Cardano developers unveil ODATANO, targeting SAP—the world’s largest enterprise software ecosystem.

The Cardano Developer Portal has published an interview with Maximilian, founder of ODATANO. ODATANO is a Cardano integration tool for SAP enterprise environments, which encapsulates the Cardano blockchain into a standard OData V4 API, allowing enterprise developers familiar with the SAP development ecosystem to integrate with Cardano without deep expertise in underlying blockchain technologies. Maximilian stated that traditional SAP developers aiming to connect business processes to Cardano usually need to master technologies including the UTxO model, transaction construction, CBOR serialization, fee calculation, collateral, and key management. ODATANO encapsulates these complex blockchain operations in a service layer, enabling Cardano to connect to SAP applications as a standard OData service. Currently, ODATANO offers 31 entities and functions such as data reading, transaction construction, and signing, supporting queries of blocks, addresses, UTxOs, assets, and protocol parameters, as well as transaction construction, signing, and submission. The project can run as an SAP CAP plugin or be deployed independently. Maximilian also introduced reference applications built on ODATANO, including TRACE, QUANTIX, FINCA, and x402. Among them, QUANTIX is an oracle-based B2B raw material procurement and settlement application that won the 2026 Charli3 Oracle Hackathon. According to the Cardano Developer Portal, ODATANO received funding through Cardano Catalyst Fund 14. The project is currently developed solely by Maximilian, with 1,285 automated tests completed and a code statement coverage rate of 99%.

Cardano wallet service provider SecondFi updates its wallet migration tool.

According to official announcements, Cardano wallet service provider SecondFi has rolled out a new wallet migration tool. The tool supports wallets that have delegated ADA to staking pools but lack sufficient balance to cover network fees for migration, with SecondFi covering the associated on-chain fees on their behalf. Staked ADA balances are now included in the app’s asset overview. If your balance previously showed zero in the app, you should now see your staked balance after this update. Users holding delegated ADA still need to complete the migration, but no additional wallet top-up is required. The migration is only accessible within the official SecondFi app or browser extension that has been updated to the latest version; there is no separate migration website or new application.

Cardano Foundation CTO to Step Down on August 31

Under the current roadmap, the Foundation’s board of directors and executive team will continue to work closely with the head of technology and senior business development, staying focused on enterprise adoption.

Wanchain-Cardano cross-chain bridge exploited, approximately 515 million NIGHT tokens stolen.

According to monitoring by BlockSec Phalcon, Wanchain’s Cardano cross-chain bridge was exploited, with approximately 515 million NIGHT tokens stolen from the bridge’s Treasury. BlockSec’s preliminary analysis attributes the root cause of the vulnerability to the non-injective encoding method used by the TreasuryCheck verifier for signed messages: 14 variable-length fields were directly concatenated to generate the message to be signed, without using separators or length prefixes. This allowed different field combinations to produce identical byte sequences, enabling attackers to reuse valid signatures to carry out the exploit.

Cardano will hand over control of its core software to an external team starting in August.

Cardano developer Input Output will transfer control of key blockchain components—including Haskell nodes, the Plutus platform, and the Daedalus wallet—to external professional teams starting in August, as part of its multi-year decentralization initiative. Independent firms such as Se7en Labs and Teragone will oversee portions of the core infrastructure. At least three Cardano implementations will be maintained in Haskell, Rust, and Go, under community oversight and formal specification management. Cardano is currently grappling with weak network activity and a sharp drop in the ADA token’s price. Founder Charles Hoskinson framed the restructuring and ecosystem-related setbacks as necessary "growing pains" on the path to full decentralization.

Cardano Founder Denies Resignation Rumors: "They are completely untrue and entirely fabricated."

Cardano founder Charles Hoskinson has denied rumors of his departure, calling them "fake, a complete lie, and totally fabricated." The rumors have spread widely—one London taxi driver even told visiting Cardano supporters that he had heard the founder was about to retire.

Cardano Founder Responds to Controversy Over $70 Million Bitcoin Transaction: Audit Fee Paid in 2016

June 15 — The crypto project Cardano is mired in controversy following a discovery by Thomas Braziel, an investor focused on bankruptcy claims and digital assets. Braziel found via company documents and on-chain records that roughly 1,090 Bitcoin from Cardano’s crowdfunding round has an unknown whereabouts. These Bitcoins were originally allocated to an Isle of Man entity—an early predecessor structure of the Cardano Foundation, which was dissolved in December 2025. In a post on X, Braziel questioned Cardano founder Charles Hoskinson, who was an early participant in that Isle of Man entity: What happened to this Bitcoin (now worth around $70 million) after the entity dissolved? Who controls the funds now? And is the situation transparent? Hoskinson responded during an AMA yesterday, stating the Bitcoin was used to cover audit fees for the 2016 crowdfunding sale, when the BTC was only valued at $454,000. Now, Braziel is requesting additional evidence from Hoskinson to validate this cl

Cardano Foundation's 1090 BTC Turns Into "Confused Account," Prominent Creditors' Rights Investor Calls for Public Disclosure of Fund Usage

June 8th. Thomas Braziel, a cryptocurrency bankruptcy creditor, posted on social media, stating that per Isle of Man company registration filings and Cardano’s official website, the predecessor to the Cardano Foundation – the Isle of Man Foundation – was set up during the 2015 ICO. Cardano founder Charles Hoskinson served as a supervisor for the foundation, which received roughly 1,090 Bitcoin (BTC). Now that the foundation was dissolved in December 2025, Braziel is calling for full public disclosure of the BTC’s whereabouts and the foundation’s governance documents. He clarifies he is not currently alleging any misconduct, only requesting greater transparency. As of press time, the Cardano team has not issued a response.

