Aquarius (AQUA) is a decentralised liquidity management protocol built on the Stellar blockchain. Its primary aim is to enhance liquidity across markets within the Stellar ecosystem. Aquarius achieves this by providing incentives for market makers and liquidity providers, both on Stellar's decentralised exchange (SDEX) and through Automated Market Makers (AMMs). The AQUA token is integral to the platform, being used for governance and rewards. Users of the platform can vote on where liquidity should be directed to make Stellar markets more efficient.

Aquarius serves multiple functions within the Stellar ecosystem. It helps increase liquidity on Stellar-based markets by incentivising both market makers and AMM liquidity providers. The AQUA token plays a crucial role in this system, allowing users to participate in governance by voting on decisions such as which markets should receive additional liquidity. Furthermore, AQUA is used to reward participants in market-making activities, as well as voters who engage in governance processes. This makes AQUA a key tool in managing and distributing liquidity within the Stellar network.
