# Dragonchain Go SDK

A self-contained Go SDK for interacting with Dragonchain nodes.

## Installation

```bash
go get git.dragonchain.com/dragonchain/dragonchain-prime-sdk-go
```

## Usage

```go
package main

import (
    "context"
    "fmt"
    "log"
    "time"

    "git.dragonchain.com/dragonchain/dragonchain-prime-sdk-go"
    "git.dragonchain.com/dragonchain/dragonchain-prime-sdk-go/models"
)

func main() {
    // Initialize the SDK
    client := sdk.NewDragonchainSDK(
        "your-public-id",
        "your-auth-key-id",
        "your-auth-key",
        "https://your-dragonchain-endpoint.com",
    )

    // Create a context with timeout
    ctx, cancel := context.WithTimeout(context.Background(), 30*time.Second)
    defer cancel()

    // Check system health
    if err := client.System.Health(ctx); err != nil {
        log.Fatal("Health check failed:", err)
    }

    // Get system status
    status, err := client.System.Status(ctx)
    if err != nil {
        log.Fatal("Failed to get status:", err)
    }
    fmt.Printf("Chain ID: %s, Level: %d\n", status.ID, status.Level)

    // Create a transaction
    txn := &models.TransactionCreateRequest{
        TxnType: "my-transaction-type",
        Payload: map[string]interface{}{
            "message": "Hello Dragonchain",
        },
        Tag: "example-tag",
    }

    resp, err := client.Transaction.Create(ctx, txn)
    if err != nil {
        log.Fatal("Failed to create transaction:", err)
    }
    fmt.Printf("Created transaction: %s\n", resp.TransactionID)
}
```

## Available Endpoints

All API methods accept a `context.Context` as their first parameter for timeout and cancellation control.

### System
- `Health(ctx)` - Check system health
- `Status(ctx)` - Get system status

### Transaction
- `Create(ctx, req)` - Create a new transaction
- `CreateBulk(ctx, req)` - Create multiple transactions
- `Get(ctx, transactionID)` - Get transaction by ID
- `List(ctx)` - List all transactions

### Transaction Type
- `Create(ctx, req)` - Create a new transaction type
- `Get(ctx, txnType)` - Get transaction type by name
- `List(ctx)` - List all transaction types
- `Delete(ctx, txnType)` - Delete a transaction type

### Smart Contract
- `Create(ctx, req)` - Create a new smart contract
- `Get(ctx, contractID)` - Get smart contract by ID
- `List(ctx)` - List all smart contracts
- `Update(ctx, contractID, req)` - Update a smart contract
- `Upload(ctx, contractID, filepath)` - Upload smart contract code
- `Delete(ctx, contractID)` - Delete a smart contract

### Block
- `Get(ctx, blockID)` - Get block by ID

## Authentication

The SDK uses HMAC-SHA256 authentication. You need to provide:
- `publicID` - Your Dragonchain public ID
- `authKeyID` - Your authentication key ID
- `authKey` - Your authentication key
- `baseURL` - The base URL of your Dragonchain node (e.g., "https://chains.dragonchain.com")
