KYC Uniswap integration deployed by PureFi, but not everyone is convinced

Published

on

Zero-knowledge proof (ZK-proof)-based compliance protocol PureFi has launched its Know Your Customer (KYC) and Anti-Money Laundering (AML) integration for the Uniswap decentralized exchange (DEX).

According to a recent announcement shared with Cointelegraph, PureFi claims that its ZK-proof-based KYC and AML integration for Uniswap helps address security and compliance concerns at the protocol level. While the integration can be implemented as part of any Uniswap v4 pool, it was deployed as part of the PureFi DEX Uniswap implementation, replacing standard interfaces with custom compliance routers.

The new decentralized finance (DeFi) platform also introduces level-based verification that scales checks based on transaction volume. Checks go from basic identity and sanctions verification at low volumes to comprehensive KYC with risk-based wallet scoring and real-time monitoring at high volumes.

Not everyone is on board

Hedi Navazan, the chief compliance officer at DEX aggregator developer 1inch Labs, told Cointelegraph that “relying on transaction volume thresholds for progressive compliance enforcement is not, in my view, the right approach.” She shared concerns that such thresholds “fail to capture the broader, more complex risk profile that DeFi and financial ecosystems demand.” She explained:

“Risk assessment should be holistic, considering a variety of factors, not just a singular indicator like transaction volume.”

PureFi CEO Slava Demchuk said that compliance is usually implemented on the front-end (the user interface) and not in the underlying smart contracts on the back-end. The implementation leaves protocols “vulnerable to interface bypass” by bad actors interacting with smart contracts directly. He explained the advantages of the latest PureFi implementation:

“Through the Uniswap v4 hook, we address a long-standing industry-wide blind spot. DeFi needs a middle ground to preserve privacy but align with regulatory standards.”

So far, the exchange is fully operational for the UFI/BNB trading pair; this implementation is meant to be a blueprint on which to build. The modular design allows offchain updates to compliance rules, centralizing the part that must be changed as regulations evolve to allow easier adaptation.

DeFi’s long battle with compliance

Navazan said, “in DeFi, we need a more tailored approach.” According to her, solutions developed for centralized finance are not suitable for its decentralized counterpart due to different priorities:

“Mechanisms that function in centralized finance do not work in the decentralized space, which prioritizes privacy and autonomy,” she added.

Navazan explained that this contrast is “a critical aspect for the crypto and DeFi compliance issue.” She raised concerns that while mixers and privacy coins are on regulators’ watchlists, the use of ZK-proofs might help:

“If zero-knowledge proofs can provide compliant-friendly privacy, regulators might be more likely to allow for privacy-preserving financial instruments.”

She further highlighted that regulatory adoption is “the biggest challenge so far” for DeFi, with regulators equating “financial transparency to seeing every transaction and identity.” She noted that ZK-proofs changed that model and asked if regulators would adopt proofs instead of raw data.

ZK-proofs are a family of advanced cryptographic protocols that allow mathematically proving an aspect of some piece of data without revealing the underlying data. For example, they can show that an entity is not sanctioned and is allowed to use a financial service — without providing the full documentation and private data and while remaining anonymous.

A correct ZK-proof implementation ensures that no additional data is leaked beyond the fact that the proven claim is valid. Those proofs are also efficient data-wise since they can be significantly smaller than the considered data, making them better suited for onchain storage if necessary, as happens with ZK-rollups.

Crypto hacks top $1.6B in Q1 2025 — PeckShield

Published

on

By

Hackers stole more than $1.63 billion in cryptocurrency during the first quarter of 2025, with the Bybit exploit accounting for more than 92% of total losses, according to blockchain security firm PeckShield.

PeckShield reported that over $87 million in crypto was lost to hacks in January, while February saw a dramatic spike to $1.53 billion, largely due to the Bybit attack. That incident was one of the largest crypto thefts to date.

In addition to the Bybit hack, other attacks in February caused $126 million in losses. This included a $50-million exploit targeting Infini, a $9.5-million hack on zkLend and an $8.5-million loss from Ionic.  

Hack-related losses dropped significantly in March, decreasing by 97% from February. PeckShield reported only $33 million in crypto assets were stolen last month. Some funds were even recovered, helping offset damage to users and protocols.

