# OPB SDK GO

IRITA 开放联盟链 SDK（Golang）

## 快速开始

### 引入依赖

编辑 go.mod

```
replace (
	github.com/gogo/protobuf => github.com/regen-network/protobuf v1.3.2-alpha.regen.4
	github.com/tendermint/tendermint => github.com/bianjieai/tendermint v0.34.1-irita-210113
	github.com/prometheus/common => github.com/prometheus/common v0.26.0
)

require (
	github.com/irisnet/core-sdk-go v0.0.0-20220720085949-4d825adb8054
	github.com/irisnet/irismod-sdk-go v0.0.0-20220825063058-6bf8e60b42c8
	github.com/bianjieai/iritamod-sdk-go v0.0.0-20220708032705-9e8e301da3a8
	github.com/stretchr/testify v1.7.0
	google.golang.org/grpc v1.40.0
)
```

### 创建和使用 OPB 客户端

参考 [示例代码](./examples/main.go)

```go
package main

import (
	"fmt"
	"time"

"github.com/irisnet/irismod-sdk-go/mt"
	"github.com/irisnet/irismod-sdk-go/nft"

"github.com/irisnet/irismod-sdk-go/record"

opb "github.com/bianjieai/opb-sdk-go/pkg/app/sdk"
	"github.com/bianjieai/opb-sdk-go/pkg/app/sdk/model"
	"github.com/irisnet/core-sdk-go/types"
	"github.com/irisnet/core-sdk-go/types/store"
	tendermintTypes "github.com/tendermint/tendermint/abci/types"
)
