🔥 Ethereum just made wallets way safer! The Ethereum Foundation rolled out Clear Signing today. Instead of approving scary blind hex codes (the #1 reason users lose billions to scams), you now see plain English details of exactly what a transaction does — before you sign. No more “approve and pray.” This fixes the biggest source of user losses by letting you understand and catch bad transactions every time. Huge win for everyday users.

New to Cardano? Super useful upgrade to the @Cardano website for blockchain users, developers, entrepreneurs and beginners alike. This is the largest and most functional update by @Cardano_CF and community contributors to date! 🚀🚀🚀 Explore more here: cardano.org/apps/

Many oracle integrations are too complicated for normal devs so we shipped the first TypeScript SDK as our entry for the @Oraclecharli3 Oracles Hackathon (and we won!) 👏 TL:DR - any app, AI Agent or smart contract can now pull real-world prices onto Cardano with just a few lines of code! There is no Python backend, no complex oracle plumbing, no dealing with signatures, CBOR encoding, consensus logic or low-level Cardano infra. JUST: npm install charli3-js …and you can: → read live ADA/USD prices → refresh oracle data on-chain → use real market data inside AI agents, dApps, and smart contracts We even built: → a live Next.js oracle demo → an Aiken validator gated by real oracle data → an AI agent that settles USD invoices in ADA using the SDK as a tool AI agents, DeFi apps, prediction markets, RWAs, and autonomous finance all need reliable data feeds and making oracle infrastructure accessible to JavaScript + AI developers massively lowers the barrier to building on Cardano.

Congratulations to the Hackathon winners! Grand Prize Winner - 20,000 ADA "Quantix" by solo entry @maxalexweber QUANTIX is a B2B delivery settlement app for raw materials. Unlike regular RWA use cases, here it just tokenizes the needed facts about goods inventory, price, timestamp, signer set, and not the goods themselves. Conventional B2B delivery settlement runs on PDFs, EDI patchwork, and post-hoc reconciliation: ERP says one thing, the warehouse another, the price sheet is a day old, and disputes are settled by whoever has the better paperwork. QUANTIX replaces that with a single atomic Cardano transaction. Github Repo: github.com/maxalexweber1/… Demo Video: youtube.com/watch?v=g3_FEx… Best DeFi & Integrations - 5,000 ADA "Charli3 Perp" by team @AscendPerps - Charli3 Perp is a minimal implementation of perpetual trading using Charli3 oracle data. It connects verified on-chain ADA/USD price feed to pipeline executed with Midnight for orders, matching, and settlement. Best Real World Settlement - 5,000 ADA "AEGIS Parametric Insurance" by team @fluxpointstudio - Aegis is automated crypto insurance that pays out instantly when oracle-verified price conditions are met -- no claims process, no adjusters, no waiting. The oracle IS the claims adjuster. Best Oracle Tooling - 5,000 ADA "Charli3-js" by team @SyncAI_Network - Typescript charli3 SDK - Agent Integration pathway Community Choice Award - 5,000 ADA "Parametrix by team @lambdac_labs - Parametric risk settlement on Cardano (hedge against real world risks like rainfall or measurable events) Thank you very much to our sponsors for making this hackathon a reality: @Cardano_CF @Catalyst_onX @DraperDragon Big shout out to the @Oraclecharli3 team who volunteered their time to host the hackathon! And lastly, thank you for the incredible support from the community to make this event a success!

#13 SYNCAI — Team Syncai charli3-js is the first TypeScript SDK for the Charli3 oracle on Cardano. Until now the only official SDK was in Python, which is fine for backend scripts but useless if you're building a Next.js dapp, an AI agent (Masumi, Claude, OpenAI, etc), or anything that runs in a browser. Published to npm: npm install charli3-js. Full docs: charli3-js-bc690dc5.mintlify.app With charli3-js you can read the live price and, more importantly, pull a fresh one onto chain in a single call. submitRound2(lucid, "ADA/USD") collects signed quotes from the Charli3 feed nodes, runs IQR consensus, and posts a fresh aggregate tx to Cardano. That is the whole pull oracle flow in one line. The SDK handles the Lucid plumbing, CBOR encoding, Ed25519 sig checks, and slot-rounded datum internally so you do not have to think about any of it. npm install charli3-js, three method calls, and you have a working pull oracle integration within minutes. A very clean dev experience as any TypeScript library, running everywhere JS runs: React Server Components, Lucid in the browser, Node routes, LLM tool calls. Framework: - getPrice(pair) reads the classic push oracle feed. - getOdvReference(pair) reads the on-chain ODV pull-oracle aggregate, including freshness. - submitRound2(lucid, pair) pulls signed quotes from Charli3 feed nodes, runs IQR consensus, and posts a fresh aggregate tx to Cardano in one call. To prove it works end-to-end I wrote an Aiken price_gated_payout validator and a live Next.js demo on Vercel: connect Lace ‚Üí deposit 3 tADA ‚ refresh the ODV price on chain (Round-2) ‚ claim, all gated by a real oracle reading. I also shipped a GPT-4o-mini AI agent that settles USD invoices in ADA by calling the SDK as a tool, and a skill.md spec so any LLM can plug the oracle into its tool loop. 🎥 youtu.be/7n8Y-pAmlJg 🔗 Code: github.com/SkepX/charli3-… ❤️ LIKE to vote #C3Hackathon #Cardano
