Crypto wallets, whether hardware or software, are an essential part of the blockchain ecosystem. But wallet transactions rely on RPC providers. These are often closed-source centralized companies who can view and store users’ data and metadata, well beyond what is available on chain. This completely negates attempts to make web3 trustless and decentralized.

Strengthening security and data privacy when sending transactions is the next evolution for popular wallets.

Developed for crypto wallets, RPCh uses the HOPR protocol to protect users’ assets and data. It obscures the source of your interactions with the blockchain from all intermediaries and observers. Completely closing this data leak and making your web3 browsing truly private. 

Following several proof-of-concept integrations last October, RPCh has gone live this February at ETH Denver with a full integration into BlockWallet. 

In contrast to non-private RPC providers, which all send data via HTTP(S) / WS, the HOPR protocol requires a dedicated integration of our SDK, which enables your wallet to "speak HOPR" instead of HTTP.


Join us in Istanbul this April and protect your users’ data with a free integration of RPCh.



the first private RPC provider into Wallets

Two options how to integrate RPCh into a wallet in Istanbul:


Hacker Track

We’re looking to sponsor Hackers to integrate RPCh within wallets. The sponsorship includes paid-for accommodation, beverages & food for the entire event.

Successful applicants should consider:

  • The wallet you choose to integrate RPCh with (we have a list for you, but feel free to suggest)

  • Ease of integration (do they use ethers.js / web3.js)

  • Compliance with the wallets testing and deployment standards (make sure it's working seamlessly)

  • UI is not needed as you will send a PR directly to the wallet to add or replace Gnosis chain with Gnosis chain over RPCh

  • Your hack will be used in LIVE production after the wallet accepts your PR!


Teams of ​successful PRs will receive rewards in HOPR token. Your team will also be offered to work on similar bounties, after the hackathon.​

​Fill out the form, and we’ll be in touch shortly.
