How to add endpoint

To add endpoints managed by chainlist, You must add an endpoint to https://github.com/cosmostation/chainlist/blob/main/chain/{chain}/param.json

{
   ...,
    "grpc_endpoint" : [
        {
            "provider": "Cosmostation",
            "url": "grpc-humans.cosmostation.io:443"
        },
        {
            "provider": "NodeStake",
            "url": "grpc.humans.nodestake.top:443"
        }
    ],
    "evm_rpc_endpoint" : [
        {
            "provider": "Cosmostation",
            "url": "https://rpc-humans-evm.cosmostation.io"
        },
        {
            "provider": "Posthuman",
            "url": "https://evm.humans.posthuman.digital"
        }
    ],
   ...
}

Before requesting addition, please check whether the endpoint is operating properly using the method below.

• Check gRPC Endpoint

GRPC_URL=<GPRC_ENDPOINT_URL>

#check has grpc endpoints
grpcurl $GRPC_URL list
#check has grpc nodeinfo
grpcurl $GRPC_URL cosmos.base.tendermint.v1beta1.Service.GetNodeInfo

• Check EVM Endpoint

EVM_URL=<EVM_ENDPOINT_URL>

curl --location '$EVM_URL' \
--header 'Content-Type: application/json' \
--data '{
    "jsonrpc": "2.0",
    "method": "eth_getBlockByNumber",
    "params": [
        "latest",
        false
    ],
    "id": 1
}'
