We have now been trained to regularly swab, spit, and give up ownership of our bodily substances to corporations and government run centers. These fluids hold the data of our DNA, personal information, and identity. Can I as an individual human become your saliva deposit center instead? Can we take saliva exchange back into our own hands?

You are invited to exchange a sample of your saliva with one of my own. A Terms Of Exchange outlines my intention to protect the privacy of your identity and biodata. You are free to do as you like with my own saliva.

Along with the physical storage of the saliva sample, a digital representation of each sample is stored on the blockchain as an NFT. The growing collection of saliva is an archive of a moment when our boundaries of our bodies and DNA is shifting.

By purchasing this NFT, the collector is committing to a DNA data exchange. The image of the NFT will be changed by the artist on IPFS with a unique representation based on the collectors personal data.



About Lauren Lee McCarthy

In Lauren Lee McCarthy's artistic practice, social relationships are examined amongst surveillance, automation, and algorithmic living. Fascinated by the ways in which we interact with algorithms and one another, McCarthy contemplates the effects of glitches within social and technological structures.

Exploring ideas of self-awareness and control, McCarthy's performances challenge both visitors and the artist to engage in mutual risk taking. Here, software, electronics, internet, film, photography, and installation combine in scenarios where one can buy a lifetime of goodnight texts, or a real life “follower” for a day.

McCarthy has received grants and residencies from Creative Capital, United States Artists, LACMA, Sundance New Frontier, Eyebeam, Pioneer Works, Autodesk, and Ars Electronica. Her work SOMEONE was awarded the Ars Electronica Golden Nica and the Japan Media Arts Social Impact Award, and her work LAUREN was awarded the IDFA DocLab Award for Immersive Non-Fiction. Lauren's work has been exhibited internationally, at places such as the Barbican Centre, Fotomuseum Winterthur, Haus der Elektronischen Künste, SIGGRAPH, Onassis Cultural Center, IDFA DocLab, Science Gallery Dublin, Seoul Museum of Art, and the Japan Media Arts Festival.

Lauren is also the creator of p5.js, an open-source art and education platform that prioritises access and diversity in learning to code, with over 1.5 million users. She expands on this work in her role on the Board of Directors for the Processing Foundation, whose mission is to serve those who have historically not had access to the fields of technology, code, and art in learning software and visual literacy. Lauren is an Associate Professor at UCLA Design Media Arts. She holds an MFA from UCLA and a BS Computer Science and BS Art and Design from MIT.
