How to Send Crypto with a S1 Hardware Wallet

This guide provides a step-by-step tutorial on how to send crypto using an S1 hardware wallet. 

Notes: 

1. Blockchain transfers are irreversible. Please carefully check your transaction details (amount, address, etc) to avoid a mistaken transfer. 
2. Do NOT send crypto across the blockchains, or it will lead to permanent asset loss. For example, you shouldn't transfer USDT (TRC20) to a USDT (ERC20) address. 
3. If you are going to transfer a big amount of coins/tokens, it is always better to send a small amount first in case anything goes wrong. 

Before the reading, please make sure that you have set up the S1 hardware wallet properly and added the coins you like or own to the wallet (view the guide).

Following is a youtube tutorial of sending crypto using an S1 hardware wallet, in case you prefer a video guide.

Step 1   On the SafePal App, choose the token/coin you want to send, and click 'Send'.

In this article, we will use BNB (BEP20) as an example.  

Step 2   Enter the destination address and amount and click 'Next' to confirm the details again. 

Notes:

1. If you are sending the funds to a centralized exchange, don't forget to add Memo or Tag in the 'MEMO' space. Centralized exchanges need the Memo/Tag to identify the owner of a specific incoming transfer. 
2. Since blockchain transfers are irreversible, always double-check the transfer details to avoid potential fund loss.

Step 3  Initiate the signing process of the S1 device

Once you have confirmed the transfer details, click 'Send' on the App.

There will be a QRcode containing the transfer details displayed on the SafePal App. Start your S1 hardware wallet, and enter the 'Scan' tab. Then use the S1 hardware wallet to scan the QR code on the SafePal App.

By doing this, the S1 device can receive the transfer details in an offline and air-gapped environment. 

Step 4 Sign the transfer on S1

Now you can see the transfer details on the S1 device. Check the details again, and enter the PIN code.

Step 5   Synchronize the signature back to the SafePal App

By signing the transfer on the S1 device, you will see a set of dynamic QR codes shown on the S1 device. On the SafePal App, click 'Next' to open the cellphone camera. 

Use the SafePal App to scan the dynamic QR codes shown on the S1 device. 

By doing this, the App will receive the signature contained in the QR codes and be ready to broadcast the transfer to the blockchain. 

Step 6  Click 'Broadcast' on the App and wait for the transfer to go through

Once the App receives the signature from the S1 device, there will be a pop-up message asking if you would like to broadcast the transfer. Click 'Broadcast', and the transfer is now broadcast on the blockchain!

Don't forget to check in your App and see if the transfer goes through successfully.
