Kizoona Tech · Blockchain & Web3
Blockchain systems,
On-chain code is hard to change once deployed and often handles real value. We build smart contracts, tokens and decentralised applications with that responsibility in mind.
Services
From protocol to interface.
- 01Blockchain DevelopmentLayer 1/2 network architectures, custom consensus protocols, EVM integration, and enterprise distributed ledger solutions.
- 02Cryptocurrency DevelopmentNative digital currency development, proof-of-stake coin economics, algorithmic stability mechanisms, and wallet ecosystems.
- 03Token DevelopmentStandardised token engineering (ERC-20, BEP-20, SPL), vesting contracts, deflationary burn mechanics, and governance voting systems.
- 04Smart Contract DevelopmentTested, gas-optimised Solidity and Rust smart contracts, prepared for independent audit, implementing decentralised financial and business logic.
- 05NFT DevelopmentERC-721A minting infrastructure, dynamic on-chain metadata, generative art pipelines, and decentralised IPFS storage.
- 06DeFi DevelopmentAutomated market makers (AMMs), decentralised lending platforms, staking pools, yield aggregators, and algorithmic liquidity protocols.
- 07Decentralised Application (DApp) DevelopmentEnd-to-end decentralised web applications with seamless Web3 wallet onboarding, sub-second RPC state sync, and responsive UI.
- 08Web3 Wallet DevelopmentNon-custodial mobile wallets, browser extensions, ERC-4337 smart accounts, passkey biometrics, and multi-party computation (MPC).
How we work
Security is a process, not a promise.
- 01
Specify before coding
State variables, roles and permitted transitions are written down and reviewed first.
- 02
Test adversarially
Unit, fuzz and invariant tests in Foundry, plus static analysis, on every contract.
- 03
Prepare for audit
NatSpec, diagrams and threat models so independent auditors can work efficiently.
- 04
Explain every signature
Interfaces show what a transaction will do before a user is asked to sign it.
We provide software engineering services only. We do not provide financial, investment or legal advice, and clients remain responsible for the regulatory status of their digital-asset products.
