🕳️Hole Cash

The ultimate privacy fortress in crypto!

Blockchains are marvelous pieces of system technology, allowing for trustless, secure, and efficient transfer of data across countless nodes. This is all possible because the data is distributed, making it verifiable, and transparent like a beautiful diamond. Yet, while this transparency empowers the system as a whole, it comes at a great price to the individual user — the lack of anonymity.

On almost all the most populated blockchains, every transaction, every wallet address, every piece of on-chain data is visible to anyone who wishes to see it. That means that like the blockchain, you as an individual are exposed; naked, with your assets written all over you like permanent tattoos. So what can someone do if they wanted privacy? If they wanted to be anonymous? To not be forced to live under a microscope…

Well, if they want those things on Arbitrum, then they’re going to need Hole Cash.

Hole is a Arbitrum-deployed new generation of anonymous hub. It uses various cryptographic methods, including implementations of zero-knowledge(zkSnarks) proofs to achieve privacy functionality. So we’ve taken something that works, to regain their right to anonymity, customized it in Hole for the current DeFi landscape, and brought it to Arbitrum.
