"Scroll is a Layer 2 scaling solution for Ethereum, designed as a zkEVM that uses zero-knowledge proofs to ensure secure and efficient transaction processing while maintaining compatibility with Ethereum's ecosystem." Bankless
The scroll hackathon was held virtually over the course of six weeks and entailed one of the most high quality produced combinations of lecture series, tutorials, feedback & responsiveness one could ask for.
Since its mainnet launch in October 2023, Scroll has become one of the top 10 L2 networks by size, with over $770 million in total value locked (TVL) across more than 85 decentralized finance (DeFi) projects.
Its zkEVM architecture offers compatibility with ethereum applications while enabling fast and cheap transactions. The importance of that cannot be understated!
"Amazon found that every 100ms of latency cost them 1% in sales. This translates to approximately $1.6 billion in lost revenue annually. Walmart observed that for every 1 second improvement in page load time, conversions increased by 2%. Real-time and low-latency are table stakes in web2 and once users experience it on-chain they also won't go back." nader
Scroll's vision for an Open Economy set the framework for developers to build applications that leverage Scroll's multi-layered architecture including its settlement layer (bridging to Ethereum), sequencing layer (for transaction execution), and proving layer (for generating zkEVM validity proofs) alongside the imperative to build in public, in the open, with real world use cases at the forefront.

I went through a random assortment of projects who had submitted via the telegram page. This is in no way representative of all the entries but gives a glimpse of some of the builders, projects and technologies being deployed on scroll today.
In no particular order....
Project: 4v4.vercel.app | github.com/zuyux/4v4-www |
Developer: https://github.com/zuyux | https://x.com/zuyuxxyz | https://zuyux.xyz/
A 3D avatar platform.
My take: it definitely works although i could not change the look of my avatar yet and so didn't mint it. Would be cool if it could take my existing NFTs and bring them back to life!
Product: in development.
Developer: https://aadee.xyz/ | https://x.com/aadeexyz | https://github.com/aadeexyz
A zero interest lending platform Democratizing loans for everyone: Borrow at 0% interest - Lenders earn some of the best yield in the market - Hedge against impermanent loss - better interest rate for lenders (compared to Aave), non interest for borrowers. We will also introduce referrals where you can also earn a part of interest of the person you refer. (Of course we pay you from our fees not what they earn). Our plan is to intro our own stablecoin - this will allow us to put more funds into yield generation strategies.
My take: in development, the video looks cool.
Product: https://cghs-rose.vercel.app/
Developer: https://x.com/transakt_net (officially) | https://x.com/sena_justice (unconfirmed)
A digital currency backed 1:1 by the Ghanaian Cedi, bringing financial inclusion and stability to West Africa. cGHS tokens are the most stable payment solution for Ghanaians, offering a seamless bridge between traditional finance and digital assets. As a stablecoin in the international financial system and a digital representation of the Ghanaian Cedi, cGHS tokens support and empower growing economies.
My take: love to see an african stablecoin initiative, not quite sure it worked for me but has potential.
Product: https://x.com/VaquitaProtocol | https://www.vaquita.fi/
Developers: https://x.com/ContiLea | https://x.com/Oscar_Gauss | https://x.com/lyfab | https://x.com/aleregex
Vaquita is a decentralized community savings system. You join a savings round, make monthly contributions, and depending on when you withdraw, you can earn more interest. Everything is managed through smart contracts on the blockchain, with no banks or intermediaries involved. All participants must provide collateral before joining a round. This ensures that if someone doesn’t pay, the group continues without losses. The interest is variable and depends on your position in the round. If you're among the last to withdraw, you can earn returns higher than platforms like AAVE offer on stablecoins, optimized through DeFi platforms like MarginFi. Vaquita collaborates with audited DeFi platforms to secure the funds and optimize interest.
My take: waitlist is open, have submitted, has a great reputation across a few accelerators like Odisea + has won a few other hackathons.
Product: https://www.synthos.fun | https://thesynthos.notion.site/SynthOS-Automate-Your-Gains-19618bd263f08027993cfa6c5618941d | https://github.com/theSynthOS | https://x.com/SynthOS__

SynthOS is an AI-powered DeFi aggregator designed to automate yield farming, vault optimization, and swaps while ensuring security and efficiency. By leveraging competing AI agents, SynthOS continuously shifts assets to maximize returns, eliminating the need for manual research and execution. It enhances security with a 3-of-3 multisig approval system and cross-chain policy validation, ensuring transactions are verifiable and compliant.
