On June 28, the European Council and Parliament achieved a political consensus on the Data Act, which moves the legislation regarding non-personal data closer to fruition.
Thierry Breton, European Union commissioner for the internal market, described the agreement in an X post as a “milestone in the reshaping the digital space.”
Another deal! ⁰Tonight’s agreement on the #DataAct is a milestone in reshaping the digital space.

The Data Act complements the Data Governance Act of November 2020 by clarifying who can create value from data and under which conditions. It stems from the European Strategy for Data, announced in February 2020, which also aims to position the EU as a regulatory frontrunner in the era of data-driven society.
The Data Act is part of the European Commission’s wider data strategy aimed at making Europe a global leader in the data-agile economy. In simple terms, the Data Act proposes new rules on who can access and use data generated in the EU across all economic sectors.
For the Data Act to become law, it must be approved by a vote of the European Parliament and the Council, which represent the bloc’s 27 member states. And once again, as with the Markets in Crypto-Assets (MiCA) regulation, the crypto sector is facing a major challenge. The problem raised by the new EU data law could permanently change the use of smart contracts in the European Economic Area (EEA) –– and not for the better.
Smart contract “kill switch”
The blockchain community is largely concerned about one provision in the Data Act, namely that automated data-sharing agreements contain a “kill switch” by which they could be terminated or halted in the event of a security breach.
Many blockchain experts contend that the current definition of smart contracts in the Data Act is broad, fearing it may lead to unintended consequences for existing smart contracts on public blockchains. For example, the text of the upcoming law doesn’t distinguish between just digital contracts and smart contracts utilizing distributed ledger technology.
But above all, the Data Act supposedly doesn’t give clear details about the conditions under which safe termination or interruption kill switch should occur, and it is hard to predict the potential outcomes with a higher degree of certainty. The smart contract architecture often doesn’t allow for termination or interruption, as blockchain technology is praised for being immutable and irreversible.
The Data Act also doesn’t say exactly what a “data sharing agreement” is, and it doesn’t explain if the smart contracts currently ubiquitous in Web3 applications follow these kinds of agreements.
“By design, most of smart contracts don’t offer a termination or interruption feature and are often un-upgradable to ensure higher levels of protection from abusive behaviors,” Marina Markežič, executive director and co-founder of European Crypto Initiative, told Cointelegraph.
“The fact that smart contracts lack such features puts their use and development at risk. They may be perceived as inconsistent with regulatory requirements.”
“The problem is if the scope of Article 30 were to be extended beyond the application of smart contracts in this narrowly defined context, and on public permissionless networks. It becomes not only problematic but almost impossible for such protocols to comply,” he said.
Per Voloder, another concern is whether these rules could spill over into decentralized finance (DeFi). “As we do not have a DeFi regulation, this is a question that will need an answer over the next 18 months as the EC prepares its position on DeFi.”
Moreover, kill switches can have errors because of human mistakes and, in smart contracts in general, “as they are rigid, bounded information environments.” This rigidity, plus an automatic feature that triggers a certain outcome following strict rules, could lead to issues like locking up assets, shutting down protocols or even losing funds and important data, said Voloder.
A lot of uncertainty
The Data Act has rules for vendors of an app using smart contracts, or for people whose business involves deploying smart contracts.
According to Markežič, the Data Act might cause such vendors and deployers to be more cautious and consider whether their smart contracts in any way contain a data-sharing agreement. Apps might need to change how they work to meet these rules if their smart contracts share data.
But first, it’s crucial to understand who exactly needs to follow these rules, Markežič said:
Erwin Voloder, head of policy at the European Blockchain Association, told Cointelegraph that Article 30 of the Data Act applies when parties agree to share data using a smart contract, and this contract follows the rules. It should be fine if it’s only for that situation, especially when used on a controlled network where the Data Act’s safety stop can be used.
“Is the regulation even targeted toward DeFi platforms and protocols? […] It should be clarified under what circumstances the ‘access control’ is provided, what, who, why and how the ‘safe termination or interruption’ measure is triggered and how protocols prevent further abusive behavior thereof.”
Markežič stated that, in the past, some changes and terminations were made on a protocol layer as part of the overall governance mechanisms.
A kill switch on the level of a smart contract might lump projects and individuals into “a single point of failure, prescribed by the regulators.”
Therefore, it’s critical that regulators clarify who has the power to use this kill switch.
Crypto community across the globe reacts
The crypto community has already proposed some alternative solutions to bring more legal clarity to smart contracts.