Cardano Founder Announces Intention to Take a "Brief Break" as ADA Dips Below $0.20 Amid Ecosystem Pressure

On June 4, Cardano founder Charles Hoskinson announced he’s taking a temporary break—this comes after he warned the blockchain ecosystem is bracing for a "wave of failures." Hoskinson’s comments sent Cardano’s native token, ADA, tumbling: it dropped below $0.20 for the first time in over five years, marking a nearly 70% plunge over the past year, and fell an additional roughly 10% right after his announcement. The news lands amid a string of recent setbacks for Cardano: TapTools, a four-year-old data analytics platform for the ecosystem, is shutting down. The turbulence follows an earlier community vote that rejected using treasury funds to support ecosystem development, leading to the cancellation of the planned 2026 Cardano Summit in Singapore. Earlier this year, Hoskinson had warned the ongoing bearish market would force some projects to close, predicting "a large number of failures" across Cardano’s network. He also voiced frustration over the community’s reluctance to allocate

Cardano 2026 Summit Canceled Due to Failed Treasury Proposal

May 31 — The Cardano Foundation announced that its scheduled 2026 summit has been officially canceled, as an on-chain governance vote failed to hit the required two-thirds support threshold. Earlier, the foundation submitted a revised proposal requesting 7.8 million ADA (approximately $2 million) in treasury funds to host the October summit in Singapore. Though the measure earned 65.21% support from DRep stakers and backing from a majority of delegates, it did not meet the 66.67% approval threshold required for treasury funding proposals. Cardano founder Charles Hoskinson and Cardano Foundation CEO Frederik Gregaard both publicly urged support for the proposal ahead of the voting deadline, but it ultimately failed to pass.

Cardano Founder: By 2035, AI Agent's Importance to the Internet Will Surpass Humanity, Google and Other Giants 'Very Panicked'

**Cardano Founder Charles Hoskinson: AI Agents Will Dominate Internet Activity by 2035, Upending Tech Giants’ Business Models** On May 7, Cardano co-founder Charles Hoskinson told attendees at Consensus 2026 that by 2035, most internet searches, transactions, and daily activities will be driven by AI agents—not human users—fundamentally upending the business models of tech giants like Google, Amazon, and Meta (formerly Facebook). Hoskinson noted AI agents won’t click on ads or exhibit brand loyalty, directly undermining platforms that rely on ad revenue. “Amazon, Google, Meta are in panic mode over the agent revolution—their entire business models are at risk of being overturned,” he said. He highlighted AI’s growing role in crypto: agents will increasingly handle tasks like due diligence, transaction execution, and DeFi interactions. Calling AI “one of the best things to ever happen to cryptocurrency,” he added it will drastically improve the industry’s currently complex user

Cardano Founder Wears McDonald's Uniform to Consensus Hong Kong Conference

On February 12th at the Consensus Hong Kong conference, Charles Hoskinson—founder of Cardano and co-founder of Ethereum—showed up in a McDonald’s uniform. He noted: “The crypto industry’s current state isn’t healthy. Things are getting serious: liquidity’s drying up, many people are feeling down, and Twitter’s flooded with unprecedented pessimism. It’s like a freshly cleaned garbage dump that’s now on fire.” But there’s a silver lining, he added. The key takeaway? Even if things look messy at the micro level, the macro picture is telling us we need a new paradigm, a new vision, a new narrative.

Cardano Founder: Has Lost Over $3 Billion in the Crypto Space, But Still Chooses to Continue Investing in Cryptocurrency

On February 6, CryptoBriefing reported that Cardano founder Charles Hoskinson disclosed in a live stream he still continues investing in cryptocurrency despite losing over $3 billion in the crypto space. Hoskinson stressed he is not motivated by personal gain, always rejecting controversial or high-risk opportunities and prioritizing ethics and principles over resources, connections, or influence. This has allowed him to steer clear of high-profile scandals like the FTX collapse and the Epstein documents. He has previously slammed some industry leaders for embracing the flawed "CLARITY Act" in pursuit of power, wealth, and elite standing. When discussing the current market environment, Hoskinson urged the crypto community to confront the downturn head-on, focusing on collaboration and ongoing development rather than short-term price fluctuations.

