        // from a source chain to the address on the current chain to all private pools
    }
    
    function handleAskForFundRes(address from, uint8 sourceChainId, address token, uint256 amount, address to) external {
        // Add logic to handle the response message of asking for fund 
        // from a valid private pool
    }
    
    
}

interface IBridge {
    function sendMessageXChainTo(address token, uint256 amount, uint8 desChainId, address to) external;
    function sendMessageTo(address from, uint8 sourceChainId, address token, uint256 amount, address to) external;
    function broadcastAskForFundReq(address from, uint8 sourceChainId, address token, uint256 amount, address to) internal;
    function handleAskForFundRes(address privatePool) internal;
