Security

This section expands on Tribe's defense‑in‑depth smart contract protections—reentrancy guards, supply limits, slippage checks, LP lock logic, fee enforcement, and bonding‑curve constraints. It explains how these mechanisms work together to ensure fairness, prevent manipulation, eliminate rug‑pull vectors, and maintain a trust‑minimized environment across all meme tokens launched on Tribe.

Security Philosophy​

Tribe implements a comprehensive security model that protects users, creators, and the platform itself. Our defense-in-depth approach ensures multiple layers of protection work together to create a secure, fair, and trustless environment.

Security Features​

Reentrancy Guards​

All state-changing functions are protected with reentrancy guards:

modifier nonReentrant() {
    require(!locked, "ReentrancyGuard: reentrant call");
    locked = true;
    _;
    locked = false;
}

Protected Functions:

  • createToken()
  • buyTokens()
  • sellTokens()
  • addComment()
  • migrateLiquidity()

Purpose: Prevents reentrancy attacks where malicious contracts could exploit state changes during execution.

Creator Buy Limits​

Maximum Purchase Limit:

  • Creator limited to 20% of curve supply (140M tokens)
  • Prevents creator from dominating the curve
  • Ensures fair distribution to community

Implementation:

if (msg.sender == tokenInfo.creator) {
    require(
        tokenInfo.creatorBought + tokensOut <= maxCreatorAmount,
        "Creator limit exceeded"
    );
}

Purpose: Prevents manipulation and ensures fair token distribution.

Unlock Enforcement​

Unlock Requirement:

  • Creator must buy 2% of total supply (20M tokens) to unlock
  • Tokens remain locked until threshold met
  • Public trading blocked during locked state

Validation:

if (!tokenInfo.isUnlocked) {
    require(
        msg.sender == tokenInfo.creator,
        "Token is locked"
    );
    // Check if 2% threshold reached
    if (tokenInfo.creatorBought >= unlockThreshold) {
        tokenInfo.isUnlocked = true;
    }
}

Purpose: Eliminates rug-pull vectors by requiring creator commitment.

Valid Token Checks​

All functions validate token existence:

require(
    tokens[token].creator != address(0),
    "Token does not exist"
);

Applied to:

  • Buy/sell functions
  • Comment functions
  • Migration functions
  • View functions

Purpose: Prevents interactions with non-existent or invalid tokens.

Exact Fee Checks​

Fee calculations are verified:

uint256 fee = (amount * TREASURY_FEE_BPS) / 10000;
require(fee == expectedFee, "Fee calculation error");

Fee Rate: 2% (200 basis points)

Purpose: Ensures fee calculations are correct and prevents fee manipulation.

Router Validation​

Router address validated before use:

require(router != address(0), "Router not set");
require(router.code.length > 0, "Invalid router");

Purpose: Prevents migration to invalid or malicious routers.

Slippage Protection​

All trading functions include slippage protection:

Buying:

require(tokensOut >= minTokensOut, "Slippage too high");

Selling:

require(trustOut >= minTrustOut, "Slippage too high");

Purpose: Protects users from unexpected price movements during transactions.

LP Lock Logic​

Permanent LP Lock:

  • LP tokens remain permanently locked in contract
  • Cannot be withdrawn by anyone
  • Prevents rug pulls after migration

Implementation:

// LP tokens stored in contract
// No withdrawal function
// Permanently locked

Purpose: Guarantees liquidity remains in DEX pair, preventing rug pulls.

Supply Limits​

Bonding Curve Constraints:

  • Maximum 700M tokens available via curve
  • 300M tokens held for liquidity
  • Total supply fixed at creation

Enforcement:

require(
    curveSupply <= maxCurveSupply,
    "Curve supply exceeded"
);

Purpose: Maintains predictable token economics and prevents supply manipulation.

Defense-in-Depth Architecture​

Layer 1: Input Validation​

  • All inputs validated before processing
  • Type checking and range validation
  • Address validation

Layer 2: State Checks​

  • Token existence verification
  • State validation (locked/unlocked/completed)
  • Supply limit enforcement

Layer 3: Access Control​

  • Public functions for trading
  • Admin-only for critical functions
  • Creator-specific unlock logic

Layer 4: Economic Protections​

  • Slippage protection
  • Fee enforcement
  • Supply limits
  • Creator limits

Layer 5: Migration Safety​

  • Router validation
  • LP permanent lock
  • Automatic migration only
  • No manual intervention

Security Considerations​

Frontend Security​

Best Practices:

  • Validate all user inputs
  • Check token state before transactions
  • Implement proper error handling
  • Use secure Web3 providers
  • Verify contract addresses

Example:

// Always validate before transaction
const tokenInfo = await contract.getTokenInfo(tokenAddress);
if (!tokenInfo.isUnlocked) {
    throw new Error('Token is locked');
}

Smart Contract Security​

Recommendations:

  • Use audited contracts
  • Implement comprehensive testing
  • Review code before deployment
  • Use multisig for admin functions
  • Monitor for suspicious activity

Treasury Security​

Treasury Management:

  • Use multisig wallet
  • Regular audits
  • Monitor fee collection
  • Secure key management

Router Security​

Router Considerations:

  • Use verified router contracts
  • Verify router address before setting
  • Test router interactions
  • Monitor router updates

Common Vulnerabilities (Prevented)​

Trust-Minimized Environment​

Tribe's security model creates a trust-minimized environment where:

  • No Trust in Creators - Unlock requirements and limits prevent abuse
  • No Trust in Platform - LP tokens permanently locked
  • No Trust in Users - Slippage protection and validation
  • No Trust in Routers - Validation and verification required
