Staking with Polkadot JS
This document describes how you can stake to Opentensor Foundation using Polkadot JS.
Also see Delegation.
In addition to running your own subnet miner or subnet validator, you can delegate your TAO to the Opentensor Foundation validation pool. Delegating TAO simply means you are staking to the Opentensor Foundation's validator, instead of running your own subnet validator. To take back your staked TAO from the pool at any time, you can simply undelegate your TAO.
Consider your endpoint security before following the procedure documented below!
The following procedure involves adding a coldkey wallet seed phrase into a digital device (a computer capable of running the Polkdadot Extension for Chrome).
Anyone who obtains your seed phrase in any way owns your TAO.
Any time you enter a seed phrase onto a digital device, the wallet is permanently rendered no more secure than the device—anyone who obtains it in the future can attempt to scan it for any seed phrases that have ever been input into it.
Consider Using a Ledger Hardware Wallet to manage your Bittensor coldkey and sign transactions.
Follow the below steps:
-
Add your Bittensor wallet to the Polkadot Extension wallet in your browser (you will need your mnemonic to do this). After you have done so, navigate to Polkadot JS and your account will be displayed there.
-
Navigate to Developer > Extrinsics.
-
In the drop-down, select subtensorModule.
-
In the drop-down menu for the subtensorModule, select addStake.
-
Paste the hotkey of the delegate in the box labeled hotkey.
-
In the box labeled amountStaked, input, in units of Rao, the amount of TAO that you wish to stake to this delegate.
Note that 1 TAO = 109 Rao. Therefore, if you wish to stake 1 TAO, then input 1000000000 (
1followed by nine zeros). If you wish to stake 10 TAO, then input 10000000000 (1followed by ten zeros), and so on.
-
After you have verified the keys and amounts, click Submit Transaction to sign and submit this transaction to be included on the chain.
