Cardano Founder Demands Apology from Critics After Audit Confirms 99%+ ADA Vouchers Redeemed

A recent forensic audit and investigative report has exonerated Cardano founder Charles Hoskinson of all allegations tied to the project’s ADA voucher program.

Cardano’s development arm, Input Output Global (IOG), released the 128-page investigative report and forensic audit.

The investigation, carried out by accounting firm BDO and law firm McDermott, Will & Schulte, examined Cardano’s voucher program, its blockchain upgrades, voucher redemptions, and how the ADA linked to unredeemed vouchers was utilized.

Critics alleged that the Cardano founder embedded hidden code in the 2021 Allegra hard fork to manipulate the blockchain. Despite denying the claims, Hoskinson emphasized the need for an audit to dismiss the allegations.

Consequently, the IOG employed the services of BDO and McDermott to investigate the voucher program in May.

Investigation Scope

Their investigation focused mainly on five allegations, including misleading sales practices employed in the voucher program, insiders’ misuse or theft of ADA belonging to voucher holders, and blockchain upgrades blocking ADA redemption.

The investigation also focused on claims that the blockchain upgrade deleted voucher holders’ private keys and that unredeemed ADA was improperly redirected to Cardano Development Holdings (CDH).

Findings

After reviewing thousands of documents, conducting forensic analysis of on-chain and off-chain data, and interviewing 18 current employees, BDO and McDermott concluded that the claims are baseless.

They shared data showing that users successfully redeemed 14,282 vouchers, which represents 25,850,401,508 (roughly 25.9 billion) ADA tokens. This accounts for 99.2% of the total ADA tokens sold in the voucher program.

According to the report, users redeemed 97% of these vouchers by the end of Cardano’s first development phase — the Byron era. Notably, as of August 15, 2025, that figure spiked to 99.2%.

Furthermore, the report indicated that the IOG legally transferred the remaining unclaimed ADA to CDH. The funds were subsequently earmarked for Intersect-powered community projects and ecosystem development.

In conclusion, the report found that the IOG acted diligently in handling the Cardano voucher program.
