Aptos (APT) staking guide on Coinbase Prime

Coinbase Prime allows you to delegate your APT to a public validator or stake directly to your own dedicated validator. 

  • Public Validator: Delegated staking can enable you to earn rewards by delegating your APT tokens to a public node to earn a percentage of the block rewards earned by the validator. You can do this directly in Coinbase Prime.  

  • Dedicated Validator: Coinbase Prime supports the ability to stake, restake rewards, unstake part of your staked wallet, as well as the ability to change your validator of choice or the commission fee, and change the voter for your validator.  If you intend to stake to your own dedicated validator or require dedicated validator services, please reach out to your sales contact or account manager to facilitate these transactions.

The following article focuses on staking to a Public Validator through Coinbase Prime.

Ability to stake when using the following entity:

  • Coinbase Custody Trust Company, LLC: Yes

  • Coinbase Custody International, Ltd.: Yes

  • Coinbase Germany GmBH: 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 30 days.

  • Warm up period:  The validator becomes active and starts to earn rewards once the minimum is met and the next 30 day lockup period begins. 

  • Bonding/Unbonding period: 

  1. Staking runs on 30 day lockup periods from when the period starts. The 30 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.
