Japan’s Biggest Bank Explores Global Stablecoin Issuance

Aevo, the Singaporean crypto derivatives platform, is gearing up to broaden its ecosystem by allowing other protocols to build on its rollup infrastructure. ‘The future is modular’Currently, Aevo exchange is the sole application on its rollup, but according to Julian Koh, co-founder of Ribbon Finance, the platform's parent protocol, the intention is to open it up for other developers. On Tuesday, Koh retweeted a social media post by the company which stated “The future is modular,” adding the comment “build whatever.” Koh told The Block that "the primary angle here is we are currently built on our own rollup — but Aevo exchange is currently the only app on this rollup. Our plan is basically to open this up for other [developers] as well and build an ecosystem around our exchange."Photo by Shubham Dhage on UnsplashTransitioning to CelestiaAevo, specializing in options and derivatives trading, operates on its own Layer 2 network, built using the OP Stack and running atop the Ethereum blockchain. In a cost-saving initiative, the platform plans to transition to Celestia for storing transaction data in the near term. Celestia launched on mainnet last October with the aim of enhancing blockchain scalability. It’s a modular data availability network which securely scales relative to the number of network users. This expansion is part of a broader roadmap set to be unveiled in the coming weeks, as Aevo looks towards achieving aggressive growth. According to DeFi data aggregator DeFiLlama, Aevo has already been hitting ever higher numbers in recent months. Only two months ago, the protocol had $10 million total value locked (TVL). At the time of writing that metric has increased to $50 million. Last month, the platform achieved a new record-high weekly trading volume level in excess of $500 million. Julian Koh attributes this growth in part to Aevo's yield-bearing balances. Users deposit their crypto, which is then sent to MakerDAO to generate yield. In return, users receive a derivative token to trade on the Aevo platform, providing a mechanism for traders to earn yield while actively engaging in trading. 2023 rebrandRibbon Finance, which initially launched Aevo separately, merged the projects under the Aevo branding in July 2023. As part of the rebrand, an Aevo token will be introduced, with a 1:1 exchange rate for RBN token holders during migration. Post-rebrand, Aevo plans to roll out an incentive program aimed at boosting the platform's metrics.  Looking ahead, Aevo plans to delve deeper into yield offerings, drawing inspiration from Ribbon Finance. The platform aims to launch yield strategies in Q1 of this year, allowing users to lock up their crypto in various setups designed to generate returns, with the tokens being unavailable for trading during this period. One notable strategy that has contributed to Aevo's appeal is the pre-launch trading of upcoming tokens. The platform supports trading for tokens expected to launch soon, often through airdrops, providing an opportunity for traders to hedge against airdrops or lock in specific prices before the official launch. The project team membership draws on past experience at Coinbase, Kraken and Goldman Sachs, with academic backgrounds attained from Stanford, MIT and Cornell University. 

Unprecedented surge in trading volumes on HashKey exchangeHong Kong-based cryptocurrency exchange HashKey has experienced an unprecedented surge in daily trading volumes over the course of the past week, reaching approximately $4.5 billion, a notable increase from its usual levels.Photo by Jungwoo Hong on UnsplashToken rewards programThe surge, highlighted in a report published by The Block on Monday, occurred on Friday, and is being attributed to the company’s token rewards program, according to a spokesperson from HashKey Group.A HashKey Group spokesperson clarified that the surge in volumes was a result of the company’s recent HSK rewards campaigns, which involve the distribution of HSK tokens or EcoPoints. Introduced in April, these incentives were designed to encourage trading activity on the platform. The spokesperson emphasized the company’s commitment to operating within the regulatory framework, stating:“At HashKey, we operate strictly within the regulatory framework, and any actions of misconduct are not tolerated.”Last Thursday, HashKey issued a post on X (formerly known as Twitter), detailing one of its incentive campaigns. The post announced the introduction of a DOT/USD trading pair and encouraged users to explore additional ways to earn through ongoing campaigns. Despite receiving only 15 likes, the post aimed to attract users with the promise of HSK rewards for logging in, trading and participating in the platform’s campaigns.Licensing approval in AugustHashKey had obtained the first license to offer retail crypto trading in Hong Kong in August under the new regulatory regime, with an upgrade of its type 1 and type 7 licenses. Officially opening to traders on November 1, it quickly garnered attention in the crypto community. In the same month, it also launched an app, offering full mobile trading capabilities.While daily trading volumes on Sunday dropped to $275 million, still higher than the usual levels but closer to the volumes recorded in its initial month, the significant spike on Dec. 1 was particularly noteworthy. Comparatively, Binance, the world’s largest crypto exchange, recorded $11.3 billion in volume over the past 24 hours.Wash trading ruled outSpeculation arose on X regarding the possibility of wash trading contributing to the sudden surge in volumes. Wash trading involves intentionally matching a large number of orders to create artificial trading activity. However, HashKey’s spokesperson dismissed these claims, stating that no misconduct has been detected.Justin d’Anethan, Head of Business Development in Asia for Keyrock, a crypto market-making firm, commented on the situation, stating:“Many people in the crypto space assumed wash trading was taking place… But it’s almost unbelievable.”He noted that if one wanted to appear more active, it would be done gradually, rather than in a single surge.Market sentiment and trading volume trendOver the course of the past 24 hours, the Bitcoin unit price has surged from $39,500 to almost $42,000, with Asian trading believed to have contributed significantly to that trading momentum. The overall crypto market capitalization has reached $1.5 trillion for the first time since early 2022. Bitcoin trading volume over the past 24 hours hit $39 billion, with a bitcoin market dominance rate of 51%.

