C-Chain API

Contract Chain API documentation

Ethereum has its own notion of networkID and chainID. These have no relationship to Avalanche’s view of networkID and chainID and are purely internal to the C-Chain. On Mainnet, the C-Chain uses 1 and 43114 for these values. On the Fuji Testnet, it uses 1 and 43113 for these values. networkID and chainID can also be obtained using the net_version and eth_chainId methods.

Avalanche offers an API interface identical to Geth's API. Check the full list of supported method calls here.
