### Get Campaign Start Time (JavaScript)

Source: https://tapp-exchange.gitbook.io/tapp-exchange/developer-docs/sc

Fetches the start timestamp of a campaign. Inputs include the pool address and campaign index. The `aptos.view` method is used to query the smart contract for this information.

```javascript
const startTime = await aptos.view({
    function: `${viewAddress}::stable_views::get_campaign_start_time`,
    type_arguments: [],
    arguments: [poolAddress, campaignIndex],
});
```

### Create Stable Pool Example

Source: https://tapp-exchange.gitbook.io/tapp-exchange/developer-docs/sc

This example shows how to serialize parameters for creating a Stable pool. It covers pool type, assets, fee, amplification factor, off-peg multiplier, initial amounts for each coin, and the minimum LP mint amount. The amplification factor must be between 100 and 1000.

```typescript
// pool type
ser.serializeU8(4);

// assets, support up to 4 coins.
ser.serializeVector([AccountAddress.fromString(coinA), AccountAddress.fromString(coinB)]);

// fee 1_000_000 for 0.01%, and 5_000_000 for 0.05%
ser.serializeU64(fee);

// amp. Between 100 to max 1000
ser.serializeU256(amp);

// off peg multiplier
ser.serializeU256(offpeg_fee_multiplier);

// Initial liquidity for each coins
ser.serializeVector(amounts.map(amount => new U256(amount)));

// minimum LP mint amount
ser.serializeU256(min_mint_amount);
```

--------------------------------

### AMM Swap Example

Source: https://tapp-exchange.gitbook.io/tapp-exchange/developer-docs/sc

This example demonstrates the serialization process for performing an AMM swap. It includes the pool ID, swap direction (token A to B or vice-versa), whether the input amount is fixed, the input amount, and the minimum expected output amount. This is used for functions like `swap_exact_tokens_for_tokens` or `swap_tokens_for_exact_tokens`.

```typescript
// pool id
ser.serialize(AccountAddress.fromString(poolId));

// swap from tokenA to tokenB
ser.serializeBool(aToB);

// fixed_amount_in.
// True = swap_exact_tokens_for_tokens
// False = swap_tokens_for_exact_tokens
ser.serializeBool(fixed_amount_in);


// amount in
ser.serializeU64(amountIn);

// minimum amount out
ser.serializeU64(amountOutMin);
```

## Swap

### Estimate Swap Amount

Estimates the amount received or needed for a swap, depending on input direction.

**Params**

* `amount`: `number` The amount for estimation (used as input or desired output depending on `field`).
* `poolId`: `string` The identifier of the pool.
* `pair`: `[number, number]` A tuple of token indexes to swap, e.g., `[0, 1]` means token at index 0 is being swapped for token at index 1.
* `a2b`: `boolean` Swap direction — `true` for token at `pair[0]` to `pair[1]`, `false` for `pair[1]` to `pair[0]`.
* `field` (optional): `input | output` Indicates if `amount` is an "input" or "output" amount (defaults to "input").

```ts
const getEstSwap = async () => {
    const result = await sdk.Swap.getEstSwapAmount({
        poolId: "0xpool",
        a2b: true,
        field: 'input', // input or output
        amount: 1000000000,
        pair: [0, 1]
    });
    
    if(result.error instanceof TradeSizeExceedsError) {
        console.error(result.error.message)
        console.error('max allowed amount', result.error.maxAmountIn);
    }

    console.log(result);
};
```

### Get Swap Route

Retrieves the pool route information between two tokens.

Use `sdk.Swap.getRoute` method

**Example**

```ts
async function getRoute() {
    const token0 = '0xtoken1'
    const token1 = '0xtoken2'
    const poolInfo = await sdk.Swap.getRoute(token0, token1);

    console.log(poolInfo)
}
```

### AMM Swap

Creates a swap payload for an AMM pool

Use `sdk.Swap.swapAMMTransactionPayload` method

**Params:**

* `poolId`: `string` The address of the pool in which the swap is performed.
* `a2b`: `boolean` Direction of the swap; `true` for token A to B, `false` for B to A.
* `fixedAmountIn`: `boolean` Whether the input amount is fixed (defaults to `true`).
* `amount0`: `number` Amount of token A.
* `amount1`: `number` Amount of token B.

```ts
const { signAndSubmitTransaction, account } = useWallet();

async function swapAMM() {
    const params: SwapAMMParams = {
        poolId: '0xpool',
        a2b: true,
        fixedAmountIn: true,
        amount0: 100000000,
        amount1: 10000000,
    }
    const data = sdk.Swap.swapAMMTransactionPayload(params);

    });
}
```

### Creating a Pool

Source: https://tapp-exchange.gitbook.io/tapp-exchange/developer-docs/amm

Details the process and parameters required for creating a new AMM pool.

```APIDOC
## Creating a Pool

Pools are created with `create_pool(pool_signer, assets, fee, creator)`.

* `pool_signer` is the signer of the newly created account that will store the `Pool` resource.
* `assets` is a vector with two addresses representing the coin types of token A and token B.
* `fee` must match one of the configured fee tiers (0.01%, 0.05%, 0.3% or 1%).
* `creator` is recorded in the `PoolCreated` event.

The function initializes reserves to zero and sets `total_shares` to zero. No liquidity exists until someone calls `add_liquidity`.
```
