# 4swap SDK go

## 4swap

[4swap](https://4swap.org) is a decentralized protocol implement for automated liquidity provision on [Mixin Network](https://mixin.one)

## Install

```bash

go get github.com/fox-one/4swap-sdk-go/v2

```

### Authorization

4swap supports two kinds of access tokens:

1. the access token that complete the OAuth flow at 4swap's webpage: https://app.4swap.org

2. the access token that generated by your own Mixn Application. The token should sign the URL **/me** and the scope should be "FULL". Please read this [document](https://developers.mixin.one/docs/dapp/guide/generate-jwt-token) for more details.

### Example

```golang

func TestPreOrder(t *testing.T) {

    ctx := context.Background()

    c := New()

    c.UseToken("your auth token")

    

    pairs, err := c.ListPairs(ctx)

    if err != nil {

        t.Fatal(err)

    }

    

    req := &PreOrderReq{

        PayAssetID:  "4d8c508b-91c5-375b-92b0-ee702ed2dac5",

        FillAssetID: "31d2ea9c-95eb-3355-b65b-ba096853bc18",

        PayAmount:   decimal.NewFromFloat(0.1),

    }

    

    preOrder, err := PreOrderWithPairs(pairs, req)

    if err != nil {

        t.Fatal(err)

    }

    

    t.Logf("fill amount: %s", preOrder.FillAmount)

    

    followID := uuid.NewString()

    minAmount := preOrder.FillAmount.Mul(decimal.NewFromFloat(0.99)).Truncate(8)

    memo := BuildSwap(followID, req.FillAssetID, preOrder.Paths, minAmount)

    

    t.Logf("memo: %s", memo)

    

    group, err := c.ReadGroup(ctx)

    if err != nil {

        t.Fatal(err)

    }

    

    t.Logf("target mix address: %s", group.MixAddress)

    

    transfer := &mixin.TransferInput{

        AssetID:    req.PayAssetID,

        OpponentID: group.MixAddress,

        Amount:     req.PayAmount,

        TraceID:    followID,

        Memo:       memo,

    }

    

    t.Log(mixin.URL.SafePay(transfer))

    

    // transfer pay asset to mix address

    

    // view order detail

    order, err := c.ReadOrder(ctx, followID)

    if err != nil {

        assert.True(t, IsErrorCode(err, 401))

    } else {

        t.Logf("order state: %s", order.State)

    }

}
