 ## Stopping Solo Stacking
 
-When stacking solo using the `stack-stx` function, your STX tokens are locked for a fixed period (the lock period) defined when you initiated stacking. **No additional action is required to stop stacking.** Simply wait until the lock period expires.

 ## Stopping Pooled Stacking
 
-If you're stacking with a pool (where you delegate your STX via the `delegate-stx` function), the process to stop stacking requires one extra step before the tokens are eventually unlocked.

 ### Step 1: Revoke Delegation
 
-Before your tokens can be unlocked, you must cancel the delegation with the pool operator. This is done by calling the `revoke-delegate-stx` function through the pool's interface, or within the [pox-4](https://explorer.hiro.so/txid/SP000000000000000000002Q6VF78.pox-4?chain=mainnet) contract.

-Calling `revoke-delegate-stx` cancels your STX delegation, revoking the pool's access to further lock/stack your funds. Even after revoking the delegation, your STX will remain locked until the end of the last stacking cycle chosen by the pool.
+Calling `revoke-delegate-stx` cancels your STX delegation, revoking the pool operator's access to further lock/stack your funds. Even after revoking the delegation, your STX will remain locked until the end of the last stacking cycle chosen by the pool (can be at most 12 cycles in the future).
 
 {% hint style="warning" %}
 Failing to revoke your delegation will mean that you continue to allow the pool to stack your STX until the reach of the burn block height mentioned in the delegate function (`delegate-stx`). Ensure that you have successfully called `revoke-delegate-stx` if you want to stop stacking sooner.
 {% endhint %}
 
 ### Step 2: Wait for Funds to Unlock
-After revoking your delegation, your STX tokens will still remain locked until the last stacking cycle chosen by the pool completes. The unlock occurs automatically at the predefined unlock burn height for that cycle.

 Even in pooled stacking, the unlocking mechanism follows the same blockchain timing as solo stacking. Revoking delegation only stops future stacking actions, it does not immediately unlock your tokens.

 ## Considerations
 - Monitor Your Stacking Status: Use your wallet's interface or the [Hiro Explorer](https://explorer.hiro.so?chain=mainnet) to track the status of your lock period and confirm when your tokens are available.
+- Using the API: Hiro's API offers an endpoint to [Get account STX balance](https://docs.hiro.so/stacks/api/accounts/stx-balances), which contains the `burnchain_unlock_height` height, representing the burn block height where your STX unlocks.
 - Plan Ahead: Since the unlocking is bound to cycle's timing, plan your stacking period or revocation accordingly to minimize delays in accessing your funds.
