We Are So Back
We are so back, now as ParyonUSD, with the same familiar ticker: PUSD.
We know many of you have been following along eagerly since the initial announcement, and that means a lot to us. Since our last update, we’ve used the extra time to add some additional polish and hardening across the board. Today we’re here with news that puts us on a clear path to launch.
Why the Name Change
We wanted a name that’s fully ours, something distinctive and unambiguously us. ParyonUSD (Paryon for short) gives us that, and no more name collisions with the many other things in crypto already called “Parity.”
Nothing changes about the protocol, the contracts, or how the system works; only the branding around them is new. Same team, same PUSD.
Same Mission
We set out to bring real DeFi to Bitcoin Cash: stable savings and payments, borrowing against your BCH without selling it, and earning yield through staking. That’s still exactly what we’re here to do.
Beyond the protocol itself, we want to move BCH forward as a whole. PUSD is designed to be a foundational primitive that other projects can build on, growing the CashTokens userbase and proving what’s possible on the network. Every new user who mints, stakes, or transacts with PUSD is one more person experiencing what BCH DeFi can do.
Launch Timeline
We’re committing to an April launch. PUSD will bring a decentralized stablecoin, BCH-backed borrowing, and staking yields to Bitcoin Cash for the first time. We expect PUSD to become an important primitive for BCH DeFi, serving as a building block for other projects to build on. We can’t wait to get this into your hands.
The exact date will be announced on our socials, so follow us to stay in the loop.
See You at BCH Bliss
The PUSD team will be at BCH Bliss 2026, May 15-17 in Ljubljana, Slovenia. Mathieu will be giving a talk on the journey of building PUSD: the main lessons we learned along the way, and a glimpse of what’s next. Richard will be presenting new developer tooling we built as part of the PUSD project and are making available to the wider BCH ecosystem. We’ll be on the open floor throughout the event too. If you’re attending, come say hi!
Aside: Dropping the Parity Bit
Did you know the word “parity” already has a meaning in Bitcoin jargon? When BTC implemented Schnorr signatures, they decided to drop the parity bit from public keys entirely, a choice widely believed to have been made just to break compatibility with BCH’s earlier Schnorr implementation. The result? Ongoing headaches for BTC protocol developers working with key tweaking and aggregation.
So we’re not the first ones to drop parity. We just did it without breaking anything.
Note: We’re in the process of moving everything over to the new name. The old website already redirects to the new one, but you may still spot the old name in some places as we work through the transition.
