The following describes how this project will implement a fair NFT sale and minting.
- Art will be generated using an art engine similar to this.
- The final generated art will be hashed using CIDs and each art CID will be added to its relative metadata.
- Each art metadata will be hashed using CIDs and the provenance hash will be a sequence of these.
- Before the NFT sale, the art as well as the provenance hash will be posted.
- When the contract is deployed, the code will reserve the first 16 NFTs for the team.
- The sale will begin as described on the
START_DATEspecified inBadBabyBearBotsCollection.sol. Minting merely assigns token IDs to owners. - No art will be revealed (assigned to a token ID) until
withdrawis called, in which the starting image assigned will depend on the last block number recorded.
The following describes how the contracts will prevent any scams and/or rug pulls on our side.
- The
BadBabyBearBotsCollection.solhas the BBBB multisig wallet and the DAO hard coded when deployed. In thewithdrawfunction the funds will be transferred to only these contracts and cannot change (immutable) - The
BBBBMultisigWallet.solwill be the only smart wallet used to disburse funds to suppliers. Requesters and approvers will be assigned at the discretion of BBBB. The wallet will prevent requests more than 20 ETH - The
BBBBDAOFI.solwill be the only smart wallet used to disburse funds to NFT and blockchain projects. Requesters can only be BBBB and approvers can only be NFT holders. The wallet will prevent requests more than 5 ETH
Only 1 request per teir is allowed per respective cooldown. This means it would take at best 10 months to withdraw 465 ETH.

All transactions have metadata with more information about each transaction. It would look like the following. The total of the amount should be equal to the request amount.

Make sure in .env to set the BLOCKCHAIN_NETWORK to hardhat.
