# TrustSet Link/QR

Offering a direct link / QR code to a payload does **not** come with the advantages of creating a [payloads-sign-requests](https://docs.xaman.dev/concepts/payloads-sign-requests "mention") of getting live feedback & webhooks based on the user's engagement.

The advantage of a simple Sign Link / QR is that you can craft the link / QR once, and it will be available for all users without further code implementations.

Simple Sign Link/QR is available for the following transaction type(s)

* `TrustSet` (adding a Trust Line, a.k.a. adding a Token)

## Crafting the link / QR contents

```javascript
const tx = {
  TransactionType: 'TrustSet',
  Flags: 131072,
  LimitAmount: {
    currency: 'XAH',
    issuer: 'rswh1fvyLqHizBS2awu1vs6QcmwTBd9qiv',
    value: '100000000',
  }
}

const str = JSON.stringify(tx)
const hex = Buffer.from(str, 'utf-8').toString('hex')

console.log(`https://xaman.app/detect/${hex}`)
```
