Finally, privacy for your user’s wallets

Despite millions of users worldwide, today’s wallets often leak user IP addresses and other types of metadata.

The problem

Crypto wallets are an essential part of the blockchain ecosystem. But wallet transactions rely on RPC providers, centralized companies who can view and store users’ data and metadata, well beyond what’s available on chain.

We need to make web3 trustless, and that means eliminating the ability to harvest IP addresses and other metadata. This provides security and privacy for users and removes exploit risks for wallets.

Attack vectors

Metamask linkability

RPC providers can be pressured by third parties to disclose user data or even censor particular users or transactions.

NFT frontrun

RPC providers can harvest users’ data and metadata and exploit them for gain, including harmful new kinds of MEV.

Dex Mev

Decentralized web3 RPC providers can actually be LESS private than their centralized equivalents. When anyone can host an RPC endpoint, it’s crucial that users’ metadata is protected.

The solution

RPCh helps both users and wallets by removing the ability to harvest data. Integration is simple thanks to our SDK and user IP addresses are hidden. Users don’t notice any difference or pay any extra.

What makes RPCh unique?

Two arrows blending represeting Packet Mixing

Packet Mixing

For complete metadata and data privacy.

For a trustless and private solution.

Proof of relay

To securely incentivize node runners.

The combination of these 3 USPs creates a stronger privacy solution than TOR or any VPN.

1. Proof-of-Relay

HOPR’s unique proof-of-relay mechanism means every node runner is incentivized to correctly relay data in exchange for HOPR tokens. Anyone can run a HOPR node to earn HOPR tokens and contribute to online data privacy.

2. Decentralized Network

The HOPR network is a decentralized incentivized mixnet, ensuring complete data and metadata privacy for everyone who uses it. Data is sent via multiple hops, so no-one but the sender and receiver know the origin, destination, or content of a data transfer.

3. Packet Mixing

Each node combines multiple packets from different messages, occasionally delaying certain packets and adding them to future mixing cycles. These are transferred across the mixnet as indistinguishable bundles, separated and mixed at every node for complete privacy.

FAQ

What does RPCh solve?

Faq arrow

Ethereum RPC providers can see IP addresses and other metadata of Ethereum users. That is a liability for users, wallets and RPC providers alike.

What is RPCh?

Faq arrow

An RPC provider that works exclusively via the HORP network and is thus fully metadata private on the transport layer.

How does RPCh work?

Faq arrow

RPCh uses the following features to serve as a completely private RPC provider:

  • 1. Thin wallet connector to relay RPC requests & responses via the HOPR network instead of HTTP(S).

  • 2. HOPR exit node connector to relay RPC requests & responses to/from a standard Ethereum RPC endpoint (e.g. an Ethereum execution layer client).

  • 3. Out-of-the-box ability to verify the integrity of RPC responses.

  • 4. Highly scalable, available & performant Ethereum node infrastructure that is used by RPCh clients.

How much does Integration cost?

Faq arrow

The integration & usage for every crypto wallet of RPCh is easy and seamless. Our team will support the integration with the standard SDK. It’s as simple as exchanging your current RPC provider with any other RPC provider. Integration is free. Monthly costs depend on your usage. Prices are competitive.

What is the difference between RPCh and HOPR?

Faq arrow

RPCh is a product made possible by building on top of the HOPR protocol.

What is the HOPR network?

Faq arrow

The HOPR network is the (not so) secret sauce that makes RPCh metadata private. HOPR is an incentivized mixnet that is much more private than a VPN or even Tor. Thanks to its proof-of-relay mechanisms, the mixnode operators get paid for forwarding packets in the decentralized HOPR network and thus provide privacy for both senders and receivers. -> HOPRnet.org/protocol
