How We Deliver

Our Approach for Gwangju Clients

Blockchain technology opens new possibilities for Gwangju businesses — from transparent supply chains to tokenised assets to decentralised applications. We build on Ethereum, Polygon, and other blockchain platforms to create solutions that are secure, transparent, and trustless.

Our development covers smart contracts, decentralised applications (DApps), NFT marketplaces, DeFi platforms, and tokenisation systems. Every smart contract undergoes rigorous security auditing and gas optimisation before deployment. For Gwangju businesses entering Web3, we provide education and strategic guidance alongside technical development.

We handle the full lifecycle: concept validation, architecture design, development, testing, security audit, and mainnet deployment. Post-launch, we provide monitoring and maintenance. Whether you're a Gwangju startup building a Web3 product or an established business exploring blockchain applications, we deliver production-ready solutions.

FAQ

Frequently Asked Questions About Blockchain / Web3 in Gwangju

Everything you need to know about our blockchain / web3 services in Gwangju.

What is a smart contract?
A smart contract is a self-executing contract with terms written directly into code. It automatically enforces agreements when conditions are met.
What is DeFi?

Do you build NFT marketplaces?
Yes, we build custom NFT marketplaces with minting, trading, and auction functionality.
What is the difference between Web2 and Web3?
Web2 is centralised (platforms own user data). Web3 is decentralised (users own their data and assets through blockchain technology).
What blockchains do you develop on?
We primarily develop on Ethereum and Polygon, with experience on Solana, Binance Smart Chain, and Layer 2 solutions like Arbitrum and Optimism.
How do you ensure smart contract security?
We conduct internal audits, use formal verification tools like Slither and MythX, and engage third-party auditors before mainnet deployment.
What is gas optimisation?
Gas optimisation is the practice of writing efficient smart contract code that minimises transaction fees on the blockchain.
Do you build dApps (decentralised applications)?
Yes, we build full-stack dApps with smart contract backends and intuitive frontends using React, wagmi, and ethers.js.
What is tokenomics?
Tokenomics is the study of token economics — including token supply, distribution, utility, and incentives — that drives a token-based ecosystem.
Do you offer blockchain consulting?
Yes, we help businesses evaluate blockchain feasibility, choose the right platform, and design token-based business models.
What is an audit trail on blockchain?

Layer 2 solutions process transactions off the main blockchain (Layer 1) to reduce fees and increase speed while inheriting its security.
Do you develop crypto wallets?
Yes, we build custom wallet applications for storing, sending, and receiving cryptocurrencies and tokens.
What is Web3 authentication?
Web3 authentication uses wallet signatures (like MetaMask) instead of passwords, giving users control of their identity.
How do you test blockchain applications?
We write comprehensive unit tests with Foundry, deploy on testnets, run integration tests, and conduct security audits before mainnet deployment.
What is a DAO (Decentralised Autonomous Organisation)?
A DAO is an organisation governed by smart contracts and community voting, with decisions made collectively by token holders.
