CryptoBottle is a unique concept where an NFT representation of virtual vine is minted, which contains a diverse mix of cryptocurrency assets. The NFT can be "opened" in the future to unlock the underlying assets, and this is permanent and irreversible, decreasing the remaining bottles in the collection. On October 1st, the project experienced thait first exploit for $6k, which happened due to a missing access control on the smart contract's withdrawUseRLiquidity function. This vulnerability or event doesn't appear to be publicly acknowledged by the team and is not widely known. It would be featured in an analysis by CertiK a month later, only after more vulnerabilities had been exploited for much larger losses.[1][2][3][4][5]
About Cryptobottle
"Create, buy or sell first bottles virtual wine. Collect, invest or become an artist by creating your own NFT cryptobottle. Anyone can launch their own vintages (collections) with the possibility of adding benefits that will be used in real life!"
"Cryptobottle is an innovative project designed to empower various entities—such as businesses, associations, event companies, and retailers—to create unique NFT collections. These NFTs, known as "cryptobottles," combine art, utilities, and cryptocurrencies, encapsulating significant financial value. Cryptobottles serve as a versatile tool for promotion, customer loyalty, and sales enhancement."

"These vintages of bottles are actually collections of digital objects which do not contain wine, but cryptocurrencies."
"Each bottle owned gives you access to customer benefits.
The estates offer you these advantages to enhance their wines.
They can take the form of promotional codes, vouchers, loyalty programs, etc cultural advantages.. and are proposed by the domain that creates the vintage.
Other "affiliation" partnerships can also be offered by any company.
The possibilities are endless. Choose your Cryptobottles well!"
