AlphaBridge

AI-powered prediction market agent with cross-chain USDC settlement

AlphaBridge analyzes real-time Chinese macroeconomic indicators and generates automated trading signals for Polymarket prediction markets. It combines AI reasoning, on-chain prediction markets, and Circle's CCTP V2 for cross-chain settlement.

Key Features

• 7-Factor Macro Model: CPI, PMI, MLF rate timing, PBOC signals, FX pressure, equity sentiment, capital flows
• Builder Attribution: All Polymarket orders carry builder code for volume tracking + fee revenue
• CCTP V2 Bridge: Burn-and-mint USDC transfers between Arc and Polygon Amoy
• Built-in Monetization: Per-transaction fee tracking for builder revenue sharing
• Real-time Dashboard: Web UI showing market state, predictions, and on-chain TXs

Polymarket Builder Setup

1. Register at builders.polymarket.com
2. Get API Key + Builder Code
3. Set in .env:

   POLY_API_KEY=...
   POLY_API_SECRET=...
   POLY_API_PASSPHRASE=...
   POLY_BUILDER_CODE=0x...
   

CCTP Bridge

The CCTP V2 bridge burns USDC on Arc Testnet and mints on Polygon Amoy:

from circle_app_kit import bridge_arc_to_amoy

result = bridge_arc_to_amoy(
    amount="1",
    destination_address="0x...",
)
# Burn TX confirmed → fetch attestation from iris-api → receiveMessage on Amoy

Note: CCTP V2 depositForBurn uses uint32 for minFinalityThreshold, not uint256.
