Infura RPC Authentication Issue

Date: 2025-12-11 Status: RPC Configuration Issue Identified

❌ Issue

Error: HTTP error 403 with body: private key only is enabled in Project ID settings

Cause: Infura project is configured to require project secret authentication, but only project ID is in the URL.

✅ Solution

Option 1: Use Infura with Project Secret (Recommended)

Update .env to include project secret:

# Current (project ID only)
ETHEREUM_MAINNET_RPC=https://mainnet.infura.io/v3/<INFURA_PROJECT_ID>

# Updated (with project secret)
# With Basic Auth (set INFURA_PROJECT_SECRET in .env; relay builds URL):
# https://<INFURA_PROJECT_ID>:<INFURA_PROJECT_SECRET>@mainnet.infura.io/v3/<INFURA_PROJECT_ID>

How to use: Set INFURA_PROJECT_ID and INFURA_PROJECT_SECRET in .env. The relay service builds the Basic Auth URL from these. Never commit the secret.

Option 2: Disable Private Key Only in Infura

Go to Infura dashboard
Select your project
Go to Settings
Disable "Private Key Only" setting
Save changes

Option 3: Use Alternative RPC Provider

Switch to Alchemy or another provider:

# Alchemy
ETHEREUM_MAINNET_RPC=https://eth-mainnet.g.alchemy.com/v2/YOUR_ALCHEMY_API_KEY

# QuickNode
ETHEREUM_MAINNET_RPC=https://your-endpoint.quiknode.pro/YOUR_API_KEY

# Public RPC (not recommended for production)
ETHEREUM_MAINNET_RPC=https://eth.llamarpc.com

🚀 Deployment Commands (After Fix)

Once RPC is configured correctly:

Deploy MainnetTether

cd /home/intlc/projects/smom-dbis-138
source .env

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

Deploy TransactionMirror

forge script script/DeployTransactionMirror.s.sol \
  --rpc-url "$ETHEREUM_MAINNET_RPC" \
  --private-key $PRIVATE_KEY \
  --broadcast \
  --verify \
  --via-ir \
  -vvvv

📋 Current Status

✅ Deployment scripts ready (EOA admin, no multisig)
✅ Contracts reviewed and ready
⚠️ RPC authentication needs to be fixed
⚠️ Infura requires project secret or setting change

✅ Verification

After fixing RPC, test connection:

cast block-number --rpc-url "$ETHEREUM_MAINNET_RPC"

Should return current block number without errors.
