Development of a smart contract for a new token (Solidity)

Hello!

The Benefit Studio team has experience in developing and auditing smart contracts on Solidity for tokens, DeFi projects, staking mechanisms, and EVM-compatible networks.

We can implement:
• ERC-20 token with custom tokenomics;
• vesting, lock-up, and token distribution mechanisms;
• a full set of tests (Hardhat / Foundry);
• gas cost optimization;
… • deployment to Testnet and Mainnet;
• a basic security review before launch.

In our work, we adhere to OpenZeppelin best practices, paying special attention to security, scalability, and code transparency.

Best regards,
The Benefit Studio Team

we have practical experience in developing tokens and smart contracts for launch - ERC-20, vesting, lock periods, supply distribution, tests, deployment in testnet and mainnet

price guideline - from 45000 UAH and 8-10 working days for a neat basic token with tests and gas optimization
if the tokenomics is more complex - several rounds, cliff, vesting for different groups, whitelist or role management - then it’s better to recalculate the estimate after the conditions

we can keep it simple - we create the contract based on verified libraries, add tests, check typical risks, deploy first in testnet, after your verification - in mainnet
access to private keys is not needed - it’s better to deploy through your wallet or provide you with the deployment script, as security is not a decorative matter =)

Please let us know
… - which network you plan to launch in
- whether mint or burn is needed after launch
- what specific lock periods and distribution among groups

currently available, we can discuss the tokenomics conditions directly within the exchange and provide a more accurate estimate by stages

Hello.

I am a Senior Software Engineer with over 10 years of software development experience, and in recent years, I have been actively working with blockchain solutions and smart contracts on Solidity.

I have experience in developing and auditing ERC-20 smart contracts, contracts for token staking, reward systems, locking mechanisms (vesting/lockup), administrative panels for managing contract parameters, and integration with Web3 services.

What I can implement for your project:

• ERC-20 token according to OpenZeppelin standards
… • Tokenomics logic (distribution, vesting, lock periods, reserves, teams, marketing, etc.)
• A complete set of tests (Hardhat / Foundry)
• Gas cost optimization
• Deployment on Testnet and Mainnet
• Documentation and support during launch

I recently completed the development of a Secure ERC-20 Staking Vault — a smart contract for token staking with a reward system, reward reservation, emergency withdrawal, and protection against common vulnerabilities.

The estimated cost of implementing a similar token with tokenomics, tests, and deployment: from 500 to 1000 USD depending on the complexity of the vesting mechanisms and additional requirements.

I am ready to review the details of the tokenomics and propose an optimal technical solution.

Hello, I have extensive experience in writing contracts in Solidity. If you are interested in truly high-quality development of your contract, please message me to discuss the details quickly and efficiently. I can send you a sample of the contract code that I have written in private messages.

Good day, I have extensive experience in developing smart contracts, I have written a contract for a token with APY payouts, a contract for a game bank of a crypto casino, a token contract with a multi-level referral system, I know how to create code for minimal fees, the cost of your development is $250, I can send code examples in private messages.

Hello! I have experience in Solidity/Foundry and production Web3 development.

I have previously worked on private DeFi/Web3 projects where I wrote Solidity contracts, tests, deploy scripts, worked with ERC-20 approvals, owner-only functions, allowlist mechanics, Base, Arbitrum mainnet/testnet, and backend infrastructure around on-chain logic.

I do not disclose the full code of active projects due to private business logic, but I can show anonymized fragments, test structure, results of `forge test`, and prepare a public demo ERC-20 repository for your task.

For your project, I can implement:

* ERC-20 contract on OpenZeppelin
… * token distribution
* lock/vesting, if needed
* Foundry tests
* gas optimization where it does not compromise security and code readability
* deploy scripts
* deployment to testnet
* deployment to mainnet after verification
* contract verification in explorer
* README with instructions

Before providing an accurate estimate, we need to clarify the tokenomics: total supply, distribution, lock/vesting, whether mint/burn, pause, blacklist/whitelist, transfer tax, or other restrictions are needed.

hello
I will be glad to work with you, ready to discuss everything and, if necessary, show ready smart contracts in personal messages
I have considerable work experience)

I have deep practical experience working with smart contracts on Solidity. A significant part of my previous development relates to creating contracts for the rental sector. This area requires flawless implementation of complex financial conditions, secure asset custody, automatic payment distribution, and time-locks. These skills are critically important for properly setting up tokenomics, coin distribution, and lock-up periods according to the ERC-20 standard.

I am ready to take on the full cycle of creating your token, ensuring its reliability and optimization. I will cover the code with detailed Unit tests (Hardhat/Foundry), check for common attack vectors (Reentrancy, Front-running, etc.) to guarantee the security of funds. I will also apply modern Solidity practices (for example, using custom errors instead of long requires, proper variable packing) and my own optimized algorithms to keep network fees to a minimum.

Hello! Are you planning to use standard tokenomics features like mint and burn, or do you need custom logic with multi-stage locking? I will clarify the deadlines and budget more precisely in personal correspondence.

1. I will write a clean and secure smart contract based on the ERC-20 standard with all your tokenomics requirements.
2. I will implement the coin distribution logic and locking periods, as well as optimize the code to minimize gas costs.
3. I will create a complete set of tests to verify functionality and security, after which I will deploy the contract first on Testnet and then on Mainnet.

Thank you for considering my proposal. I am excited about the possibility of working with you!

Good day.
I constantly write smart contracts for EVM networks. Examples of my work are in my profile.
I am ready to write a contract for an ERC-20 token with a distribution and freezing system. I will write tests for the contract on Foundry. Please send a more detailed technical specification.
