RPC Endpoints Update - ChainID 138

✅ Updated RPC Endpoint Information

Correct RPC Endpoints

1. Public RPC (for general use, MetaMask, dApps):

   • URL: https://rpc-http-pub.d-bis.org
   • Status: ✅ Public and accessible
   • Use Case: General public access, MetaMask integration, dApp connections

2. Permissioned RPC (for authorized/private access):

   • URL: https://rpc-http-prv.d-bis.org
   • Status: ✅ Permissioned access
   • Use Case: Authorized users, private access, restricted operations

3. Internal RPC (VMID 2500 - internal network only):

   • URL: http://192.168.11.250:8545 (HTTP)
   • URL: ws://192.168.11.250:8546 (WebSocket)
   • Status: ⚠️ Internal only, NOT public
   • Use Case: Internal services, local development, VM-to-VM communication

❌ Incorrect/Deprecated

• https://rpc-core.d-bis.org - This is internal only and should NOT be used as a public endpoint

🔍 Verification

Test Public RPC

curl -X POST https://rpc-http-pub.d-bis.org \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","method":"eth_chainId","params":[],"id":1}'
# Should return: {"jsonrpc":"2.0","id":1,"result":"0x8a"}

Test Permissioned RPC

curl -X POST https://rpc-http-prv.d-bis.org \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","method":"eth_chainId","params":[],"id":1}'
# Should return: {"jsonrpc":"2.0","id":1,"result":"0x8a"}

Verify Token List

curl -s https://raw.githubusercontent.com/Defi-Oracle-Meta-Blockchain/metamask-integration/main/config/token-list.json | jq '.tokens | length'
# Should return: 3 (WETH9, WETH10, ETH/USD Oracle)
