Deploying a Smart Contract

For a tutorial on deploying a Solidity smart contract on the C-Chain, see here.


This API is identical to Geth’s API except that it only supports the following services:
  • web3_
  • net_
  • eth_
  • personal_
  • txpool_
You can interact with these services the same exact way you’d interact with Geth. See the Ethereum Wiki’s JSON-RPC Documentation and Geth’s JSON-RPC Documentation for a full description of this API.

JSON-RPC Endpoints

To interact with C-Chain (the main EVM instance on Avalanche):
To interact with other instances of the EVM:
