Web Application
The Portal serves as the primary decentralized application (dApp) and financial gateway for the TUSDT system. Deployed on Ink, the native EVM layer of the Bittensor ecosystem the Portal provides users with a seamless interface to manage the full lifecycle of their stablecoin positions.
The application enables users to interact directly with the protocol’s smart contracts through the following features:
Vault Management: Create and manage individualized vaults to oversee debt-to-collateral ratios.
Collateral Operations: Securely add TAO to a vault to increase backing or release TAO once debts are settled.
Token Lifecycle: Execute the minting of TUSDT against deposited TAO or burn TUSDT to reduce outstanding debt.
Auction Participation: Participate in liquidation auctions where users can bid on collateral from undercollateralized vaults.
By leveraging Ink’s infrastructure, the Portal ensures that the TUSDT financial layer remains deeply integrated with Bittensor's native liquidity and security.
Portal Side Description:
The following screenshots illustrate the vault management functionalities of the Portal Side, including vault creation, adding TAO collateral, minting TUSDT, burning TUSDT, releasing collateral and participating in auctions.
The key components responsible for these operations are Vault Creation, Mint TUSDT, Burn TUSDT, and the Auction mechanism, which allow users to manage their collateralized positions and participate in liquidation events within the protocol.
1. Creating Vault
This process is initiated by selecting the “Create Vault” option in the interface, allowing users to open a vault where they can deposit TAO as collateral and mint TUSDT stablecoins.
1. Vault overview
Vault Overview displays the current status of a user’s vault, including TAO collateral deposited, TUSDT minted, and the collateralization ratio. It also provides options to add collateral, mint TUSDT, burn TUSDT, and release collateral.
3. Minting TUSDT
Minting TUSDT is initiated by selecting the “Mint” button in the Vault Overview. This allows users to mint TUSDT stablecoins against the TAO collateral deposited in their vault.
4. Burning TUSDT
Burning TUSDT is initiated by selecting the “Burn” button in the Vault Overview. This allows users to repay their minted TUSDT, reducing the vault’s debt and enabling the release of locked TAO collateral.
5. Adding Collateral
Adding Collateral is initiated by selecting the “Add Collateral” button in the Vault Overview. This allows users to deposit additional TAO into their vault to increase collateral and maintain or improve the vault’s collateralization ratio.
6. Release Collateral
Release Collateral is initiated by selecting the “Withdraw” button in the Vault Overview. This allows users to release TAO collateral from their vault, provided the remaining collateral maintains a safe collateralization ratio.
7. Auction
The platform also includes an Auction mechanism used during the liquidation of undercollateralized vaults. When a vault falls below the required collateralization ratio, its collateral may be placed in an auction.
8. Bid
Users can participate by placing bids starting from the minimum bid amount defined by the protocol. The highest bidder at the end of the auction receives the corresponding collateral. This process helps maintain the stability and solvency of the TUSDT system by resolving undercollateralized positions in a decentralized manner.
Security Features
The Portal Side's Vault Manager and TUSDT Token contracts incorporate critical security features:
Pausable and Upgradeable Proxies Smart Contract: The TUSDT Token Contract uses these patterns for enhanced security and future-proofing.
Circuit Breakers: The Vault Manager includes emergency mechanisms that can halt minting or other critical operations during extreme events, such as a full shutdown if TAO price drops by 18%.
