# Mint/Redeem vToken without Dapp

## Summary

This tutorial will guide you through vToken minting and redemption without using the Bifrost Dapp, or in case the Bifrost Dapp is temporarily unavailable.

## Where to do？

By using <mark style="color:purple;">Polkadot.JS</mark>, you can directly interact with Bifrost parachain, calling specific functions such vToken minting or redemption. Choose the environment below, depends on where your assets at:

#### <mark style="color:purple;">Bifrost-Polkadot</mark> (vDOT, vGLMR, vFIL, vASTR, vBNC)

{% embed url="<https://polkadot.js.org/apps/?rpc=wss://eu.bifrost-polkadot-rpc.liebi.com/ws#/extrinsics>" %}

#### <mark style="color:purple;">Bifrost-Kusama</mark> (vKSM, vMOVR)

## Token and vToken Index Library

### Token Indexes on <mark style="color:purple;">**Bifrost-Polkadot**</mark>

**NOTE**: Decimal means how many "0" follows 1 Token. E.g, DOT or vDOT decimal is 10, so 1 DOT = 10,000,000,000 which by followed up with ten "0".

| Token  | Token ID, U8 | Decimals | Redeem Period (day) |
| ------ | ------------ | -------- | ------------------- |
| DOT    | Token2, 0    | 10       | -                   |
| vDOT   | vToken2, 0   | 10       | 0-28                |
| GLMR   | Token2, 1    | 18       | -                   |
| vGLMR  | vToken2, 1   | 18       | 0-7                 |
| ASTR   | Token2, 3    | 18       | -                   |
| vASTR  | vToken2, 3   | 18       | 0-10                |
| FIL    | Token2, 4    | 18       | -                   |
| vFIL   | vToken2, 4   | 18       | 0-520               |
| MANTA  | Token2, 8    | 18       | -                   |
| vMANTA | vToken2, 8   | 18       | -                   |
| BNC    | Native, BNC  | 12       | -                   |
| vBNC   | vToken, BNC  | 12       | 0-7                 |

### Token Indexes on <mark style="color:purple;">**Bifrost-Kusama**</mark>

**NOTE**: Decimal means how many "0" follows 1 Token. E.g, KSM or vKSM decimal is 12, so 1 KSM = 1,000,000,000,000 which by followed up with twelve "0".

| Token | Token ID, U8 | Decimals | Redeem Period (day) |
| ----- | ------------ | -------- | ------------------- |
| KSM   | Token, KSM   | 12       | -                   |
| vKSM  | vToken, KSM  | 12       | 0-7                 |
| MOVR  | Token, MOVR  | 18       | -                   |
| vMOVR | vToken, MOVR | 18       | 0-2                 |

## Quick Calls

Quick calls can help you quickly construct the transactions, but overview the details of each step in tutorials is strongly suggested.

{% hint style="info" %}
All the quick calls below had constructed with right decimals with 1 Token as cases, so you can just replace the 1st number to how many acutal tokens that you want to mint or redeem , so it works.
{% endhint %}

For example, if the value is 10,000,000,000 in the case below, and you want to mint or redeem 15 tokens, simply replace 1 with 15 so that it becomes 150,000,000,000 with the correct decimals.

| Token  | Mint                                                                                                                                                               | Redeem                                                                                                                                                         |

## How to mint vToken?

1. Please make sure you select the right **chain of Polkadot JS** before you follow up with the following process, it depends on what vToken you want to mint, check above section at [Where to do](#where-to-do)?.
2. Selet Extrinsics

3. Select which address that you want to mint vToken, and construct `vtokenminting`, `mint` as below. (make sure you have BNC in balance to pay for transaction fee)

<figure><img src="https://757947912-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FJFtVsA5N3spWTWKvFvv0%2Fuploads%2FCUl3Eu34s0kh9w4yOuxX%2Fimage.png?alt=media&#x26;token=5ae1efa3-59fc-469b-b0fb-ed8ad3ebbfd5" alt=""><figcaption></figcaption></figure>

4. Fill up what token that you want to mint for, we take an example as using 1 DOT for vDOT minting here. (Check [Token Index Chart](#token-and-vtoken-index-library) to find what to put here.)
   1. Since DOT index is Token2, 0, so we put Token2 in `tokenid`, and put 0 in `token2:u8`.
   2. Since DOT decimal is 10, so we put 10,000,000,000 in `tokenAmount`
   3. You can put anything in `remark`.
   4. Submit and sign transaction. (make sure you have [wallet extension](https://docs.bifrost.io/faq/what-are-vtokens/broken-reference) installed)
   5. Wait for transction processing and check the right corner, green means succeed, red means failed.

5. Check your balance by select Chain State

6. Select `tokens`, `accounts,`and input what token balance that you are checking for. In the above case, we used DOT to mint vDOT, so we want to check my vDOT balance here.

## How to redeem vToken?

1. Please make sure you select the right **chain of Polkadot JS** before you follow up with the following process, it depends on what vToken you want to mint, check above section at [Where to do](#where-to-do)?.
2. Selet Extrinsics

<figure><img src="https://757947912-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FJFtVsA5N3spWTWKvFvv0%2Fuploads%2FVGmHghDPdO8nZqFBkFvZ%2Fimage.png?alt=media&#x26;token=95b8e825-9376-4597-bdc1-3dc560cec24a" alt=""><figcaption></figcaption></figure>

3. Select which address that you want to redeem vToken, and construct `vtokenminting`, `redeem`as below. (make sure you have BNC in balance to pay for transaction fee)

<figure><img src="https://757947912-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FJFtVsA5N3spWTWKvFvv0%2Fuploads%2FleYiJY7xHwCS4OYUWb2O%2Fimage.png?alt=media&#x26;token=7caecef0-e591-4f44-a2a1-0729310d5ccd" alt=""><figcaption></figcaption></figure>

4. Fill up what token that you want to redeem for, we take an example as using 0.4 vDOT redeeming DOT here. (Check [Token Index Chart](#token-and-vtoken-index-library) to find what to put here.)\
   **NOTE**: The minimum redeem for vDOT is 0.4 vDOT
   1. Since vDOT index is vToken2, 0, so we put vToken2 in`tokenid`, and put 0 in `vtoken2:u8`.
   2. Since vDOT decimal is 10, so we put 4,000,000,000 in `tokenAmount`
   3. Submit and sign transaction. (make sure you have [wallet extension](https://docs.bifrost.io/faq/what-are-vtokens/broken-reference) installed)
   4. Wait for transction processing and check the right corner, green means succeed, red means failed.

<figure><img src="https://757947912-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FJFtVsA5N3spWTWKvFvv0%2Fuploads%2FU4150rja6dojphUVn87j%2Fimage.png?alt=media&#x26;token=d0996c6f-0366-43ba-9565-7e254776af95" alt=""><figcaption></figcaption></figure>

5. Wait for redemption period and receive Token back. Check corresponding redemption period of each vToken [above](#token-and-vtoken-index-library).
