Peercast

Peercast is a social prediction network where conversations become prediction markets.

People argue every day on Telegram, Twitter, World, and other social platforms about market moves and outcomes, but most of these disagreements never become verifiable markets. Traditional prediction markets such as Polymarket depend on pre-created listings and liquidity, which makes them great for major events but not for everyday peer-to-peer disputes.

Peercast flips that model. Instead of creating markets first, we let users create predictions directly from social interactions.

In our current demo, users create a prediction inside Telegram. The bot parses the request, both sides confirm the terms, connect wallets, and lock funds into a smart contract deployed on Base Sepolia. Chainlink services then manage the lifecycle: price data is fetched from Chainlink Data Feeds, Automation locks and settles the market, and winners are paid automatically onchain.

We also integrated a Chainlink CRE workflow to verify platform statistics by comparing offchain bot data with onchain contract data and publishing the verification result onchain (i.e., Proof-of-Reserve).

In addition, Peercast uses x402 on Base as the payment rail for chat-native actions and API-triggered flows. This makes it possible to charge for workflow-triggered actions, premium endpoints, or future pay-per-bet/pay-per-settlement services in a lightweight and composable way.

Peercast shows how AI interfaces, Chainlink workflows, and x402 payments can work together to turn social arguments into verifiable, automatically settled prediction contracts.

Peercast consists of four main components.

Telegram & World Bot (Social Layer)
Users initiate predictions directly in Telegram chats. The bot parses commands or natural language requests, confirms prediction parameters, and guides users through the creation flow.

Web Application (Wallet Layer)
A lightweight web interface connects user wallets and allows participants to sign transactions. Users deploy new prediction contracts or join existing ones directly through this interface.

Smart Contracts (Execution Layer)
Smart contracts are deployed on Base Sepolia. A BetFactory contract creates individual prediction contracts that handle escrow, position tracking, price locking, settlement, and payout distribution.

Chainlink + Base Infrastructure
PeerCast integrates multiple infrastructure layers:

• Chainlink Data Feeds for secure price data
• Chainlink Automation for automatic locking and settlement
• Chainlink CRE workflows for platform data verification
• Chainlink Proof of Reserve logic for transparent tracking of funds locked in prediction markets
• Base network and x402 payments for programmable and composable payment flows

This architecture enables social predictions to become fully automated onchain contracts.
