Cardano faces renewed scrutiny after on-chain researcher Masato Alexander alleged that founding-linked wallets moved more than 1.5 billion ADA during the 2021 bull market, reviving debate over early token allocations, founder influence and transparency in one of crypto’s largest proof-of-stake networks.Alexander, an NFT creator and blockchain analyst, published a transaction-tracing thread this week arguing that large ADA flows in 2021 can be linked more directly to Input Output Global-related stake-pool pledges than earlier community claims had shown. His work centres on one transfer of about 925 million ADA and nine transfers of 20 million ADA each, alongside other flows he says point towards a common funding source. The analysis suggests the path between the questioned transfers and IOG-linked pools may be as short as one to seven hops, rather than the roughly 40-step trail cited earlier.
The allegation has gained traction because the period under review coincided with ADA’s strongest market cycle. The token reached an all-time high of about $3.09 in September 2021, before losing more than 94 per cent of its value. ADA was trading near 17 cents at the latest quote, with a market capitalisation of about $6.2 billion and more than 36 billion coins in circulation, leaving investors sensitive to claims that large insider-linked movements may have occurred near peak valuations.
The public data, however, does not by itself establish that Charles Hoskinson, IOG or any specific founding entity sold the tokens. Blockchain records can show transaction ancestry, common funding sources and wallet movements, but they cannot reliably identify every beneficial owner without off-chain records, exchange information or contractual documentation. Alexander has framed his work as a best-effort inquiry and invited corrections to the data or methodology.
Hoskinson, Cardano’s co-founder and the chief executive of IOG, had not issued a detailed public response to the latest tracing claims at the time of writing. The Cardano Foundation said it had no insight into the IOG-related transactions referenced in the thread, while adding that it had no reason to assume anything other than professional conduct by the other founding entities, including Hoskinson. The foundation also stressed that Cardano has three distinct founding organisations.
The dispute touches a long-running area of sensitivity for Cardano: its original distribution. At launch, 25.9 billion ADA came from public sales, while 5.18 billion ADA was allocated to founding ecosystem entities under a technical and business development pool. IOHK, now IOG, received about 2.46 billion ADA, EMURGO about 2.07 billion ADA, and the Cardano Foundation about 648 million ADA. Those figures mean any claim involving billion-token flows can quickly become a governance and market-confidence issue.
The latest claim is separate from the 2025 controversy over unredeemed ADA vouchers, though it lands in the shadow of that dispute. A forensic review released last year found no evidence of misconduct in the voucher programme and said 99.7 per cent of ADA sold through the programme had been redeemed by value. That review addressed allegations involving roughly 318 million ADA in unredeemed vouchers, not the separate 1.5 billion ADA movement now being debated.
Cardano’s governance transition has added to the pressure. The network has been working through a more decentralised decision-making model involving delegated representatives and treasury proposals, while ecosystem groups debate funding, infrastructure and communications strategy. That structure has given token holders more formal channels to challenge leadership narratives, but it has also made public disputes more visible.
The market impact of the allegation remains difficult to isolate. ADA had already been under pressure from weak broader risk appetite, lower activity than rival smart-contract chains and concerns about the pace of decentralised finance adoption. Cardano still promotes its peer-reviewed research model, proof-of-stake design and formal methods as differentiators, while critics argue that developer mindshare, liquidity and application usage have lagged behind rival networks.
