thirdweb Go SDK

Installation

To install the SDK with the go get command, run the following:

go get github.com/thirdweb-dev/go-sdk/thirdweb

Getting Started

To start using this SDK, you just need to pass in a provider configuration.

Instantiating the SDK

Once you have all the necessary dependencies, you can follow the following setup steps to get started with SDK read-only functions:

package main

import (
    "fmt"

    "github.com/thirdweb-dev/go-sdk/thirdweb"
)

func main() {
    // Creates a new SDK instance to get read-only data for your contracts, you can pass:
    // - a chain name (mainnet, rinkeby, goerli, polygon, mumbai, avalanche, fantom)
    // - a custom RPC URL
    sdk, err := thirdweb.NewThirdwebSDK("mumbai", nil)
    if err != nil {
        panic(err)
    }

    // Now we can interact with the SDK, like displaying the connected chain ID
    chainId, err := sdk.GetChainID()
    if err != nil {
        panic(err)
    }

    fmt.Println("New SDK instance create on chain", chainId)
}

Working With Contracts

Once you instantiate the SDK, you can use it to access your thirdweb contracts. You can use SDK's contract getter functions like GetNFTCollection, GetEdition, and GetNFTDrop, to get the respective SDK contract instances. To use an NFT Collection contract for example, you can do the following.

package main

import (
    "fmt"

    "github.com/thirdweb-dev/go-sdk/thirdweb"
)

func main() {
    sdk, err := thirdweb.NewThirdwebSDK("mumbai", nil)
    if err != nil {
        panic(err)
    }

    // Add your NFT Collection contract address here
    address := "0x..."
    nft, err := sdk.GetNFTCollection(address)
    if err != nil {
        panic(err)
    }

    // Now you can use any of the read-only SDK contract functions
    nfts, err := nft.GetAll()
    if err != nil {
        panic(err)
    }

    fmt.Printf("%d NFTs found on this contract\n", len(nfts))
}

Signing Transactions

In order to execute transactions on your contract, the SDK needs to know the wallet that is performing those transactions. For that it needs the private key of the wallet you want to execute transactions from.

⚠️ Never commit private keys to file tracking history, or your account could be compromised.

To connect your wallet to the SDK, you can use the following setup:

package main

import (
    "fmt"
    "encoding/json"

    "github.com/thirdweb-dev/go-sdk/thirdweb"
)

func main() {
    // Get your private key securely (preferably from an environment variable)
    privateKey := "..."

    // Instantiate the SDK with your privateKey
    sdk, err := thirdweb.NewThirdwebSDK("mumbai", &thirdweb.SDKOptions{
        PrivateKey: privateKey,
    })
    if err != nil {
        panic(err)
    }

    // Replace your contract address here
    address := "0x..."
    nft, err := sdk.GetNFTCollection(address)
    if err != nil {
        panic(err)
    }

    // Now you can execute transactions using the SDK contract functions
    tx, err := nft.Mint(
        &thirdweb.NFTMetadataInput{
            Name:        "Test NFT",
            Description: "Minted with the thirdweb Go SDK",
            Image: "ipfs://QmcCJC4T37rykDjR6oorM8hpB9GQWHKWbAi2YR1uTabUZu/0",
        },
    )
    if err != nil {
        panic(err)
    }

    result, _ := json.Marshal(&tx)
    fmt.Println(string(result))
}
