Hi everyone,

I'm planning a decentralized app (dApp) project and intend to use OpenZeppelin libraries for smart contract development. Could anyone share advice or methods on how to accurately estimate the cost involved, including development, security audits, and deployment? Any tips or best practices would be greatly appreciated.

Thanks a lot!

For the cost to deploy, maybe you can use hardhat-gas-reporter.
As for audit, it depends on your contract and the audit team.

To estimate the cost of developing secure smart contracts using OpenZeppelin libraries, consider the following factors:

  1. Development: Factor in the complexity of your dApp, the number of smart contracts, and features like ERC-20 tokens, proxies, and upgradeable contracts. Developer hourly rates vary, but typically range from $50 to $150/hour.

  2. Security Audits: A professional audit costs anywhere from $5,000 to $20,000, depending on the contract's complexity.

  3. Deployment: Gas fees for deployment can fluctuate based on network congestion, but expect to spend $100 to $500 per contract.

Factor in time for testing, debugging, and future maintenance as well.
