I will build solidity smart contracts with openzeppelin

I develop custom EVM smart contracts using Solidity and OpenZeppelin Contracts 5.x for Ethereum, BNB Smart Chain, Polygon, Base, Arbitrum, Optimism and other EVM-compatible networks.

I can build:

ERC-20 token contracts

ERC-721 and ERC-1155 NFT contracts

Mint, burn and pause functionality

Ownable and role-based access control

Whitelist systems

Vesting and token locking

Staking contracts

Presale contracts

Payment and escrow logic

Custom Solidity smart contracts

Testnet and mainnet deployment support

Contract verification on supported block explorers

You will receive clean and structured Solidity source code based on the requirements of your project.

For complex DeFi, upgradeable, staking or custom tokenomics projects, please contact me before ordering so I can review the scope and recommend the correct package.

Important: testing and code review are included according to the selected package, but this service is not a substitute for an independent professional security audit for high-value production contracts.
