AdChain

What is AdChain?

AdChain is a fully decentralized advertising platform built on smart contracts. It connects Web3 advertisers with crypto-native publishers, enabling:

• ✅ Smart contract-based ad payments (no middlemen, fully automated payouts).

• ✅ Instant settlements in USDT (no waiting for withdrawal approvals).

• ✅ On-chain verification of ad impressions & clicks (full transparency).

• ✅ Fraud detection using AI + blockchain oracles (prevents fake clicks).

• ✅ JavaScript Ad Widget for easy integration (just like Google AdSense).

🔹 How AdChain Works (High-Level Architecture)

1️⃣ Advertisers Fund Ad Campaigns

• Advertisers deposit USDT into a smart contract to fund their campaigns.

• They specify target audience, budget, and payout per click.

• Ads are stored on IPFS (decentralized storage).

2️⃣ Publishers Display Ads

• Publishers integrate a JavaScript Ad Widget into their website.

• The widget fetches ads from the blockchain and displays them.

3️⃣ Users Click Ads (Tracked On-Chain)

• When a user clicks an ad, it calls the smart contract to record the click.

• If the click is valid, the smart contract pays the publisher instantly in USDT.

• AI-powered fraud detection checks for bot activity.

4️⃣ Automated Payments & Budget Management

• Each ad has a fixed budget (if it runs out, the ad stops displaying).

• Publishers receive instant crypto payouts (no waiting for monthly payments).

• Advertisers can track spending & performance on-chain.
