# MultiBaas by Curvegrid

> Blockchain middleware for building dApps on Celo with a REST API, smart contract management, and real-time event webhooks.

[MultiBaas](https://www.curvegrid.com/blockchain-platform) by [Curvegrid](https://www.curvegrid.com) is a blockchain middleware platform that wraps your smart contracts in a REST API and advanced feature toolkit. It handles contract management, transaction signing, event indexing, and webhook delivery so you can focus on building your application without managing low-level blockchain infrastructure.

## Key Features

* **[REST API](https://docs.curvegrid.com/multibaas/api/multibaas-api)** — interact with any linked smart contract over HTTPS using standard HTTP clients or the TypeScript/Go SDK
* **[Contract Management](https://docs.curvegrid.com/multibaas/manage-contracts)** — deploy, link, and manage contracts via the dashboard or API; import ABIs from Blockscout or Etherscan by address
* **[Event Webhooks](https://docs.curvegrid.com/multibaas/webhooks)** — receive real-time HTTP callbacks whenever a contract event is emitted on-chain
* **[Cloud Wallets](https://docs.curvegrid.com/multibaas/cloud-wallets)** — server-side signing via Azure Key Vault (AWS KMS and Google Cloud KMS available on request)
* **[Transaction Manager](https://docs.curvegrid.com/multibaas/txm)** — monitors Cloud Wallet transactions and auto-resubmits stuck transactions
* **[Event Indexing](https://docs.curvegrid.com/multibaas/event-indexing)** — built-in indexer with a query and aggregation API for historical event data
* **[Framework Plugins](https://docs.curvegrid.com/multibaas/plugins)** — Hardhat and Foundry Forge plugins to automate contract uploads during deployment

## Getting Started

### 1. Create a Deployment

1. Sign up at [console.curvegrid.com](https://console.curvegrid.com) using Google, GitHub, Microsoft, or email
2. Click **New Deployment**
3. Enter a label, description, and select **Celo** (Mainnet or Sepolia) as the network

The network cannot be changed after a deployment is created. Create separate deployments for mainnet and testnet environments.

Your deployment will be available at `https://<deployment-id>.multibaas.com`.

### 2. Generate an API Key

In your deployment, go to **Admin → API Keys → New Key**.

MultiBaas has multiple key types with different permission levels. The most frequently used are Administrator and DApp User:

| Key Type          | Use Case                                                                     |
| ----------------- | ---------------------------------------------------------------------------- |
| **Administrator** | Server-side code only, full deployment control                               |
| **DApp User**     | Safe to use in frontend apps, read-only and unsigned transaction composition |

Never expose an Administrator key in client-side code.

### 3. Configure CORS (Frontend Apps)

If you are building a frontend application, add your origin at **Admin → CORS**.
