Smart contract development ranges in cost from $5,000 to $100,000 depending on the complexity of programming and deploying the contract. To get started, smart contract developers should define the contract requirements, create the code, test the contract, and deploy it. These steps may sound simple, but smart contracts must consider all rules to ensure a digital transaction works as planned.

Smart contract development is a required skill for any blockchain developer you work with. When hiring a blockchain development company, ask about its experience creating smart contracts and its approach.
