Would you like to create a reward share transaction, sharing <strong>${this._percentageShare / 1e8}%</strong> of your minting rewards with <strong>${this.constructor.Base58.encode(this._recipient)}</strong>?
|
|
If yes, you will need to save the key below in order to mint. It can be supplied to any node in order to allow it to mint on your behalf.
|
|
<div style="background: #eee; padding: 8px; margin: 8px 0; border-radius: 5px;">
|
|
<span style="color: #000;">${this._base58RewardShareSeed}</span>
|
|
</div>
|
|
On pressing confirm, the rewardshare will be created, but you will still need to supply the above key to a node in order to mint with the account.
