## Defining Chains/Adding Chains
The default of this repo is to build infra for the `sokol` chain, but you may not want that, or want a different set, so you need to create/edit `terraform.tfvars` or `user.auto.tfvars` and add the following configuration:
The default of this repo is to build infra for the `sokol` chain, but you may not want that, or want a different set, so you need to create/edit `terraform.tfvars` and add the following configuration:
```terraform
chains = {
"mychain" = "url/to/endpoint"
}
chain_trace_endpoints = {
"mychain" = "url/to/debug/endpoint/or/the/main/chain/endpoint"
}
chain_jsonrpc_variant = "parity"
chain = "sokol"
chain_ethereum_url = "https://sokol.poa.network"
chain_trace_endpoint = "https://sokol-trace.poa.network"
chain_ws_endpoint = "wss://sokol-ws.poa.network/ws"
chain_logo = "/images/sokol_logo.svg"
chain_check_origin = "[\"blockscout.com\"]"
chain_coin "POA"
chain_network "POA Network"
chain_subnetwork = "Sokol Testnet"
chain_network_path = "poa"
chain_subnetwork_path = "sokol"
chain_network_icon = "_test_network_icon.html"
```
This will ensure that those chains are used when provisioning the infrastructure.
