Safeheron launches world’s first open-sourced Intel SGX TEE for Web3

Web3 & Enterprise·May 08, 2025, 6:32 AM

Safeheron, a Singapore-based provider of digital asset self-custody solutions for institutions, has released the world’s first open-sourced trusted execution environment (TEE) related to Intel Software Guard Extensions (SGX). 

 

The Intel SGX is a hardware-based security technology integrated within some Intel processors. It enables application developers to run application code within a secure isolated environment, while preventing access to that code or modification of it by other applications or by the operating system running on that hardware.

Addressing Web3 security & scalability challenges

The Intel SGX enables a TEE, creating a black box for computation. In a blog post published by Safeheron on May 6, the company claimed that its open-source framework “addresses fundamental security and scalability challenges within blockchain and Web3 ecosystems, offering broad potential for deployment across critical scenarios.”

 

The company asserted that the enabling of off-chain TEEs as achieved by its framework, provides for robust blockchain layer-2 scaling, together with privacy-preserving computation. In this way, layer-1 blockchain load can be minimized while enhancing network throughput and verifiability. Safeheron further claimed that this all paves the way for the evolution of a trusted “second execution layer” for decentralized applications.

 

Overcoming Intel SGX complexity

Safeheron developed the TEE framework using C++, a high-level object-oriented programming language. The firm open-sourced the SGX framework due to the significant challenges that developing with Intel SGX poses, arising from its complexity and its engineering overhead.

 

On X, the company claimed that the new framework reduces SGX TEE development complexity, enabling developers to build applications securely for blockchain, cloud security and privacy computing. The framework optimizes advanced cryptographic support, enhanced testing capabilities, high-level API design and secure and encrypted file input and output.

 

Moving beyond closed and opaque systems

Safeheron added that it open-sourced the framework as it had seen concern expressed within the Web3 sector regarding the development of closed and opaque systems, with that concern elevated in relation to ongoing security failures related to Web3 platforms.

 

Safeheron CEO Wade Wang told Cointelegraph that in open-sourcing the framework, the firm is “not threatened by competitors,” but that it is concerned about “slow innovation due to closed systems.”

 

The Singaporean firm was established in 2021. It counts HashKey Capital, Bixin Ventures, Antalpha Ventures, M77 Ventures and Kryptos among its investors. Back in 2022, it raised $7 million in a pre-Series A funding round. At the time, the project’s mission was to make private keys, which individuals use to control and self-custody their digital assets, safer.

 

In terms of products offered, the company markets its MPC Node Suite, a white-label solution that allows clients to build out multi-party computation (MPC) wallet-based applications. It also offers Keyless Wallets that facilitate the development of wallets that don’t require traditional keys. 

 

In February crypto exchange platform BYDFi partnered with Safeheron, leveraging its MPC technology and TEE to build out a key management system.

