# Fireblocks Web3 Integration — Chain 138
|
||||
|
||||
**Last Updated:** 2026-02-21
|
||||
**Status:** Active ✅ (DNS + SSL + NPMplus complete)
|
||||
**RPC Node:** VMID 2301 (192.168.11.232) — dedicated for Fireblocks
|
||||
|
||||
---
|
||||
|
||||
## Overview
|
||||
|
||||
One RPC node is **dedicated for Fireblocks** Web3 integrations: VMID **2301** (`besu-rpc-private-1`, IP **192.168.11.232**). Use it for Fireblocks Console custom network, API, and SDK so Fireblocks traffic is isolated from public and other tenant RPCs.
|
||||
|
||||
**Canonical URLs** (parent repo: proxmox `docs/04-configuration/RPC_ENDPOINTS_MASTER.md`):
|
||||
|
||||
| Use | URL |
|
||||
|-----|-----|
|
||||
| **HTTP RPC (public)** | `https://rpc-fireblocks.d-bis.org` |
|
||||
| **WebSocket RPC (public)** | `wss://ws.rpc-fireblocks.d-bis.org` |
|
||||
| **HTTP RPC (LAN)** | `http://192.168.11.232:8545` |
|
||||
| **WebSocket RPC (LAN)** | `ws://192.168.11.232:8546` |
|
||||
|
||||
**Env vars** (see [.env.example](../.env.example)):
|
||||
|
||||
- `RPC_URL_138_FIREBLOCKS` = `http://192.168.11.232:8545`
|
||||
- `WS_URL_138_FIREBLOCKS` = `ws://192.168.11.232:8546`
|
||||
|
||||

|
||||
|
||||
## 1. Fireblocks Console — Add Chain 138 (Custom Network)
|
||||
|
||||
1. In **Fireblocks Console** go to **Settings → Network Connections → Web3** (or **API** → custom networks).
|
||||
2. **Add custom network** (or “Add chain” / “Custom RPC” depending on UI).
|
||||
3. Use:
|
||||
- **Network name:** e.g. `Chain 138` or `D-BIS 138`
|
||||
- **RPC URL:** `https://rpc-fireblocks.d-bis.org`
|
||||
- **Chain ID:** `138`
|
||||
- **WebSocket URL (optional):** `wss://ws.rpc-fireblocks.d-bis.org`
|
||||
4. Save. Fireblocks will use this RPC for Chain 138 for API and (where supported) Web3 provider.
|
||||
|
||||
---
|
||||
|
||||
## 2. Fireblocks Web3 Provider (SDK) — Custom RPC
|
||||
|
||||
Use the dedicated RPC URL when instantiating the Fireblocks Web3 provider so all Chain 138 traffic goes to the Fireblocks-dedicated node.
|
||||
|
||||
**Example (Node.js / ethers):**
|
||||
|
||||
```js
|
||||
import { FireblocksWeb3Provider } from "@fireblocks/fireblocks-web3-provider";
|
||||
|
||||
const eip1193Provider = new FireblocksWeb3Provider({
|
||||
privateKey: process.env.FIREBLOCKS_API_PRIVATE_KEY_PATH,
|
||||
apiKey: process.env.FIREBLOCKS_API_KEY,
|
||||
vaultAccountIds: process.env.FIREBLOCKS_VAULT_ACCOUNT_IDS,
|
||||
rpcUrl: process.env.RPC_URL_138_FIREBLOCKS || "https://rpc-fireblocks.d-bis.org",
|
||||
});
|
||||
// Chain ID is inferred from RPC (138). Use with ethers.js / web3.js.
|
||||
```
|
||||
|
||||
**Environment variable (recommended):** see [.env.example](../.env.example).
|
||||
|
||||
---
|
||||
|
||||
## 3. Fireblocks REST API — Custom Chain
|
||||
|
||||
For **Create Transaction** and other REST calls that require a chain/network, use Chain ID **138** and ensure the Fireblocks backend is configured to use the custom RPC for 138 (via Console custom network above). No extra code change is needed once the custom network is set in the Console.
|
||||
|
||||
---
|
||||
|
||||
## 4. Hosting (Operator)
|
||||
|
||||
The Fireblocks-dedicated RPC is exposed via NPMplus (VMID 10233) with WebSocket support. DNS and SSL are managed in the **proxmox** repo.
|
||||
|
||||
| NPMplus Proxy Host | Forward To | WebSocket |
|
||||
|--------------------|------------|-----------|
|
||||
| `rpc-fireblocks.d-bis.org` | `http://192.168.11.232:8545` | Yes |
|
||||
| `ws.rpc-fireblocks.d-bis.org` | `http://192.168.11.232:8546` | Yes |
|
||||
|
||||
Operator steps (run from proxmox repo): NPMplus proxy update, SSL request (`CERT_DOMAINS_FILTER=rpc-fireblocks`), Cloudflare A records. See parent `docs/04-configuration/FIREBLOCKS_WEB3_INTEGRATION.md` for full operator steps.
|
||||
|
||||
---
|
||||
|
||||
## 5. Verify RPC and Chain ID
|
||||
|
||||
```bash
|
||||
curl -s -X POST https://rpc-fireblocks.d-bis.org \
|
||||
-H "Content-Type: application/json" \
|
||||
-d '{"jsonrpc":"2.0","method":"eth_chainId","params":[],"id":1}'
|
||||
# Expected: {"jsonrpc":"2.0","id":1,"result":"0x8a"}
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 6. Optional: IP Allowlisting
|
||||
|
||||
If you use **Fireblocks Network Link / Provider Connectivity** and need to allowlist Fireblocks egress IPs, restrict access to the Fireblocks-dedicated node (2301) only. See [Fireblocks Network Link Integration](https://developers.fireblocks.com/docs/network-link-integration-guide-for-provider-connectivity).