In April 2023, Polygon had already penned an open letter suggesting how to improve Article 30, sating that lawmakers could apply these rules to enterprises only, excluding software and developers, and make clear that smart contracts aren’t “agreements” in and of themselves.
More recently, the European Crypto Initiative and numerous organizations, such as Stellar, Iota, Polygon, Near, Coinbase, Cardano and ConsenSys, have signed an open letter voicing their concerns regarding the Data Act and calling on lawmakers to reconsider and clarify certain aspects.

They argued that the Data Act could potentially clash with the recently agreed MiCA regulation. MiCA, which will come into force in 2024, provides a license for crypto exchanges and wallet providers to operate throughout the EU.
They further claim that European lawmakers deliberately sidestepped the more complex issue of decentralized financial regulation –– an issue the Commission will need to revisit in the coming years.
More harm than good?
The trialogue on the Data Act has been completed, and this means that the text has reached its final version and is likely to be enacted in its current form.
According to Markežič, the new law could affect the European crypto industry and businesses that want to operate in the EU, stating that the Data Act doesn’t give clear details about what use cases the new rules apply to, and that makes the whole industry unsure about what to expect. And this is just the first step in the direction of regulating smart contracts, setting a precedent for forthcoming actions, she said.
The next important step for the community is to work closely with European standardization groups. These groups are responsible for creating the standards that vendors and developers of smart contracts should follow when making agreements to share data, especially given that these vendors will need to make sure their smart contracts broadly align with the scope of Article 30.
According to Voloder, if the Data Act is extended to public networks, it could mean companies leaving the EU, at worst, and “otherwise being pigeonholed into a narrow development trajectory of smart contracts in the best case.”
“The result is capital flight, stifled innovation and a floundering blockchain industry in Europe. At a time when Europe is at the vanguard of the regulatory apex, the timing of such an outcome would be most inopportune.”
Do Kwon, the co-founder of Terraform Labs, has been sentenced to 15 years in prison after pleading guilty to wire fraud and conspiracy to defraud.
In a Thursday hearing in the US District Court for the Southern District of New York, Judge Paul Engelmayer ordered that Kwon serve 15 years in prison for his role in the collapse of Terraform, which wiped out about $40 billion from the crypto market in 2022. He will receive credit for time served in the US and 17 months of pre-extradition custody.
Prior to making his decision on sentencing, Engelmayer heard from some of Terraform’s victims and questioned what kind of justice Kwon might face in his native South Korea, where authorities are also building a case against him.
“I would like everyone to know that I have spent all my time thinking what I could have done, and what I can do,” said Kwon prior to his sentencing, according to Inner City Press. “It’s been four years since the crash, three years since I’ve seen my family. I’d like to [do] my penance in my home country.”
Engelmayer reportedly said the 12-year recommendation US prosecutors had requested the court impose on Kwon was “unreasonable,” while the five years requested by the co-founder’s lawyers “would be so implausible it would require appellate reversal.”
“To the next Do Kwon, if you commit fraud, you will lose your liberty for a long time as you will here,” said Engelmayer, according to Inner City Press. “You have been bitten by the crypto bug, and I don’t think that’s changed. You must be incapacitated. If not for your guilty plea, my sentence would have been higher.”
The judge added, addressing Kwon:
“Your fraud was unusually serious. For four years you publicly lied to the market […] The investors were taking a risk, caveat emptor. But they were not taking the risk of being a fraud victim… What makes what you did so despicable is that you traded on trust.”
Kwon could be extradited to South Korea after serving seven and a half years, where he may complete the second half of his US sentence. He could face up to an additional 40 years in prison in his native country.
Several victims have their say during the sentencing hearing
Prosecutors said at the sentencing hearing that there were about 16,500 victims from the collapse of Terraform, according to claims in the company’s ongoing bankruptcy case. Six of them were allowed to address the court via phone before Engelmayer’s decision, describing their financial losses due to Terra.
“I sold my apartment in Moscow to invest with Do Kwon,” said Tatiana Dontsova, one of the victims, according to Inner City Press. “I moved to Tbilisi. $81,000 turned into $13 in the palm of my hand. Kwon came up with Luna 2, calling it LUNC. He is not showing any responsibility for those who invested. I am now officially homeless.”
Kwon, alleged to have had a role in the 2022 collapse of the Terra ecosystem, was handed over to US authorities in December 2024 after his extradition from Montenegro. His legal team delayed proceedings for months by presenting various challenges in the Montenegrin courts.