Metaplanet targeting 21K Bitcoin by 2026

Earlier this month Metaplanet, a Japanese Bitcoin treasury company, said that it was targeting 10,000 Bitcoin in 2025 but the company has raised the bar once again, planning on an acquisition of 21,000 Bitcoin by 2026. On Jan. 5, Metaplanet CEO Simon Gerovich set out a number of objectives for 2025. Among them was a goal for the company to acquire 10,000 Bitcoin in 2025. Gerovich explained that the firm intended to utilize “the most accretive capital market tools available” in order for Metaplanet to meet that target.Photo by André François McKenzie on Unsplash2025-2026 Bitcoin PlanAbout three weeks after the Metaplanet CEO announced that ambition, the company published a press release on Jan. 28 detailing its 2025-2026 Bitcoin Plan, which goes much further.  The plan outlines that 10,000 Bitcoin remains the target for 2025 but that the company has adopted the strategy to accumulate 21,000 Bitcoin by 2026. Gerovich stated that since Metaplanet embraced the Bitcoin Standard on April 8, 2024, the company has experienced exponential growth. Gerovich added: “The market has recognized Metaplanet as Tokyo’s preeminent Bitcoin company, and we are seizing this momentum to solidify our position as a global leader. Our vision is to lead the Bitcoin renaissance in Japan and emerge as one of the largest corporate Bitcoin holders globally. This plan is our commitment to that future.” Adopting MicroStrategy’s Bitcoin playbookMetaplanet has adopted the Bitcoin playbook first pioneered by U.S. business intelligence company turned Bitcoin development firm MicroStrategy. In short, that playbook involves financing Bitcoin purchases with debt. In this way, the company can capitalize on Bitcoin’s historical trend of positive returns over time, using convertible notes and equity to facilitate that.  The practice also creates a feedback loop in so far as MicroStrategy buys Bitcoin, resulting in the Bitcoin unit price increases. The MicroStrategy stock price goes up. Demand for MicroStrategy’s stock and debt goes up, enabling the company to buy more Bitcoin. In its press release, Metaplanet looked back on what had been achieved in terms of its Bitcoin strategy in 2024. In Q4 2024, the company achieved a Bitcoin yield of 309.82%, following on from a 41.7% Bitcoin yield in Q3.  At the close of the year, the Japanese Bitcoin treasury company held 1,761 Bitcoin, purchased at an average Bitcoin unit price of 11.85 million yen ($76,411). Shareholder growth has seen the company surpass 50,000 shareholders. Meanwhile, share trading volume has increased 430x, year-on-year. Since the firm adopted the Bitcoin Standard in April 2024, the company’s market capitalization has grown by 7,000%. Last month, the company celebrated the milestone of having reached a $1 billion market cap. Asia’s largest equity capital raise for BitcoinThe company has dubbed its new plan “The 21 Million Plan.” It will comprise the issuance of 21 million shares by means of moving strike warrants. Gerovich confirmed on X that at $750 million, the plan will involve Asia’s largest-ever public equity capital raise to buy Bitcoin.

Phoenix Group adjusts public trading launch date

Phoenix Group adjusts public trading launch dateWhile experiencing a considerable over-subscription during its pre-market sale on Nov. 21, Dubai-headquartered crypto mining firm Phoenix Group has had to announce a slight delay to its initial public offering (IPO) on the Abu Dhabi Securities Exchange (ADX).Photo by David Rodrigo on UnsplashAccounting for the UAE holiday scheduleIn an announcement published on Tuesday, Phoenix Group revealed that it would list its shares on Dec. 5 instead of the initially planned Dec. 4. The adjustment is attributed to the public holidays declared for the United Arab Emirates (UAE) National Day, celebrated on Dec. 2. The day marks the formation of the UAE, and the Ministry of Human Resources and Emiratisation has designated Dec. 2, 3 and 4 as public holidays for the private sector.“To honor this occasion and ensure comprehensive participation in the IPO, Phoenix Group PLC has rescheduled its listing date to December 5th, 2023,” the announcement states.IPO oversubscriptionAs advised by the company earlier this month, Phoenix Group achieved a successful closure of its IPO on Nov. 18, experiencing an over-subscription of 33 times the available share offering. The offering of 907,323,529 shares witnessed overwhelming demand, with retail investors oversubscribing 180 times and professional investors contributing to a 22-fold over-subscription.Discussions regarding the IPO launch in the UAE have been underway since at least July of this year, although public knowledge of the company’s intentions only became known in recent weeks.Speaking about the objective of the recent public listing, the company’s co-founders, Bijan Alizadeh and Munaf Ali, wrote:“Our aim is to be able to help create a more resilient, inclusive and diversified global blockchain economy, and this IPO is just the first step towards achieving that goal.”725MW mining capacityThe UAE-based mining operator is in the process of developing one of the largest mining facilities in the Middle East. Founded in 2016, the firm now manages 725MW of mining capacity globally, with facilities in the U.S., Canada, Europe and the Middle East.In August, it emerged that Phoenix is a key stakeholder in the development of a $300 million 150MW mining farm project which will be located at the Green Data City in the Omani capital, Muscat.Abu Dhabi-based conglomerate International Holding Company (IHC) acquired a ten percent stake in Phoenix in October. Co-founder Bijan Alizadeh is also a co-founder of M2, an Abu Dhabi-based cryptocurrency exchange that recently received a Multilateral Trading Facility and custodian license from the Abu Dhabi Global Market (ADGM).IPO activityComing off the back of a bear market, IPO activity has been scarce within the crypto space recently. That said, it emerged recently that South Korean cryptocurrency exchange Bithumb is working towards an IPO which it hopes to complete in the second half of 2025. Meanwhile, Ripple Labs has delayed its IPO plans due to regulatory challenges the company is currently dealing with in the U.S. Earlier this month, it emerged that USDC stablecoin issuer, Circle, is looking to launch an IPO in 2024.As Phoenix Group readies itself for public trading, the adjusted launch date aligns with the company’s strategy to maximize participation and capitalize on the UAE’s crypto-friendly environment.