Crypto hacks saw a 131% year-over-year increase

According to PeckShield, the first quarter of 2025 saw more than 60 crypto hacks. The blockchain security firm said the $1.63 billion loss in Q1 2025 represented a 131% year-over-year increase from the first quarter of 2024, when losses reached $706 million.

The largest incident in March was a $13 million exploit involving decentralized finance protocol Abracadabra.Money. PeckShield said the attacker drained 6,260 Ether (ETH) from the protocol on March 25.

The second-biggest incident during the month was an $8.4-million hack on the real-world asset (RWA) restaking protocol Zoth. 

On March 21, security firm Cyvers flagged a suspicious Zoth transaction, an attacker withdrawing $8.4 million from the protocol’s wallets. The assets were converted into a stablecoin and transferred to another address. 

While millions were lost in March, some cases saw assets being returned. On March 7, a crypto hacker who stole $5 million from decentralized exchange (DEX) 1inch returned 90% of the funds

After a smart contract vulnerability was exploited, the DEX offered a 10% bounty to the attacker, worth $500,000, in exchange for returning the rest of the crypto assets. The hacker obliged and sent back $4.5 million to 1inch.

The future of digital self-governance: AI agents in crypto

Published

on

By

Opinion by: Tomer Warschauer Nuni, chief marketing officer of Kima Network

No one should be surprised that the crypto space is actively discussing the new wave of enthusiasm around AI and its limitless uses. According to proponents, AI represents the most promising approach to enhancing blockchain technologies and decentralized applications, driving greater autonomy and efficiency across the ecosystem.

The use of AI agents in crypto trading and interoperability between traditional finance (TradFi) and decentralized finance (DeFi) has been quite fruitful. They also help improve user experience within the ecosystem and play a key role in enhancing the scalability of blockchain networks as they grow.

In December 2024, VanEck reported that AI agents were already numbering 10,000 and that they were expected to reach 1 million in 2025. This projected growth shows how seemingly inevitable this future is for believers and skeptics alike.

The current state of AI agents in the digital world 

It is easy to see why everyone is excited about integrating AI agents into nearly every digital process. They enhance several processes with no or less effort from humans.

Current challenges, however, including the ethical concerns identified by the Vatican, do not allow for their full adoption. Crypto investors also felt the heat after DeepSeek’s release, which led to a massive market loss. This risk-to-reward analysis may well be used to discuss the necessity of AI agents in the crypto industry.

The market capitalization of AI agents in crypto rose 322% in the fourth quarter of 2024, from $4.8 billion to $15.5 billion, indicating that more people in the crypto community are accepting AI. The phenomenon of the absolute autonomy of systems is not so far away if we look at the advantages.

AI agents’ trading, analysis and risk management capabilities are widely reported to be better than those of humans. Every decision made in the market is made quickly and is strongly supported by as much data as possible, reducing human errors that can cause losses. 

There are some good indications of this potential. Edwin is a project that aims to combine AI and decentralized finance, enabling the easy integration of AI agents built on top of frameworks like LangChain and ElizaOS to work with DeFi platforms, including Aave and Uniswap. This makes creating a single interface and securely performing blockchain operations easier, removing the need to learn different protocol integrations.

This allows for a utopia of financial automation, or “DeFAI,” where AI agents can control their financial destiny and manage and control their assets in a highly complex, dynamic environment.

For example, ElizaOS offers a robust multi-agent simulation environment to develop, deploy and manage many autonomous AI agents. It’s a versatile platform that enables these agents to move between various systems while preserving their identity and knowledge toward fully active and self-directed entities in the crypto realm.

AI agents can combine all the functions of TradFi and DeFi without issue. They can cut out the intermediaries in international transactions, improving the speed of handling crypto and fiat financial transactions. They can also enable liquidity providers to manage their stablecoin yields completely automatedly and maximize their yields according to current demand across all blockchains. These integrations are an indication of the endless possibilities in cross-border payment transactions.

In a September 2024 report, the Global Digital Visionaries Council predicted that by 2025, 20% of all financial transactions would be crosschain due to the integration of TradFi and DeFi systems. 