Russia is moving to let ordinary investors gain limited exposure to cryptocurrencies under a draft law that would bring digital assets under the country’s existing financial market framework rather than treating them as a separate category of regulation.Photo by Michael Parulava on UnsplashAnnual retail crypto cap set at $3,800According to a Jan. 13 report by TASS, Anatoly Aksakov, chairman of the State Duma Committee on the Financial Market, said the changes would allow digital assets to become part of everyday life for Russian citizens, but within limits. Under the proposal, annual crypto purchases by retail investors would be capped at 300,000 rubles (roughly $3,800). Aksakov added that professional investors would face no restrictions on crypto investing, noting that digital assets are expected to play a significant role in international settlements. The shift had already been signaled in a December statement from the central bank, cited by Bloomberg. The Bank of Russia said non-qualified investors would be allowed limited access to the most liquid cryptocurrencies after passing a knowledge test. Qualified investors, meanwhile, would be able to buy digital assets without restrictions—excluding anonymous tokens—after completing a risk-awareness assessment. Under the proposals, crypto transactions would be routed through existing market infrastructure. Regulated exchanges, brokers, and trust managers would operate under their current licenses, while custodians and crypto exchange services would be subject to separate requirements. Residents would also be permitted to buy digital assets abroad and transfer their holdings through Russian intermediaries, provided such transactions are reported to tax authorities. The central bank submitted the proposals to the government as part of legislative amendments intended to regulate trading by July 1. It also warned that crypto assets remain high-risk and that investors could face losses. The move marks a notable shift in tone for the Bank of Russia, which in early 2022 pushed for strict limits on the issuance and use of digital assets, likening them to pyramid schemes. Crypto’s role in Russia’s cross-border activity has since expanded amid Western sanctions, including restrictions on access to the SWIFT messaging system imposed on Russian banks after the invasion of Ukraine. Ruble stablecoin booms amid sanctionsThat environment has helped fuel the recent rise of a ruble-backed token used in cross-border flows. A7A5, launched in Kyrgyzstan in January 2025, capitalized on this demand, processing more than $93.3 billion in transaction volume over about a year, according to Chainalysis data. Operating on the TRON and Ethereum blockchains, the token has become a major tool for Russian users navigating banking restrictions. This utility had driven daily transfer volumes past $1 billion by July, according to Elliptic. The activity has persisted despite sanctions and questions about fundamentals, even as the ruble had gained roughly 40% against the dollar by early June, based on Bank of America data cited by CNBC. CoinMarketCap data show A7A5 listed only in a USDT pair on Uniswap V2, while an August Chainalysis report found that activity is concentrated on U.S. Treasury Department Office of Foreign Assets Control (OFAC)-sanctioned services with Russian ties, including Meer, Bitpapa, and Grinex, a confirmed successor to Garantex. Operations on these platforms follow a strict Monday-to-Friday schedule, with volumes surging early in the week and vanishing on weekends.
