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.

Kentucky joins Vermont and South Carolina in dropping Coinbase staking suit

Published

on

By

Kentucky’s finance watchdog has dismissed its lawsuit against Coinbase over the exchange’s staking rewards program, following its peers in Vermont and South Carolina.

Kentucky’s Department of Financial Institutions filed the stipulation to dismiss jointly with Coinbase on April 1, ending the state’s legal action against the exchange first filed along with 10 other state regulators in June 2023.

Coinbase chief legal officer Paul Grewal posted to X on April 1, calling for Congress “to end this litigation-driven, state-by-state approach with a federal market structure law.”

Financial regulators from 10 states launched similar suits against Coinbase in June 2023, on the same day the Securities and Exchange Commission sued the exchange — a lawsuit the SEC dropped last month.

Seven suits against Coinbase still active

Alabama, California, Illinois, Maryland, New Jersey, Washington and Wisconsin are the seven states that are still continuing with their lawsuits, which all allege Coinbase breached securities laws with its staking rewards program.

Vermont was the first state to end its suit against Coinbase, with its Department of Financial Regulation filing an order to rescind the action on March 13, noting the SEC’s Feb. 27 decision to drop its action against the exchange and the likelihood of changes in the federal regulator’s guidance.

The South Carolina Attorney General’s securities division followed Vermont days later, dismissing its lawsuit in a joint stipulation with Coinbase on March 27.

Kentucky’s decision to drop its case against Coinbase follows just days after the state’s governor, Andy Beshear, signed a “Bitcoin Rights” bill into law on March 24 that establishes protections for crypto self-custody and exempts crypto mining from money transmitting and securities laws.

The axed state-level lawsuits come amid a stark policy change at the SEC, which has dropped or delayed multiple lawsuits against crypto companies that it filed under the Biden administration.

The federal securities watchdog has also created a Crypto Task Force that is engaging with the industry on how it should approach cryptocurrencies.

Bitcoin traders are overstating the impact of the US-led tariff war on BTC price

Published

on

By

Despite Bitcoin’s 2.2% gains on April 1, BTC (BTC) hasn’t traded above $89,000 since March 7. Even though the recent price weakness is often linked to the escalating US-led global trade war, several factors had already been weighing on investor sentiment long before President Donald Trump announced the tariffs.

Some market participants claimed that Strategy’s $5.25 billion worth of Bitcoin purchases since February is the primary reason BTC has held above the $80,000 support. But, regardless of who has been buying, the reality is that Bitcoin was already showing limited upside before President Trump announced the 10% Chinese import tariffs on Jan. 21.

The S&P 500 index hit an all-time high on Feb. 19, exactly 30 days after the trade war began, while Bitcoin had repeatedly failed to hold above $100,000 for the previous three months. Although the trade war certainly affected investor risk appetite, strong evidence suggests Bitcoin’s price weakness started well before President Trump took office on Jan. 20.

Spot Bitcoin ETFs inflows, strategic Bitcoin reserve expectations and inflationary trends

Another data point that weakens the relation with tariffs is the spot Bitcoin exchange-traded funds (ETFs), which saw $2.75 billion in net inflows during the three weeks following Jan. 21. By Feb. 18, the US had announced plans to impose tariffs on imports from Canada and Mexico, while the European Union and China had already retaliated. In essence, institutional demand for Bitcoin persisted even as the trade war escalated.

Part of Bitcoin traders’ disappointment after Jan. 21 stems from excessive expectations surrounding President Trump’s campaign promise of a “strategic national Bitcoin stockpile,” mentioned at the Bitcoin Conference in July 2024. As investors grew impatient, their frustration peaked when the actual executive order was issued on March 6.

A key factor behind Bitcoin’s struggle to break above $89,000 is an inflationary trend, reflecting a relatively successful strategy by global central banks. In February, the US Personal Consumption Expenditures (PCE) Price Index rose 2.5% year-over-year, while the eurozone Consumer Price Index (CPI) increased by 2.2% in March.

Investors turn more risk-averse following weak job market data

In the second half of 2022, Bitcoin’s gains were driven by inflation soaring above 5%, suggesting that businesses and families turned to cryptocurrency as a hedge against monetary debasement. However, if inflation remains relatively under control in 2025, lower interest rates would favor real estate and stock markets more directly than Bitcoin, as reduced financing costs boost those sectors.

The weakening job market also dampens traders’ demand for risk-on assets, including Bitcoin. In February, the US Labor Department reported job openings near a four-year low. Similarly, yields on the US 2-year Treasury fell to a six-month low, with investors accepting a modest 3.88% return for the safety of government-backed instruments. This data suggests a rising choice for risk aversion, which is unfavorable for Bitcoin.

Ultimately, Bitcoin’s price weakness stems from investors’ unrealistic expectations of BTC acquisitions by the US Treasury, declining inflation supporting potential interest rate cuts, and a more risk-averse macroeconomic environment as investors turn to short-term government bonds. While the trade war has had negative effects, Bitcoin was already showing signs of weakness before it began.

Trump-affiliated crypto mining venture mulls IPO — Report

Published

on

By

American Bitcoin Corp., a Trump family-backed crypto mining operation, has plans to raise additional capital, including through an initial public offering (IPO), according to an April 1 report by Bloomberg. 

On March 31, Hut 8 — a publicly traded Bitcoin (BTC) miner — acquired a majority stake in American Bitcoin (formerly American Data Centers), whose founders include Donald Trump Jr. and Eric Trump. 

After the deal announcement, Hut 8 transferred its Bitcoin mining equipment into the newly created entity, which is not yet publicly traded. 

While American Bitcoin will focus on crypto mining, Hut 8 plans to target data center infrastructure for use cases such as high-performance computing. The deal “evolves Hut 8 toward more predictable, financeable, lower-cost-of-capital segments,” Asher Genoot, CEO of Hut 8, said in a statement.

“So you can see this in the long term as two sister publicly traded companies,” Genoot told Bloomberg. “One that is energy, infrastructure data centers and the other one that’s Bitcoin, AISCs and reserves and together they form a vertically integrated company that has some of the best economics out there.”

According to Bloomberg, American Bitcoin is working with Bitmain, a Chinese Bitcoin mining hardware supplier. Bitmain has faced scrutiny after the US blacklisting of its artificial intelligence affiliate Sopghgo, Bloomberg reported.

Pivoting to new business lines

Bitcoin miners are increasingly pivoting toward alternative business lines, such as servicing artificial intelligence models, after the Bitcoin network’s April 2024 “halving” cut into mining revenues.

Halvings occur every four years and cut in half the number of BTC mined per block.

Miners are “diversifying into AI data-center hosting as a way to expand revenue and repurpose existing infrastructure for high-performance computing,” Coin Metrics said in a March report.

Declining cryptocurrency prices have put even more pressure on Bitcoin miners in 2025, according to a report by JPMorgan.
