Chain IDs
Every blockchain has a Chain ID. It also has a Network ID, but we can ignore that since Chain IDs are unique.
We currently have optimized historical data for the Ethereum, BNB, and Polygon. For other chains, we currently only provide access to an archive node.
This is a list of supported chains:
Chain | Chain ID |
|---|---|
Ethereum | 1 |
BNB | 56 |
Polygon (Matic) | 137 |
Avalanche (C-Chain) | 43114 |
Fantom | 250 |
Arbitrum One | 42161 |
Optimism | 10 |
Support for different blockchains varies by API. Some APIs support only Ethereum, while others support multiple networks. Please refer to the corresponding Reference documentation to confirm which chain IDs are supported.
