🛠 A Go SDK for building applications on top of Pancake V3

## Installation

```sh

go get github.com/KyberNetwork/pancake-v3-sdk

```

## Usage

The following example shows how to create a pool, and get the inputAmount

```go

package main

import (

	"fmt"

	"math/big"

	core "github.com/daoleno/uniswap-sdk-core/entities"

	"github.com/KyberNetwork/pancake-v3-sdk/constants"

	"github.com/KyberNetwork/pancake-v3-sdk/entities"

	"github.com/KyberNetwork/pancake-v3-sdk/utils"

	"github.com/ethereum/go-ethereum/common"

)

var (

	USDC     = core.NewToken(1, common.HexToAddress("0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48"), 6, "USDC", "USD Coin")

	DAI      = core.NewToken(1, common.HexToAddress("0x6B175474E89094C44Da98b954EedeAC495271d0F"), 18, "DAI", "Dai Stablecoin")

	OneEther = big.NewInt(1e18)

)

func main() {

	// create demo ticks

	ticks := []entities.Tick{

		{

			Index:          entities.NearestUsableTick(utils.MinTick, constants.TickSpacings[constants.FeeLow]),

			LiquidityNet:   OneEther,

			LiquidityGross: OneEther,

		},

		{

			Index:          entities.NearestUsableTick(utils.MaxTick, constants.TickSpacings[constants.FeeLow]),

			LiquidityNet:   new(big.Int).Mul(OneEther, constants.NegativeOne),

			LiquidityGross: OneEther,

		},

	}

	// create tick data provider

	p, err := entities.NewTickListDataProvider(ticks, constants.TickSpacings[constants.FeeLow])

	if err != nil {

		panic(err)

	}

	// new pool

	pool, err := entities.NewPool(USDC, DAI, constants.FeeLow, utils.EncodeSqrtRatioX96(constants.One, constants.One), OneEther, 0, p)

	if err != nil {

		panic(err)

	}

	// USDC -> DAI

	outputAmount := core.FromRawAmount(DAI, big.NewInt(98))

	inputAmount, _, err := pool.GetInputAmount(outputAmount, nil)

	if err != nil {

		panic(err)

	}

	fmt.Println(inputAmount.ToSignificant(4))

}

```
