How to Partially Unstake SOL on Coinbase Prime

Partial Unstaking allows you to unstake only a portion of your SOL wallet balance while keeping the rest staked. 

How to Partially Unstake Solana on Coinbase Prime:

1. Navigate to the SOL Asset Details Page

2. Locate your SOL wallet: Click the three vertical dots on the right side and select Unstake.

3. Enter the Amount: Input the amount of SOL you wish to unstake and click Continue.

4. Review & Confirm: Review your unstake request transaction details and select Unstake.

5. Consensus Approval: Consensus must be met before the Unstake activity can begin.

6. Transaction Processes: You can monitor progress and the status of the activity on the Activity Details page.

Understanding Your Unstake Request: 

• When will my unstaked assets become available? The unstaked amount can take approximately one day (or in rare edge cases, up to one Solana epoch longer) to become withdrawable.

• What you will see: A partial unstake will show up as two distinct activities in your Prime account history: 

  • The initial “Unstake” activity when the request is completed.

  • The “Withdraw Unbonded” activity when the SOL is ready to be withdrawn. 

• Small balance adjustments: Your vault balance will increase by a small "rent-reserve" amount of 0.00228288 SOL. This is standard behavior when creating the necessary Stake Accounts on the Solana network.

Streamlined Process: These specific steps are due to the orchestration of underlying "Stake Accounts" on the Solana blockchain—complexity that Coinbase Prime manages to ensure a straightforward experience for you.

Fees charged when using the following validator types:

• Coinbase Custody public validator: Not applicable - unable to delegate to validator type

• Coinbase Developer Platform public validator: 8%

• Coinbase Developer Platform dedicated validator: Subscription, participatory, and service fee vary. Reach out to your Account Manager or Prime Operations team for more information

• Consensus requirements: General consensus approvals required for all staking activities

• Withdrawal key: Yes

• Solana credit: 0.05 SOL is credited by Coinbase Prime when you create a wallet. You can’t use the wallet until the credit is added to your account. The credit is used to activate the wallet on the blockchain. You can’t withdraw the credit from your SOL wallet.

• SOL MEV is supported and accumulated interest will be reflected as “rewards”. This will be reflected in all associated reports going forward.

• Please note that while regular staking rewards are auto-compounding, MEV rewards are not auto-compounding due network limitations.
