Tool Overview
Smart contract development cost ranges from $8,000 for a simple ERC-20 token to $380,000+ for a full DeFi protocol suite. Here is the complete breakdown by project type.
Key Result
Smart contract development costs: Simple ERC-20 token ($10,000–$22,000 total), ERC-721 NFT ($12,000–$26,000), ERC-20 staking/yield ($40,000–$80,000), AMM DEX ($100,000–$180,000), Lending protocol ($130,000–$240,000), Full DeFi protocol ($280,000–$480,000). Enterprise chaincode: Supply chain traceability ($70,000–$140,000), DSCSA compliance ($110,000–$200,000). Security token: ERC-3643 T-REX ($65,000–$130,000). Cost drivers: novel architecture (+30-50%), multiple chain deployment (+$5K-$15K per chain), formal verification (+$30K-$100K).
