It's a collection that will give holders access to different conscious workshops such as yoga, meditation, breathwork, sound healing, etc. Would like to have you create a base character for the collection and assist with developing traits/accessories/attributes.

    We are a new DeFi yield optimizer protocol and we're looking to get a smart contract audit before we launch our product! The contracts are mostly a fork of vault/strategy (previously audited by certik and others). Our contracts receive funds from users, issue vault IOU tokens, stake funds and then bond them when optimal (again, most of this is a fork of ). You can see the strategy contract posted here: and our vault contract posted here: We're interested to hear what you think an estimated timeline/price would be for this audit (especially since it's a fork of beefy already).

    Looking to hire a dev for a smart contract, along with whitelist presales and public minting. Interested in both website and smart contract. Would require experienced solidity coding and have made previous erc721 smart contracts and metadata integration. NFT collection will contain no more than 5,000 NFT's. Website would need Metamask integration and the NFT's would need to be minted on OpenSea. The total number is still undecided, it's only known that 5,000 will be our max number of generated images. Project is still 40-45days away from launch. Thanks for your time.
