|
||
**Last Updated:** 2026-03-27
|
||
**Document Version:** 1.0
|
||
**Status:** Active Documentation
|
||
|
||
---
|
||
|
||
**Purpose:** Wallet and SDK settings for **DeFi Oracle Meta Testnet** (chain ID **2138**).
|
||
**RPC (public, chainlist):** `https://rpc.public-2138.defi-oracle.io`
|
||
**WS (chainlist):** `wss://rpc.public-2138.defi-oracle.io`
|
||
**Explorer (chainlist):** `https://public-2138.defi-oracle.io`
|
||
**Chain ID:** 2138 (`0x85a`)
|
||
**CAIP-2:** `eip155:2138`
|
||
|
||
Use LAN or staging RPC in place of the public URLs when testing privately.

## 2. ethers.js (v6 example)
|
||
|
||
```javascript
|
||
const chain2138Testnet = {
|
||
chainId: 2138,
|
||
name: "DeFi Oracle Meta Testnet",
|
||
nativeCurrency: { name: "testEther", symbol: "tETH", decimals: 18 },
|
||
rpcUrls: {
|
||
default: { http: ["https://rpc.public-2138.defi-oracle.io"] },
|
||
},
|
||
blockExplorers: {
|
||
default: { name: "Quorum Explorer", url: "https://public-2138.defi-oracle.io" },
|
||
},
|
||
};
|
||
|
||
import { JsonRpcProvider } from "ethers";
|
||
const provider = new JsonRpcProvider("https://rpc.public-2138.defi-oracle.io");
|
||
const chainId = await provider.getNetwork().then((n) => Number(n.chainId)); // 2138
|
||
```

||
## 3. Frontend DApp (Vite)
|
||
|
||
- Enable the chain in Wagmi: `VITE_ENABLE_CHAIN2138=true` or `1`
|
||
- Optional overrides: `VITE_RPC_URL_2138`, `VITE_EXPLORER_URL_2138`
|
||
- Trustless bridge L2 side: `VITE_TRUSTLESS_L2_CHAIN_ID=2138` plus lockbox/token env vars (see `smom-dbis-138/frontend-dapp/.env.example`)
|
||
|

|
||
|
||
## 4. Quick verification
|
||
|
||
```bash
|
||
curl -s -X POST https://rpc.public-2138.defi-oracle.io -H "Content-Type: application/json" \
|
||
-d '{"jsonrpc":"2.0","method":"eth_chainId","params":[],"id":1}'
|
||
# Expected: result "0x85a"
|
||
```
