# EVM chains (/platform/evm)

> Corvus BSC and Polygon endpoints: standard EVM JSON-RPC and WebSocket, one metro each, included with your rental.



Beside the Solana fleet we run one BSC node and one Polygon node. Both speak standard EVM JSON-RPC, so whatever client you already use works unchanged; point it at the endpoint and go.

| Chain   | Chain ID | Metro     | HTTP JSON-RPC                         | WebSocket                           |
| ------- | -------: | --------- | ------------------------------------- | ----------------------------------- |
| BSC     |       56 | Frankfurt | `http://bsc.fra.corvus-labs.io:8545`  | `ws://bsc.fra.corvus-labs.io:8546`  |
| Polygon |      137 | Amsterdam | `http://poly.ams.corvus-labs.io:8545` | `ws://poly.ams.corvus-labs.io:8546` |

Each chain runs in the one metro listed.

## Get access

Both chains are included with your rental at no extra cost, but the allowlist for them is handled by hand rather than in the dashboard. Ask us on [Discord](https://discord.gg/corvus-labs) with the public egress IP your client calls from, and we'll add it.

That is the same kind of IP allowlist the Solana endpoints use ([Access & authentication](/platform/access)), so register the address traffic actually leaves from rather than the one your host thinks it has.

```bash
curl -s -X POST http://bsc.fra.corvus-labs.io:8545 \
  -H 'content-type: application/json' \
  -d '{"jsonrpc":"2.0","id":1,"method":"eth_blockNumber","params":[]}'
```

## What runs where

These are plain EVM RPC nodes, and JSON-RPC over HTTP and WebSocket is the whole surface. Everything else Corvus sells is Solana only: [Falcon](/falcon), [aRPC](/arpc), [Shredstream](/platform/shredstream) and [Yellowstone gRPC](/solana-rpc/grpc) have no BSC or Polygon equivalent.

If you need EVM capacity in another region, or a dedicated node, ask us on [Discord](https://discord.gg/corvus-labs) rather than assuming an endpoint is there.
