YSK Limited builds enterprise Web3 systems: Solidity smart contracts, cryptocurrency payment gateways, DApps, and Avalanche/NEAR public-chain node hosting. Work is scoped under remote-dev or custom projects and quoted from a specification.
There is no room for error in Web3. We insist on the strictest code audits and architecture design so your crypto assets and decentralised operations stay fully protected.
Focused on Ethereum and major EVM-compatible chains. Whether issuing enterprise tokens (ERC-20), designing NFT drops (ERC-721/1155), or building DeFi logic, we deliver solid Solidity code with aggressive gas optimisation.
Help traditional e-commerce or platforms connect seamlessly to Web3. Integrate MetaMask, WalletConnect, and similar wallets, and build dedicated USDT/USDC payment and settlement gateways.
Hands-on experience operating Avalanche and NEAR validators. Enterprise RPC node setup, private-chain deployment, and 99.99% uptime performance maintenance.
From smart contracts to user-friendly web frontends — complete decentralised experiences. Wallet connect, on-chain data reads, NFT galleries, and other Web3 interactions so your project can go live on mainnet with confidence.
In blockchain, code is law. Our process puts security first.
Before writing any contract, our Web3 architects plan mechanisms, tokenomics, and deflation models with you — ensuring on-chain logic is commercially viable.
Senior engineers write Solidity and deploy to testnets (Goerli / Sepolia, etc.) for weeks of extreme stress testing — correct function logic and minimal gas consumption.
Internal security teams run white-box testing and reentrancy-style vulnerability checks so contracts resist attacks and protect enterprise and user assets.
Contracts deploy to mainnet with open-source verification. We continue DApp frontend updates, RPC node maintenance, and 24/7 on-chain monitoring for long-term stability.
Direct answer: Yes. We develop Solidity smart contracts.
Direct answer: Yes. This page includes cryptocurrency payment gateway integration.
Direct answer: Yes. We can host and operate Avalanche/NEAR nodes.
Direct answer: No. Web3 is one YSK development service; websites and apps are on the Hong Kong app development page.
Whether issuing enterprise tokens, building a decentralised app, or hosting dedicated nodes — our blockchain specialists are ready.
