# stSTX: Stacking DAO Core V6 Stacking DAO Core V6 is the main entry point for all user-related actions such as depositing and withdrawing STX, looking up the stSTX/STX ratio or a withdrawal NFT position of a user. The contract can be found here: **Integrations** For wallets, CEXes and other protocols who want to integrate the Stacking DAO deposit/withdrawal logic, there are three important methods to take into account: 1. **Deposit** The deposit method can be initiated using the `deposit` method on the `SP4SZE494VC2YC5JYG7AYFQ44F5Q4PYV7DVMDPBG.stacking-dao-core-v6` contract. This contract expects the following parameters * `reserve` - this is the Stacking DAO reserve contract, and should always be set to \``SP4SZE494VC2YC5JYG7AYFQ44F5Q4PYV7DVMDPBG.reserve-v1` * `commission-contract` - this is the Stacking DAO commission contract, and should always be set to \``SP4SZE494VC2YC5JYG7AYFQ44F5Q4PYV7DVMDPBG.commission-v2` * `staking-contract` - this is the Stacking DAO staking contract, and should always be set to \``SP4SZE494VC2YC5JYG7AYFQ44F5Q4PYV7DVMDPBG.staking-v0` * `direct-helpers` - this is the Stacking DAO direct helpers contract, and should always be set to \``SP4SZE494VC2YC5JYG7AYFQ44F5Q4PYV7DVMDPBG.direct-helpers-v4` * `stx-amount` - a positive integer value for the uSTX (micro-STX, 10^6) amount you want to stack and get `stSTX` in return for. For example, passing `1000000` will stack 1 STX. * `referrer` - an optional Stacks address, this accumulates referral points on the leaderboard * `pool` - should be set to `none` for now 2. **Initiate Withdrawal** When withdrawing, users can follow a two-step process, see for more information. The initialisation of a withdrawal can be called using `init-withdraw` and expects the following parameters: * `reserve` - this is the Stacking DAO reserve contract, and should always be set to \``SP4SZE494VC2YC5JYG7AYFQ44F5Q4PYV7DVMDPBG.reserve-v1` * `direct-helpers` - this is the Stacking DAO direct helpers contract, and should always be set to \``SP4SZE494VC2YC5JYG7AYFQ44F5Q4PYV7DVMDPBG.direct-helpers-v4` * `ststx-amount` - a positive integer value for the ustSTX (micro-stSTX, 10^6) amount you want to unstack and get `STX` in return for. For example, passing `1000000` will unstack 1 stSTX. When this call succeeds, the user will receive an NFT that represents their unstacking position and indicates the amount of STX they should receive after a given PoX cycle ends (this is always principal + yield). 3. **Withdrawal** Finally, once the PoX cycle ends after a given `init-withdrawal` call (but always before the last 288 blocks of a given cycle), the STX principal + yield can be withdrawn from Stacking DAO. The withdrawal can be called using `withdraw` and expects the following parameters: * `reserve` - this is the Stacking DAO reserve contract, and should always be set to \``SP4SZE494VC2YC5JYG7AYFQ44F5Q4PYV7DVMDPBG.reserve-v1` * `commission-contract` - this is the Stacking DAO commission contract, and should always be set to \``SP4SZE494VC2YC5JYG7AYFQ44F5Q4PYV7DVMDPBG.commission-v2` * `staking-contract` - this is the Stacking DAO staking contract, and should always be set to \``SP4SZE494VC2YC5JYG7AYFQ44F5Q4PYV7DVMDPBG.staking-v0` * `nft-id` - the ID of the NFT that was minted in the `init-withdraw` method previously. After the withdrawal succeeds, the STX principal and yield amounts will be returned to the transaction sender's wallet. 4. **Instant Withdrawal** Instant withdrawal lets you withdraw your STX immediately using idle liquidity from the protocol, if idle liquidity is available. A 1% fee applies to Instant Unstack. The instant withdrawal can be called using `withdraw-idle` and expects the following parameters: * `reserve` - this is the Stacking DAO reserve contract, and should always be set to \``SP4SZE494VC2YC5JYG7AYFQ44F5Q4PYV7DVMDPBG.reserve-v1` * `direct-helpers` - this is the Stacking DAO direct helpers contract, and should always be set to \``SP4SZE494VC2YC5JYG7AYFQ44F5Q4PYV7DVMDPBG.direct-helpers-v4` * `commission-contract` - this is the Stacking DAO commission contract, and should always be set to \``SP4SZE494VC2YC5JYG7AYFQ44F5Q4PYV7DVMDPBG.commission-v2` * `staking-contract` - this is the Stacking DAO staking contract, and should always be set to \``SP4SZE494VC2YC5JYG7AYFQ44F5Q4PYV7DVMDPBG.staking-v0` * `ststx-amount` - a positive integer value for the ustSTX (micro-stSTX, 10^6) amount you want to unstack and get `STX` in return for. For example, passing `1000000` will unstack 1 stSTX.
