# Defender Deployment - Ready Status

**Date**: 2025-12-11
**Status**: ✅ Scripts Updated - Configuration Needed

---

## ✅ What's Been Done

### Deployment Scripts Updated

Both deployment scripts have been updated to use Defender:

1. **DeployMainnetTether.s.sol**
   - Now checks for `DEFENDER_ADMIN` first
   - Falls back to `TETHER_ADMIN` if Defender not set
   - Logs Defender admin address on deployment

2. **DeployTransactionMirror.s.sol**
   - Now checks for `DEFENDER_ADMIN` first
   - Falls back to `MIRROR_ADMIN` if Defender not set
   - Logs Defender admin address on deployment

---

## ⚠️ Configuration Required

### 1. Set Defender Admin Address

Add to `.env` file:
```bash
DEFENDER_ADMIN=0x...  # Your Defender relayer address
```

**How to get Defender address:**
1. Go to OpenZeppelin Defender: https://defender.openzeppelin.com/
2. Create or select a relayer
3. Copy the relayer address
4. Add to `.env` as `DEFENDER_ADMIN`

### 2. Update RPC URL

The current RPC URL has a placeholder. Update in `.env`:
```bash
ETH_MAINNET_RPC_URL=https://eth-mainnet.g.alchemy.com/v2/YOUR_ACTUAL_API_KEY
```

Replace `YOUR_ACTUAL_API_KEY` with your real Alchemy API key.

## 🚀 Deployment Commands (After Configuration)

Once `.env` is configured:

### Deploy MainnetTether
```bash
cd /home/intlc/projects/smom-dbis-138
source .env

forge script script/DeployMainnetTether.s.sol \
  --rpc-url $ETH_MAINNET_RPC_URL \
  --private-key $PRIVATE_KEY \
  --broadcast \
  --verify \
  -vvvv
```

### Deploy TransactionMirror
```bash
forge script script/DeployTransactionMirror.s.sol \
  --rpc-url $ETH_MAINNET_RPC_URL \
  --private-key $PRIVATE_KEY \
  --broadcast \
  --verify \
  --via-ir \
  -vvvv
```

---

## ✅ Verification Steps

After updating `.env`:

1. **Test RPC Connection:**
   ```bash
   cast block-number --rpc-url $ETH_MAINNET_RPC_URL
   ```
   Should return current block number.

2. **Verify Defender Address:**
   ```bash
   echo $DEFENDER_ADMIN
   ```
   Should show your Defender relayer address.

3. **Check Deployer Balance:**
   ```bash
   cast balance $(cast wallet address $PRIVATE_KEY) --rpc-url $ETH_MAINNET_RPC_URL
   ```
   Should show sufficient ETH for gas.
