After 1,306+ days of continuous uptime of our ADA/USD price feed across 3 iterations, we've decided to pause our services while we navigating our next chapter.

Thank you to @Cardano_CF @emurgo_io @IOGroup @Catalyst_onX and @IOHK_Charles for giving us the opportunity to build for 5 years on this amazing chain. Thank you to all our community members, ecosystem partners, customers, holders, and supporters.

Charli3’s downtime and network disruptions are measured in seconds. From Oct 2022 to May 2026, feeds stayed up an unprecedented 99.9999%+ of the time.

A lot of has to do with being Cardano native, but also our inhouse alert and monitoring systems combined with a great team with enterprise grade SOPs.

Pyth can better speak for their own architecture…

Simply put:
Charli3 is a native oracle to the chain. Pyth is not.

We have several solutions, now paused.

1. Both our push and pull oracles have 5 external node validators posting results directly on chain.

2. Our oracle partnerchain retained the security guarantees of Cardano while external validators posted data on the sidechain.

In tests we ran 25+ validators, though the reward economics favours 5-15 sized node networks. So we had validators updating 50+ token price pairs every 6s, pushing them onchain in a single bundled transaction. This was designed by our team in collaboration with @txpipe_tools .

We built integrations with several major chains enabling hundreds of thousands of price pair data.

Teams like @fluxpointstudio @SyncAI_Network @lambdac_labs @AscendPerps shipped real working (and winning) solutions in four days using our pull oracle infrastructure.

@USDMOfficial ran our proof of reserve solution for 18+ months. It was bulletproof.

A native Cardano oracle unlocks innovation and onchain activity.

It is the infrastructure that is necessary for builders to focus on what they know best.

Not worrying about data integration.

We’ve been in the background, always, supporting our builders.

This project, developed in partnership with Charli3, was made possible by a Cardano Project Catalyst F12 grant which received ₳ 67.9 MILLION YES votes, or roughly $26,874,820 (at the time) in $ADA voted for this project to be funded. Our platform revolutionizes e-commerce by transforming discount coupons into verifiable NFTs on the Cardano mainnet. Aimed at enhancing trust and convenience, it allows shoppers to access reliable, blockchain-verified deals from top merchants while offering a global platform for promotion.

Our project features seamless integration with Adobe Commerce and Magento 2 Open Source e-commerce platforms, empowering merchants to manage and mint verified coupons directly from their administration control panels. Merchants can submit promotions with a single click, automatically minting them as NFTs on Cardano using Adobe Commerce and Magento 2 Open Source extensions developed by Veralidity. In order to ensure coupon code data is always accurate, Charli3 verify's the merchants coupon data, ensuring it's acurate and aligns with the merchant's active promotions. The system also handles real-time updates—if a merchant modifies a promotion, or if the promotion is triggered to be inactive due to various factors such as expiration date or coupon usage as an example, the NFT is automatically updated on-chain, maintaining accurate and active coupon codes effortlessly.

This was our q4 2025 strategy.

Thank you @DeOpenSourceGuy

[Christian Taylor @DeOpenSourceGuy]

I worked with the Charli3 team starting around October of last year, following the launch of the Paid Open Source Model and initial program setup at Intersect.

Charli3 had been a closed-source project, primarily funded through Catalyst. The opportunity was straightforward: support a Catalyst-funded team in transitioning their work into a sustainable open source community asset, while providing a viable path forward for the maintainers.

This aligned directly with the goals of the Paid Open Source Model. Several established programs were positioned to support the transition:

1) Incubation Program – Charli3’s native oracle had already received committee-level approval to be incubated under Intersect as a neutral open source host.

2) The Maintainer Retainer Program – designed to provide part-time support for contributors, offering a 12-month runway for ongoing maintenance and improvements.

3) The Tooling Sustainability budget – intended to cover short-term operational needs during the maturation phase and only to apply post incubation.

From the committee perspective, the direction was clear. Both the Open Source Committee and Technical Steering Committee had reviewed and accepted the incubation proposal. Funding was discussed and earmarked.

The strategic value was evident: helping an existing Cardano infrastructure project successfully transition to open source and strengthen it as an ecosystem public good.

After I left Intersect, I no longer had direct visibility into the project’s status. Despite the prior approvals, applications, and clear alignment with program objectives, I did not see visible further progress on the initiative.

This experience highlighted a key challenge in open source sustainability. Projects moving from closed to open source typically need more than initial approval and earmarked funds. They benefit from reliable neutral hosting, maintainership support, operational resources, governance clarity, and consistent institutional follow-through.

Situations like this are exactly why I’ve advocated for the dOSPO concept: a dedicated, accountable, externally governed mechanism that can help ensure continuity for critical open source infrastructure—so important projects don’t lose momentum due to transitions, bottlenecks, or changes in organizational priorities.

The goal is not additional bureaucracy. It is continuity and reliable https://t.co/cJA8N8HMmq source sustainability is not only about funding. It is about building dependable systems that can guide projects through transitions and help them remain viable once the community depends on them.

For full transparency, experiences like this were one of the factors that contributed to my resignation. I chose to step away so I could continue focusing on practical ways to strengthen open source support structures with consistent execution at their core.

We were recently migrated our moneta feed to ADA rewards, transitioning the c3 reward token to a governance token.

This would mean node operators got rewarded in ada or usdm or any token they want (eg a DeFi protocol using the pull oracle could build into a user flow direct payment to networks with their own token).

But we never got the stage of implementing this change.

[Charli3 Oracles 📍Reliable, Secure, Trusted @Oraclecharli3]

@BitBlocks368 @fluxpointstudio The team is engaged in strategic partnership and stewardship discussions.

Our infrastructure is decentralized. Charli3 is not necessarily needed. Transitioning governance to Intersect was our original thesis in q4 2025.

Thank you again to all our hackathon participants!

Although bittersweet given our recent pause of services, this event is one of the most cherished by our team.

It represents the potential of native oracle adoption on Cardano. And the potential of what the amazing engineering team at Charli3 produced.

🙏🫡💪 keep building. And good luck pitching @DraperDragon !

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.

Thank for delivering high quality tooling to support our open source infrastructure!

[SyncAI Network @SyncAI_Network]

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.
