Talk to Klaytn Developer
It is possible to trace the beginning of smart contracts back to the 1990s when an early cryptographer named Nick Zabo introduced them. He explained that these machines accept money and distribute goods following the posted prices; there is no need for an intermediary. He compared these machines to the rudimentary forebears of today's sophisticated smart contracts. Vending machines accept money and distribute goods following the prices that are posted. In a manner akin to this, smart contracts in the domain of cryptocurrencies receive payments from users in the form of something referred to as gas fees, and transactions are automatically carried out by computer code once criteria are reached.
Now, if you'll indulge us, we'd like to show you a demonstration of one of the simplest methods for implementing a smart contract on the Klaytn network.
Klaytn is a business blockchain platform built by the firm Kakao, a South Korean internet service provider. Its modular network architecture is designed to simplify businesses constructing and managing their service-oriented blockchains built atop the Klaytn architecture. This is made possible by the architecture's modularity.
A smart contract is a program Klaytn uses to construct business logic, games, libraries, token transfers, or any other kind of code that interacts with the Klaytn blockchain. In Klaytn, a smart contract can take the form of any of these things. "smart contracts" can also be used interchangeably with "smart agreements."
For the time being, Klaytn only offers support for the programming language known as Solidity when developing smart contracts. Because Solidity is the de facto standard for the programming language used to generate smart contracts on Ethereum because it has a large user base, and because its community is quite active, Klaytn decided to choose Solidity as the language that would be utilized in Klaytn.
Klaytn is a public blockchain platform that is designed to be user-friendly and suitable for a wide range of applications and smart contract development. As, it is backed by Kakao, a major South Korean internet company, which could help to attract a large user base to the platform. This could make it easier for smart contract developers to find users for their smart contracts and dApps.
To start things moving, we will need a few essential items. The links are provided for all the essential tools required.
The Klaytn sandbox is a template piece of code that assists developers as they begin the process of building decentralized applications (Dapps) on the Klaytn blockchain. Sandbox uses the Truffle framework to compile, deploy, and test smart contracts.
Let's get started by cloning the sandbox repository, then proceed to install any necessary libraries.
Any editor may be used to access the klaytn-dev-sandbox folder. For the sake of this specific illustration, we made use of VsCode. The following directory structure should appear for you to view within your editor:
There are just a few exemplary digital contracts in the contracts area. The migrations folder has all the essential deployment scripts for deploying any smart contract. The scripts required to set up a local Klaytn network are located in the network subdirectory of the file system. The code required to develop a user interface for the Dapp may be found within the source folder.
We will need an environment where our contracts may be implemented to get started. During the project stage, where development occurs, the most advantageous course of action is to use a local blockchain system comparable to Ganache. It will run on your personal computer, will not require a connection to the internet, and will provide you with ten test accounts to use to complete our business transactions.
If you use the command below, setting up a local Klaytn network should not provide you with significant challenges. The deployment of one Klaytn consensus node is part of the basic setup.
To see the execution logs, run npm run run:klaytn:log
To stop the network, run npm run run:klaytn:stop
To resume the network, run npm run run:klaytn:resume
To completely terminate the network, run npm run run:klaytn:terminate
To remove log files, run npm run:klaytn:cleanlog
It is possible that reviewing the example contracts contained within our project's contracts directory will provide us with a head start. For simplicity, we have included a breakdown of the fundamental contracts required to create fungible and non-fungible tokens. By putting these sample contracts into action on our network and using the functionality they provide, we can transfer tokens.
You'll find that we can make not only use of the pre-existing smart contracts but also create our own. This information may be found within the folder labeled "contracts." For instance:
The KlaytnGreeter smart contract is a simple piece of software that works by generating and then returning a greeting message to the user. The configuration of the welcoming message takes place at the initial deployment of the contract.
You need to save the code just discussed in a file known as KlaytnGreeter.sol, which can be found in the folder designated for contracts. The next step is to construct the smart contract, and after it is complete, you will need to deploy it within the local network.
Before we go on to anything further, let's give the smart contract that we just finished building a test run with the help of a deployment script which you can find in the Migrations directory. The construction and deployment of the KlaytnGreeter contract on the local network will be handled by the code shown below. In addition, for future reference, the ABI and the address of the location where the contract was deployed will be preserved in the source folder.
The code displayed up top may be copied, and the file should be saved with the name 5 greeter migration.js. To put the contract into effect, use the instruction provided further down.
You will see the below logs once it’s deployed successfully.
If the deployment was carried out without a hitch, the deployed ABI and address files would be generated in the src folder, located directly below the deployed directory.
Scale your Klaytn projects with us
Using the KAS (Klaytn API Service), a public node service that is comparable to Infura, it is possible to gain access to a testnet in a way that is both speedy and uncomplicated. KAS provides users of the main network and testnets with access to public Klaytn nodes by providing free alternatives and paid subscriptions to users of the service.
The output of the deployed ABI and address files that were produced can be seen below, and the files themselves can be discovered in the folder labeled src/deployed.
Because Klaytn blockchain is open source, anybody who wants to build something, work in the metaverse development company, or even play there for free can utilize it. During the subsequent stage of Klaytn's development, we will provide the performance, decentralization, scalability, and interoperability necessary for driving the trust layer of the metaverse.
We have built a comprehensive bundle to ease the transfer into the world of blockchain technology for the builders of metaverses in the most efficient and uncomplicated manner that is physically feasible.
Scale your Klaytn Project with us
One popular thing many developers do is to build the same solution existing on other blockchains on the less known blockchains like Klaytn. There are no limits to what you can achieve when you work with blockchain development experts to build these solutions with sustainability in mind. Our blockchain experts are master adapters of codes and technologies able to design useful solutions off their feet.
The Klaytn project is an open-source and public blockchain initiative that works toward being the fundamental trust layer for the metaverse. To achieve this goal, it recognizes the participation and contributions made by all communities. As a result, these communities are granted more authority and brought closer together in the new world.
