STBL (@stbl_official): Contract Updates & Next steps

Contract Updates & Next steps We are pleased to announce that USST contract creation and deployment is complete and the protocol is now undergoing a full audit with Cyfrin. With this milestone set, we are moving swiftly toward scaling liquidity and expanding strategic partnerships. USST Contract Details and Coverage The USST contracts implement several critical features that support the Tri-Factor and the overall stability architecture: Collateral and Over-collateralization: USST is over-collateralized by high-quality Real-World Assets (RWAs), including USDY, USDG, BUIDL, OUSG, and BENJI. The contracts ensure that the yield earned on this collateral remains in the minted NFT, YLD. Segregated Structure: The contracts are designed with a Segregated Vault structure. Financial Parameters: Key parameters are established, including the Haircut (a margin on collateral value that ensures USST is over-collateralized and functions as a deposit), and the Minting Fee and Withdrawal Fee, both of which are dynamic and variable. Flexible Redemption Implementation: The contracts support flexible burning, allowing for the partial redemption of collateral by the fractional burning of USST. Dynamic Peg Enforcement: Crucially, the contracts implement the automated peg adjustment mechanism by automatically adjusting the dynamic minting and burning fee rates within pre-defined thresholds based on market conditions, maintaining the equilibrium. The updates also included provisions for the transfer of YLD to whitelisted addresses (Convertors). What Constitutes the Tri-Factor Protocol The Tri-Factor Protocol is the foundational stability mechanism for USST, ensuring adequate balance of demand and supply within the ecosystem and facilitating incentivised liquidity provisioning. It consists of three core elements: Dynamic Mint/Burn Rates: This involves the dynamic adjustment of minting and burning rates based on external market factors that drive those rates. Flexible Redemption: The protocol enables partial redemption on YLD to allow minters to withdraw collateral. Converter Liquidity Provision: This entails flexible and par liquidity for USST enabled through specialized ecosystem participants known as Converters. This flexibility also involves the whitelisted transfer of YLD to Converters. How USST's Peg Is Dynamically Managed Using the Tri-Factor The Tri-Factor's primary function is to enable an automated peg stability mechanism through dynamic adjustment of minting and burning rates, which incentivizes or disincentivizes these activities to balance the supply and demand for USST. The objective of the peg mechanism is to incentivize arbitrage to stabilize the value of USST to $1. The Role of Convertors and Arbitrage The system is designed to encourage market participants, especially Convertors to exploit price arbitrage opportunities to revert USST to equilibrium. The peg mechanism is driven by a sophisticated calculation utilizing five key external factors monitored across various venues: the price of USST, the change in supply of USST, the change in liquidity depth, the change in the USST/USDC price over a set duration (default: 1 minute), and the resultant dynamic fees. Convertors are essential high-volume liquidity providers and market makers who are incentivized to use their money market holdings to mint USST and drive arbitrage returns. If USST Drops Below $1 (e.g., $0.995): This situation signals an oversupply of USST. The system immediately increases the Minting Fee (up to a maximum of 10%) to stop new supply from being created. Simultaneously, the Burning Fee is lowered to 0% to encourage removal of existing supply. Convertors are incentivized to buy the cheap USST from the market (at $0.995) and immediately burn it. Since USST is over-collateralized (meaning $1 of USST represents slightly more than $1 of collateral, e.g., $1.001), burning USST unlocks collateral worth more than they paid, creating a profit (arbitrage). This action removes excess USST and pulls the price back toward $1. If USST Rises Above $1 (e.g., $1.01): This signals higher demand than available supply. The system reduces the Minting Fee (down to a minimum of 0.1%) to encourage new supply, while the Burning Fee is increased (up to 5%) to discourage withdrawal of collateral. Convertors are incentivized to mint USST cheaply and sell it immediately on the market at the higher price (e.g., $1.01), capturing an arbitrage profit. This flood of new supply helps stabilize the price back to $1. Next steps The USST team focused on conservatively building optimal infrastructure for USST minting to create a strong foundation before scaling. Contract Deployment Status: The contract features for the Tri-Factor update including the automated peg adjustment mechanism, partial redemption, YLD transfer, and vault segregation have been completed & are under audit. Deployment of tri-factor updated contracts on mainnet and enhanced testing with controlled minting will happen in December 2025 Immediate Next Steps (December 2025): The focus is now on the AMM initiation and controlled scaling of liquidity for DEX pools for USST Early 2026 Expansion: DeFi lending (Phase 1) and Perp DEX denominated USST pairs (Phase 2) are targeted for January 2026. Native minting on other chains (Q1 2026) Future Listing: The listing of USST on a Centralized Exchange (CEX) with USST/USDT and USST/USDC pairs is targeted for Q1 2026
