FAQ

Proof of Reserves is an independent technical verification that verifies whether a custodian’s on-chain holdings match their user liabilities. It’s a key measure of transparency and trust, ensuring that platforms are covered by in-scope reserves based on scoped liabilities data. This is crucial for maintaining confidence among users, stakeholders, and regulators in the Web3 space.
Proof of Reserves is essential for centralized exchanges (CEXs), decentralized finance (DeFi) protocols, liquid staking platforms, tokenized asset platforms, and any Web3 projects that hold custodial assets. It’s an important tool for demonstrating reserve coverage and transparency.
Hacken’s PoR technical verification begins with a detailed evaluation of your platform’s assets and liabilities. Using advanced cryptographic methods like the Merkle Tree, we verify your holdings and compare them against user balances. After thorough review and testing, we provide a detailed Proof of Reserves verification report outlining the results and any recommended improvements.
A typical Proof of Reserves technical verification can be completed within 2–3 weeks, depending on the complexity of your platform and the size of the assets being verified. We work closely with you to ensure timely delivery while maintaining the highest level of accuracy.
Yes, user privacy is a top priority. Hacken employs advanced cryptographic techniques, such as Merkle Trees, to safeguard sensitive data while ensuring transparency in the verification process. We verify liabilities and reserves without exposing personal information.
Hacken offers on-demand proof generation, meaning your platform can generate a PoR at any time. While this offers flexibility for exchanges, users verify their assets based on the most recent proof generated, not in real-time. This ensures that the data is up-to-date as per the last proof created by the exchange.
The frequency of PoR generation is at the discretion of the platform. Some choose to conduct PoR technical verifications quarterly, while others may do so monthly or even more frequently, depending on their user base and regulatory demands. Hacken’s on-demand system allows you to generate proofs as often as necessary to maintain transparency.
