## Endpoint shape

For every chain in the table above:

```
https://rpc.goldrushdata.com/v1/{slug}
```

For example, the endpoint for Base mainnet is `https://rpc.goldrushdata.com/v1/base-mainnet`, and for Solana it is `https://rpc.goldrushdata.com/v1/solana-mainnet`.

EVM chains accept the standard `eth_*` / `net_*` / `web3_*` / `debug_*` / `trace_*` methods; Solana accepts the Solana JSON-RPC method set over HTTP and WebSocket subscriptions over `wss://rpc.goldrushdata.com/v1/solana-mainnet`. See the [Solana chain page](/api-reference/json-rpc/chains/solana) for the full method list.

## Listing chains programmatically

To fetch the list of supported chains at runtime, call the `rpc_listChains` method on the `_meta` endpoint:

```bash theme={null}
curl -X POST "https://rpc.goldrushdata.com/v1/_meta" \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","method":"rpc_listChains","id":1}'
```

## Adding a chain

If you need a chain that isn't listed, [contact us](https://goldrush.dev/contact). We add chains based on demand and upstream coverage.
