Web3 Data Explorer (Chainbase)
Query on-chain data via Chainbase Web3 API and SQL API.
Quick Reference
API Key: Use env CHAINBASE_API_KEY, falls back to demo. If rate-limited, direct user to https://console.chainbase.com to upgrade.
Script: scripts/chainbase.sh <endpoint> [params...]
# Top token holders
scripts/chainbase.sh /v1/token/top-holders chain_id=1 contract_address=0xdAC17F958D2ee523a2206206994597C13D831ec7 limit=10
# Address labels
scripts/chainbase.sh /v1/address/labels chain_id=1 address=0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045
# SQL query
scripts/chainbase.sh /query/execute --sql="SELECT * FROM ethereum.blocks ORDER BY number DESC LIMIT 5"
Chain IDs
| Chain | ID | Chain | ID |
|---|---|---|---|
| Ethereum | 1 | Optimism | 10 |
| BSC | 56 | Base | 8453 |
| Polygon | 137 | zkSync | 324 |
| Avalanche | 43114 | Merlin | 4200 |
| Arbitrum | 42161 |
Default to Ethereum (chain_id=1) unless user specifies otherwise.
Routing Logic
Match user intent to the right endpoint:
| User wants | Endpoint |
|---|---|
| Top token holders / who holds a token | GET /v1/token/top-holders |
| List of holder addresses | GET /v1/token/holders |
| Token price | GET /v1/token/price |
| Historical token price | GET /v1/token/price/history |
| Token info (name, symbol, supply) | GET /v1/token/metadata |
| Token transfer history | GET /v1/token/transfers |
| Address labels/tags | GET /v1/address/labels |
| Wallet transaction history | GET /v1/account/txs |
| Single transaction detail | GET /v1/tx/detail |
| Native token balance (ETH/BNB) | GET /v1/account/balance |
| ERC20 token balances of wallet | GET /v1/account/tokens |
| NFTs owned by wallet | GET /v1/account/nfts |
| DeFi portfolio positions | GET /v1/account/portfolios |
| ENS domain lookup | GET /v1/ens/records or /v1/ens/reverse |
| NFT metadata/owner/rarity | GET /v1/nft/metadata, /owner, /rarity |
| Trending NFT collections | GET /v1/nft/collection/trending |
| Anything not covered above | SQL API (POST /query/execute) |
Workflow
- Identify intent â Determine what data the user needs
- Resolve identifiers â If user gives token name (e.g. “USDT”), look up the contract address. Common tokens:
- USDT:
0xdAC17F958D2ee523a2206206994597C13D831ec7(ETH) - USDC:
0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48(ETH) - WETH:
0xC02aaA39b223FE8D0A0e5c4F27eAD9083C756Cc2(ETH) - DAI:
0x6B175474E89094C44Da98b954EedeAC495271d0F(ETH) - WBTC:
0x2260FAC5E5542a773Aa44fBCfeDf7C193bc2C599(ETH) - If unknown, use
GET /v1/token/metadataor ask the user for the contract address
- USDT:
- Select endpoint â Use the routing table above; fall back to SQL API for complex/custom queries
- Execute â Run via
scripts/chainbase.shor directcurl - Present results â Format data clearly with tables for lists, highlight key insights
SQL API Fallback
When fixed endpoints don’t cover the query, translate user intent to SQL:
scripts/chainbase.sh /query/execute --sql="SELECT from_address, SUM(value) as total FROM ethereum.token_transfers WHERE contract_address = '0x...' GROUP BY from_address ORDER BY total DESC LIMIT 20"
Common table patterns (replace ethereum with chain name):
{chain}.blocksâ Block data{chain}.transactionsâ Transactions{chain}.token_transfersâ ERC20 transfers{chain}.token_metasâ Token metadata{chain}.logsâ Event logs
SQL constraints: max 100,000 results per query.
