Question: Can you recommend a Web3 relay that ensures user privacy and blocks metadata leakage?

If you're looking for a Web3 relay that you can count on to protect user privacy and prevent metadata leakage, 1RPC is a great option. It provides a single RPC endpoint to interact with a variety of blockchain networks while blocking metadata leakage and ensuring zero-tracking. It includes transaction sanitizers for real-time phishing protection, metadata removal, and customizable experience with custom API keys and protection rules. With several pricing tiers, including a free option, 1RPC is built for user privacy and ease of use in Web3 interactions.

Another good option is Oasis, a platform that's geared for fast and secure Web3 and AI applications. It's got a Privacy Layer that lets developers add privacy to dApps on any EVM network, and a Multi-Layer Architecture that lets developers run multiple parallel runtimes. With a modular design, Oasis is designed for high throughput and interoperability across different blockchain networks, and it's good for a range of use cases like decentralized AI and gaming.

If you're looking for a broader privacy solution, you might want to check out Brave, a fast and private web browser that includes private search, an integrated AI assistant and a powerful VPN to protect all your devices' network connections. Its default shields block ads, trackers and fingerprinting, so you get the strongest privacy protection available. Brave is available on multiple devices and in many languages, so it's a good tool for protecting your privacy in many parts of your life, not just Web3.
