+## Destroying nomination pool
+
+Destroying a nomination pool involves a series of steps.

+For a more convenient way to destroy a pool, consider using [NFT.io](https://nft.io).

+
+To manually destroy a pool using the Enjin Console, follow these steps:
+1. **Change the Pool State to Destroying**: Initiate the destruction process by setting the pool's state to `Destroying`. You can do this by calling the `nominationPools.destroy()` extrinsic.
+2. **Unbond Member Stakes**: If any members have staked funds in the pool, their stakes must be unbonded. Once the pool is in the `Destroying` state, the `nominationPools.unbond()` extrinsic becomes permissionless. This means the pool owner can initiate unbonding for all members by calling `nominationPools.unbond()` on their behalf. After the unbonding period for all members ends, their stakes must be withdrawn using the `nominationPools.withdrawUnbonded()` extrinsic, which is also permissionless at this stage.
+3. **Unbond and Withdraw the Initial Deposit**: Once the pool is in the `Destroying` state and has no bonded members, the pool owner must unbond their initial ENJ stake deposit. Do this by calling the `nominationPools.unbondDeposit()` extrinsic. After the unbonding period for the deposit ends, use the `nominationPools.withdrawDeposit()` extrinsic to withdraw it and finalize the pool's destruction.