Bhutan Quietly Mining Bitcoin Since $5,000

Bhutan Quietly Mining Bitcoin Since $5,000The tiny nation of Bhutan continues to be full of surprises recently where crypto is concerned, with the latest report suggesting that the kingdom has been mining bitcoin for a number of years already.© Pexels/Pema GyamtshoAccording to a recent report in The Bhutanese, a Bhutan-based publication led by investigative journalist, Tenzing Lamsing, the landlocked nation had been mining bitcoin over the course of a “few years” already, in an effort to diversify its sovereign portfolio.Long-term investment strategyUjjwal Deep Dahal, CEO of Druk Holding and Investments (DHI), told the publication that the venture was part of a long-term investment strategy. DHI is the commercial arm of the Royal Government of Bhutan. It was formed pursuant to a Royal Charter in 2007 with the mandate of making investments on behalf of Bhutan while optimizing usage of resources.The mining activity had centered on Bitcoin although there was a small provision for Ethereum-based mining when Ethereum was a mineable proof-of-work (PoW)-based blockchain network. It’s unclear of the precise timeline but the report outlines that DHI has engaged in the mining space over a number of years, and at a time in which the Bitcoin unit price was as low as $5,000.Exploiting cheap hydroNestled in the Himalayas, Bhutan has considerable hydroelectric resources. Bitcoin mining is ordinarily an expensive exercise but in scenarios where there are plentiful energy resources with a marginally cheaper cost of production than the average, it can be an attractive and profitable enterprise. Dahal outlined that these conditions enabled DHI to reinvest profits back into additional mining equipment.The precise time-frame of DHIs entry into Bitcoin mining is open to speculation. However, we do know that the Bitcoin unit price was last below $5,000 at the onset of the pandemic in March 2020. Prior to that, Bitcoin had risen above $5,000 in April 2019 following an acute bear market in 2018.Crypto lender entanglementsBhutan and DHI hit the crypto radar last month when it was revealed that the kingdom had made significant investments into and out of failed crypto lenders Celsius and BlockFi. Dahal has said that the royal charter-mandated firm had taken out loans with both crypto lenders and had fully repaid those loans. However, that may have been something that happened later than anticipated. The Bhutanese company had a $30 million loan from BlockFi. BlockFi liquidated the Bitcoin collateral associated with that loan in 2022 but it left a shortfall of $800,000. The failed lender subsequently sued DHI. As of an April 13 court filing, BlockFi submitted a voluntary dismissal of the lawsuit to the courts, presumably because the shortfall was subsequently paid by DHI.In the case of Celsius, DHI had withdrawn $65 million from the lending platform prior to it declaring bankruptcy. Consequently, the matter has been the subject of speculation relative to the potential for the Celsius bankruptcy estate to pursue DHI for a clawback of the withdrawn funds.
