Base has operated for over 800 days without a single exploit or bridge hack, secured over $35 billion in bridged assets, and inherits Ethereum's full economic security via optimistic rollups and fraud proofs. Coinbase runs multiple high-availability nodes, and the network has achieved 99.99% uptime since launch. As long as you use official RPCs or ChainList, there is zero risk to your funds, MetaMask never exposes private keys during network addition.
• Official Sources: Always use verified endpoints from Base's site or ChainList to prevent man-in-the-middle attacks.
• Testnet Focus: Start with testnet to experiment without real value at stake.
• Security Best Practices: Enable MetaMask's security features and use hardware wallets for larger amounts.
No major incidents have been reported with this integration, but stay updated via MetaMask's blog for any advisories. MetaMask doesn't custody your funds, only you control your private keys, so the risk lies in phishing or incorrect RPCs.
