Smart Contract Development

Secure-by-Design Smart Contract Development

Zealynx builds secure, efficient, and scalable smart contracts for Ethereum/EVM-compatible blockchains and Solana, backed by the same security expertise that powers their audit practice. Every contract is optimized for gas efficiency and upgradeability.

What They Build

• DeFi Protocols: AMMs, lending/borrowing protocols, yield farming, flash loan integrations, liquidity mining rewards
• Token Contracts: ERC-20, ERC-721, ERC-1155, custom tokenomics, governance tokens, deflationary mechanisms
• NFT Projects: Generative collections, marketplaces, royalty mechanisms, dynamic metadata, gaming integrations
• DAO Governance: Voting contracts, proposal systems, timelock mechanisms, treasury management, multi-sig integration
• Staking Systems: Staking pools, reward calculations, slashing mechanisms, delegation systems
• Cross-Chain Solutions: Token bridges, cross-chain messaging, multi-chain deployments, Layer 2 integrations

Development Process

1. Requirements analysis — deep dive into business requirements, tokenomics, and technical specifications
2. Architecture design — scalable and secure smart contract architecture
3. Development and testing — unit tests, integration tests, and fuzzing (Foundry)
4. Audit and deployment — internal security review, gas optimization, and guided mainnet deployment

Notable Projects

• Side.xyz Rewards Protocol: 8+ smart contracts with dynamic APR calculation, performance-based rewards, token vesting, and multi-token support
• Inverter Network Payment & Oracle: 16+ smart contracts with multi-chain price feeds, cross-chain payments, FIFO payment queue, and blacklist system
• Mangrove Hedging Strategy: 5+ contracts extending Kandel market-making with automated hedging via Morpho protocol integration

Engagements available on project-based or ongoing retainer basis.
