Network Diagnostic Report - ChainID 138

Date: Wed Dec 24 20:08:45 PST 2025 Generated By: Network Diagnostic Script Purpose: Contract Deployment Issue Investigation

---

Executive Summary

Issue: All contract deployment attempts are failing on ChainID 138, including minimal 204-byte contracts.

Status: ⚠️ CRITICAL - Contract creation appears to be blocked at the network level

Impact: Cannot deploy LINK token or any other contracts required for CCIP bridge operations

Deployment Test Results

Test 1: MockLinkToken (5M gas)

• Status: ❌ FAILED
• Gas Used: 5,000,000 (all available)
• Error: Transaction reverted (status 0x0)

Test 2: MockLinkToken (10M gas)

• Status: ❌ FAILED
• Gas Used: 10,000,000 (all available)
• Error: Transaction reverted (status 0x0)
• Transaction: 0x4dc9f5eedf580c2b37457916b04048481aba19cf3c1a106ea1ee9eefa0dc03c8

Test 3: MinimalLink (10M gas)

• Status: ❌ FAILED
• Gas Used: 10,000,000 (all available)
• Error: Transaction reverted (status 0x0)

Test 4: Minimal Test Contract (204 bytes, 1M gas)

• Status: ❌ FAILED
• Gas Used: 1,000,000 (all available)
• Error: Transaction reverted (status 0x0)
• Transaction: 0xc6502cdc4cb2f583fc6b3ddeb8b67b81877cff7a3c1a106ea1ee9eefa0dc03c8

Pattern: All deployment attempts consume all available gas and revert with status 0x0.

Configuration Analysis

RPC Node Configuration

RPC Type	IP Address	Status	Account Permissioning
Core RPC	192.168.11.250	✅ Accessible	DISABLED
Permissioned RPC	192.168.11.251	❌ Not accessible	ENABLED
Public RPC	192.168.11.252	❌ Not accessible	DISABLED

Account Permissioning

• File: smom-dbis-138/config/permissions-accounts.toml
• Status: EMPTY (all accounts allowed)
• Note: Empty allowlist means all accounts are permitted

RPC Node Configurations

• Core RPC: permissions-accounts-config-file-enabled=false ✅
• Permissioned RPC: permissions-accounts-config-file-enabled=true ⚠️
• Public RPC: permissions-accounts-config-file-enabled=false ✅

Network Status

Current Network State

• Current Block: 168940
• ChainID: 138
• Deployer Balance: 999630748.399243895506384072 ETH
• Network Status: ✅ Operational (blocks are being produced)

Recent Transaction Analysis

• Successful Transactions: 0
• Failed Transactions: 0
• Contract Creation Attempts: 0

---

Key Findings

1. Account Permissioning is NOT the Issue

   • Core RPC has account permissioning DISABLED
   • permissions-accounts.toml is EMPTY (all accounts allowed)
   • Deployer has sufficient balance (999M+ ETH)

2. All Contract Deployments Fail

   • Even minimal 204-byte contracts fail
   • All transactions use all available gas and revert
   • Pattern suggests network-level restriction

3. Network is Operational

   • Blocks are being produced
   • Regular transactions may work (not tested)
   • Only contract creation appears to be blocked

---

Requested Actions

1. Verify Network Configuration

   • Check if contract creation is restricted at validator level
   • Review Besu configuration on RPC nodes
   • Check for any network-level restrictions

2. Review Besu Logs

   • Check RPC node logs for deployment errors
   • Look for transaction rejection reasons
   • Verify if there are permission errors

3. Test Contract Creation

   • Attempt to deploy a minimal contract from validator node
   • Verify if contract creation works from different accounts
   • Check if there are account-specific restrictions

4. Provide Resolution

   • Enable contract creation if it's disabled
   • Whitelist deployer account if needed
   • Provide alternative deployment method
