Paxos executive: recent overminting was an internal operational error; panelists say audits and tokenized reserves could strengthen proof-of-reserves

Summary
Paxos' CEO acknowledged an operational overminting error that was contained within his firm's systems; panelists discussed how the Genius Act, attestations and tokenized on-chain reserves could improve transparency and reduce proof-of-reserves friction.
Chad Cascarella, CEO and cofounder of Paxos, said a recent very large overminting event was the result of an internal operational error and emphasized that the tokens never left the firm's systems.
Asked about what went wrong with the minting process, Cascarella said, "We printed it, actually. Mistake was entirely ours." He explained the error stemmed from an operational/manual cold-minting process that is rarely used and that in this case that process caused an incorrect quantity to be minted. Cascarella said Paxos detected and contained the issue within minutes and then took steps to unwind the excess supply.
Panelists used the incident to discuss proof-of-reserves and resilience. Heath Tarbert, president of Circle, said the "Genius Act" will increase transparency through audits and implementation of reporting standards, but he also suggested future technical approaches such as zero-knowledge proofs combined with AI agents could complement audits. He said, "The Genius Act solves that through transparency, through audits, or sort of the old fashioned way," and added there may be cryptographic and automation enhancements over time.
Cascarella noted current industry practice relies on periodic third-party attestations by auditors that reconcile off-chain bank account balances to on-chain holdings; he said the hard part today is reliably snapshotting the off-chain bank state. He argued that tokenizing underlying reserve assets on-chain would make real-time matching straightforward: "When you start having the underlying assets on chain ... it's very easy to do that match and be able to see it completely directly in real time at all times."
Panelists urged operational and process improvements at issuers and emphasized that blockchain transparency can surface errors quickly. Cascarella framed the episode as painful but as evidence the public ledger enables immediate visibility into issuer operations. The panel recommended stronger operational controls, frequent attestations, and consideration of on-chain tokenized reserves as ways to reduce proof-of-reserves friction going forward.
