RPCh is a service on top of the HOPR protocol, which routes RPC requests and responses via the HOPR network. The first of its kind and the only truly private way to make transactions in web3.

In web3, almost every transaction relies on infrastructure provided by closed-source, centralized infrastructure providers who you simply have to trust not to misuse your data. We’re talking about RPC providers like Infura/Alchemy, the engine that keeps the entire crypto rocket flying, supporting billions of RPC calls daily. But unlike the crypto system they support, they are highly centralized black boxes which are entirely closed source.
Although large players like Infura have now recognised the problem, they have yet to do anything about this gaping privacy hole. RPCh solves this by routing requests and responses via the HOPR network. Users running an RPCh entry instance can route RPC requests over the HOPR mixnet before exiting via any node running RPCh. This will obscure all the metadata associated with the RPC call, closing a major privacy loophole in web3. RPCh is the first commercially available service built on top of the HOPR protocol and a major breakthrough in web3 privacy. RPCh can run on top of existing RPCh infrastructure or our own HOPR RPC nodes.

With RPCh YOUR wallet can be more private than ever before. All of that is possible without changing any underlying logic of the wallet or blockchain. Our HOPR connector layer provides a simple drop-in replacement for the HTTP(S) connection of your current web3 provider in e.g. web3.js or ethers.js. In this way the user IP addresses remain private without much integration hassle.

RPCh Wallet Integrations (Demo)

At the Infinite Hackathon in Bogota this year, three wallets were integrated with RPCh. BlockWallet, Tally Ho! and Frame all let you use HOPR’s RPCh to completely obscure your metadata while using or even browsing web3 services. Watch the demos below to see each integration in action.

What makes RPCh unique?


Packet Mixing
for complete metadata and data privacy.
Decentralized Network
for a trustless and private solution.
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.


Every time we look under the hood of a web3 service, we find it’s leaking unacceptable amounts of data and metadata. Especially large public RPC providers who are reckless in their handling of billions of RPC calls daily. At HOPR, we knew we had to do something to address this massive privacy concern, which is why we built RPCh.

DERP – The Dumb Ethereum RPC Provider

DERP replicates an RPC provider and displays your requests in real time, highlighting the privacy pitfalls of public RPC providers. Many of today’s DeFi services leak identifying metadata, even if you don’t make a transaction. This shows how vital a transport layer privacy solution like HOPR will be in building web3.

HOPR hosts UX hackathon in collaboration with MetaMask

Clear and simple UX design is a fundamental part of bringing choices about privacy to users. At the first ever crypto UX hackathon, participants designed an implementation of the HOPR protocol as a Snap within the MetaMask wallet. These designs were used to inform implementation decisions for later hackathons and internal development of RPCh.

First RPCh implementation during the Infinite Hackathon, Bogota, Colombia

At the Infinite Hackathon, we challenged hackers to integrate RPCh with live crypto wallets of their choice. This was the first attempt to implement RPCh and was a resounding success with three seamless integrations: BlockWallet, Tally Ho! and Frame.

RPCh goes live!

We have officially launched RPCh and dedicated a new sub-team within HOPR to its future development and integration. This commitment comes with exciting developments, from follow-up events to new partnerships. Keep an eye out, as the coming months will be eventful for both HOPR and RPCh!
