In the wake of recent turmoil in the cryptocurrency industry, trust and transparency have become more critical than ever. With high-profile collapses like FTX exposing severe gaps in financial accountability, users are demanding clearer insights into exchange solvency. Coinbase, one of the leading regulated crypto platforms, has stepped forward with a proactive approach—exploring advanced methods of proof of reserves and investing in the future of on-chain accounting through a new developer initiative.
This move not only reinforces user confidence but also sets a precedent for how crypto companies can combine regulatory compliance with cutting-edge technology to deliver verifiable transparency.

The Need for Proof of Reserves in Crypto
The collapse of FTX was more than just a financial disaster—it was a systemic failure of trust. Customers entrusted their funds to an exchange that lacked transparent oversight, resulting in massive losses when liquidity dried up. One of the core issues was the absence of credible, real-time verification of assets versus liabilities.
This event reignited the conversation around proof of reserves (PoR)—a mechanism that allows exchanges to cryptographically prove they hold sufficient assets to back user deposits. Without such verification, users have no way to confirm whether their balances are truly backed by actual reserves.
Proof of reserves isn’t just about showing wallet balances; it’s about proving ownership and ensuring alignment between on-chain holdings and off-chain liabilities. Various approaches exist, ranging from third-party audits to cryptographic proofs, and Coinbase is now pushing the envelope by exploring next-generation solutions.
How Coinbase Ensures Financial Transparency
As a publicly traded company subject to U.S. securities regulations, Coinbase operates under strict financial reporting standards. It files annual reports with the Securities and Exchange Commission (SEC) and undergoes regular audits by independent accounting firms—practices uncommon in much of the decentralized crypto space.
These traditional financial safeguards are enhanced with cryptographic verification. For example, during audits, external auditors randomly select cold wallet addresses claimed by Coinbase and request a small fund transfer to verify ownership. This process ensures that reported reserves aren’t just numbers on paper but are backed by actual, controllable assets.
Additionally, starting in Q2 2025, Coinbase began classifying crypto assets held for customers as liabilities on its balance sheet—a move aligned with Staff Accounting Bulletin 121 (SAB 121). This accounting standard requires companies to recognize custody obligations, further strengthening transparency and accountability.
Advancing On-Chain Accounting with Zero-Knowledge Proofs
While traditional audits provide a solid foundation, Coinbase recognizes that the future of transparency lies on-chain. The company has announced its exploration of on-chain accounting systems that offer continuous, tamper-proof verification of solvency.
At the heart of this innovation is Zero-Knowledge Proof of Reserves (ZK-PoRL)—a privacy-preserving cryptographic method that allows an exchange to prove it holds sufficient reserves without revealing sensitive information like individual wallet addresses or transaction histories.
ZK-PoRL enables:
- Real-time solvency checks without compromising security.
- User-verifiable proofs that anyone can audit independently.
- Resilience against off-chain risks, such as mismanagement or fraud.
Coinbase envisions a decentralized system where trust is not placed in institutions but in math and code. In their own words:
“We are the only company in the industry that provides both DeFi and tradfi transparency. We are working on a decentralized system that will allow everyone to have complete trust in math.”
This fusion of traditional finance (tradfi) rigor and decentralized finance (DeFi) innovation positions Coinbase at the forefront of a new era in digital asset custodianship.

$500K Developer Grant Program to Fuel Innovation
To accelerate progress in this space, Coinbase has launched a $500,000 developer grant program aimed at supporting individuals and teams building tools for improved on-chain accounting.
The grants will focus on projects that advance:
- Zero-Knowledge PoRL implementations
- Privacy-preserving audit techniques
- Open-source frameworks for real-time reserve verification
- Interoperable standards for cross-platform proof systems
By funding open development, Coinbase aims to create industry-wide standards that benefit all users—not just its own customer base. This collaborative approach could lead to universal protocols for proving solvency, much like HTTPS became the standard for secure web browsing.
Such initiatives underscore a broader shift: from proprietary opacity to open, verifiable systems that prioritize user empowerment.
Industry Response: Binance’s Proof-of-Reserves Initiative
Coinbase isn’t alone in responding to the demand for greater transparency. Binance has also launched its own proof-of-reserves dashboard, starting with Bitcoin holdings. The platform publishes monthly reserve ratios—currently at 101%—and allows users to verify their balances using a Merkle tree structure and a provided Python script.
While this marks progress, critics note that Binance’s approach lacks third-party attestation and comprehensive asset coverage compared to Coinbase’s regulated model. Still, the fact that major exchanges are adopting PoR mechanisms signals a turning point for the industry.
Frequently Asked Questions (FAQ)
What is proof of reserves (PoR)?
Proof of reserves is a cryptographic method that allows cryptocurrency exchanges to demonstrate they hold sufficient assets to cover user balances. It typically involves publishing wallet addresses and using cryptographic signatures to prove ownership.
Why is on-chain accounting important?
On-chain accounting provides real-time, transparent, and independently verifiable records of an exchange’s assets and liabilities. Unlike traditional audits, which are periodic, on-chain systems offer continuous assurance of solvency.
How does Zero-Knowledge Proof of Reserves work?
ZK-PoRL uses zero-knowledge cryptography to prove an exchange holds enough reserves without revealing private data like wallet addresses or transaction details. Users can verify solvency mathematically without compromising security.
Is Coinbase fully transparent with its reserves?
Yes. As a publicly traded company, Coinbase files audited financial statements with the SEC and uses both traditional audits and cryptographic verification. It also plans to enhance transparency through on-chain PoR systems.
Can users verify reserves themselves?
With tools like Merkle tree proofs and open APIs, technically capable users can independently verify if their balances are included in an exchange’s reserve reports. Future ZK-based systems aim to make this process even more accessible.
What impact does SAB 121 have on crypto exchanges?
SAB 121 requires companies holding digital assets for customers to record those obligations as liabilities on their balance sheets. This increases accountability and aligns crypto custody practices with established financial reporting standards.

Final Thoughts: Building Trust Through Technology
The crypto industry stands at a crossroads. On one path lies continued opacity and centralized control; on the other, a future built on transparency, verifiability, and user sovereignty.
Coinbase’s dual strategy—leveraging regulatory compliance while pioneering on-chain innovations like ZK-PoRL and funding developer research—represents a blueprint for sustainable growth. By combining proof of reserves, on-chain accounting, and community-driven development, it’s helping define what responsible crypto stewardship looks like in 2025 and beyond.
As users increasingly demand accountability, the companies that embrace openness—not out of obligation, but as a core value—will lead the next phase of adoption.
