Integration ExampleOne line of code
import { ProofClient } from '@proof-protocol/sdk';

const proof = new ProofClient({
  privateKey: process.env.PRIVATE_KEY
});

// Automatic audit trail generation
const response = await proof.record(
  fetch('https://api.yourbank.com/trade')
);

How It Works

API Call

Your application makes a standard API request

2
proof.record(fetch())

SDK Intercepts

PROOF SDK wraps and captures the request/response

No ICO

No public token sale

B2B Only

Private allocations to qualified companies

Minimum commitment required

Value Through Scarcity

Token value increases over time through deflationary mechanics (50-80% progressive burn per transaction), controlled quarterly allocations, and genuine utility requirements. Yet Technologies manages 100% of token distribution - not all applications are approved.

Simple, Transparent Pricing

Cost-effective alternative to traditional compliance audits.
All plans include blockchain-verified audit trails and GDPR compliance.

Backed by Revenue, Not Speculation

Customer payments fund PROOF token operations. 50-80% of tokens used are permanently burned (deflationary), 20-50% return to treasury (reserves). This creates real utility and sustainable tokenomics backed by actual business revenue. All contracts deployed on Polygon mainnet.
