Tubal Cain Masonic Apron NFT

Tubal Cain Masonic Aprons, is a collection of digital designs of 1,000 unique Masonic aprons that will be created as NFTs on the Ethereum network.

Their uniqueness is to be guaranteed by the public blockchain. It is anticipated that it will take 100 weeks to complete the full issuance of the whole collection.

The Tubal Cain Masonic Apron NFTs can be bought and then re-sold at any time. The token owner would have access to the high resolution image file, and will be free to print a copy on paper, or canvas and display a physical copy on their wall. 

A pre-set number of Tubal Cain Masonic Apron NFTs will be gifted to Masonic charity events around the world, to be auctioned at the event to raise charity funds.

The winner of the auction will make their charitable contribution direct with the charity at the event, and then receive the Tubal Cain Masonic Apron NFT, which they can hold or re-sell.

Unique Design

All 1000 Tubal Cain Masonic Aprons will be a unique design.

The aprons are design not necessarily to be exact replicas of real aprons used in lodges, but designer aprons, with an artistic and symbolic design.

The construction of each apron is made up from a specific set of parameters, and each parameter has various options. 

Some options will be used less than others making these aprons more rare than others.

Some aprons might use an option only once, making it a super rare or ultra rare apron.

Pricing Schedule

The pricing schedule will increase due to scarcity.  The first 100 Aprons will start at Etherum  0.05 ( this is approximately $100 at the time of writing ). 

After the first 100 aprons are sold, there will only be 900 left, so they become more scarce, so the value increases. 

Also a low introduction price will reward early adaptors with a greater return on their investment.