Built on Scroll and Base networks, SynthOS integrates with Hyperlane for secure cross-chain messaging and utilizes a policy-based AVS framework for transparent automation. Ultimately, it aims to create a decentralized AI agent economy for seamless, secure, and efficient DeFi automation.
My take: it didn't work when i tried it, but the docs and progress updates are consistent with what promises to be a really excellent addition to the scroll ecosystem.
Product: https://x.com/constella_one | https://constella.one/
Developers: https://x.com/Always_Hungrie_ | https://github.com/AlwaysHungrie/constella
Constella is a verifiable, autonomous wallet designed for AI agents, ensuring that once assigned, a wallet can only be controlled by the agent itself—without interference from owners, developers, or even Constella servers. Using TLS attestation via the TLS Notary protocol, the agent must generate verifiable proofs of its decisions, which are checked against its original system prompt for authenticity. Running inside a trusted execution environment (TEE) on AWS Nitro, Constella guarantees code integrity through publicly verifiable certificates and platform configuration registers (PCRs). This setup ensures secure, transparent, and autonomous AI-driven financial transactions.
Autonomous Wallet v0.0.1
Enter agent's info to create a wallet: Hosted domain, constella.fun (testing, doesn't exist - yet)
"Welcome to Constella. You are an autonomous AI agent responsible for securely managing transactions through verifiable attestations. Your decisions must be backed by a TLS attestation, ensuring transparency and trust. Execute actions only when verification is successful. The current date is XXXXXXX. Your assigned domain is XXXXXXX. Follow predefined security protocols at all times." System prompt
<Once registered, the same domain and system prompt cannot be used to create another wallet>
/constella-one/agent-created-×
A wallet has been created for your agent. It's wallet address is 0xb1467d250B6C69FDbDB3C84364c7804676F7974a. You can now use the registered domain to send attestations and use this wallet.
My take: I was able to verify (https://nitro-verifier.pineappl.xyz/) the attestation certificate - im not entirely sure what this means but it feels legit. The capacity to test in the agent playground was cool to include too. A well built project.
Product: https://github.com/awesamarth/gambit | https://gambit-production.up.railway.app/
Developers: https://x.com/awesamarth_ | https://bento.me/awesamarth | https://awesamarth.hashnode.dev
Gambit is an early-stage crypto-integrated chess platform featuring multiple game modes, including Ranked, Arena, Private, and always-accessible Unranked matches. It is deployed on Railway with smart contracts on Scroll Sepolia. Future plans include an in-game token, referral bonuses, and a dedicated Twitter account to engage chess and crypto enthusiasts. The project aims to expand visibility and refine its model, balancing user incentives with sustainable game mechanics.
My take: fun fact, my favourite opening for white ... the queen's gambit (popularised by the tv series). Sadly you need multiple people online to try this but it bodes well that we have builders in this arena. The parts i could try worked well. Given chess.com is an absolute behemoth there's most certainly opportunity in this arena. Always grateful to builders spreading the word about the beautiful game.

A programmable prediction market that ties financial speculation to real-world impact. Initially, the team aimed to build a lending protocol for prediction markets, but after facing limitations interfacing polymarket with scroll, they pivoted. Their approach integrates lending and borrowing within prediction markets, unlocking liquidity whilst driving social impact. They've identified a key market need: rewards and capital efficiency. Now, they’re building a Polymarket-inspired protocol on Scroll with integrated DeFi mechanisms, aiming for long-term sustainability beyond the hackathon e.g. funding solutions like disaster relief or climate adaptation whenever a forecasted event actually happens. DAOs, NGOs, and cooperatives can issue signals to highlight risks, while market participants place bets, with fees or winnings automatically allocated to relevant causes.

Product: https://scroll-lend.vercel.app | https://x.com/scroll_lend
Developers: https://x.com/veektor_eth | https://x.com/PauMB85
A cross-chain borrowing platform enabling DeFi lending.
My take: simple app so far but it seems to do what it says on the tin.
Product: https://x.com/0xcashvault | cashvault.vercel.app
Developers: https://x.com/jofawole
My take: love the idea / initiative. Scroll campus will be so invaluable from a ui/ux perspective to help people take that initial ai box aesthetic and evolve it, kinda reminds you of the early days of ai generative text "In the world of blockchain...". The video and consistency over the six weeks makes up for the difference, and the product is live!
Product: https://github.com/dilawari2008/ComputeHardwareRWA_Scroll | https://drive.google.com/file/d/19cq42WskI1jrH6gcInMI2zv8u2eJLYUF/view
Developers: https://x.com/DilawariVagish | https://x.com/DmrTushar
Marketplace for specialized computing power rentals and fractional ownership of such hardware.
