Leni Smoragdova is a multimedia artist and the creator of the Transaction Art Universe. Using a wide range of forms and mediums, she transforms the transaction—a basic unit of socio-economic exchange and control—into an artistic medium and a protocol for collective action. 

Her practice is developed under the collective identity {Transaction} in collaboration with anonymous participants (Hidden Faces), rendering authorship intentionally unstable and difficult to verify. 

Born in Smolensk in 1984, she currently lives and works in Tbilisi.
