# Making calls on Kusama from Your Kreivo Community

## Introduction

Yaay! You just [created your community](https://virto.network/blog/1ksm-1dao-create-community-kreivo/). Now, let's learn how to execute something on Kusama, from your Community.

> Note: This tutorial assumes you're the admin of the community. If you already decentralized your community, and the admin is the community itself, you'll need to encode the final extrinsic and submit a referendum on your community track (this will be covered in the next part of this tutorials).

## 1. Craft the extrinsic to send

1. [Craft the extrinsic][pjs:kusama:extrinsic] you want to execute in the name of the Community.
1. Once you have the extrinsic crafted, copy the encoded call. You'll need it on a couple of places later.
1. Go to the [Runtime][pjs:kusama:runtime] page, and submit the `transactionPaymentCallApi.queryCallInfo` runtime call with the following params:
1. The encoded `call`, and
1. The `len` of the call (you can get it by measuring the encoded call len —without the 0x prefix— and dividing by 2).
1. Save the `refTime` and `proofSize` parameters.

## 2. Prepare the Sovereign Account

> **Note:** Your Community owns two Sovereign Accounts. These accounts represent your Community on Kusama and other Parachains:
>
> We'll soon submit a tool for you to know which are the Sovereign Accounts that represent your Community.

Deposit `0.1 KSM` on the Sovereign Account that represents your Community on Kusama.

This amount will be used for the existential deposit of the account, and is enough to cover the costs XCM execution, the fees of the call, and any other related costs required (like submit deposits for referenda).

## Prepare the XCM Send Call

We've prepared a [base template][pjs:kreivo:template] to send some XCM instructions to Kusama needed to execute a call on the destination chain.

> **Note:** This template is prepared to take a reasonable, conservative amount (`5 µKSM`) from your [Community Sovereign Account](#2-Prepare-the-Sovereign-Account) in Kusama to cover for the base costs of executing the XCM instructions, and the costs of executing the call. Then, deposits the remaining amount back to the account.
>
> Normally, Kusama takes between `1 µKSM` and `3 µKSM`, but some calls might charge a bit more. That's why we reserve `5 µKSM` to cover for fees.

1. Open the [base template][pjs:kreivo:template].
2. Click on the **Submission** button to edit the fields and prepare the extrinsic.
4. There is a couple of XCM instruction in this call you'd need to configure:
1. On the `Transact` instruction, in the `requireWeightAtMost` field, paste the values you saved for `refTime` and `proofSize`.
1. On the `Transact` instruction, in the `call` field, paste the encoded call.
3. On the `DepositAsset` instruction, under the `beneficiary` field, set your community number in the `Plurality` id.
1. Click on **Submit Transaction**.
