🚀 Introducing Smart Wallet 🚀 Smart Wallet is an all-in-one API library for implementing a Cardano wallet. The library is backed by an on-chain smart contract and a set of backend services. Today, Smart Wallet, with its first feature, Web2 login, has officially hit the testnet!

Met a few true Cardano gurus at the CV Summit in Switzerland 🇨🇭 Cardano isn’t just tech, it’s people! @Padierfind @MasumiNetwork @sheldon @_MrHunt_ @SundialProtocol

Yuti v1.5 coming to testnet next week. @zkFold smart wallet integration with Google!

✅ zkFold — General-Purpose ZK Rollup @zkFold is building zero-knowledge tooling and rollup infrastructure tailored for Cardano. The aim: scale where it counts, protect privacy where it matters, and align with Plutus dev flows.

Crossed paths with two founders I’ve known since our early days in the space. @zkFold @Stasmarr @SociousDAO @txpipe_tools

The vision behind @zkFold is strong...and @Stasmarr the Co-Founder of zkFold is live now with technical insights on zkRollups on @Cardano at the Dev/Gov Day Event in Las Vegas.

Here we go!

What does zero-knowledge mean? Zero-knowledge means “I can prove I did something correctly, without telling you the details.” It’s like proving you solved a puzzle without showing the puzzle itself. On a blockchain, this keeps things private and efficient. Verifiers check the

Just landed in Las Vegas for #RareEvo2025 (@RareEvo). I’ll be speaking about the ZK Rollup by @zkFold. If you’re around and working on L2s or infrastructure, let’s find time to talk.

What is a zkRollup? Imagine everyone at a concert buying tickets. Instead of showing each purchase one-by-one, someone summarizes all sales on a sheet. That sheet includes proof that all sales followed the rules. That’s what a zkRollup does: bundles lots of transactions and gives

Thank You, Cardano Community! 🙏 We’re deeply grateful to everyone who reviewed, questioned, and voted for our proposal. We have reached the 67% threshold! Your support is what makes a progress possible. Thanks to your trust, we’re excited to continue building one of the most

Layer 1 security, not shortcuts The rollup doesn’t invent its own rules, it inherits Cardano’s. If the zk proof fails, the L1 rejects it. That means dApps stay secure without running on the main chain. Finality, determinism, and settlement all still come from L1. Vote now

Cardano’s design is perfect for zkRollups. By combining deterministic EUTXO with zk proofs, we enable parallel execution at scale. Vote now ➡️ https://t.co/NxovLgQe5f

zkRollups bring privacy, cost-efficiency, and scalability to Cardano. dApps benefit by offloading heavy computations to L2, while users enjoy faster confirmation times and cheaper fees. It's not an option - it's critical infrastructure.

Our zkRollup is more than a scalability upgrade for Cardano - it's a structural shift. By batching off-chain transactions and verifying them with a single proof on L1, we will have cost efficiency and performance while maintaining decentralization. dApps like DeFi protocols and

If you buy a ticket, it’s recognized almost instantly; when you trade an in-game asset, the update is final faster than a typical L1 block cycle. Fraud? Hard - because the proof would fail if any rule were broken. The platform maintains speed; users retain chain-level trust. This

The zkRollup executes these mini-transactions off-chain, compiles the new state (who owns what, which tickets were validated), and proves correctness to Cardano with one compact proof.

Gaming, Tickets, and High-Frequency Actions A game or event platform might generate thousands of tiny actions: item trades, score updates, ticket scans, loyalty point credits. Forcing each of those onto the main chain in real time is like routing every text message through a

Sending Money Abroad, Cheaper and Faster Today, a cross-border micro-payment can feel like mailing cash with three middlemen: slow, fee-heavy, and opaque. On the zkRollup, dozens or hundreds of such transfers are bundled together. The rollup prepares a proof that every sender had

Scalability that holds up You can’t scale by brute force on L1. zkRollups offload execution, then post a single proof to Cardano. It’s like compressing 10,000 transactions into one. The result? High throughput, low congestion, and no hit to decentralization. Vote now

Why it's awesome? Public blockchains are like glass houses - everything visible. zkRollup adds curtains, making crypto safer for everyday use, like health records or voting. It doesn't sacrifice speed; it enhances it. For five-year-olds, it's magic invisibility cloaks for your
