Repository Update Analysis for ChainID 138

Overview

This document analyzes three repositories that may need updates for ChainID 138:

1. app-ethereum (Ledger hardware wallet support)
2. Cross-Chain-Mirroring (Cross-chain bridge configuration)
3. ethereum-lists/chains (Chainlist.org submission)

---

1. app-ethereum Repository

Repository: https://github.com/Defi-Oracle-Meta-Blockchain/app-ethereum.git
Purpose: Ledger hardware wallet application for Ethereum and EVM-compatible chains
Status: Forked from LedgerHQ/app-ethereum

Analysis

What it does:

• Provides Ledger device support for Ethereum and EVM chains
• Allows users to sign transactions on Ledger hardware wallets
• Supports custom chain configurations

Does it need ChainID 138?

• ✅ YES - If users want to use Ledger devices with ChainID 138
• Ledger devices need the chain configuration to be added to the app

What needs to be updated:

1. Chain configuration file - Add ChainID 138 network definition
2. Network parameters - RPC URLs, chain ID, currency symbol
3. Derivation path - May need custom derivation path for ChainID 138

Files to check/update:

• Network configuration files (typically in src/ or config/)
• Chain definitions
• RPC endpoint configurations

RPC URLs to use:

• Public: https://rpc-http-pub.d-bis.org
• Permissioned: https://rpc-http-prv.d-bis.org

Action Required:

• ⚠️ NEEDS INVESTIGATION - Check if ChainID 138 is already configured
• If not, add ChainID 138 network configuration
• Update RPC URLs to use public/permissioned endpoints

---

2. Cross-Chain-Mirroring Repository

Repository: https://github.com/Defi-Oracle-Meta-Blockchain/Cross-Chain-Mirroring.git
Purpose: Cross-chain bridge and mirroring service configuration
Status: Unknown (needs investigation)

Analysis

What it likely does:

• Configures cross-chain bridge services
• Manages CCIP (Chainlink Cross-Chain Interoperability Protocol) settings
• Handles transaction mirroring between chains

Does it need ChainID 138?

• ✅ LIKELY YES - If it manages bridge configurations for ChainID 138
• Cross-chain services need RPC endpoints to connect to ChainID 138

What needs to be updated:

1. RPC endpoint configurations - Update to use public/permissioned RPCs
2. Chain metadata - Ensure ChainID 138 is properly configured
3. Bridge contract addresses - Verify CCIP router/sender addresses
4. Network parameters - Chain ID, network ID, etc.

RPC URLs to use:

• Public: https://rpc-http-pub.d-bis.org (for general bridge operations)
• Permissioned: https://rpc-http-prv.d-bis.org (for authorized services)

Action Required:

• ⚠️ NEEDS INVESTIGATION - Check repository contents
• Update RPC endpoint references
• Verify bridge contract addresses match current deployment

---

3. ethereum-lists/chains Repository

Repository: https://github.com/ethereum-lists/chains.git
File: _data/chains/eip155-138/chain.json
Purpose: Chainlist.org registry - public chain metadata for MetaMask and wallets

Analysis

Current Status:

• ✅ ChainID 138 ALREADY EXISTS in the repository
• Current entry shows:

  {
    "name": "Defi Oracle Meta Mainnet",
    "chain": "dfiometa",
    "rpc": ["https://rpc.defi-oracle.io", "wss://wss.defi-oracle.io"]
  }
  

What needs to be updated:

1. Chain name - Update to "DBIS Chain" (or keep current if preferred)
2. RPC URLs - Update to:
   • https://rpc-http-pub.d-bis.org
   • https://rpc-http-prv.d-bis.org
3. Explorer URL - Ensure https://explorer.d-bis.org is listed
4. Chain metadata - Verify all fields match our chain-138.json

Comparison:

Current (in repository):

{
  "name": "Defi Oracle Meta Mainnet",
  "chain": "dfiometa",
  "rpc": ["https://rpc.defi-oracle.io", "wss://wss.defi-oracle.io"]
}

Our local config (token-lists/chainlists/chain-138.json):

{
  "name": "DBIS Chain",
  "chain": "DBIS",
  "rpc": [
    "https://rpc-http-pub.d-bis.org",
    "https://rpc-http-prv.d-bis.org"
  ],
  "chainId": 138,
  "networkId": 138,
  "explorers": [{
    "name": "Blockscout",
    "url": "https://explorer.d-bis.org",
    "standard": "EIP3091"
  }],
  "nativeCurrency": {
    "name": "Ether",
    "symbol": "ETH",
    "decimals": 18
  }
}

Action Required:

• ✅ UPDATE NEEDED - RPC URLs are incorrect
• ⚠️ DECISION NEEDED - Chain name: "Defi Oracle Meta Mainnet" vs "DBIS Chain"
• Update RPC endpoints to match current infrastructure
• Ensure explorer URL is correct
