Uniswap Labs has released a draft of the code for Uniswap v4, announcing the move in a June 13 blog post from Uniswap’s founder, Hayden Adams. The new code features “hooks,” or plugins that allow developers to create custom liquidity pools. 

Uniswap is the largest decentralized crypto exchange by volume. Its latest version, v3, was deployed on May 4, 2021.

According to the post, v4’s “hooks” feature will allow future developers to create on-chain limit orders, automatic deposits to lending protocols, auto-compounded liquidity provider fees, and many other innovations to the exchange once it is implemented.

Releasing the source code is the first step to launching a new version of Uniswap. The team now plans to converse with members of the Uniswap community and iterate on this base code over time. V4 will be deployed once enough consensus has been built around a final version, but previous versions will still remain available as well.

Uniswap v4’s purpose is to create a way for pool deployers to introduce code that performs a designated action at key points throughout the pool’s lifecycle.

For example, deployers will be able to create time-weighted average market makers that allow users to sell large amounts of crypto in small batches over time. This may help traders to avoid being front-run by Ethereum Virtual Machine bots or to suffer adverse price movements. On-chain limit orders will also be possible, as pools will be able to incorporate logic that lets them fulfill an order only when a token hits a particular price.

Uniswap Labs engineer Sara Reynolds said the new version will allow automated market maker exchanges like Uniswap to develop more rapidly than ever before.

Uniswap Labs’ head of communications, Bridget Frey, echoed this sentiment, stating, “Right now, other people have to build new AMMs to do a lot of this work. Now, what you’ll be able to do is to build your project with a hook contract on top of Uniswap’s security and liquidity in ways that hopefully make the innovation faster and easier to do for all sorts of projects.”

Binance tightens South African compliance rules for crypto transfers

Published

on

Binance is tightening compliance measures for crypto transactions in South Africa, announcing it will fully implement the country’s Travel Rule requirements beginning January 2025. The move aligns with regulations set by South Africa’s Financial Intelligence Centre (FIC) and reflects the exchange’s broader efforts to meet global anti-money laundering standards.

Under the new rules, Binance will require South African users to include verified personal information—such as names, addresses, and account details—when sending or receiving crypto between platforms. These changes are designed to increase transparency and traceability of digital asset transfers, making it harder for illicit actors to exploit decentralized networks.

Binance emphasized that users must complete know-your-customer (KYC) verification before transferring crypto to or from external wallets. Transfers to non-compliant platforms may be restricted or flagged, while internal transfers within Binance or to Travel Rule-compliant entities will remain unaffected.

The announcement follows South Africa’s decision in 2023 to designate crypto as a financial product, placing digital asset providers under the supervision of the FIC. The country has since taken steps to integrate crypto into its formal regulatory structure, including licensing requirements and mandatory reporting obligations.

With enforcement beginning in 2025, Binance urged users to familiarize themselves with the new procedures to avoid disruptions. The exchange also plans to provide additional guidance and tools to help users remain compliant as the deadline approaches.

Ethereum bounces back as market dominance recovers from all-time low

Published

on

Ethereum has staged a notable recovery after recently experiencing its lowest market dominance since its early days. The turnaround comes as ETH surged nearly 4% in the past 24 hours, climbing back above the $3,100 mark and narrowing its underperformance gap relative to Bitcoin.

For much of 2024, Ethereum has trailed behind Bitcoin and a growing wave of altcoins, with its market share dropping below 15% — levels not seen since 2015. The slump was driven by investor focus on Bitcoin ETF momentum, lackluster institutional interest in ETH, and rising competition from layer-1 and layer-2 networks offering faster and cheaper alternatives.

Despite these challenges, Ethereum’s fundamentals remain strong. Data shows a healthy uptick in active addresses, transaction volumes, and total value locked in DeFi protocols built on Ethereum. Additionally, hopes remain high for the approval of a spot Ethereum ETF in the U.S., with analysts suggesting a potential turnaround in institutional flows if approved.

Traders are now watching whether this rebound signals a sustained trend reversal or just a temporary relief rally. With key upgrades and ecosystem developments still in the pipeline, Ethereum’s ability to regain dominance may hinge on reigniting both investor confidence and broader developer activity.

SEC says it won’t re-file fraud case against Hex’s Richard Heart

Published

on

The U.S. Securities and Exchange Commission (SEC) has confirmed it will not pursue a retrial in its fraud case against HEX founder Richard Heart, effectively bringing an end to one of the agency’s high-profile crypto enforcement actions.

The decision follows a recent court ruling that dismissed several key allegations against Heart, including claims that he misled investors and violated securities laws through the promotion and sale of HEX, PulseChain, and PulseX tokens. While the SEC initially signaled it would consider further legal options, it has now opted to forgo additional litigation.

Heart, a controversial figure in the crypto world, had long denied the SEC’s accusations, framing the lawsuit as an overreach by regulators. The agency had alleged that Heart raised over $1 billion from investors while misrepresenting how funds would be used and failing to register the offerings.

With the SEC stepping back, the dismissal marks a rare instance in which the regulator has chosen not to continue a crypto-related fraud case, potentially signaling a reassessment of its approach amid growing legal pushback and mounting scrutiny over its enforcement tactics.

Although the case is now closed, legal analysts suggest the outcome could influence future regulatory efforts and may embolden other crypto founders facing similar challenges. Heart, meanwhile, has positioned the development as a vindication, reaffirming his stance that HEX and related projects were never in violation of U.S. securities laws.
