# 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.
