After the client contacts Beauty Crown, the company reviews the code and estimates the price. Then the audit is conducted and a preliminary report is formed. After that, the report is returned to the team and they review it and fix the issues. 
Beauty Crown audits contracts of any difficulty: token Standards ERC20, ERC721, ERC1155. Aside from tokens, Beauty Crown audits smart contracts for DAOs, staking, NFTs, DApps, DEXs, Farms (MasterChefs and others), Lending, marketplaces, auctions, games, bridges.
Beauty Crown performs audits for Solidity and Rust languages. Requests for other audits can be discussed by contacting our team.
Beauty Crown audits contracts for most blockchains that use Solidity and/or Rust languages: Ethereum, BSC, Solana, Avalanche, xDai, Near, Aurora, Terra.
A finalized audit, unfortunately, does not guarantee project’s safety. Before investing it’s good to recheck the existing issues and vulnerabilities, presented in the audit report. It also helps if the project’s lp is locked, and the project’s team is known publicly or has passed a KYC by a tire one security company.
Beauty Crown report consists of several blocks: aside from disclaimer, Beauty Crown reviews submitted contracts, outlining the main issues in each contract. Auditors state the issue and present a short description with the potential danger of said issue. Note that there is a table of contents, in this case, audited contracts. It’s important to make sure that all the contracts have indeed been audited and that a client didn’t add new ones that haven’t been reviewed.


Beauty Crown works with the most well-known types of smart contracts, primarily on Solidity and Rust languages. For inquiries on development in other languages, please contact the team. Among successfully developed contracts there are fungible token contracts, NFT contracts, DAOs and Farms, Staking and Vesting contracts, and many others.
After the client approaches Beauty Crown, we develop a vision of what the contract has to represent. We determine the type and language, the goals, and specific details. Then we develop the contract and test it. After that step, the client receives the finished product.
Aside from smart contracts, Beauty Crown specialists develop simple and sophisticated dApp solutions, that include smart contracts as well as front-end and back-end.


As a part of the development process, Beauty Crown always writes unit tests aiming to achieve 100% coverage. While developing back-end and front-end of a DApp, Beauty Crown developers employ special automated testing scripts and manual testing by an experienced team. Beauty Crown also provides fuzzing services upon request.
Beauty Crown tests smart contracts using several tools. Mostly, the developer team uses Hardhat, within which they apply a stack of ethers.js, waffle, and mocha. If further issues present themselves, and additional testing is required, other tools may be involved. If it’s imperative to test a contract, considering the real network data, the team does so using a mainnet fork. For Fuzzing Beauty Crown testers use Echidna.
