Unstaking

Intro

TODO

Method 1 - via user interface

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: 30

    },

    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:

  creator: '3JAeBnsMedzxjCMNWQYcAXtwGVE9A5DBQyXgWBujtL9R',
  type: 'WVM_CALL',

  payload: {
    shard: 'shard_0',
    contractID: 'system/staking',
    method: 'unstake',
    gasLimit: 0,

      poolPubKey: '9GQ46rqY238rk2neSwgidap9ww5zbAN4dyqyC7j5ZnBK',
      amount: 30
    },

}
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 63

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

We waited for some time and now the epoch is 64 (even more than 63).

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 ✅
