Today, I am gonna show you how to use Waits (TX Delay) to keep your EOS account SAFE.

What is WAITS?

Specifying waits allows a user to ensure that transaction may not be executed without a required delay.

Look at my testing account first:
alt
There is no wait on account4test. I will add waits to active permission.

Let's start!

I. Add Waits

Login your EOS account with your Active Key on bloks.io => Wallet => Permissions Manager

Change the info:
alt

Threshold (always >=2): 2
Keys:
- change the threshold of EOS8gKJKboCpK1XtoM3EajUDLZ6rVubBjN5TifMw6q1sHav3smCrS to 2 (I change it just for backup or make any transaction immediately when needed. You can keep 1)
- Add a new key EOS63MkrMsTUrKwK5LshQnahRCpQPtaq4deLXNQca446Y4GFAQ5r6 with threshold 1
Waits (always < threshold): 1

Click Save Permission

When completed, check out your account permissions

II. Let's test!

In this guide, I am gonna transfer tokens
1)Using Keys (Singlesig Mode)

Login with the new key EOS63MkrMsTUrKwK5LshQnahRCpQPtaq4deLXNQca446Y4GFAQ5r6
To satisfy the new permission: I will schedule the transaction to be delayed by 3 minutes and provide authorization for the key EOS63MkrMsTUrKwK5LshQnahRCpQPtaq4deLXNQca446Y4GFAQ5r6
- Change TX Delay (s) to 180 seconds (3 minutes)
Go to Wallet => Transfer Tokens
Click on Transfer 0.1 EOS to iloveueosdac
Then click on TX 0e6cb9034de72a45004666944aaa233bed9a8734c6bb3a7a98d9a0baa7ffd425
You will see

Transaction Not Found: the transaction is only going online after 3 minutes. However, that consumed some RAM (that shows the transaction is about to go online)
3 minutes later, you refresh the page and see the transaction online

The transaction is done!

2)Using Accounts (Multisig Mode)

I change my account active permissions

_{How to make a multisig tx: https://steemit.com/eos/@eosdacvietnam/eos-guide-keep-your-eos-account-safe-using-multisig-structure}
Requirements:
- Number of accounts >= 2
- When prososing a Multisig Transaction, before click Propose, click Show on first, you will see

alt
Focus on delay_sec, change 0 to 180 (180 seconds = 3 minutes) to satisfy the threshold 3 minutes. That is why in Requested Approvals, you just put on 2 accounts. Then, approve and execute the TX.

NOTE:

If you use the key with the highest threshold, Waits (TX Delay) is Optional. You can put any TX Delay. No need to be like the Waits on your EOS account.
If you use the key with lower threshold, Waits (TX Delay) is required and must be the same as the Waits on your EOS account.
