Live Demonstration: Proof Crater ZK Vault

Experience the power of Zero-Knowledge asset distribution. This demo showcases a private payment lifecycle on the Sepolia Ethereum Testnet, featuring a deployed ZK Vault, an on-chain Verifier, and a mock ERC-20 token environment.

How the Demo Works

In a production environment, the secrets (nullifiers and secret keys) are held exclusively by the intended recipients. For this demonstration, we have pre-generated 100 individual commitments and funded the vault with the required mock tokens.

To simulate the withdrawal process, we have exposed the secrets below. By selecting a secret, you can generate a ZK-SNARK locally in your browser. This proof allows you to claim tokens to a fresh address without revealing which deposit you are claiming or linking your identity to the original depositor.

Technical Specifications

• Chain ID: 11155111
• Network: Sepolia Testnet
• Privacy Mechanism: Browser-side ZK-proof generation
• Smart Contracts: Non-custodial vault with Merkle-root commitment verification

Note: While these secrets are public for testing purposes, the underlying cryptography ensures that once a secret is used (the "nullifier" is spent), it cannot be used again, maintaining the integrity of the vault.
So, if you're getting "withdraw impossible" - just pick another secrets.

Available Commitment Secrets

Each entry below represents a unique claimable obligation. Use these values in the withdrawal interface to execute a private transaction.
