Blockchain & Cryptography
We engineer secure Web3 solutions, including custom smart contracts, decentralized applications (dApps), and cryptographic systems. We prioritize contract optimization to minimize gas fees and conduct extensive testing to prevent security vulnerabilities. Whether you are integrating wallet connections, issuing tokens, or building decentralized protocols, we write clean, audited code. We construct using high-performance backend development languages and frameworks including Go (Golang), Rust, Python, Node.js, Express.js, NestJS, and FastAPI. We specialize in API development and integration, creating secure, high-throughput RESTful and GraphQL APIs that sync data between frontends and backend services. We ensure all custom software projects deliver high reliability, clean architectural conventions, and detailed documentation. Every engagement includes 2 weeks of post-launch operational support at no extra cost to guarantee that your team is fully onboarded and any minor post-release issues are resolved immediately.

Frequently Asked Questions
Have questions about our blockchain & cryptography service? Find answers to commonly asked questions below.
How do you verify smart contract safety?
We perform rigorous automated testing, gas cost optimizations, and complete code audits to prevent common vulnerabilities (reentrancy, overflow, authentication errors).
What Web3 wallets do your applications support?
We integrate wallet connection libraries like RainbowKit and Web3Modal, supporting MetaMask, Coinbase Wallet, and WalletConnect.
Which blockchain networks do you build on?
We build on Ethereum, Layer 2 networks (Arbitrum, Optimism, Base), and EVM-compatible chains (Polygon, BNB Chain).
What token standards do you support?
We write smart contracts matching ERC-20 (fungible tokens), ERC-721 (NFTs), and ERC-1155 (multi-token standards) guidelines.
How do you compile and test smart contracts locally?
We use frameworks like Hardhat or Foundry to write Solidity tests, simulate gas consumption, and fork mainnet networks.
How do you prevent reentrancy attacks in Solidity code?
We follow the Checks-Effects-Interactions pattern, use OpenZeppelin ReentrancyGuard modifiers, and run static analysis tools.
Can you host decentralized app frontends on IPFS?
Yes, we export static React builds and deploy them to decentralized hosting networks like Fleek or IPFS.
What is included in the 2 weeks of post-launch support?
We track transaction logs on the mainnet block explorer, check smart contract states, and verify RPC node connections at zero cost.
How do you optimize smart contracts to save gas fees?
We optimize variables, avoid redundant storage operations, use packing techniques, and audit execution loops.
Can we build upgradeable smart contracts?
Yes, we implement proxy patterns (like UUPS or Transparent Proxy) using OpenZeppelin standards to allow bug fixes after deployment.
