Custom smart contract development in Solidity, Rust, CosmWasm, and other blockchain languages with security best practices built in. hack provides comprehensive smart contract development services across multiple blockchain platforms including EVM, Cosmos, and Solana.

What We Build

Smart contracts are self-executing pieces of code that live on blockchain networks, automating agreement enforcement without intermediaries. They contain predetermined rules and terms, distributed across blockchain networks, automatically executing when specific conditions are met.

• Multi-language expertise: Development in Solidity (Ethereum/EVM), Rust (Solana, Polkadot), CosmWasm (Cosmos ecosystem), and other languages
• Token standards: ERC-20, ERC-721, ERC-1155, and custom token implementations
• DeFi protocols: Complex cross-chain DeFi protocols and governance systems
• Security-first: Every line written with security best practices, thorough testing, and audit-grade code quality
• Production-ready: 120+ smart contracts deployed to mainnet across multiple chains
• Oracle integration: Expert integration of Chainlink oracles, CCIP, price feeds, data streams, VRF, automation, and custom external adapters

Technical Capabilities
