# Challenges

1. **Transition from EVM to Cosmos Blockchain**:
   * One of the major challenges we faced was transitioning from the Ethereum Virtual Machine (EVM) to the Cosmos blockchain. This required intensive research to resolve.
   * Initially, we considered using Axelar, but their API was not functioning properly.
   * We then tried the Squid router; however, the IBC relayer was not processing the payments in a timely manner, making it unsuitable for our needs.
   * Ultimately, we adopted Noble and their Cross-Chain Transfer Protocol (CCTP), which provided a reliable solution.
2. **Fiat Gateway Implementation**:
   * Implementing the fiat gateway presented significant difficulties. Based in India, we faced restrictions that prevented us from directly using a fiat on-ramp.
   * Additionally, lacking a merchant account made it challenging to test the gateway effectively.
3. **Development of AkashPay as a Platform and API**:
   * Creating AkashPay both as a platform and as an API for direct payments required extensive testing and development.
   * Ensuring the platform's robustness and reliability was a time-consuming and complex process.
4. **Akash Network Testnet and Relayer Issues**:
   * We encountered issues with the Akash Network testnet, which was not operational during our development phase.
   * Furthermore, the relayer responsible for converting AKT(osmosis) to AKT(Akash network) was also not functioning. As a result, we had to keep the converted tokens on the USDC (Osmosis) network.