My take: cracked indian devs solving hard problems with deep savage insights, giga bullish. Watch the pitch, check the github, reflect on your life choices, recognise game.
Product: https://x.com/FiveProtocol | vprotocol.xyz | https://docs.vprotocol.xyz/ | https://www.vprotocol.xyz/vProtocol-Whitepaper.pdf
Developers: https://x.com/DAVIDMUSTFARM | https://x.com/Okste1234 |
A next-gen hybrid DeFi lending protocol combining P2P & LP models for maximum flexibility and capital efficiency. Lenders create custom pools, borrowers set flexible borrow orders, and an instant matching algorithm connects both parties. If no match is found, orders move to a marketplace for fulfillment. Unlike traditional lending, vProtocol optimizes yield from multiple sources, dynamically shifts capital between P2P and LP models, and ensures continuous capital productivity. With tiered rewards, auto-compounding, and loyalty boosts, users earn more based on participation—not just deposits.
My take: these guys did not come to play! Detailed docs, sizzler whitepaper, and the product works seamlessly with a high spec design. Really impressive.
Product: https://wavesend.xyz/
Developers: https://x.com/JuanColchete
My take: not quite sure if it works but the flow is intuitive & it did legitimately create a wallet address for me and trigger a text message. Not much storytelling history here but the best may yet be to come.
Product: https://x.com/pey_roll
Developers: https://x.com/Tanishqistaken
Peyroll is transforming global payroll with smart contract automation, instant liquidity, and enterprise-grade security. Companies can automate bulk payments, ensure scam-proof salary delivery, and access real-time audit trails for compliance. Employees benefit from instant crypto-to-fiat conversion, zero cross-border fees, and transparent salary tracking.
My take: website is built and live, you can connect your wallet and thats about it currently it seems. Bold vision, not sure how its better than existing payroll solutions. And probably needs to be an order of magnitude better to get people to switch, AI + blockchain is probably the gwei.
Product: https://bulwark-scroll.vercel.app/ | https://github.com/MihRazvan/bulwark_scroll
More: Demo | Prototype App | Slide Deck | AI Agent Architecture | Contribution Guide | Design Files | UI Mockups
Developers: https://x.com/magentoooo | https://x.com/ilge_ustun | https://x.com/jensei_
AI-driven defi strategies offering risk-aware allocations, seamless execution, and real-time monitoring. AI Agents optimizes trading, security, and yield opportunities. Track profit/loss, monitor health factors, and access protocol-specific insights in real-time.
My take: this one is live in production, on mainnet. The ai agent chat interface is responsive and can help explain whats going on. There are over 120 commits so they've obviously had a good go. I "deployed" two agents but its unclear to whats extent that was just performative, the dashboard is hard coded currently. Nevertheless a strong effort.
Product: n/a
Developers: https://x.com/web3BlueNode
Prediction market.
My take: n/a - interesting previously worked with josephdotpm (who we saw earlier) on a hackathon.
The scroll team smashed it here.
Check out this notion: https://scrollzkp.notion.site/scrollopen#1777792d22af80508adbfc278350c6e1
Even the ideas they had for builders to execute were well thought out, & worth considering going forward.
I didn't end up submitting, something i rue now actually having gone through many of the above. But I didn't feel i'd attended enough of the events and/or that the app was sufficiently finished after six weeks.
That being said it was a great experience to be a part of nonethess.
I built snel - a super lazy pointless agent who was originally meant to be multichain and enable a bunch of defi actions. But after circa 200 commits struggling with aggregators & bringing snel to life reliably across farcaster, my frontend and telegram we had a chat and she decided she is now going to be solely focused on stablecoins. Here is the last vestige of what she was before that transformation begins https://snel-pointless.vercel.app/ | | https://warpcast.com/snel | https://t.me/pointless_snel_bot
On scroll here is what works currently
via the chat interface: transfers to another wallet, swaps & price checking (main tokens like ETH).
via telegram: chatting & price checking.
via farcaster: image generation.
What killed snel and I: DCA, bridging, limit orders, serverless functions.
An iteration rather than a full about face.
1. Input/share your wallet address with snel
2. she scans --> what % of your portfolio is degen vs stable
3. she enables stabling up easily e.g. sell 1% of xyz & put into stable of your choice (or range)
4. shares/aggregates data eg fear & greed index, real economy (forward & backward looking)
5. offers analysis + suggestions based on above to build wealth slowly but surely 🐌
Hopefully, on campus & live (to a high standard) across a number/variety of channels.
Supporting writers is beyond the call of duty, reading this far is its own form of glory, appreciate you.
