Unstaking

Intro

When unstaking, you withdraw your coins from the staking balance of the validator you previously staked on.

Method 1 - via user interface

Again, the easiest way to do this is through the interface on our website. As you remember:

1. We staked 27 coins

2. On the pool 6XvZpuCDjdvSuot3eLr24C1wqzcf2w4QqeDh9BnDKsNE

3. From our account 0x9f8E68B1974069B854eE481deC0819697B901f1D

Our account is still on the list of stakers and receives rewards:

On site - choose the mode Unstake . Input the amount and your pool

Confirm the transaction

Check the transaction status via explorer

Unstaking also require some time. So, now we know that unstaking transaction was in block in epoch 12:

So, let's wait for epoch 12 + 3 = 15

After this - you should receive your stake back

And if you visit the page of pool info:

You will see that your account is not in the stakers list

As you can see, your account has been removed from the list of stakers in this pool. From this moment on, you will no longer receive rewards.

Method 2 - programmatic way using SDK

Let's assume that we have this:

1. Your address - 3JAeBnsMedzxjCMNWQYcAXtwGVE9A5DBQyXgWBujtL9R

2. Pool you staked on - 9GQ46rqY238rk2neSwgidap9ww5zbAN4dyqyC7j5ZnBK

Let's assume that we want to do the following:

1. Unstake 30 coins - this will return to our balance

2. 70 coins remain in the pool - you will continue to receive rewards from the validator

1. Call system smart contract to unstake

import Web1337 from 'web1337';


let web1337 = new Web1337({

    chainID:'aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa',
    workflowVersion:0,
    nodeURL: 'http://localhost:7332'

});


let keypair = {

    pub:"3JAeBnsMedzxjCMNWQYcAXtwGVE9A5DBQyXgWBujtL9R",

    prv:"MC4CAQAwBQYDK2VwBCIEIDteWfNev7NOlNmwP8Irwg5miWKoErYGV+UU5VrFgYev"

};

const shardID = "shard_0";


let payload = {

    shard: shardID,

    contractID:'system/staking',

    method:'unstake',

    gasLimit:0,

    params:{

        poolPubKey:'9GQ46rqY238rk2neSwgidap9ww5zbAN4dyqyC7j5ZnBK',
        amount: '30000000000000000000'

    },

    imports:[]

}


const fee = 2;

const nonce = await web1337.getAccount(shardID,keypair.pub).then(account=>account.nonce+1);

const txType = "WVM_CALL";

let tx = web1337.createEd25519Transaction(shardID,txType,keypair.pub,keypair.prv,nonce,fee,payload);

console.log(tx);

web1337.sendTransaction(tx).then(value =>{

    console.log('Sent => ',value)

    console.log(`TX ID is => `,web1337.blake3(tx.sig))

}).catch(err=>console.error('Error with unstaking: ',err));

Output:

{
  v: 0,
  creator: '3JAeBnsMedzxjCMNWQYcAXtwGVE9A5DBQyXgWBujtL9R',
  type: 'WVM_CALL',
  nonce: 2,
  fee: '2000000000000000000',
  payload: {
    shard: 'shard_0',
    contractID: 'system/staking',
    method: 'unstake',
    gasLimit: 0,
    params: {
      poolPubKey: '9GQ46rqY238rk2neSwgidap9ww5zbAN4dyqyC7j5ZnBK',
      amount: '30000000000000000000'
    },
    imports: []
  },
  sigType: 'D',
  sig: 'YkfiMMLFopmxwuf3pmuKgNrpcdOuhxg3D+szrMQyIwk6DcUCS0Tl4taNIbGX1nGsQRMXiuNpKASxqyUCJxZ0Cg=='
}
Sent =>  { status: 'OK' }
TX ID is =>  ee8053b379a44662252afcd42a316e152f47a45353f7accd294a9ee321a38aed

2. Check the unstaking tx status

Go to explorer and try to find your transaction

Transaction finished with Success 🟢 status

3. Wait untill the next epoches

There is also a delay for the unstaking procedure. Since the transaction was in epoch 61

Then you will receive the coins in epoch 61+3=64

4. Check that you have less coins in pool and receive your coins back

We waited for a while and now the epoch is 64. Let's try to go to the pool page and see the list of stakers now:

Now in pool you have 70 coins instead of 100

And if you visit the page of your account you will see that 30 coins was sent to your address back

Calculation:

Init balance: 20_000_000 (20 millions)

Balance after staking: 20_000_000 - 100(staking) - 2(fee) = 19_999_898

Balance after unstaking: 19_999_898 + 30(unstaking) - 2(fee) = 19_999_926

As you can see, everything is correct ✅
