Harry Chun Tak Yeh, founder of Quantum Fintech Group and a longtime figure in the Fantom ecosystem, died after a reported fall from the Jade Park residential tower in Asunción, Paraguay, with authorities still investigating how it happened.
Summary
- Paraguayan authorities are investigating Harry Yeh’s death after a fall from Jade Park’s 30th floor.
- Police found the 30th floor apartment linked to Yeh open and disturbed during their investigation.
- Authorities have not determined whether the fall was accidental, suicide related, or involved another person.
- Yeh founded Quantum Fintech Group and became closely associated with Fantom ecosystem project Tomb Finance.
- Yeh’s website claimed his funds and partners managed over $2 billion, without independent verification publicly.
Police were called to the building at about 4:30 a.m. on Aug. 7 and preliminarily identified the victim as Yeh.
The investigation remains open. Paraguayan police and prosecutors have not publicly classified the death as an accident, suicide or an act involving another person. The latest local reporting reviewed on Aug. 10 said forensic work and an autopsy were being used to establish the cause and circumstances.
Harry Yeh death probe centers on two apartments
Prosecutor María del Carmen Palazón joined Criminalistics and Homicide officers in examining an apartment on the 30th floor where Harry Yeh was believed to have stayed. Investigators found its doors open and the interior heavily disturbed, with nobody inside, according to a local report.
Police also examined another apartment on the 27th floor. Homicide chief Abel Cantero said evidence collected from both properties was transferred to the Public Prosecutor’s Office. Local reports said Yeh’s body was found without clothing, but authorities have not publicly explained whether that detail has any relevance to the cause of death.
Police have not established how the fall occurred
Asunción police director Francisco Ávalos said investigators were still at an early stage and could not determine how Yeh fell. Authorities were considering multiple possibilities rather than treating any single explanation as established. Prosecutors also sought authorization to search the apartment more thoroughly as they attempted to reconstruct Yeh’s movements before his death.
No official finding cited in the latest Paraguayan reporting has accused another person of involvement. Likewise, reports describing the apartment as disturbed do not by themselves establish robbery, assault or a crypto related crime. The body was transferred to Paraguay’s Judicial Morgue for an autopsy and forensic examination.
Yeh became closely tied to Fantom through Tomb Finance
Harry Yeh founded and managed Quantum Fintech Group, an investment business focused on cryptocurrency, blockchain and digital assets. His own profile says he also founded and seeded LIF3 and L3 Reserve and had been active across crypto investment and trading.
His connection to Fantom was particularly visible through Tomb Finance. A 2021 Fantom Foundation post said Tomb operated under Yeh’s oversight after he assumed direction of the project. His website separately describes an investment ecosystem focused primarily on Fantom based projects.
That ecosystem later changed substantially as Fantom evolved into Sonic. As previously reported inthe Fantom to Sonic transition, the FTM to S migration began in early 2025 at a 1:1 ratio. More recently,Sonic’s leadership restructuring saw several longtime figures step away from its board in June 2026.
$2 billion investment figure remains self reported
Harry Yeh’s biography says funds and assets managed by him, Quantum Fintech Group and partners “exceeded $2B USD.” An older profile reported that Yeh and his team said their network managed more than $2.4 billion. Neither source provides independently audited documentation supporting those figures, so they should be treated as claims rather than verified assets under management.
The next confirmed development is expected to come from Paraguay’s forensic and prosecutorial process. As of Aug. 10, the latest authoritative local reporting still described the autopsy and evidence review as pending and did not establish what caused Yeh to fall. Any claim that the death resulted from murder, suicide, robbery or a crypto related attack therefore remains unconfirmed.
