Buy space

If you want to upload files to the CESS network, you first need to purchase a certain amount of storage space.

The method to purchase space is BuySpace, the unit is GB.

The space purchased for the first time is valid for 30 days.

Refer to the following code:

package main

import (
	"context"
	"fmt"

	cess "github.com/CESSProject/cess-go-sdk"
)

// Substrate well-known mnemonic:
//
//	https://github.com/substrate-developer-hub/substrate-developer-hub.github.io/issues/613
var MY_MNEMONIC = "bottom drive obey lake curtain smoke basket hold race lonely fit walk"

var RPC_ADDRS = []string{
	"wss://testnet-rpc0.cess.cloud/ws/",
	"wss://testnet-rpc1.cess.cloud/ws/",
	"wss://testnet-rpc2.cess.cloud/ws/",
}

func main() {
	sdk, err := cess.New(
		context.Background(),
		cess.ConnectRpcAddrs(RPC_ADDRS),
		cess.Mnemonic(MY_MNEMONIC),
	)
	if err != nil {
		panic(err)
	}
	// buy 1GiB space
	fmt.Println(sdk.BuySpace(1))
}
