What is Moralis Streams API?
The Moralis Streams API allows developers to listen for real-time blockchain events across all major EVM chains, including Ethereum, Polygon, and BSC. By integrating this into your Openclaw Skills workflow, you can automate responses to wallet activity, contract logs, and token transfers without polling the blockchain.
This skill is designed for high-performance applications that require immediate notification of on-chain state changes. It provides a robust webhook delivery system with at-least-once delivery guarantees and built-in security features like signature verification to ensure data integrity.
Moralis Streams API Use Cases
- Real-time monitoring of whale wallet movements and significant transfers
- Automated notifications for ERC20, ERC721, and ERC1155 token events
- Tracking smart contract event logs for decentralized applications (dApps)
- Monitoring internal transactions and native balance changes in real-time
- Building automated trading, security, or compliance bots using Openclaw Skills
How Moralis Streams API Works
- Set up your environment by configuring the MORALIS_API_KEY within your Openclaw Skills workspace.
- Define a stream by specifying target chains (in hex format), wallet addresses, and event signatures (topic0).
- Use a PUT request to initialize the stream, ensuring your webhook endpoint is ready to return a 200 OK response for the mandatory test webhook.
- Receive dual webhook notifications for every event: one unconfirmed (for speed) and one confirmed (for finality).
- Use the built-in SHA3 signature verification to validate that incoming webhooks are legitimately sent from Moralis.
Moralis Streams API Setup
To begin integrating this with your Openclaw Skills, prepare your environment with the following steps:
# Create a .env file if it does not exist
touch .env
# Add your Moralis API Key
echo "MORALIS_API_KEY=your_key_here" >> .env
# Verify your key and list existing streams
curl "https://api.moralis-streams.com/streams/evm?limit=10" \
-H "X-API-Key: $MORALIS_API_KEY"
Moralis Streams API Data Schema & Taxonomy
The skill organizes blockchain event data and stream configurations using a precise schema. Below are the primary identifiers and data types used:
| Component | Format | Example/Allowed Values |
|---|---|---|
| Stream ID | UUID | a1b2c3d4-e5f6-7890-abcd-ef1234567890 |
| Chain IDs | Hex String | 0x1 (Ethereum), 0x89 (Polygon), 0x38 (BSC) |
| Status | Lowercase | active, paused, error, terminated |
| Webhook Signature | SHA3 | x-signature header for security verification |
| Event Types | String | tx, log, erc20transfer, nfttransfer, internalTx |
Moralis Streams API Advanced Features
- Triggers: Enrich webhook payloads with on-chain data like balanceOf or other smart contract view functions
- Listen to All Addresses: Monitor specific events across every single contract on a blockchain simultaneously
- At-Least-Once Delivery: Robust retry logic that ensures your backend receives data even during temporary outages
- Native Balance Tracking: Automatically include native token balance changes (ETH, BNB, etc.) in your webhooks
- Webhook Replay: Easily replay failed webhooks or re-process historical data for analytics via Openclaw Skills
