# Mainnet and Multi-Chain RPC Tasks — Completed (In-Repo)

**Last Updated:** 2026-02-16  
**Purpose:** What was completed for tasks that require Mainnet and other RPCs; what to run from a machine with network access.

---

## Completed in-repo

1. **Infura: API key + secret**
   - `INFURA_PROJECT_ID` and `INFURA_PROJECT_SECRET` set in `smom-dbis-138/.env`; `ETHEREUM_MAINNET_RPC` points to Infura.
   - Scripts use `scripts/lib/infura.sh` to build Infura RPC URLs (with Basic Auth when secret is set).
   - Relay uses `INFURA_PROJECT_SECRET` for Mainnet Basic Auth.

2. **Mainnet deploy script**
   - `smom-dbis-138/scripts/deployment/deploy-all-mainnet.sh` now uses Infura with Basic Auth when `INFURA_PROJECT_SECRET` is set (no longer falls back to public RPC for broadcasts).

3. **RPC verification script**
   - `smom-dbis-138/scripts/deployment/verify-all-rpcs.sh` tests Mainnet, Chain 138, and all configured Infura/other RPCs. Run from a machine with outbound HTTPS to Infura/public RPCs to confirm connectivity.

4. **Balance and gas check**
   - `smom-dbis-138/scripts/deployment/check-balances-gas-and-deploy.sh` (no `--deploy`): uses Infura Gas API when `INFURA_PROJECT_ID` is set; reports deployer balance on Chain 138 and other chains. Chain 138 OK; other chains show INSUFFICIENT until deployer is funded with that chain’s native gas token.

5. **Mapper tasks**
   - `./scripts/run-remaining-mapper-tasks.sh`: config validation passed; Chain 138 on-chain check 46/46 contracts present.
   - `./scripts/complete-all-mapper-operator.sh`: runs the above and, when `smom-dbis-138/.env` has bridge addresses and `PRIVATE_KEY`, runs `complete-config-ready-chains.sh` to add destinations.

## Run from a machine with Mainnet/Infura access

From a host that can reach Infura and other RPCs (e.g. your LAN or a server with outbound HTTPS). **Run each command separately** (after the first, you are already in `smom-dbis-138`):

```bash
# From repo root: verify all RPCs (Mainnet, 138, Polygon, Base, etc.)
cd smom-dbis-138 && bash scripts/deployment/verify-all-rpcs.sh

# Balance check (report only; no deploy) — run from repo root, or if already in smom-dbis-138 just:
bash scripts/deployment/check-balances-gas-and-deploy.sh

# Mapper validation + operator checklist (from repo root)
cd /path/to/proxmox && ./scripts/complete-all-mapper-operator.sh
```

## Remaining (require gas and keys on each chain)

- **Mainnet:** Fund deployer with ETH; then run `deploy-all-mainnet.sh` or Trustless/CCIP deploy scripts as needed.
- **Gnosis (100), Celo (42220), Wemix (1111):** Deploy CCIP WETH9/WETH10 per chain (xDAI/CELO/WEMIX for gas), add destinations, fund bridges with LINK. Runbook: [CONFIG_READY_CHAINS_COMPLETION_RUNBOOK.md](CONFIG_READY_CHAINS_COMPLETION_RUNBOOK.md).
- **Other chains (Polygon, BSC, Avalanche, etc.):** Fund deployer with that chain’s native token, then run the relevant deploy script with the chain’s RPC.
