Three Years of Proof of Reserves: USD 35.4 Billion in Primary Assets, Up 75% Year Over Year
Today marks the three-year anniversary of our Proof of Reserves (PoR) program, showing USD 35.4 billion in primary assets backing customer funds - a 75% increase compared to the year prior.
Our 36th consecutive PoR report, independently audited and verified by blockchain security firm Hacken, confirms that we maintain over 100% reserves across 22 most commonly traded assets - including BTC at 105%, ETH at 102%, USDT at 106%, and USDC at 100%.
Month after month, these reports reaffirm that accountability in crypto can be proven, measured, and verified.
Transparency You Can Verify
Since launching PoR, we’ve made accountability a measurable standard. Monthly, we publish independently verifiable snapshots, with Hacken reviewing our ownership and asset coverage.
Customer engagement proves the impact: visits to ‘View My Audit’ are up 123% year over year, and ZK verification usage rose 386%.
While industry conversation has eased as markets stabilized, our focus remains on continuous improvement. We’ve added zk‑STARKs for private public on‑chain checks, cut proof files from 2.55 GB to 598 KB, and opened our GitHub so anyone can verify outputs.
Each report is a technical and accountability milestone - proof that transparency can be mathematical, verifiable, and open to scrutiny.
Building Bridges to Traditional Finance
The same transparency that drives our PoR program is shaping our partnerships with traditional finance. Earlier this month, we expanded our collaboration with Standard Chartered into the European Economic Area, allowing institutional clients to trade on our platform while keeping their assets securely custodied with a Global Systemically Important Bank (G‑SIB).
This aligns digital‑asset infrastructure with the security and compliance standards of traditional finance, reflecting growing regulatory trust in our model and a shared commitment to building safer, more transparent markets worldwide.
Security That Backs It Up
Transparency and security go hand in hand. In addition to PoR improvements, we've achieved two globally recognized certifications: ISO/IEC 27001:2022, the world's leading standard for information‑security management, and CSA STAR Level 1, the gold standard in cloud‑security assurance.
These make institutional due diligence easier, offering independent verification from trusted organizations like BSI Group and the Cloud Security Alliance.
Our security framework includes advanced encryption and access controls, monthly PoR audits verified by Hacken, SOC Type 2 compliance, a multi‑billion‑dollar insurance fund*, and SkyNet - our AI‑powered blockchain monitoring tool that detects malicious actors early. We continue to invest in proactive threat detection and risk‑management infrastructure.
Three years of PoR reporting show progress and consistency. What started as a crisis response has set an industry standard. As crypto integrates further with traditional finance, we’ll ensure trust is always verifiable - on-chain and open for all.
