## 质押

```ts theme={null}
import { ONE_ALPH } from '@alephium/web3'

const tx = await powfi.staking.stakeAlph(100n * ONE_ALPH)
```

交易会附加 `amount + MINIMAL_CONTRACT_DEPOSIT` 的 ALPH。要把质押归属到某个渠道地址，请使用 `stakeAlphWithReferral(amount, referral)`。使用 referral 之前请先联系团队，见[推荐质押与渠道分润](/zh/guides/referral-staking)。

## 显示兑换率和用户持仓价值

```ts theme={null}
import Decimal from 'decimal.js'

const { fields } = await powfi.staking.getXAlphTokenState()
const rate = new Decimal(fields.totalDepositedAlph.toString()).div(fields.totalXAlphSupply.toString()) // ALPH per xALPH

const xAlphId = powfi.staking.getConfig().xAlphTokenId
const bal = await powfi.nodeProvider.addresses.getAddressesAddressBalance(address)
const xAlph = BigInt(bal.tokenBalances?.find((t) => t.id === xAlphId)?.amount ?? '0')
const valueInAlph = rate.mul(xAlph.toString()).div(1e18) // xALPH has 18 decimals, like ALPH
```

## 解除质押

```ts theme={null}
await powfi.staking.startUnstake(50n * ONE_ALPH) // amount of xALPH to burn
```

这会开启一个新的解除质押金库。ALPH 在 `getSettings().unstakeDuration`（主网为 30 天）内线性解锁：已解锁的部分随时可以领取，期满后可领取全部。每个用户最多有 16 个活跃请求。

## 列出待处理的请求

```ts theme={null}
const indexes = await powfi.staking.getActiveUnstakeVaultIndexes(address)

const requests = await Promise.all(
  indexes.map(async (i) => {
    const { fields } = await powfi.staking.getAlphUnstakeVaultState(address, i)
    return {
      index: i,
      total: fields.totalUnstakeAmount,
      withdrawn: fields.withdrawnAmount,
      fullyUnlockedAt: new Date(Number(fields.unstakeStartTime + fields.unstakeDuration)),
      claimable: await powfi.staking.getClaimableAmount(address, i)
    }
  })
)
```

## 领取或取消

```ts theme={null}
for (const r of requests) {
  if (r.claimable > 0n) await powfi.staking.claimUnstaked(r.index, r.claimable)
}

// change of mind: unlocked ALPH is paid out, the rest is re-staked as xALPH
await powfi.staking.cancelUnstake(requests[0].index)
```
