Aura Network: Pioneering Mass Adoption in Emerging Markets

Aura Network is committed to spearheading the mass adoption of Web3 in Emerging Markets, with a strong emphasis on account abstraction for real-life applications. This commitment to enhance user experience with Aura’s Smart Account, an introduction of account abstraction to Cosmos which streamlines user interactions with blockchain technology. This approach not only makes Aura Network more accessible to a wider audience but also enhances its user-friendliness, especially within the Cosmos ecosystem. Supported by its modular architecture that utilizes the flexibility of the Cosmos SDK and the smart contract capabilities of CosmWasm. Aura Network ensures interoperability across different chains. Additionally, Aura sets itself apart by focusing on the practical use of NFTs beyond mere digital collectibles, aiming to integrate them into everyday scenarios, thereby broadening their appeal and utility.

Aura's successful track record is evident, as it was recognized as the second most active Layer 1 network within the Cosmos ecosystem during the bear market in June 2023. Through these deliberate design choices and strategic focuses, including the advancement of NFTs in practical use cases, Aura Network is not just building a blockchain platform; it's fostering a sustainable, user-centric Web3 environment poised for adoption in emerging markets.

Aura and Band Oracle: Ensuring Reliability through CW-Band

Band Oracle is an essential technology piece to help Aura Network achieve its goals. Aura leverages CW-Band to establish a connection with Band Protocol, a decentralized oracle network, to retrieve reliable and secure price feeds from various blockchain ecosystems and real-world data sources.


CW-Band Integration on Aura Network: Flow Chart

CW-Band serves as a vital communication channel, bridging Aura smart contracts with Band oracles. This integration solves Web3’s critical challenge: obtaining trustworthy price data for DeFi applications, specifically in the Cosmos ecosystem. Band Protocol distinguishes itself as one of the few Oracle solutions that can seamlessly integrate with Cosmos, IBC (Inter-Blockchain Communication), and CosmWasm (a WebAssembly virtual machine for smart contracts on Cosmos-based blockchains), thus complementing Aura's technological infrastructure. With the help of our CW-Band, DeFi applications in the Cosmos ecosystem can now access secure and reliable price data more easily than ever.

Benefits of CW-Band for Aura on Aura Network

By utilizing CW-Band, Aura Network leverages the following advantages:

  • Effortless Price Feed Integration: Developers can seamlessly integrate price feeds into their smart contracts through CW-Band, eliminating complex data retrieval processes.
  • Empowering DeFi Applications: Band Oracle’s integration primarily benefits DeFi protocols built on the Aura network where reliable price feeds are essential for DeFi applications to function properly.
  • Enhanced Security through Oracle Optionality: The availability of multiple Oracle services, including Band Protocol, offers developers a variety of oracles to choose from and the capability to aggregate data from different sources. This approach enhances the security of DeFi contracts on Aura.
  • Economic Efficiency: CW-Band is a pull-based data relaying model, meaning that the destination chains can request data already available on the CosmWasm contract. This makes it ideal for Aura to optimize the overhead cost due to the on-demand data approach.

CW-Band facilitates a secure and efficient link between Aura and Band Protocol, ensuring access to trustworthy price data for DeFi applications on the Aura network. This fosters a robust development environment for DeFi protocols, emphasizing security through a diversified Oracle approach.

Building on Aura Network!

Are you interested in building on Aura Network with CW-Band? Here are the essential resources and information you might need to start your developing journey with Aura Network.

  • Aura network is a proof-of-stake (PoS) smart contract chain that implements Cosmos IBC and CosmWasm modules, and the smart contracts are written in Rust through CosmWasm.
  • You can check out Aura Network’s Documentation to learn more about its design and guidelines for deploying smart contracts.
  • Aura uses CW721, CosmWasm's specification for non-fungible tokens (NFTs), which draws inspiration from Ethereum's ERC721 standard. This adaptation enhances the capability of contracts to implement or interact with NFTs on the CosmWasm platform. For a detailed explanation, visit the CW721 spec repository on GitHub.

Integrating CW-Band on Aura Network!

For those interested in integrating Band via CW-Band and who have experience in building dApps on Aura Network and/or other chains within the Cosmos ecosystem, the following resources might be helpful.

Here is an example code showing how to call price feed with CW-Band:

pub fn try_request(
    deps: DepsMut,
    env: Env,
    symbols: Vec<String>,
) -> Result<Response, ContractError> {
    let endpoint = ENDPOINT.load(deps.storage)?;
    let config = BAND_CONFIG.load(deps.storage)?;

    let raw_calldata = Input {
        minimum_sources: config.minimum_sources,
    .map_err(|err| ContractError::CustomError {
        val: err.to_string(),

    let packet = OracleRequestPacketData {
        client_id: config.client_id,
        oracle_script_id: config.oracle_script_id,
        calldata: raw_calldata,
        ask_count: config.ask_count,
        min_count: config.min_count,
        prepare_gas: config.prepare_gas,
        execute_gas: config.execute_gas,
        fee_limit: config.fee_limit,

    Ok(Response::new().add_message(IbcMsg::SendPacket {
        channel_id: endpoint.channel_id,
        data: to_binary(&packet)?,
        timeout: IbcTimeout::with_timestamp(env.block.time.plus_seconds(60)),
