+# 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
+
+---
+
+## 📝 Files Updated
+
+### Chainlist Configuration
+- ✅ `token-lists/chainlists/chain-138.json` - Updated RPC URLs to use public and permissioned endpoints
+
+### Documentation
+- ✅ `explorer-monorepo/docs/CHAINLIST_AND_METAMASK_DATA_FLOW.md` - Updated all RPC references
+- ✅ `explorer-monorepo/docs/CHAINLIST_METAMASK_BLOCKSCOUT_RELATIONSHIP.md` - Updated RPC information
+
+### Token List
+- ✅ Token list is hosted at: https://raw.githubusercontent.com/Defi-Oracle-Meta-Blockchain/metamask-integration/main/config/token-list.json
+- ✅ Token list content is correct and matches local version

+## 🔍 Verification
+
+### Test Public RPC
+```bash
+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
+```bash
+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
+```bash
+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)
+```
