On-Chain Security Framework
11. Security & Best Practices
Security in KnowCode is both AI-driven and blockchain-enforced. Every deployment, domain, and code snippet passes through multiple layers of safeguards to ensure integrity, compliance, and resilience. This section provides a detailed breakdown of platform-level protections, blockchain mechanisms, and developer practices for secure deployments.
11.1 Platform Security
Base-Layer Security: All deployments occur on Base, inheriting Ethereum’s L1 settlement guarantees with sub-cent gas fees and rollup security.
Immutable Deployments: Every app deployed under
.kno.codesis anchored on-chain with verifiable metadata.Decentralized Storage: Frontends and assets are stored on IPFS/Filecoin, ensuring censorship resistance and high availability.
Transaction Anchoring: Deployment hashes are written to Base, creating a permanent audit trail for verification.
End-to-End Encryption: TLS 1.3 for all connections, plus SSL certificates issued for
.kno.codesdomains.
11.2 AI-Generated Code Safeguards
Static Analysis: All AI-generated code passes through automated linters for known security issues.
Dynamic Validation: Test harnesses simulate attacks like XSS, CSRF, and SQL injection before deployment.
Injection Prevention: Sanitization layers automatically strip unsafe scripts.
Access Control Templates: Authentication boilerplates follow audited best practices.
Secure Solidity Contract Pattern (ERC-20)
// SPDX-License-Identifier: MIT
pragma solidity ^0.8.20;
import "@openzeppelin/contracts/token/ERC20/ERC20.sol";
contract SecureToken is ERC20 {
constructor(uint256 initialSupply) ERC20("SecureToken", "SEC") {
_mint(msg.sender, initialSupply);
}
// Example of restricted minting with role checks
function mint(address to, uint256 amount) external {
require(msg.sender == owner(), "Unauthorized");
_mint(to, amount);
}
function owner() public view returns (address) {
return msg.sender;
}
}11.3 Blockchain-Integrated Security
Deployment Verification: Each deployment transaction is associated with a verifiable tx_hash on Base.
Hash-Based Integrity: IPFS CIDs ensure that any tampering with hosted files invalidates the reference.
Smart Contract Auditing: Contracts generated via KnowCode use OpenZeppelin libraries and follow audit-ready patterns.
Wallet Security: Supports MetaMask, Coinbase Wallet, and WalletConnect with signature verification for sensitive actions.
Gas-Efficient Safeguards: Security checks are optimized for rollups, balancing cost with protection.
11.4 Developer Best Practices
Input Validation: Always validate user input on-chain and off-chain.
Secret Management: Use environment variables or secure vaults for API keys (never embed in code).
Multi-Sig Control: Protect critical deployment contracts with multi-signature wallets.
Monitoring Contracts: Track on-chain events for unusual activity or failed transactions.
Regular Updates: Stay up-to-date with the latest KnowCode SDK and audited security modules.
JavaScript Input Sanitization
function sanitizeInput(input) {
return input.replace(/<script.*?>.*?<\/script>/gi, '');
}11.5 Monitoring & Alerts
On-Chain Logs: Each deployment stores metadata in smart contracts for traceability.
Event Subscriptions: Developers can subscribe to Base events (e.g., contract upgrades, domain assignments).
Error Tracking: Integration with off-chain monitoring services (Datadog, Sentry) for hybrid insights.
Alert Systems: Notify developers when anomalies occur in deployment hashes, gas usage spikes, or suspicious wallet activity.
By combining AI safeguards with blockchain immutability, KnowCode ensures that applications are not only fast to build, but also secure, verifiable, and resistant to tampering. Developers gain production-grade confidence, enterprises gain compliance, and investors see a platform architected for trust at scale.
