ArcusX Smart Escrow (Example Architecture)

⚠️ Disclaimer: The following architecture is a conceptual example of how a smart escrow system could function within ArcusX. It is not final. The actual implementation may differ significantly as we explore more advanced, modular, and scalable designs tailored to our users and ecosystem.

⚙️ Example Smart Contract Structure

Designed for EVM-compatible chains (Solidity Smart Contract), this sample illustrates how a task-based escrow system might operate.

🧱 Core Structures

solidityCopiarEditarstruct Task {
    address creator;
    address contributor;
    uint256 amount;
    Status status;
    bool creatorConfirmed;
    bool contributorConfirmed;
    bool disputed;
}

solidityCopiarEditarenum Status {
    Created,
    ProposalAccepted,
    InProgress,
    Submitted,
    Completed,
    Disputed,
    Resolved
}

---

🔑 Sample Workflow Functions

solidityCopiarEditarfunction createTask(address _moderator) external payable;
function submitProposal(uint256 _taskId) external;
function acceptProposal(uint256 _taskId, address _contributor) external;
function markAsCompleted(uint256 _taskId) external;
function confirmCompletion(uint256 _taskId) external;
function raiseDispute(uint256 _taskId) external;
function resolveDispute(uint256 _taskId, bool releaseToContributor) external onlyModerator;

🧩 Integration Notes

🔌 Frontend (Example)

• Connect with ethers.js, viem, or Web3 libraries.

• Listen to contract events to reflect lifecycle states (e.g., TaskCreated, DisputeRaised).

🛰️ Backend

• Optionally index tasks and status via The Graph.

• Notify moderators or trigger off-chain workflows via webhook/API.

---

🛡️ Security Recommendations

• Use ReentrancyGuards for state-changing + fund-moving functions.

• Implement AccessControl for trusted roles (moderators, fee manager).

• Use SafeERC20 or native token security patterns.

---

🧪 Test Environment (Suggestions)

Tool	Purpose
Hardhat	Local testing and scripts
Tenderly	Contract debugging/monitoring
Base Goerli	Testnet for staging
Mock dApp	Simulate escrow workflows
