BlockchainSDK for Godot

The BlockchainSDK is a powerful toolkit for integrating blockchain functionality into your Godot projects. It provides a seamless interface for connecting wallets, managing accounts, interacting with smart contracts, and building decentralized applications (dApps) within the Godot game engine.

Features

• Wallet connection and management
• Network switching (supports multiple blockchains)
• Balance retrieval and real-time updates
• Smart contract interaction (query and execution)
• Event logging and parsing
• UI integration helpers
• Web3 utility functions

Components

The SDK consists of several key components:

1. JsWeb3Node: Base class for Web3 functionality
2. Wallet: Manages wallet connections and account information
3. ContractManager: Handles smart contract interactions
4. Web3Global: Global access point for blockchain operations
5. ContractBase: Abstract base class for contracts
6. Sequence3: Manages promises and contract calls (alongside traditional await methods)

Usage Examples

Creating a Contract Instance

var contract = TemplateErc721Contract.new("0x7D4B7B8CA7E1a24928Bb96D59249c7a5bd1DfBe6")

Converting JSON ABI to Native GDScript

var contract = SimpleNftContract.new("0xbB700D8Ce0D97f9600E5c5f3EF37ec01147Db4b9")
var cm = contract.isApprovedForAll.bind(WalletGlobal.wallet_address, "0x7D4B7B8CA7E1a24928Bb96D59249c7a5bd1DfBe6", true)

Simple Getters with Sequence3

var contract = SimpleSpellCardNftContract.new()
var sequence = Sequence3.new()
sequence.run_async(contract.name.bind(true))
sequence.then_sync(func(args): print(args))
sequence.then_async(func(_args): return contract.owner.bind())
sequence.then_sync(func(args): print(args))

Old Method for Setters

var contract = TemplateErc721Contract.new("0x7D4B7B8CA7E1a24928Bb96D59249c7a5bd1DfBe6")
await contract.bulkSafeMint(WalletGlobal.wallet_address, ["non", "non", "non"])

Old Method for Getters

var contract = TemplateErc721Contract.new("0xF1ddcE4A958E4FBaa4a14cB65073a28663F2F350")
await contract.name(true)

Setters with Sequence

var sequence = Sequence3.new()
sequence.run_async(contract.setApprovalForAll.bind(contract1.contract_address, true))
sequence.run_async(contract1.setMinimumBurnAmount.bind(2))
sequence.then_async(func(_args): return contract1.createPremium.bind([4,5], 6, {"value": Web3Global.contract_manager.parseUnit(0.5)}))

Using Value Parameter

var contract = TemplateBurnNftContract.new()
var contract1 = BurnManagerContract.new()
var sequence = Sequence3.new()
sequence.run_async(contract1.getBurnFee.bind(true))
sequence.then_async(func(burnfee): return contract1.createPremium.bind([10,11], 12, {"value": burnfee.value}))
