Aptos (APT) staking guide on Coinbase Prime

Ability to stake when using the following entity:

• Coinbase Custody Trust Company, LLC: Yes

• Coinbase Luxembourg S.A.: Yes

• Coinbase Germany GmBH: Yes

• Coinbase Inc.: Yes

• Validator Active set minimum requirement (Validator Min.): 1M APT

• Public validator staking minimum required by Coinbase Prime: 11 APT

• Staking maximum: There is no maximum stake amount per wallet. A validator can only earn rewards for up to 50M APT staked to it.  

• Estimated rewards rate: Rewards rates vary - visit the Coinbase Developer Platform staking details for current estimated reward rates

• Estimated reward payout: Every epoch (~2 hours)

• Delegator reward compound: Automatic

Accrued rewards do not generate on-chain transactions shown in the Prime account Activity page. Instead, they are auto-compounded and can be claimed by unstaking the full wallet. They are subject to the same staking lockup periods as the initial staked balance.  

Once the rewards are unstaked, the pending rewards materialize on-chain and are credited to the Vault wallet less the validator fees. 

Lockups are not static periods but instead staked APT is locked up for fixed durations and automatically renewed when they expire. The current period is 14 days.

• Warm up period:  The validator becomes active and starts to earn rewards once the minimum is met and the next 14 day lockup period begins. 

• Bonding/Unbonding period: 

1. Staking runs on 14 day lockup periods from when the period starts. The 14 day lockup automatically renews at the end of each cycle unless an unstake or the validator resets the lock up.

2. Unstaking does not have a static unbonding period. Instead, assets unbond and become withdrawable at the end of the current lock up period.

Staking Functionality:

• Ability to unstake assets: Yes

• Ability to partially unstake wallet: Yes

• Ability to partially stake a wallet: No

• Ability to change validator without unbonding and restaking: No

You can remove partial amounts of your staked balances from earning rewards on Coinbase Prime. See the asset specific articles below for partial unstaking availability.

To Partially Unstake an asset:

1. Sign in to Coinbase Prime.

2. From the portfolio tab, search for the asset.

3. Click the asset to open the asset page. 

4. Under Vault Balance, click the ellipses icon next to the wallet you’d like to use.

   • You must have a vault wallet (cold wallet) set up and a staked balance .

5. Select “unstake” in the Prime UI

6. On the “unstake” page, please select an amount to unstake. 

   • Click on Max Partial Unstake button to select the max amount to be unstaked to ensure the required minimum will remain staked. 

     • Public validator staking (i.e. Delegate staking) minimum required by Coinbase Prime: 11 APT

     • Validator Active set (i.e. Direct staking) minimum requirement (Validator Min.): 1M APT

   • Full unstake button to unstake the entire wallet

   • A Full Unstake or Max Partial Unstake will automatically claim all of your wallets current reward balances.
     

7. After reviewing the information, click “Unstake.”

8. After consensus is reached, each asset is subject to an unbonding period. You can withdraw the asset after it’s unbonded.

   1. Unbonded assets need to be included in a batch before they can be withdrawn. This means you’ll have to wait until the unbonding transaction is included in one of our hourly batches of transactions. 

9. *Please wait for the unstaking process to be completed before initiating another unstaking txn.This process may take up to 14 days.

Entering a Custom Partial Unstake amount (typing an exact number) will automatically claim pending rewards first. The remainder of your requested amount will be unstaked from your wallet’s staked balance.

• For example, if you input 500,000 APT, Prime will first apply any pending rewards toward this amount, with the remainder pulled from principal.

• Claimed rewards and unstaked principal will both go through the protocol-driven unbonding period before becoming fully withdrawable.
