Proof Crater

Proof Crater is a privacy-first commitment engine designed to handle high-stakes blockchain data and private asset distributions.

Our flagship ZK-Vault functionality is built specifically for secure, non-custodial payouts. Organizations commit a Merkle root of payment obligations (such as salaries or airdrops) and lock funds into a secure vault. Using browser-side ZK-proof generation, recipients can claim their funds to any clean address via a relayer. Because the proofs are built locally, Proof Crater never sees your secrets, and the blockchain never links the depositor to the final recipient.

Beyond distributions, Proof Crater acts as an independently verifiable snapshot registry. It captures historical blockchain state at specific blocks and anchors them as tamper-evident references—critical for audits, governance, and compliance.
