Chain 2138 – Wallet & SDK Config (Defi Oracle Meta Testnet)

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.

1. MetaMask (custom network)

Field	Value
Network name	Defi Oracle Meta Testnet
RPC URL	`https://rpc.public-2138.defi-oracle.io` (or your node)
Chain ID	`2138`
Currency symbol	tETH
Block explorer	`https://public-2138.defi-oracle.io`

JSON (programmatic add): docs/04-configuration/metamask/METAMASK_NETWORK_CONFIG_2138.json.

2. ethers.js (v6 example)

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

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"
