This is a sample golang client for the Solana gRPC interface.

Requires golang 1.17
Requires golang 1.21

Sample usage:

```
go1.17 run ./cmd/grpc-client/ -endpoint https://api.rpcpool.com:443 -x-token <token> -slots
go run ./cmd/grpc-client/ -endpoint https://api.rpcpool.com:443 -x-token <token> -slots
```

You can also make non SSL connections:

```
go1.17 run ./cmd/grpc-client/ -endpoint http://api.rpcpool.com:80 -x-token <token> -blocks
````
go run ./cmd/grpc-client/ -endpoint http://api.rpcpool.com:80 -x-token <token> -blocks
```

## Updating protofiles

Make sure you have protoc installed for go:
Make sure you have protoc installed:

```bash
$ protoc --version
libprotoc 28.3
```

And the golang plugins:

```bash
$ go list -f '{{.Path}} {{.Version}}' -m google.golang.org/protobuf
google.golang.org/protobuf v1.35.1
$ go list -f '{{.Path}} {{.Version}}' -m google.golang.org/grpc
google.golang.org/grpc v1.67.1
```

If you don't have the protobuf go plugins installed, you can install them with:

```
$ go install google.golang.org/protobuf/cmd/protoc-gen-go@v1.28
$ go install google.golang.org/grpc/cmd/protoc-gen-go-grpc@v1.2
$ go install google.golang.org/protobuf/cmd/protoc-gen-go@v1.35.1
$ go install google.golang.org/grpc/cmd/protoc-gen-go-grpc@v1.5.1
