Step 8: Deposit ETH and SD

ETH Deposit​

Run the below mentioned command to deposit ETH bond and add validators to your node: ~/bin/stader-cli validator deposit --num-validators <number of validators you wish to add>

Please ensure to replace the placeholder <number of validators you wish to add> with the number of validators you want to add to your node by depositing the ETH bond.

SD Deposit​

The SD token plays a vital role in the Stader platform, serving as the governance token. It allows the Stader community to actively participate in shaping the platform's direction. Therefore, to add a validator to the nodes on the Stader Network, permissionless node operators are required to bond SD collateral for each validator. In return, the node operators receive SD rewards for their bonded SD collateral.

The minimum deposit requirement is 0.4ETH worth of SD per validator, while the maximum allowed deposit is 8ETH worth of SD per validator. The exact value will vary dynamically based on the current price of ETH and SD.

If you have deposited SD earlier and there is enough SD bond in the SD collateral contract to create the number of validators you have specified, then your validator will be created directly. If you have not deposited SD earlier then the CLI will give you two choices for SD collateral deposit

• Utilize SD from the SD Utility Pool

• Use your own SD (Self Bond)

Note

• SD collateral snapshots are taken daily at a random block. Therefore, if the SD collateral value falls below the 10% limit, the node operator will not earn SD rewards for that day.

• We recommend maintaining an SD collateral buffer (above the 0.4 ETH worth of SD per validator limit) to avoid any reward loss due to price fluctuations.

• You can deposit more than 8ETH worth of SD per validator as collateral, but any SD collateral exceeding the 8ETH limit will not earn SD rewards.

• For SD collateral withdrawal, the node operators can withdraw any collateral exceeding the 200% SD collateral limit (8 ETH worth of SD per validator). To withdraw the entire SD collateral, the node operator will need to exit the validators.

• Before depositing SD collateral, you will first need to give approval to the collateral contract to access your SD token. This approval step will only be done once.

Set spend approval limit for SD deposit

SD Spend approval Limit allows users to set the allowance value in the ETHx Smart Contract for SD token spending, ensuring your control over your assets. It enables users to define a maximum amount of tokens that can be deposited without requiring re-authorization. If you don't set the SD approval limit, you will have to provide approval every time you deposit SD tokens. To set the SD approval limit, please execute the following command: ~/bin/stader-cli node approve-sd --amount <SD Amount>

Note: Please ensure to replace <SD Amount> with the desired amount of SD for spending approval.
