Akropolis (AKRO) is a decentralized finance protocol that operates on the Ethereum blockchain. It aims to provide an autonomous financial ecosystem for wealth growth and preservation, including through lending and borrowing. The protocol offers a suite of products, including AkropolisOS, a framework for developing for-profit decentralized autonomous organizations, Sparta, a platform for uncollateralized lending, and Delphi, a yield farming aggregator and tool for dollar-cost averaging. The AKRO token, an ERC-20 token, is used for protocol governance across these products.

Akropolis operates by providing a series of products that aim to facilitate wealth growth and preservation. AkropolisOS, a Solidity-based, modular framework, allows for the creation and management of distributed capital pools. This serves as the foundation for the Sparta and Delphi platforms. Sparta provides access to uncollateralized loans, while Delphi acts as a yield farming aggregator and tool for dollar-cost averaging. Akropolis aims to reduce the risk associated with uncollateralized loans by offering community incentives in the form of AKRO tokens to those who provide accurate risk assessments.

Akropolis was initially conceived as a distributed savings and pensions fund, aiming to address the potential collapse of state pensions systems. However, it has since shifted its focus to building the underlying framework for such a system through AkropolisOS. This allows for the rapid launch of for-profit capital pools. The Sparta platform, part of the Akropolis suite, provides access to uncollateralized loans, while Delphi offers yield farming and dollar-cost averaging tools. These products strive to provide an ecosystem for wealth growth and preservation in the decentralized finance space.

Akropolis was founded in 2017 by Ana Andrianova, who has a background in investment management and private equity advisory. The project was first announced in March 2018 and launched on the Ethereum mainnet in June 2020. Akropolis has a fixed maximum supply of 4 billion AKRO tokens, which were initially distributed through two private token presales in 2018. The AKRO token was publicly listed in July 2019. The Akropolis suite of products utilizes the AKRO token in its protocol, with transactions validated through the Ethereum blockchain's proof-of-work consensus algorithm. The smart contracts for AKRO underwent an audit by blockchain security firm CertiK in August 2019.
