Each painting from the limited series has its own unique number and NFT-token (the digital analogue of the painting is built on the principle of cryptocurrency) and is created on the SOLANA blockchain. This makes it possible to display work in the digital space while preserving the physical value. It also guarantees the authenticity of the work in both physical and digital space and preservation of copyright.
To receive a token, you must have an electronic wallet that supports the SOLANA ecosystem (such as Phantom, Trust Wallet, Ledger or others)
