Accessing Locked USD on Kardia Chain After Three Years

Three years ago, I converted my $KAI tokens to USD on the Kardia Chain network, and those USD still reside there today. Currently, I see that Kardia Chain has approximately 3,730 wallet holders who hold USD, including myself, with a total combined value of around $351,489. I'm wondering how I can now access my $1,226, and whether this USD still exists on the network. Understanding the mechanics of Kardia Chain's wallet and token redemption process is essential. It's important to verify if the USD is stored as a smart contract or in a custodial wallet, which could affect the ease of withdrawal. Given the time lapse of three years, it is possible that the USD is still stored on the network, but accessibility and transfer procedures may have changed or require specific steps. Reaching out to Kardia Chain support or reviewing official documentation should clarify my options for retrieving the USD. In summary, the USD may still be present on the Kardia Chain network, but I need to confirm the current status and procedures for redemption to ensure I can access my funds now.
