Smart Contract Development
Expertise
• EVM-Compatible: Ethereum, BSC, Polygon, Arbitrum, Optimism, Avalanche
• Non-EVM: Solana, Near Protocol, Cardano, Algorand
• Layer 2 Solutions: Polygon, Arbitrum, Optimism, zkSync
• Enterprise Blockchains: Hyperledger Fabric, Corda
Our team recommends the optimal platform based on your project requirements, transaction volume, and budget considerations.
• Following OpenZeppelin security standards and best practices
• Extensive unit testing with 100% code coverage
• Integration and stress testing on testnets
• Static analysis using Slither and Mythril
• Formal verification for critical contracts
• Internal security audits before deployment
• Third-party audit coordination when required
• Post-deployment monitoring and incident response planning
• Complexity: Simple ERC-20 tokens vs complex DeFi protocols
• Features: Number of functions and integration requirements
• Security Level: Standard testing vs formal verification
• Platform: Ethereum mainnet vs Layer 2 solutions
• Audit Requirements: Internal vs third-party audits
Simple contracts start from $5,000, while complex DeFi protocols can range from $50,000 to $200,000+. We provide detailed quotes after requirement analysis.
• Simple Token Contract: 1-2 weeks
• NFT Collection: 2-3 weeks
• Basic DeFi Protocol: 4-6 weeks
• Complex DEX/AMM: 8-12 weeks
• Full DeFi Ecosystem: 3-6 months
This includes development, testing, internal audit, and testnet deployment. Additional time may be needed for third-party audits.
