FAQ
Which chains do you deploy to?
Any EVM compatible chain: Ethereum, BSC, Polygon, Arbitrum, Base, Avalanche, Optimism, and custom or private EVM networks. Tell us your target chain before ordering and we will confirm gas costs and deployment specifics.
Do you audit smart contracts?
We write audit ready code — gas optimised, following current OpenZeppelin patterns, with a full test suite delivered alongside every contract. A formal third party audit is a separate engagement and we can coordinate one on request. We do not sell audits of contracts written by others.
Do I get the source code and ownership?
Yes, on every package. You receive the full Solidity source, the test suite, and deployment scripts, with complete IP ownership. Contracts are verified on the block explorer so anyone can read them.
Can you build the frontend as well as the contract?
Yes. Standard and Premium include a web3 dApp frontend with wallet connection, contract interaction, and transaction status handling. Basic is contract only, for buyers who already have an interface or only need the on chain logic.
Can you create a token for my project?
We build ERC20, ERC721 and ERC1155 contracts to your specification. We do not provide exchange listings, white papers, tokenomics advice, ICO marketing, or anything related to promoting or selling a token. Those are outside our scope.
Who pays for gas and deployment costs?
You do, and they are separate from our fee. Mainnet gas varies with network conditions and the contract's size. We will estimate it before deployment and deploy from your wallet or a wallet you fund.
