ADX Coins usually refer to the AdEx (ADX) project, a decentralized protocol focused on digital advertising. It leverages blockchain technology to offer a transparent and efficient advertising platform. The ADX cryptocurrency is used as a means of payment and incentive within this ecosystem.

The project's main goals include:

1. Transparency: Providing accurate information for advertisers and publishers regarding ad performance.

2. Cost Reduction: By eliminating traditional intermediaries in the advertising world.

3. Privacy Protection: Thanks to the decentralized nature of blockchain, which safeguards user data.

AdEx was launched in 2017 as a platform built on the Ethereum network, relying on smart contracts to ensure transactions are carried out automatically without the need for a third party.
