METAWALLS is the new NFT platform inspired by, and built for Berlin?s artists. METAWALLS is bringing Berlin?s vibrant Street Art culture into the Metaverse and the world of blockchain. METAWALLS CO-NFT concept allows 'fractional' distribution and ownership of a single NFT artwork; using the METAWALLS custom APP, an original artwork can be minted as 'fractionalised' shares. The APP has been developed in-house to enable participating artists to monetise and share their work. Shares can be collected, traded, or blended (to generate unique NFT's) and are governed by a customised OpenZeppelin ERC-1155 Smart Contract, providing secure, lifelong proof of ownership on the Polygon POS blockchain.
