Proof of Reserves (PoR) has emerged as a cornerstone of trust and transparency in the cryptocurrency exchange ecosystem. As digital assets gain mainstream adoption, exchanges that implement PoR distinguish themselves by providing verifiable evidence that user funds are fully backed. This guide explores the top exchanges leading the charge in PoR transparency, their methodologies, and why it matters for your crypto security.
Why Proof of Reserves Matters
- Transparency: PoR allows users to independently verify that an exchange holds sufficient assets to cover liabilities.
- Security: Mitigates risks like fractional reserves or insolvency (e.g., FTX collapse).
- Trust: Builds confidence in platforms by demonstrating accountability.

Q3: Are stablecoins included in PoR?
A: Yes—exchanges like Huobi and Crypto.com verify USDT/USDC reserves.
