Wirex announced the launch of a zero-knowledge proof based noncustodial crypto debit card service called W-Pay.

Wirex’s new decentralized solution utilizes zero-knowledge technology and is built on Polygon’s Chain Development Kit, promising increased scalability and security. Polygon’s CDK has been built with ZK-proofs in focus, enabling companies and users to develop their own ZK-powered layer-2 rail.

ZK-proof-based scalability solutions have become popular in the crypto space as the ZK protocol allows one party to prove to another party that something is true without disclosing any details about the claim itself. Over time, Ethereum and the likes of Polygon have seen the most development around ZK-proofs.

W-Pay offers a range of ground-breaking features that enable noncustodial wallets and decentralized applications to issue crypto debit cards. The firm claimed the decentralized approach would eliminate third-party risks and ensure account owners retain sole control over their money.

Some key features of W-Pay include swift and secure transactions through the integration of ZK technology, Ethereum Virtual Machine compatibility and account abstraction, which is a feature that streamlines transaction processes by eliminating inherent complexities.

The ZK-proof-based decentralized solution enables card transactions up to a predetermined limit and supports the integration of DApps and noncustodial wallets with conventional payment rails. The firm said W-Pay will usher in a new era of on-chain card payment services.

Wirex created the first payment card with crypto functionality in 2015, enabling users to interchangeably utilize digital and fiat money in daily transactions. Wirex claims to have a customer base of over six million and is a principal member of Visa and Mastercard.

OKX pleads guilty, pays $505M to settle DOJ charges

Published

on

OKX’s operating company, Aux Cayes FinTech Co. Ltd, has pleaded guilty to running an unlicensed money-transmitting business and agreed to a $505 million settlement with U.S. authorities. The settlement includes $84 million in penalties and the forfeiture of $421 million in transaction fees, mostly from institutional clients. The charges stem from legacy compliance gaps that allowed some U.S. customers to trade on the platform despite restrictions.

According to the U.S. Department of Justice, OKX knowingly violated anti-money laundering laws, facilitating over $5 billion in suspicious transactions. Investigators also found that the exchange advised users on ways to bypass compliance checks, further aggravating the violations. However, no allegations of customer harm or charges against OKX employees were filed.

The breaches reportedly occurred between 2018 and early 2024, even though OKX had policies preventing U.S. customers from accessing its services since 2017. Acting U.S. Attorney Matthew Podolsky emphasized that financial institutions operating in the U.S. must comply with regulations and that the penalties serve as a warning to others. The FBI also condemned the company’s actions, stating that regulatory breaches would not be tolerated.

OKX has committed to strengthening its compliance framework and hiring a consultant to address past shortcomings. CEO Star Xu stated that the company aims to become a leader in regulatory compliance across global markets. Despite the hefty settlement, OKX maintains that its U.S. customer base was minimal and has since been removed from the platform.

South Dakota lawmakers effectively kill proposed Bitcoin bill

Published

on

South Dakota lawmakers have effectively blocked a bill that would have permitted the state to invest in Bitcoin. During a House Commerce and Energy Committee meeting, legislators voted to defer House Bill 1202 to the 41st day of the session, a procedural move that ensures its failure since the legislative session only lasts 40 days. The bill, introduced by Representative Logan Manhart, sought to amend the state’s public funds classification to allow up to 10% investment in Bitcoin.

Despite the setback, Manhart has stated that he plans to reintroduce the bill in 2026. South Dakota’s attempt follows similar initiatives in other states, including North Dakota, Montana, and Wyoming, which also failed to pass Bitcoin reserve bills. However, states like Florida, Arizona, and Kentucky are still considering legislation related to Bitcoin investments. These efforts reflect a broader trend among U.S. states exploring digital assets as part of their financial strategies.

The push for state-level Bitcoin reserves gained momentum following U.S. President Donald Trump’s proposal to establish a national Bitcoin stockpile. In a recent executive order, Trump suggested forming a working group to study the feasibility of such a reserve. However, legal challenges have emerged regarding the constitutionality of many of his executive actions, casting uncertainty over their implementation.

With the SEC recently closing investigations into some crypto firms, regulatory sentiment in the U.S. appears to be shifting. While South Dakota’s bill failed, the broader discussion on Bitcoin as a state-held asset continues across the country. The increasing interest from lawmakers indicates that digital assets could still play a role in state-level financial strategies in the coming years.

Ethereum’s favorable risk-return ratio has traders ‘insanely bullish’ on ETH price

Published

on

A crypto analyst has expressed strong bullish sentiment on Ethereum (ETH), citing a highly favorable risk-reward ratio. The analysis highlights that ETH is only 18% above its 200-week exponential moving average (EMA), a level historically associated with price rebounds. The potential upside for ETH is estimated at 200%, with a worst-case drawdown of just 20%. Additionally, technical indicators, including an ascending channel and a liquidity cluster above $4,000, suggest that the price could be gearing up for a significant breakout.

Further on-chain data from Glassnode supports this outlook, revealing strong accumulation at key price levels. Investors have been purchasing ETH heavily around $2,632, with a larger cluster at $3,150, indicating confidence in further price appreciation. This trend suggests that rather than exiting positions, market participants are averaging down, reinforcing the bullish narrative.

Meanwhile, analysts point to Ethereum’s increasing buy pressure compared to Bitcoin. On-chain data from CryptoQuant shows ETH’s taker buy-sell ratio rising while BTC’s declines, signaling stronger buying momentum for ETH. Historically, such trends have allowed ETH to outperform Bitcoin in the short term. However, technical risks remain, with a need to maintain support above $2,600 to avoid a shift in market sentiment.

Despite short-term volatility, ETH’s overall market structure appears robust, with analysts predicting new highs in the coming months. The current accumulation phase and liquidity positioning indicate that Ethereum may see a significant upward move if key resistance levels are broken. However, investors remain cautious, monitoring broader market conditions and potential bearish signals.
