集成说明

对于钱包、中心化交易所（CEX）以及其他想要集成 Stacking DAO 存取逻辑的协议，有三个关键方法需要了解：

1. 存入 STX（Deposit）

The deposit method can be initiated using the deposit method on the SP4SZE494VC2YC5JYG7AYFQ44F5Q4PYV7DVMDPBG.stacking-dao-core-v4 contract.

This contract expects the following parameters

• reserve-contract - 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-v2`

• 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

1. 发起提取（Init-Withdraw）

When withdrawing, users can follow a two-step process, see https://docs.stackingdao.com/stackingdao/the-stacking-dao-app/withdrawing-stx for more information.

The initialisation of a withdrawal can be called using init-withdraw and expects the following parameters:

• reserve-contract - 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-v2`

• 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).

1. 完成提取（Withdraw）

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a given init-withdrawal call (but always before the last 288 blocks of a given cycle), the STX principal + yield can be withdrawn from Stacking DAO.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-contract - 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.
