It is designed to maintain a stable value equivalent to the US Dollar (USD) while integrating with the broader Acala ecosystem. Here’s a detailed look at what aUSD is and why it might be of interest:
What is Acala USD Stablecoin (aUSD)?
- Definition: Acala USD (aUSD) is a decentralized stablecoin that aims to provide a stable and secure digital currency pegged to the value of the US Dollar. It is native to the Acala Network, which is a DeFi hub on the Polkadot blockchain.
- Purpose: The primary purpose of aUSD is to serve as a stable medium of exchange and store of value within the Acala ecosystem and beyond. It facilitates various DeFi activities such as lending, borrowing, trading, and liquidity provision.
Key Features of aUSD

- Governance and Stability:
- Decentralized Governance: The Acala Network incorporates decentralized governance mechanisms to manage and adjust the stablecoin system. Token holders and stakeholders can participate in decision-making processes to ensure the stability and evolution of aUSD.
- Algorithmic Adjustments: The system may use algorithmic adjustments to maintain the peg, such as modifying interest rates or adjusting collateral requirements.
- Transparency and Security:
- Audited Contracts: The smart contracts governing aUSD are typically audited to ensure their security and reliability. Transparency is a key aspect, with mechanisms in place to verify the backing and stability of the stablecoin.
