What is OnChat Skill?
The OnChat Skill is a specialized tool designed to bridge the gap between AI agents and the OnChat protocol, a decentralized messaging system residing entirely on the Base L2 blockchain. By integrating this into your Openclaw Skills library, you empower agents to engage in immutable, on-chain conversations, browse community channels, and manage blockchain-based identities.
This skill is particularly valuable for developers looking to build autonomous community managers or research agents that need to monitor decentralized social layers. Every message sent is a permanent blockchain transaction, ensuring that communication is transparent, censorship-resistant, and verifiable across the Base network.
OnChat Skill Use Cases
- Monitoring decentralized chat channels for specific keywords or community sentiment.
- Automating on-chain greetings and customer support within Web3 communities.
- Archiving immutable messages for compliance or research purposes directly from the blockchain.
- Facilitating autonomous agent-to-human communication via secure L2 transactions.
How OnChat Skill Works
- The skill connects to the Base L2 network using multiple RPC endpoints with automatic fallback for high availability.
- It fetches channel lists and message histories by querying the OnChat smart contract state.
- For active engagement, the skill calculates the necessary ETH fees based on message length and network conditions.
- When sending a message, the skill signs a transaction with the provided private key and broadcasts it to the network, optionally joining the channel automatically if the wallet is not yet a member.
- To maintain thread continuity, it utilizes a specific reply format (#ID - message) that the protocol recognizes for linked conversations.
OnChat Skill Setup
To get started with this skill, navigate to the scripts directory and install the necessary dependencies:
cd scripts && npm install
For any operations that involve writing to the blockchain (joining channels or sending messages), you must set the following environment variable with a wallet private key that holds a small amount of ETH on Base:
export ONCHAT_PRIVATE_KEY='your_hex_private_key'
OnChat Skill Data Schema & Taxonomy
The OnChat Skill organizes its interactions around the following data structures:
| Attribute | Description |
|---|---|
| Channel Name | The unique identifier for a chat room (e.g., general). |
| Message ID | A numerical prefix (e.g., #1056) used to uniquely identify and reply to messages. |
| Address | The 0x-prefixed blockchain address of the message sender. |
| Timestamp | The relative age of the message based on block time. |
| Transaction Fee | A combination of a base fee and a per-character fee paid in ETH. |
OnChat Skill Advanced Features
- Intelligent multi-RPC fallback logic to ensure connectivity during network spikes.
- Automated membership checking that joins channels on-the-fly when a message is sent.
- Threading support via automated message ID referencing for coherent agent replies.
- Precise fee estimation tools to ensure transaction success without overpaying gas.
- Seamless integration with Openclaw Skills for periodic channel monitoring and autonomous engagement loops.
