Aqua Protocol is a decentralized finance (DeFi) platform built on the TON blockchain, introducing AquaUSD, an over-collateralized stablecoin backed by liquid-staked assets such as TONcoins. AquaUSD maintains a 1:1 peg to the US dollar through mechanisms like over-collateralization, liquidation protocols, and arbitrage opportunities [[❞]](https://aquaprotocol.xyz/) [[❞]](https://ton.app/utilities/aquaprotocol).
The protocol allows users to deposit TONcoins or Liquid Staking Tokens (LSTs) as collateral to mint AquaUSD. This stablecoin can be utilized across various DeFi activities without needing to sell the underlying assets. Aqua Protocol supports a range of liquid staking tokens from platforms like Bemo, Tonstakers, Hipo, and Ton Whales, ensuring liquidity and stability for its users

One of the unique features of Aqua Protocol is its fee structure. It offers a 0% interest rate on loans, with minimal fees for minting and repaying loans, capped at 0.5%. This makes it an attractive option for those looking to leverage their crypto holdings without incurring significant costs (https://aquaprotocol.xyz/).
Aqua Protocol also integrates with various TON ecosystem projects, providing users with opportunities for yield farming, liquidity provision, and risk hedging. These integrations allow users to enhance their investments and diversify their strategies within the DeFi space without liquidating their holdings
