🔐 Security Overview

🔒 Access	🛡️ Guards	📊 Limits	🔍 Audits
Role-based	Reentrancy	Safety rails	External review

🎯 Purpose: Protect user funds and ensure system integrity

🔒 Principle: Defense in depth with multiple security layers

🔒 Access Control

🔒 Access Control Model

Role-Based Access

Pattern	Implementation
📜 Standard	OpenZeppelin AccessControl
🔑 Hierarchy	Admin can grant/revoke
🏷️ Granular	Per-function permissions

---

Standard Roles

Role	Purpose	Holder
DEFAULT_ADMIN_ROLE	Super admin	Multisig
ADMIN_ROLE	Admin functions	Ops team
MINTER_ROLE	Token minting	Authorized contracts
GOVERNANCE_ROLE	Governance execution	Timelock

---

Role Assignment

// Only admin can grant roles
function grantRole(bytes32 role, address account)
    public virtual onlyRole(getRoleAdmin(role));

// Role-protected function
function mint(address to, uint256 amount)
    external onlyRole(MINTER_ROLE);

Founder → Multisig Transition

Phase	Control
🔵 Launch	Founder single-sig
🟡 Transition	enableMultisig()
🟢 Operational	Multisig control

modifier onlyAuthorized() {
    if (multisigEnabled) {
        if (msg.sender != multisigWallet) revert NotAuthorized();
    } else {
        if (msg.sender != founder) revert NotAuthorized();
    }
    _;
}

---

One-Way Transition

function enableMultisig(address _multisig) external onlyFounder {
    if (multisigEnabled) revert MultisigAlreadyEnabled();
    if (_multisig == address(0)) revert InvalidAddress();
    multisigWallet = _multisig;
    multisigEnabled = true;
    emit MultisigEnabled(_multisig);
}

No way to disable once enabled.
