What This Skill Does
Queries on-chain blockchain data using the Chainbase API. Covers token holders, wallet balances, NFT ownership, DeFi portfolios, ENS domains, transaction history, and token prices across Ethereum and other EVM chains. Falls back to a SQL interface for custom analytics not covered by fixed endpoints.
Covers a wide range of on-chain queries through a single script interface with automatic fallback to SQL for cases that fixed REST endpoints cannot handle.
When to use it
- Look up top holders of a specific ERC20 token
- Check which NFTs a wallet address owns
- Get current or historical price of a token
- Trace transfer history for USDT or USDC
- Query custom on-chain data with SQL
Example Workflow
Here's how your AI assistant might use this skill in practice.
User asks: Who are the top 10 holders of USDT on Ethereum?
- 1Identify intent as top token holders query
- 2Resolve USDT to contract address 0xdAC17F958D2ee523a2206206994597C13D831ec7 on Ethereum (chain_id=1)
- 3Select endpoint GET /v1/token/top-holders
- 4Run: scripts/chainbase.sh /v1/token/top-holders chain_id=1 contract_address=0xdAC17F958D2ee523a2206206994597C13D831ec7 limit=10
- 5Format results as a table with addresses and balances
A ranked table of the top 10 USDT holder addresses with their respective balances
