Developer Checklist: Keeping User Funds Safe in Self-Custodial Systems 🔒
When building in the Web3 space, security isn't an afterthought—it's the entire foundation. If you are developing application infrastructure or working with smart contract routers, keep these technical rules in mind:
1️⃣ Private Key Isolation: Ensure that your user's seed phrases and private keys remain strictly client-side. The backend database should never store or see plaintext credentials.
2️⃣ API Key Rotation: Never commit your production or analytics API keys to public code repositories. Utilize environment variables (.env) to isolate them.
3️⃣ Slippage & Expiry Rules: Always configure solid deadline parameters on router interactions to shield transactions from front-running or failure due to sudden network adjustments.
True decentralization means keeping the control entirely in the user's hands. Stay secure out there, fellow builders! 💻🦾
