Alkimi Exchange


Alkimi Exchange (AlEx) is a decentralised ad exchange supporting the buying and selling of digital ads programmatically using a combination of the Ethereum Virtual Machine, Open RTB, and Prebid.

The unique composition of Alkimi’s technology allows AlEx to take advantage of the transparency of the blockchain and cost savings afforded by using a decentralised network of node operators whilst being interoperable with the existing mechanism for purchasing ads online.


AlEx operates on Ethereum; our vertical app allows the buying and selling of programmatic ads. The Ads Explorer records all the validated transactions on the Alkimi distributed ledger.
