Hi everyone! Due to technical reasons, I had to change my DRep ID. Here is the new one: drep1ygqcj6cjm8arjwcxax7kcwem93k6jszc3lvufmxszv0ep9cp5kely Apologies for the inconvenience 🙏 Some details below 👇 Unfortunately, the original DRep ID was created with the Cardano CLI and was not properly supported on the governance portal. In particular, it was displayed as "inactive" and "unverified" on the portal, which obviously detracts people from delegating. Moreover, I could not use the portal to vote. I had to create transactions manually using the CLI, which is rather time-consuming.

We surveyed the ecosystem but found that most libraries still required a lot of low-level tinkering. We built `zkfold-bitcoin-lib` to provide the high-level, composable abstractions we actually wanted to use. Excited to see if finally being shared with the community!

We're open-sourcing zkfold-bitcoin-lib — a Haskell library for easy Bitcoin transaction building. Easily build transactions — Use an intuitive API to construct clear, composable abstractions. Utilize modular data providers — Query ledger state information from a Bitcoin node or mempool.space, same API irrespective of the provider you use. You can also build and contribute your own data provider! Easy testing — Simple regtest harness to test your transactions against a private testnet to exercise full flow. In addition, we're also making public the on-chain code for our atomic swap implementation on both Bitcoin and Cardano. MIT licensed. 🔗 github.com/zkFold/zkfold-… 🔗 github.com/zkFold/atomic-…

Our new documentation portal simplifies the Smart Wallet integration. If you need further assistance with it, just send a message to @zkFold.
zkFold@zkFold

Smart Wallet developer update 🔥 New documentation is now live at docs.zkfold.io We have consolidated our backend APIs and created a comprehensive guide on how to integrate Google account-based wallets into your application. Just a reminder: - zkFold Smart Wallet tech allows your app to send crypto to any Google account - You can create both custodial and non-custodial wallets/apps/platforms using our APIs - Our frontend is open-sourced and can be used as an example of such integration Our team continues working on the next version of the API and the frontend. Massive UX improvements on both sides. Stay tuned!

The fact that they could not keep this obviusly top secret info "in secret" is probably a good thing. Gives me hope that information of great public importance cannot be silenced easily. Prediction markets are truth-seeking machines after all!

Cardano Adoption Starts with Simplicity That’s why we built zkFold Smart Wallet, designed to make crypto feel as natural as the apps people already use. How it works: 1. Log in with your Google or Apple account and your wallet is created instantly. 2. Send ADA by Gmail - the recipient doesn’t need to set up a wallet first. 3. You are protected by Zero-Knowledge security. For users it’s effortless. For builders it’s a simple API that adds one-click login and ZK security to any Cardano project. Billions of Web2 users are already familiar with Google. Now they can discover Cardano without even realizing they’ve stepped into Web3. Simple. Private. Scalable. That’s how @zkFold accelerates Cardano adoption.

@zkFold is bringing Web2 users to Cardano Most people never join crypto because the first step feels too hard: seed phrases, long setups, confusing UIs. zkFold changes that. Now anyone can create a Cardano wallet in seconds by simply logging in with Google or Apple. ✅ No seed phrase ✅ No downloads ✅ No technical learning curve And when they’re ready to send ADA - they just type a Gmail address. The recipient doesn’t even need a wallet yet. When they log in, the funds are there. It’s the simplest way to onboard new users to Cardano, turning familiar Web2 habits into real blockchain adoption. This is how we make Cardano usable, not just powerful.

It was great to return to Berlin for this year's Cardano Summit. Very productive for @zkFold!
zkFold@zkFold

@zkfold is back from @CardanoSummit and we are still impressed by how builders reacted to our smart wallet. The thing that clicked for everyone: 👉 𝗬𝗼𝘂 𝗰𝗮𝗻 𝗻𝗼𝘄 𝘀𝗲𝗻𝗱 𝗔𝗗𝗔 𝘁𝗼 𝗮 𝗚𝗺𝗮𝗶𝗹 𝗮𝗱𝗱𝗿𝗲𝘀𝘀 No separate wallet setup. No seed phrase. No “what’s your address?”. If someone has Gmail, you can send them ADA. For you as a Cardano builder, this means: - Onboard non-crypto users in seconds - Turn every Gmail user into a potential Cardano user - With a simple backend integration, grow your user base massively If you’re building on Cardano and want to plug this into your product, DM me or drop “WALLET” in the comments. Happy to walk you through it.

We disrupted a highly sophisticated AI-led espionage campaign. The attack targeted large tech companies, financial institutions, chemical manufacturing companies, and government agencies. We assess with high confidence that the threat actor was a Chinese state-sponsored group.

From our recent private conversations around @zkFold Smart Wallet, I realized that the idea that you could send crypto assets to ANY Gmail address blows people's minds :) Yes, you can totally do it with our tech. When you do so, the assets are locked in a Cardano smart contract. To unlock them, the user presents a zero-knowledge proof of Google account login. This is GREATLY different from virtually any other "Web2-login" solution for cryptocurrency wallets. All they do is create a multi-sig where parts of the key are stored with 3rd parties. And it's those 3rd parties who require your Google login proof to exchange for a key shard or signature. Those other solutions can only send to existing wallets and, therefore, cannot be used to acquire NEW users, unlike Smart Wallet tech. Having a Web2 login option reduces some of the friction anyway, that's true. However, when you send crypto with Smart Wallet, the recipient gets an email with a link to install YOUR wallet or dapp. The money is already there; you just need to log in. Isn't it powerful? 😎
