Overview
The Web3 Data Skill is a Claude Code skill that covers two Chainbase services:
- On-chain data — query token holders, wallet balances, NFT ownership, ENS domains, address labels, transactions, and more across multiple EVM chains via the Chainbase API.
- Crypto social intelligence — discover trending crypto narratives, search topics, retrieve Twitter/X mentions, and monitor social signals via Tops. No API key required.
Installation
Install the skill via skills.sh:
npx skills add https://github.com/lxcong/web3-data-skill --skill web3-data
npm i -g clawhub
clawhub install lxcong/web3-data
git clone https://github.com/lxcong/web3-data-skill.git
cd web3-data-skill
claude skill install ./skills.sh
Configuration
Set your Chainbase API key as an environment variable (required for on-chain data):
export CHAINBASE_API_KEY="your_api_key_here"
The Tops social intelligence commands do not require an API key and are free to use.
