## Chain 138 RPC — two standards (load-project-env.sh)

| Variable | Use | Canonical value |
|----------|-----|-----------------|
| **`RPC_URL_138`** | Core (admin, deploy, scripts on LAN) | VMID 2101, `http://192.168.11.211:8545` |
| **`RPC_URL_138_PUBLIC`** | Public (bridge, frontend, monitoring, relay) | VMID 2201, `http://192.168.11.221:8545` |

Set in `config/ip-addresses.conf` or `smom-dbis-138/.env`. See [RPC_ENDPOINTS_MASTER](../04-configuration/RPC_ENDPOINTS_MASTER.md).

## Contract addresses — master JSON

| Item | Description |
|------|--------------|
| **Source** | `config/smart-contracts-master.json` (single source of truth; safe to publish) |
| **Bash** | Loaded by `load-project-env.sh` → `load-contract-addresses.sh`; .env overrides JSON |
| **Node** | `require('.../config/contracts-loader.cjs')` → `getContractAddress(chainId, name)`, `loadContractsIntoProcessEnv()` |
| **Docs** | [config/README-CONTRACTS-MASTER.md](../../config/README-CONTRACTS-MASTER.md), [CONTRACT_ADDRESSES_REFERENCE](CONTRACT_ADDRESSES_REFERENCE.md) |
