Proof of reserves is crypto’s key to rebuilding trust and transparency

That renewed attention coincided with major policy milestones centered on solvency and disclosure, including the CLARITY and GENIUS Acts passed in July 2025. These laws introduced one-to-one reserve-backing requirements for payment stablecoins and mandated monthly audited attestations — the first federal-level standards that mirror the essence of proof of reserves. These policy milestones show the direction is set; now it’s up to exchanges to lead rather than follow.

The industry’s need for transparency extends beyond PoR. Recent headlines around opaque exchange listing practices — where projects face unclear demands for fees or token allocations — highlight this broader need for accountability. While distinct from proof of reserves, these issues underscore how a lack of transparent standards erodes confidence across the board. PoR, with its cryptographic proofs and independent audits, ensures customer funds remain secure and accessible through mathematically verifiable systems, and that same approach should extend to every aspect of exchange operations.

Credible PoR frameworks rely on technologies, like zk-STARK zero-knowledge proofs and Merkle trees, enabling anyone to verify reserves while keeping their personal data private. The goal is simple: to give customers confidence that their assets are entirely theirs and fully withdrawable. That is the essence of accountability.

The strength of crypto depends on trust, and trust can’t exist without transparency. Every exchange has an opportunity to commit to provable solvency standards, backed by independent audits and open‑source data. Customers, too, can take an active role in examining the facts instead of relying on assumptions — the tools and information are increasingly available.

Transparency alone isn’t enough. To grow sustainably, exchanges must integrate with traditional finance. Leading exchanges are already building these bridges; some have partnered with global systemically important banks to offer institutional-grade custody alongside exchange trading. Others are hiring hundreds of compliance, risk and law enforcement response experts to meet the standards of regulated finance.

We must challenge the crypto industry’s Wild West image. That means not just building bridges to regulated finance but also remembering what we learned during bear markets.

Everyone in this industry has a responsibility to strengthen their systems and take meaningful steps toward greater accountability and integration with the wider, regulated financial world.
