This project used soulbound tokens to "graffiti" the wallets of 23 Ethereum Argentina attendees to commemorate the conference and promote their NFT collection 23 dias sin lavarme available on Opensea.
Soulbound tokens were chosen because like graffiti / street art they have not monetary value because they cannot be bought or sold. They can only be removed / destroyed.
No Me Baño is a street art collective based in Buenos Aires. Links:
This project uses hardhat-deploy
to deploy the contract, upload metadata, and mint tokens.