With Kwon expected to be in prison for years, the Terraform co-founder became the latest former high-profile cryptocurrency executive to enter a plea deal or be found guilty in US courts.
Former FTX CEO Sam Bankman-Fried is serving a 25-year sentence, former Binance CEO Changpeng Zhao served four months — though was later pardoned by US President Donald Trump — and former Celsius CEO Alex Mashinsky was sentenced to 12 years.
Update (Dec. 11 at 7:35 pm UTC): This article has been updated to include a Thursday policy announcement from Caroline Pham.
The top Republican on the Senate Agriculture Committee said the full chamber could vote on US President Donald Trump’s pick to chair the Commodity Futures Trading Commission “maybe as soon as this afternoon.”
In a prepared statement for a Thursday hearing on CFTC reauthorization, Committee Chair Glenn Thompson said the Senate could vote on Michael Selig’s nomination to chair the agency on Thursday. The potential vote would come just a few weeks after the Agriculture Committee advanced Selig’s nomination to the full chamber, along partisan lines.
According to the Senate’s calendar of business, a vote on Selig’s nomination did not appear on the schedule for Thursday. The chamber is expected to break for the holidays on Dec. 22, giving lawmakers a limited window to confirm the prospective CFTC chair.
Selig, whom Trump nominated as CFTC chair in November following the withdrawal of his former pick, Brian Quintenz, faced lawmakers in a November hearing. The prospective chair said it was “vitally important that [the CFTC] have a cop on the beat” for addressing crypto regulation and enforcement.
Acting CFTC Chair Caroline Pham has been the sole commissioner at the financial regulator for months, following the resignation or departure of every member of its leadership due to their terms expiring. Pham is also expected to leave once the Senate confirms a replacement chair, potentially leaving Selig as the sole member.
Pham is still pushing for crypto in her final days
Although it’s unclear when Pham may leave the CFTC, the acting chair has continued to push the Trump administration’s agenda on digital assets by advocating for policies that favor the industry and bringing executives in closer.
On Thursday, the acting chair said she planned to withdraw the CFTC’s “outdated” guidance on digital assets, claiming it “penalizes the crypto industry and stifles innovation.”
Mexico’s central bank warned in a new financial stability report that “stablecoins pose significant potential risks to financial stability,” citing their rapid growth, links to traditional finance and global regulatory gaps that could fuel arbitrage and magnify market stress.
Stablecoins’ heavy reliance on short-term US Treasurys, market concentration with two issuers controlling 86% of the supply and past depegging episodes with stablecoins underscore how vulnerable the sector remains to stress, according to the Banxico report.
Without coordinated international safeguards, mass redemptions or issuer failures could spill into broader funding markets, the central bank warned.
Banxico also highlighted diverging regulatory approaches as a growing source of risk, noting that frameworks like the EU’s MiCA and the US GENIUS Act impose different reserve, redemption and depositor-protection requirements, creating regulatory gaps that could incentivize arbitrage across jurisdictions.
Banxico acknowledged that stablecoins can improve settlement efficiency, reduce transfer costs and support remittances and liquidity in decentralized finance. However, it plans to keep a cautious distance between the traditional financial system and virtual assets, citing their potential to cause stress in broader markets.
Crypto adoption in Mexico is relatively low. According to Chainalysis’ Global Crypto Adoption Index, the country fell to 23rd place in 2025 from 14th place in 2024 in the adoption ranking.
The central bank’s warning reflects Mexico’s broader cautious stance on crypto. Despite the rise of exchanges like Bitso, the country has not introduced significant new digital-asset legislation and still relies on its 2018 Fintech Law as the primary regulatory framework.
Brazil and Argentina lead Latin America in crypto adoption
While Mexico’s central bank maintains a cautious stance on digital assets, other Latin American countries have embraced adoption.
Chainalysis’ 2025 Geography of Crypto Report shows that Latin America generated nearly $1.5 trillion in crypto transaction volume from July 2022 to June 2025, with monthly activity increasing to almost $88 billion by December 2024 from $20.8 billion in mid-2022. Several months in late 2024 and early 2025 consistently exceeded $60 billion.
According to the report, Brazil led Latin America by a wide margin, receiving $318.8 billion in crypto value from July 2022 to June 2025, nearly one-third of all activity in the region, while Argentina ranked second with $93.9 billion in transaction volume.
The central banks of the two leading countries are also taking a more proactive stance in regulating digital assets.
In November, Brazil’s central bank finalized rules that place crypto companies under banking-style supervision, including treating stablecoin transactions and certain self-custody wallet transfers as foreign exchange operations.
