Joint Venture Enables Direct GPU Mining of Wry Token

Press Release, May 12, 2021

Joint Venture

The daPool Mining Pool and the Ycash Foundation have entered into a joint venture to enable GPU miners from around the world to mine Wry, the new DeFi token on Binance Smart Chain recently launched by the Ycash Foundation.

Pursuant to the joint venture, daPool has integrated Wry into their proprietary Ycash mining pool software. Starting today, GPU miners can mine Ycash via daPool’s Ycash mining pool but get paid out in Wry instead of Ycash. …

In addition to representing wrapped Ycash, Wry will power a lending platform for using ERC-20 tokens as collateral for stablecoin loans

I am excited to announce the official launch of the Wry token on Binance Smart Chain (BSC).

Since the open beta of Wry on BSC began at the end of February, Ycash users have moved nearly 100,000 Ycash coins (aka YEC) over to WRY. It is already easy to buy or sell Wry on PancakeSwap, where Wry liquidity continues to grow.

In this article, I will explain what Wry is, how Wry will be useful, and how you can get Wry right now.

Wry is Wrapped Ycash, and More

What is Wry? The name Wry derives from the term Wrapped Ycash…

The Ycash Foundation will launch ERC-20 tokens representing wrapped Ycash on both Ethereum and Binance Smart Chain

I am excited to announce that the Ycash Foundation will launch ERC-20 tokens representing “wrapped” Ycash on both Ethereum and Binance Smart Chain by January 15, 2021. These tokens will enable Ycash holders to use Ycash with Decentralized Finance (DeFi) applications like Uniswap on Ethereum and PancakeSwap on Binance Smart Chain.

The tokens will be centrally managed by the Ycash Foundation. Specifically, the Ycash Foundation will handle the minting and burning of the tokens, as well as the custody of the underlying Ycash coins. …

A regrettable pun, but a legitimate question nonetheless

This is the first in a series of articles that will discuss the brief history, current status, and future of the Ycash digital currency.

Shortly after Ycash was announced in April of 2019, it didn’t take long for us to hear the first (but certainly not the last) utterance of the regrettable pun, “Why Ycash?” Pun aside, it’s a legitimate question: In a world with thousands of digital currencies — including Bitcoin, Zcash, and several code forks of Zcash— why launch Ycash?

In this first article of the “Understanding Ycash” series, we’ll discuss the original motivations that led to the…

Backing up your wallet, receiving YEC, and sending YEC to a shielded address


In this article, we will show you how to get started with using YecLite, a lightweight Ycash wallet for MacOS, Linux, and Windows. We will walk you through downloading YecLite, backing up your wallet, receiving YEC into a transparent address, and then sending a portion of that YEC to a shielded address.

Note that screenshots used in this article are from the MacOS version of YecLite and may differ slightly from what you see if you are using either the Linux version or the Windows version.

[Note: The screenshots below are from an earlier version of YecLite, and will be…

Enjoy the power and privacy of shielded Ycash transactions on your personal computer, without needing to download the entire Ycash blockchain


The Ycash Foundation is excited to announce the release of YecLite, a lightweight Ycash wallet that fully supports shielded Ycash transactions on computers running MacOS, Linux, or Windows. Download YecLite now:

Prior to YecLite, the only way to send or receive shielded Ycash transactions was to use ycashd or YecWallet, both of which require a full copy of the Ycash blockchain (currently over 22 GB in size). With the release of YecLite, it is now dramatically easier to get started with sending and receiving shielded Ycash transactions!

Published: August 15, 2019. Last updated: December 3, 2019.


This roadmap covers Ycash software development for the next several months. (It also includes projects completed between the Ycash launch on July 18, 2019 and the initial publication of this roadmap on August 15, 2019.) This roadmap is subject to change; check back here for the most up-to-date information.

During the coming months, the Ycash Foundation will fund projects in four key areas.

  1. Improvements to ycashd and YecWallet
  2. Light Wallets
  3. Merchant Tools
  4. Mining Algorithms


Below is a summary of the projects that the Ycash Foundation is funding, organized by area.

Improvements to ycashd and YecWallet

With a worldwide legion of GPUs, Ycash has launched.

A New Beginning

Twenty-four days ago — on July 18, 2019 — the Ycash/Zcash chain fork occurred. As the last block shared with Zcash was mined at 19:31:50 PDT, people around the world mining with GPUs began working on mining the first Ycash-specific block.

Five minutes and one second later, at 19:36:51 PDT, the first Ycash-specific block was mined!

This block — at block height 570,000 — is the first block that Ycash does not share with Zcash. Although the Ycash blockchain begins with the Zcash genesis block minted in October 2016, it will now continue completely independent of the Zcash blockchain, on…

Before you decide to mine or buy Ycash, some considerations

At the time of this writing, the Ycash/Zcash chain fork is less than 100 blocks away. Since the fork has not yet occurred, no one in the world has mined or bought a single YEC. Before you do so, please consider the following:

Consideration 1: The Ycash Foundation is committed to mining on commodity hardware in general, not to mining on a particular class of commodity hardware.

As stated in the initial Ycash announcement on April 11, 2019, “To be clear, our commitment is to commodity hardware in general, not to a specific type of commodity hardware, like GPUs.”


Last minute tips for increasing your security and privacy on both blockchains

After the Ycash/Zcash chain fork occurs very soon at block height 570,000, the private keys associated with your ZEC on the Zcash blockchain will also be associated with YEC on the Ycash blockchain. As a ZEC holder, if you choose to try to access your YEC, you may want to “unlink” your YEC and ZEC in certain ways for increased security and privacy.

(Before reading this post, you may want to read “A Zcash Holder’s Guide to Accessing Ycash.”)

Strategy #1: Move your ZEC to new addresses AFTER the fork.

Let’s say your ZEC is associated with a set of addresses that we’ll call Address Set M.

Steps for Strategy #1

  1. Fork occurs at block…
