# Overview

We primarily support the following EVM based networks for JSON-RPC calls. These
networks will have the best performance in our system.

| Name | Chain Id | URL |
| - | - | - |
| Ethereum mainnet | 1 | [https://api.bitski.com/v1/web3/1](https://api.bitski.com/v1/web3/1) |
| Ethereum Goerli | 5 | [https://api.bitski.com/v1/web3/5](https://api.bitski.com/v1/web3/5) |
| Polygon mainnet | 137 | [https://api.bitski.com/v1/web3/137](https://api.bitski.com/v1/web3/137) |
| Base | 8453 | [https://api.bitski.com/v1/web3/8453](https://api.bitski.com/v1/web3/8453) |
| Polygon Mumbai | 80001 | [https://api.bitski.com/v1/web3/80001](https://api.bitski.com/v1/web3/80001) |
| Optimism | 10 | [https://api.bitski.com/v1/web3/10](https://api.bitski.com/v1/web3/10) |
| Arbitrum One | 42161 | [https://api.bitski.com/v1/web3/42161](https://api.bitski.com/v1/web3/42161) |

Additionally, any EVM chain on [https://chainlist.org/](https://chainlist.org/) should work but will be
using publicly hosted RPC nodes. Simply replace the chain id in the RPC url:
`https://api.bitski.com/v1/web3/chains/{chain_id}`.

### Unsupported Networks

Rinkeby and Kovan Ethereum testnets are no longer supported and RPC calls will
fail.
