Staking Pool Operations

This document describes how to perform staking pool operations. Note that a staking pool can only accept stake from the stake pool owner. You can stake only when you meet the minimum staking requirement.

Minimum staking requirement

The current minimum staking requirement is 1 million APT.

See also the related Delegation Pool Operations instructions to accept stake from multiple delegators in order to reach the minimum staking requirement.

Pool types are static

There is no upgrade mechanism for the staking contract to move from a staking pool to a delegation pool. A new delegation pool must be created.

Initialize a staking pool

Testnet vs Mainnet

The Aptos CLI commands below target mainnet. Change the --network value for testnet and devnet. View the values in Aptos Blockchain Networks to see how profiles can be configured based on the network.

Before initializing a staking pool, ensure that there is an existing owner account with 1 Million APT.

  1. Initialize the Aptos CLI with a private key from an existing account, such as a wallet, or create a new account.
aptos init --profile mainnet-owner \
--network mainnet

You can either enter the private key from an existing wallet, or create new wallet address.

  1. Run the following command to initialize the staking pool:
aptos stake create-staking-contract \
--operator <operator-address> \
--voter <voter-address> \
--amount 100000000000000 \
--commission-percentage 10 \
--profile mainnet-owner
  1. Once the staking pool has been initialized, you can proceed to connect to the Aptos Network.

Perform pool owner operations

Transfer coin between accounts

aptos account transfer \
--account <operator-address> \
--amount <amount> \
--profile mainnet-owner

Switch operator

aptos stake set-operator \
--operator-address <new-operator-address> \
--profile mainnet-owner

Switch voter

aptos stake set-delegated-voter \
--voter-address <new-voter-address> \
--profile mainnet-owner

Add stake

aptos stake add-stake \
--amount <amount> \
--profile mainnet-owner

Increase stake lockup

aptos stake increase-lockup --profile mainnet-owner

Unlock stake

aptos stake unlock-stake \
--amount <amount> \
--profile mainnet-owner

Withdraw stake

aptos stake withdraw-stake \
--amount <amount> \
--profile mainnet-owner

Update commission

aptos move run --function-id 0x1::staking_contract::update_commision \
--args address:<operator_address> u64:<commission_percentage> \
--profile mainnet-owner

Set beneficiary addresses for operators

Staking pool operators can set beneficiary addresses to receive the operator commission earned by the staking pool.

  • The beneficiary addresses can be set by the operator using the following command:

    aptos move run --profile mainnet_operator \
    --function-id 0x1::staking_contract::set_beneficiary_for_operator \
    --args address:<new_beneficiary_address>
  • To view the beneficiary address set for the operator, use the following command:

    aptos move view --url <REST API for the network> \
    --function-id 0x1::staking_contract::beneficiary_for_operator \
    --args address:<operator_address>

Any existing unpaid commission rewards will be paid to the new beneficiary. To ensures payment to the current beneficiary, one should first call distribute before switching the beneficiary. In case an operator operates multiple staking pools, the operator can set one beneficiary for all the staking pools, not a separate one for each pool.

Once the beneficiary address is set, the beneficiary can claim the operator commission by request_commission.

Checking your stake pool information

How validation works

Before you proceed, see Validation on the Aptos blockchain for a brief overview.

To check the details of your stake pool, run the below CLI command with the get-stake-pool option by providing the --owner-address and --url fields.

The below command is for an example owner address e7be097a90c18f6bdd53efe0e74bf34393cac2f0ae941523ea196a47b6859edb.


For testnet or devnet --url field values, see Aptos Blockchain Networks.

aptos node get-stake-pool \
--owner-address e7be097a90c18f6bdd53efe0e74bf34393cac2f0ae941523ea196a47b6859edb \
--profile mainnet-operator

Description of output fields


  • "Active": Validator is already in the validator set and proposing.
  • "Pending_active": Validator will be added to the validator set in the next epoch. **Do not try to join the validator set again before the arrival of next epoch, or else you will receive an error. **


  • Use this "pool_address" (not the operator address) in you validator.yaml file. If you mistakenly used the operator address, you will receive the message: "Validator not in validator set".


  • This can be set only by the stake pool owner. Operator receives the "commission_percentage" of the generated staking rewards. If you request the commission (you can do so by running the command aptos stake request-commission), then at the end of the lockup_expiration_utc_time the commission part of the rewards will go to the operator address while the rest will stay in the stake pool and belong to the owner. Here "the commission part of the rewards" means the value of commission_not_yet_unlocked.

