🔐 Admin Private Key Explanation

How It Works

1. Contract Deployment:

   • PRIVATE_KEY in apps/contracts/.env is used to deploy the contract
   • During deployment, we set adminSigner = 0x93774ed7296373e372547587a3cc6ef3c0cc7b66
   • The contract stores this address

2. Backend Signing:

   • ADMIN_PRIVATE_KEY in apps/backend/.env is used to sign oracle messages
   • The backend creates signatures using this private key
   • The contract recovers the signer address from the signature

3. Verification:

   • Contract recovers signer from signature
   • Checks if recovered address == adminSigner (set during deployment)
   • If match → reward is paid ✅
   • If no match → transaction fails ❌

✅ The Requirement

The address derived from ADMIN_PRIVATE_KEY must match 0x93774ed7296373e372547587a3cc6ef3c0cc7b66

🤔 Your Situation

You said:

• ADMIN_PRIVATE_KEY in backend = PRIVATE_KEY in contracts
• Admin wallet address = 0x93774ed7296373e372547587a3cc6ef3c0cc7b66

Question: Does the PRIVATE_KEY in your contracts/.env correspond to address 0x93774ed7296373e372547587a3cc6ef3c0cc7b66?

✅ If YES:

• Everything is correct!
• ADMIN_PRIVATE_KEY = PRIVATE_KEY is fine
• Proceed with deployment

❌ If NO:

• You need to set ADMIN_PRIVATE_KEY to the private key that corresponds to 0x93774ed7296373e372547587a3cc6ef3c0cc7b66
• PRIVATE_KEY can be different (for deployment)
• ADMIN_PRIVATE_KEY must match the admin wallet

🔍 How to Verify

You can verify by checking what address your PRIVATE_KEY corresponds to:

# Quick check (if you have node installed)
node -e "const { ethers } = require('ethers'); const wallet = new ethers.Wallet('YOUR_PRIVATE_KEY'); console.log('Address:', wallet.address);"

Or check in your wallet:

• Import the private key
• See what address it shows
• Does it match 0x93774ed7296373e372547587a3cc6ef3c0cc7b66?

---

Bottom line: If your PRIVATE_KEY corresponds to 0x93774ed7296373e372547587a3cc6ef3c0cc7b66, then yes, they should be the same! ✅