Projects like Virtuals Protocol go further by enabling users to create, own and deploy autonomous AI agents. Although the initial application of Virtuals Protocol is the creation of AI-driven avatars, the protocol offers resources that can be used for autonomous crypto trading, showing the versatility of AI in blockchain ecosystems.

Autonomous market and personalization is also improving with the help of AI. Crypto’s first AI agents index, Cookie.fun — developed by Cookie DAO — provides real-time analysis of agents’ performance, mindshare and engagement across blockchains and social media. The platform lists their market caps and “smart following” to track market trends and provide vital information that investors and projects can use to make better decisions and identify the top-performing agents in the ecosystem.

AlphaNeural provides a decentralized environment for the training, market share and effectiveness of AI models and agents. It also has a marketplace for AI assets and a GPU aggregation network that enables creators to tokenize their work and secure and scale the execution of AI solutions. In this manner, the current opportunities for developing advanced AI tools are open for everyone, which connects AI developers with the crypto ecosystem.

The crypto analyst community is confident that AI technology can improve most blockchain performance metrics. The crypto ecosystem is also experiencing rapid user growth, which means that the level of personalization in customer interactions is also increasing due to the use of AI agents.

The skeptic’s point of view

Nevertheless, many still have different opinions regarding promoting digital autonomy in crypto through AI agents.

One significant concern raised in a case study published by the Wharton School of the University of Pennsylvania is the potential effect on the stock market from the increased risk of market manipulation. In theory, collusion between trading algorithms powered by AI could lead to price inefficiencies that might weaken the efficiency of financial markets. In such cases, the bots could manipulate prices up or down or cause a price surge or crash, eroding the market’s credibility.

Many people have also expressed concerns over relying on AI agents to make decisions because they are prone to hacking. Poorly programmed agents may be unable to resist certain types of cyberattacks, resulting in capital loss.

Without a drastic solution to such threats, risks, and legal and ethical issues, the skeptics will always have a valid argument against integrating AI agents in this area.

AI-driven autonomy

Cryptocurrencies and their supporters have been slow to warm up to AI agents, but they really should, given how useful they’ve been in so many areas. These integrations will likely improve trading, help onboarding from TradFi to DeFi, and offer other features. The utopia of completely autonomous AI control crypto experts describe is just around the corner.

The integration of artificial intelligence and blockchain technology unlocks the door to endless possibilities and may pave the path to a new digital era for humanity and its bots.

Binance ends Tether USDT trading in Europe to comply with MiCA rules

Published

on

By

Binance has discontinued spot trading pairs with Tether’s USDt in the European Economic Area (EEA) to comply with the Markets in Crypto-Assets Regulation (MiCA).

Cryptocurrency exchange Binance has delisted spot trading pairs with several non-MiCA-compliant tokens in the EEA in line with a plan disclosed in early March, Cointelegraph has learned.

While spot trading pairs in tokens such as USDt (USDT) are now delisted on Binance, users in the EEA can still custody the affected tokens and trade them in perpetual contracts.

According to a previous announcement by Binance, the spot trading pairs for non-MiCA-compliant tokens were to be delisted by March 31, which is in line with a local requirement to delist such tokens by the end of the first quarter of 2025.

Delistings on other exchanges in EEA

Binance is not the only crypto exchange delisting non-MiCA-compliant tokens for spot trading in the EEA.

Other exchanges, such as Kraken, have delisted spot trading pairs in tokens such as USDT in the EEA after announcing plans in February.

According to a notice on the Kraken website, the exchange restricted USDT for sell-only mode in the EEA on March 24. At the time of writing, the platform doesn’t allow its EEA users to buy the affected tokens.

Kraken’s delisting roadmap in the EEA only included five tokens: USDT, PayPal USD (PYUSD), Tether EURt (EURT), TrueUSD and TerraClassicUSD.

ESMA doesn’t prohibit custody of non-MiCA-compliant tokens

Binance and Kraken’s move to maintain custody services for non-MiCA-compliant tokens aligns with a previous communication from MiCA compliance supervisors.

On March 5, a spokesperson for the ESMA told Cointelegraph that custody and transfer services for non-MiCA-compliant stablecoins do not violate the new European cryptocurrency laws

On the other hand, the same regulator previously advised European crypto asset service providers to halt all transactions involving the affected tokens after March 31, adding a certain extent of confusion over MiCA requirements.
