🔹 Overview

Zeyo is a privacy-preserving on-chain credentialing system for the Core Blockchain that issues Soulbound Tokens (SBTs) as verifiable badges for validated staking, delegation, and DeFi activities.
Built with Zero-Knowledge Proofs and the ERC-1155 standard, Zeyo enables users to prove their Core ecosystem participation — without compromising privacy — and store their achievements on-chain.

🧠 How It Works

1. Connect Wallet
   Users connect their Core wallet via Reown or MetaMask.

2. Enter Activity
   User enter their onchain activity

3. Activity Verification
   AI Agent calls Core API and validates staking, delegation, or Core DeFi participation.

4. ZK Proof Generation
   If valid, Zeyo generates a zero-knowledge proof verifying activity without revealing wallet data.

5. Mint SBT Badge
   An ERC-1155 Soulbound Token is minted to the user's address.

6. On-Chain Identity
   Badges appear in the wallet and Zeyo dashboard, verifiable across the Core ecosystem.
