Infura Settings Fix

Date: 2025-12-11 Issue: Infura RPC requires project secret authentication

📋 Current Configuration (lines 14-19)

From .env:

INFURA_PROJECT_ID or METAMASK_API_KEY: Infura Project ID (set in .env; never commit)
INFURA_PROJECT_SECRET or METAMASK_SECRET: Infura project secret for Basic Auth
INFURA_GAS_API: optional; scripts also use INFURA_PROJECT_ID for Gas API
ETHEREUM_MAINNET_RPC: https://mainnet.infura.io/v3/<INFURA_PROJECT_ID>; relay adds Basic Auth from INFURA_PROJECT_SECRET
Line 19: ETHERSCAN_API_KEY=...

❌ Issue

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

Cause: Infura project has "Private Key Only" setting enabled, which requires project secret authentication.

✅ Solutions

Solution 1: Disable "Private Key Only" in Infura (Easiest)

Go to https://infura.io/
Log in to your account
Select your project (ID set in .env as INFURA_PROJECT_ID)
Go to Settings
Find "Private Key Only" setting
Disable it
Save changes

After this, the RPC URL with project ID will work (or use INFURA_PROJECT_SECRET for Basic Auth):

ETHEREUM_MAINNET_RPC=https://mainnet.infura.io/v3/<INFURA_PROJECT_ID>

Solution 2: Get Infura Project Secret

Go to Infura dashboard
Select your project
Go to Settings
Copy the "Project Secret"

Update .env line 18:

# Set INFURA_PROJECT_SECRET in .env; relay builds Basic Auth URL automatically.
ETHEREUM_MAINNET_RPC=https://mainnet.infura.io/v3/<INFURA_PROJECT_ID>

Solution 3: Use Alternative RPC Provider

Update .env line 18 with alternative 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

🚀 Recommended Action

Easiest: Disable "Private Key Only" in Infura dashboard settings.

Scripts: When INFURA_PROJECT_SECRET is set in .env, deployment and verification scripts now use Infura with Basic Auth automatically (see RPC_URLS_AND_INFURA_ACCESS.md).

This will allow the current RPC URL (line 18) to work without changes.

✅ After Fix

Once RPC is working, deployment will proceed automatically:

# Deploy MainnetTether
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
