## Integration

Refer `test/testWhole.js` for integration example.

### Get

Get amount in PGT (including multiplier)

API (temporarily): `https://siewchongche.space/predictionGame/getAmountInPGT/?amountInUSD=${amountInUSD}`

Get amount in BNB

API (temporarily): `https://siewchongche.space/predictionGame/getAmountInBNB/?amountInUSD=${amountInUSD}`

> Result might be different when actual claim

### Claim

```
await PGT.claim(userAddress, amountInBNB, amountInPGT, amountInPGTMin, signature, {value: amountInBNB})
```

Call API for parameters

API (temporarily): `https://siewchongche.space/predictionGame/getSignature/?account=${userAddress}&amountInUSD=${amountInUSD}`

Where

`userAddress` = address to claim, only whitelisted address able to claim

`amountInUSD` = amount in USD to claim, options include 50, 100 and 500.

Return `amountInBNB`, `amountInPGT`, `amountInPGTMin` and `signature`.

### Bet (from PGT escrow after claim)

```
await escrow.betBull(1, betAmount, 0, predictionGameAddr)
```

When call with escrow contract, contract will check first if `betAmount` < `escrowPGT`.

If `betAmount` > `escrowPGT`, contract will transfer remaining PGT from user, user need to approve PGT to escrow contract before transfer.

Check user escrow PGT

```
const escrowPGT = await escrow.escrowAmount(userAddress) // 18 decimals
```

### Staking (with BNB)

```
const amountOutMinForDeposit = stakingHelper.getAmountOutMinForDeposit(amountBNBToStake, 1000)
await stakingHelper.deposit(amountOutMinForDeposit, {value: amountBNBToStake})
```

### Claim stake rewards (in PGT)

```
await staking.claim()
```

Check current rewards which avalaible to claim

```
await staking.rewardsOf(userAddress) // In PGT, 18 decimals
```

### Unstake all

```
const amountOutMinForWithdraw = stakingHelper.getAmountOutMinForWithdraw(1000)
await stakingHelper.withdraw(amountOutMinForWithdraw)
```
