The 'Proof of Passion' collection was published by Socios in cooperation with eight of their Brazilian football fan token partners. Each matchday during the 2024 season, one digital collectible per participating club could be claimed for free on Chiliz Chain via the Gotas platform. Collectors of all 38 collectibles of a team could earn a 39th diamond NFT and access exclusive prizes.

Socios launched matchday NFTs within its 'Socios.com NFT Matchday Series' for several of its Fan Token partners during the 2021-22 season. The displayed NFT celebrates Atlético Mineiro's championship in the 2021 season and was airdropped to fifty lucky GALO Fan Token holders. The NFT contains an image of Atlético Mineiro's players lifting the trophy, the GALO Fan Token ticker on the left side and official Socios and Atlético Mineiro branding at the bottom.