Cardano Founder Criticizes Trump's Crypto Policy Damaging Industry Outlook

On December 19, Decrypt reported that Cardano (ADA) founder Charles Hoskinson recently said in an interview that former President Donald Trump’s launch of a personal meme coin was “disappointing,” as it turned cryptocurrency into a partisan issue and undermined bipartisan momentum in Congress. Hoskinson also pushed back against Trump’s proposed national strategic crypto reserve plan— which includes Bitcoin, Ethereum and other digital assets— arguing the government should not intervene to pick market winners. He revealed that because he publicly criticized these policies, he was excluded from a private dinner with the former president and lost the chance to engage in the legislative process.

Cardano experienced a brief chain split on Friday due to an old code vulnerability, which went unnoticed possibly due to its "dormant" nature.

On November 23rd, as reported by Cointelegraph, due to a "format error" in a delegation transaction, the Cardano network experienced a temporary chain split on Friday. Delegation transactions refer to transactions where ADA is delegated to a staking pool. Although these transactions are valid at the protocol level, they can potentially lead to a code fault that affects network functionality. According to an incident report released by the Cardano ecosystem organization Intersect, this "format error" transaction exploited an old code vulnerability in the underlying software library of the Cardano blockchain, causing nodes to diverge in transaction processing and ultimately resulting in a network split. This vulnerability was caused by a staking pool operator named Homer J, who used AI-generated code to drive the transaction and has admitted responsibility for the network split. The staking pool operator was required to download the latest version of the node software to fix the issue a

Cardano Chain Fork Due to Stake Pool Operator Error Does Not Result in User Fund Loss

On November 22nd, as reported by Decrypt, the Cardano blockchain split into two chains on Friday. This was caused by a format error in a delegation transaction, which triggered a software bug. The transaction was validated on the new version nodes but rejected by the old version software, resulting in a network fork. The Cardano ecosystem governance organization Intersect stated in an incident report that this "toxic" transaction exploited a vulnerability in the underlying software library, splitting the network into a "poisoned" chain containing the transaction and a "healthy" chain without it. Charles Hoskinson, the co-founder, initially claimed that this was a "premeditated attack." However, later, a user named Homer J. publicly admitted responsibility, stating that their actions were negligent while trying to reproduce the "bad transaction" and relying on AI-generated instructions. The user stated that there was no malicious intent and no economic benefit was gained. Intersect co

By 2024, the foundation will hold 5.992 billion ADA and has received a total of 17.1 million ADA through staking, with a return rate of 2.7%.

Solana Co-Founder: Cardano's Proposal to Use Treasury Funds to Purchase Bitcoin is "Extremely Stupid"

On June 16th, Anatoly Yakovenko, a co-founder of Solana Labs, opposed the latest proposal put forward by the Cardano leadership to convert a portion of their treasury funds into Bitcoin. He stated that this idea is flawed, indicating poor treasury management and sending a wrong message to the Cardano community. He remarked: "Projects should hold 18-36 months' worth of operating funds in short-term U.S. Treasuries, and that's the extent." The controversy stems from a proposal made by Charles Hoskinson, the founder of Cardano, on June 13th, suggesting that the blockchain network could convert $100 million worth of ADA tokens from the treasury into Bitcoin and stablecoins. Hoskinson mentioned that the goal was to enhance Cardano's decentralized finance (DeFi) capabilities and address issues within its stablecoin ecosystem. However, critics believe that the proposal shows a lack of confidence in the ADA token. Crypto trader Aaron Dishner argued that this move could be perceived as Cardan

Cardano Founder Proposes Converting $100 Million Worth of ADA into BTC and Stablecoins

On June 13th, BlockBeats reported according to CoinDesk that Charles Hoskinson, the founder of Cardano, proposed in a live stream to allocate $100 million worth of ADA from the treasury and convert it into Bitcoin and stablecoins (USDM, USDA) in order to increase the proportion of stablecoins on-chain and boost the DeFi ecosystem. Charles Hoskinson stated that this action would not disrupt the ADA market and refuted concerns about liquidity. Currently, stablecoins on the Cardano chain only account for about 10% of the Total Value Locked (TVL), which is significantly lower than the scale of Solana's stablecoin ecosystem. This proposal seems to be inconsistent with the earlier emphasis by the Cardano Foundation CEO Frederik Gregaard that "TVL is not a key metric."

Cardano Founder: No Need to Strike Deal with Trump, Real Focus Is Legislation Bringing Cryptocurrency Regulatory Clarity

On April 18th, as per DLNews, Charles Hoskinson, the founder of Cardano (ADA), responded to not being invited to the White House crypto roundtable meeting by stating, "There is no need to make a deal with Trump." Hoskinson said that the current crypto policy reform being driven by the United States should focus on a "sustainable, long-term framework" rather than being tied to short-term political figures. During the White House cryptocurrency summit, Trump met with crypto executives such as Coinbase CEO Brian Armstrong, MicroStrategy Chairman Michael Saylor, and Ripple CEO Brad Garlinghouse to discuss digital asset regulation, but Charles Hoskinson, the founder of Cardano (ADA), was not invited. Hoskinson emphasized that even if Trump were to issue a crypto executive order, establish a Bitcoin Strategic Reserve, and appoint crypto-friendly individuals to lead the SEC during his tenure, what truly matters is the regulatory stability brought about by legislation.
