dApp Software Development Company for DeFi, NFT & Enterprise Solutions
KISS Software delivers full-cycle dApp development for Web3, decentralized finance, NFTs, and enterprise blockchain systems. We build secure smart-contract–based backend logic, Web interfaces with wallet connectivity, and scalable architectures powered by Ethereum, BNB Chain, Polygon, and other networks.
Why should you launch a dApp today?
-
Full control over assetsSmart contracts eliminate intermediaries and provide reliable, trustless logic.
-
NFT, DAO, DeFi, and games
We implement any scenario end-to-end.
-
Transparency and openness
Code, logic, and tokens are verifiable by the community.
What we do for you
Requirements analysis & blockchain selection
We analyze your business logic and select the optimal blockchain: EVM networks, Layer 2 solutions, or private chains.
Tokenomics & smart contract architecture
We design the dApp structure: smart contracts, tokens, role models, and permission systems. DeFi, NFT, and DAO models supported.
Smart contract development & audit
We write secure contracts, perform manual and automated testing, and conduct internal or third-party audits.
Web3 interface development
We integrate wallets (MetaMask, WalletConnect) and build UI with React, Web3.js, and Ethers.js. UX is intuitive and secure.
Third-party services & infrastructure integration
We connect oracles, indexers, nodes, APIs, and analytics. Ensure backups, monitoring, and reliability.
Deployment, testing & support
We test on testnets and mainnets, prepare documentation, and assist with launch, listing, and scaling.

Step 1 Research & technical designи техническое проектирование
You share the idea, business logic, token requirements, and user actions. We define product scope, select the blockchain, design contract types, roles, storage architecture, and authorization logic. Tech stack: Solidity, Vyper, Rust, Ethers, GraphQL, React.
Time to deliver
~ 1-2 days
Step 2 Token & smart contract development
We build core contracts: tokens (ERC-20, ERC-721/1155), DAO, DeFi modules (pools, staking, lending). Configure fees, roles, freezing, whitelisting. Add protection against reentrancy, front-running, and other vulnerabilities.
Time to deliver
~ 2-4 days
Step 3 Web3 integration & UX/UI
Frontend development: wallet connections, transaction signing, contract interactions. Adaptive UX with transaction feedback, activity history, balance checks, session security, and data privacy.
Time to deliver
~ 3-7 days
Step 4 Testing, audit & optimization, аудит и оптимизация
Unit and integration tests, attack simulations, internal or external audits. Gas optimization, limit checks, fault tolerance. Full technical documentation.
Time to deliver
~ 5-15 days
Step 5 Deployment & support
Deployment to mainnet or selected network. CI/CD setup, documentation, user support. Ongoing assistance during launch, feedback collection, and scaling.