    For example, in a scenario with a lock-up of one month, you call aptos stake request-commission every month. This will pay out the commission that was accrued during the previous month but only when unlocked at the end of the previous month. Regardless of how often you run aptos stake request-commission during the month, the commission is only paid out upon the completion of lockup_expiration_utc_time.


    Note that if you do not request commission for multiple months, your commission will accrue more due to compounding of the commission_percentage during these months.


  • The amount of commission (amount of APT) that is not yet unlocked. It will be unlocked at the lockup_expiration_utc_time. This is the total commission amount available to the operator, i.e., the staking rewards only to the operator. This does not include the staking rewards to the owner.


  • The date when the commission will unlock. However, this unlocked commission will not be auto-disbursed. It will only disburse when the command aptos stake request-commission is called again.


  • Use the Epoch Converter to convert the unix_time into human-readable time.

Requesting commission

Either an owner, an operator or the beneficiary of the operator can request commission. You must request commission twice, once before the end of the lockup period and a second time after the lockup period ends, i.e., at the end of lockup_expiration_utc_time, by running the aptos stake request-commission command. Make sure to provide the operator and the owner addresses. See an example command below:

aptos stake request-commission \
--operator-address 0x3bec5a529b023449dfc86e9a6b5b51bf75cec4a62bf21c15bbbef08a75f7038f \
--owner-address 0xe7be097a90c18f6bdd53efe0e74bf34393cac2f0ae941523ea196a47b6859edb \
--profile mainnet-operator

When you run the aptos stake request-commission command before the end of the lockup expiration, the command will initiate unlock for any locked commission earned up until that moment in time. The commission will remain in pending_inactive until the end of the lockup period, will continue to earn rewards until the lockup period expires. The commission will not be withdrawable until after the end of the lockup period, when aptos stake request-commission is called a second time.

See example below:

Month 1 Day 29, you call the command, it would initiate unlock for 29 days worth of commission.

Month 2, Day 29, if you call the command again, it would disburse the fully unlocked commission from previous month (29 days worth), and initiate commission unlock for Month 1 Day 30 + Month 2 Day 1-29 (30 days worth).

Month 3, Day 29, if you call the commission again, 30 days of commission would be disbursed, and a new batch of commission would initiate unlock.

You can call the command multiple times, and the amount you receive depends on the day when you requested commission unlock previously.

Commission is unlocked when request-commission is called, the staker unlocks stake, or the staker switches operator.

Checking your validator performance

To see your validator performance in the current and past epochs and the rewards earned, run the below command. The output will show the validator's performance in block proposals, and in governance voting and governance proposals. Default values are used in the below command. Type aptos node get-performance --help to see default values used.

aptos node get-performance \
--pool-address <pool address> \
--profile mainnet-operator

Example output:

"Result": {
"current_epoch_successful_proposals": 56,
"current_epoch_failed_proposals": 0,
"previous_epoch_rewards": [
"epoch_info": {
"epoch": 68,
"epoch_interval": 3600000000,
"last_epoch_start_time": {

Description of fields


  • Successful leader-validator proposals during the current epoch. Also see Validation on the Aptos blockchain for the distinction between leader-validator and the voter-validator.


  • An ordered list of rewards earned (APT amounts) for the previous 10 epochs, starting with the 10 epoch in the past. In the above example, a reward of 12312716242 APT was earned 10 epochs past and a reward of 12313600288 APT was earned in the most recent epoch. If a reward is 0 for any epoch, then:
    • Either the validator was not part of the validator set in that epoch (could have been in either inactive or pending_active validator state), or
    • The validator missed all the leader proposals.

Checking the performance for all epochs

To check the performance of all the epochs since the genesis, run the below command. You can filter the results for your pool address with grep, as shown below:

aptos node analyze-validator-performance \
--analyze-mode detailed-epoch-table \
--profile mainnet-operator \
--start-epoch 0 | grep <pool address>

Tracking rewards

DistributeEvent is emitted when there is a transfer from staking_contract to the operator or staker (owner). Rewards can be tracked either by listening to DistributeEvent or by using the View function to call staking_contract_amounts. This will return accumulated_rewards and commission_amount.
