Zephyr

Buy crypto, decentralized, in 1 minute... ☑️ Testnet ☑️ Audit 👀Open sourcing ~ 1 week 👀 Setup ceremony ~ 1 week ⏳Mainnet ~ 3 weeks

5/ We are also open sourcing our smart contracts. These contracts, as well as our Venmo circuits and overall architecture, were audited by Trail of Bits. github.com/Notebook-Labs/…

4/ We also built a backend for verifying emails and DKIM signatures on top of SSH, SHA and array parsing circuits built by circomlib, @0xPARC , Double Blind (doublebind.xyz) and @theyisun. This backend can be found here: github.com/Notebook-Labs/…

1/ Today we're excited to open source some of our core infrastructure in an attempt to further advance adoption and development of ZK Apps! 👇🧵

Excited to announce that we'll be starting our trusted setup ceremony on Monday for our Venmo and CashApp circuits! This marks a key milestone for Zephyr and is the last key step before our mainnet launch. Reach out to us if you're interested in contributing!

An underappreciated aspect of permissionless stablecoin onramps is their power to serve as economic equalizers. For citizens in inflation-prone countries like Argentina, this tech democratizes access to dollars, eliminating the premium on physical currency.

Google Pay circuits written ✅ Setup ceremony for Venmo, Google Pay and Cash App coming soon... 👀

Just finished our Cash App circuits 💵 Excited to launch them soon

Our SDK is coming soon... Which projects should we integrate with?

Did anybody say there's a second wave of testnet invites coming?

Excited to announce our integrations with ████ and ██████! What payment methods do you want to be able to use with Zephyr?👇

When building Zephyr, we chose to prioritise a fast UX for on-rampers so went with a model where off-rampers act like LPs and escrow their funds and on-rampers submit proofs to unlock them. The orderbook ensures that 2 on-rampers don't attempt to unlock the same funds with only one of them receiving their crypto. It would be interesting to flip this model. Venmo has a request feature so you could verify in a ZKP the email saying that a buyer sent a request. The LP would then have a dispute period where they can submit a ZKP showing that the buyer either canceled the request or the LP did in fact fulfil it in time. Each p2p payment method has a lot of quirks that can lead to interesting mechanism design.

@ZephyrExchange @gakonst Did you look at any AMM models where LPs state how much off-chain liquidity they can provide, and you use incentives / collateral to ensure they fulfill swaps? Or is there a reason it has to be an orderbook? Maybe pricing gets too complex, since LPs must consider offchain fees?

could you use zkemail to pull assets from a smart contract based on a venmo email receipt verified on-chain and host a near-trustless fiat onboarding p2p marketplace?

Excited to kick off our audit with @trailofbits today! Once completed, we'll open-source both our code and documentation. Looking forward to community collaboration and insights!

@EdsonGarderner Of course. Just emailed a Loom video and it's also public on the Telegram chat.

@ZephyrExchange I want to see instructions for retirees: link -action - screenshot 😅

Just sent out the first wave of testnet invites! 🌊

@EdsonGarderner Hey, thanks for your feedback - we will send out a video shortly! Which actions weren't clear?

@ZephyrExchange Can we expect a short video instruction from the team? Certain actions are not completely clear, it would be great to see everything in a short video format for more progress in the test
