Lista USD (lisUSD) is a decentralized, collateral-backed stablecoin, referred to by its creators as a "destablecoin," soft-pegged to the US Dollar. It operates as a BEP-20 token on the BNB Chain and Ethereum. The stablecoin is generated through the Lista DAO protocol, where users can take out a loan in lisUSD by depositing various crypto assets as collateral. The stability and backing of lisUSD are maintained through an over-collateralized lending model and a series of algorithmic peg-stability mechanisms. ^{[1] [2]}​

Overview

Lista USD is an integral component of the Lista DAO ecosystem, a platform for liquid staking and decentralized lending. The protocol defines lisUSD as a "destablecoin," an asset class characterized by being over-collateralized with crypto assets, including liquid staking tokens, and being redeemable for $1 worth of the underlying collateral. This model differentiates it from fiat-backed stablecoins, which rely on reserves held by a central custodian, and purely algorithmic stablecoins, which often lack tangible backing. ^{[1] [3]}​

The creation of lisUSD is permissionless; users generate it by depositing accepted collateral into a smart contract vault known as a CeVault and then borrowing lisUSD against the value of their collateral. This process creates a Collateralized Debt Position (CDP). The total supply of lisUSD is dynamic, increasing as users take out new loans and decreasing as existing loans are repaid and the corresponding lisUSD is burned. The protocol is designed to be non-custodial, with user funds managed by smart contracts rather than a central entity. ^{[2] [3]}​

The project was initially launched as Helio Protocol, with its native stablecoin named HAY. Following a strategic rebranding to better reflect an expanded vision that included liquid staking, the protocol became Lista DAO, and HAY was renamed to lisUSD. Lista DAO has received investment from Binance Labs, the venture capital and incubation arm of Binance. ^{[1] [3]}​

History

The origins of Lista USD trace back to Helio Protocol, an open-source liquidity protocol on the BNB Chain. Under this name, the project's native stablecoin was HAY. The protocol underwent a security audit by Certik in May 2022 and a security review by Defi Safety in August 2022. ^[1]​

During its time as HAY, the stablecoin experienced significant price volatility. On August 25, 2022, its price reached an all-time high of approximately 1.46 on August 24, 2022. ^[4] The protocol navigated challenging market conditions throughout 2022, including the market-wide instability following the collapse of the Terra ecosystem. On December 2, 2022, the stablecoin faced a severe de-pegging event, with its price falling to an all-time low of approximately $0.21. This event highlighted the stability risks associated with crypto-backed stablecoins during periods of extreme market stress. ^{[1] [4]}​

Following these events, Helio Protocol announced a rebranding to Lista DAO. This transition was part of a broader product update to better reflect the project's expanded mission, which combined the stablecoin protocol with liquid staking services. Consequently, the HAY token was renamed to lisUSD. The migration from the old community channels, such as the helio_money Telegram group, to new ones under the Lista DAO name marked this new phase. ^{[5] [1]}​

Mechanics and Technology

The functionality of lisUSD is based on established decentralized finance principles, primarily the Collateralized Debt Position (CDP) model, with a system design initially based on the MakerDAO model for BNB Chain and the Liquity model for Ethereum. ^[3]​

Collateralized Debt Position (CDP) Model

The generation and lifecycle of lisUSD follow a clear process:

1. Deposit Collateral: A user deposits approved crypto assets into a smart contract known as a CeVault. These vaults serve as the collateral pools for the protocol.
2. Borrow (Mint) lisUSD: After depositing collateral, the user can borrow (mint) a certain amount of lisUSD against their position. This action creates a CDP, which represents the user's debt to the protocol. The amount of lisUSD that can be borrowed is limited by the collateral's value and a predetermined Loan-to-Value (LTV) ratio.
3. Repay and Withdraw: To reclaim their collateral, the user must repay the principal lisUSD debt plus any accrued borrowing interest or stability fees. Upon repayment, the corresponding lisUSD is burned, removing it from circulation. ^[2]

Collateralization and Supported Assets

lisUSD is an over-collateralized stablecoin, meaning the total value of assets locked in the CeVaults must be higher than the total value of the outstanding lisUSD debt. This provides a buffer to absorb price volatility in the collateral assets. The protocol enforces a Minimum Collateral Ratio (MCR) that each CDP must maintain. On the BNB Chain, the MCR for major assets like BNB, ETH, slisBNB, and wBETH is 150%, which corresponds to a maximum Loan-to-Value (LTV) ratio of approximately 66%. On Ethereum, the protocol's design allows for a lower MCR of 110% for ETH collateral. ^{[3] [4]}​

As of late 2025, the Lista protocol accepts a wide range of assets as collateral on the BNB Chain, including:

• Native Tokens: BNB, ETH
• Liquid Staking Tokens (LSTs): slisBNB, wBETH, wstETH, STONE
• Bitcoin-Pegged Tokens: BTCB, solvBTC, pumpBTC, mBTC
• Stablecoins: USDT, FDUSD
• Other Tokens: mCAKE, mwBETH

A minimum loan of 15 lisUSD is required. Borrowing interest rates are variable; for instance, loans against BNB and ETH have 0% APY, while loans against LSTs like slisBNB incur a 1.5% APY. ^[3]​

Supported Blockchains and Contract

lisUSD operates primarily on the BNB Chain as a BEP-20 token. The protocol has also expanded to the Ethereum blockchain. The BNB Chain token contract is a Transparent Upgradeable Proxy, which allows the contract logic to be updated without requiring a token migration. ^[6]​

Peg Stability Mechanisms

The protocol employs a multi-faceted strategy to maintain lisUSD's soft peg to the US Dollar, combining reactive and proactive measures.

Liquidation Process

Over-collateralization is the first line of defense. If a borrower's collateral ratio drops below the MCR due to a decline in the collateral's market price, their CDP becomes subject to liquidation. In this process, the protocol seizes and sells the collateral to repay the lisUSD debt and a liquidation penalty. This mechanism removes under-collateralized debt from the system, ensuring the solvency of the remaining circulating lisUSD. ^[2]​

Stable Pool - Price Stability Module (PSM)

The PSM is a key peg-enforcement tool that allows users to swap lisUSD for other approved, highly liquid stablecoins (like USDT or USDC) at a 1:1 ratio with low fees. This creates a powerful arbitrage opportunity.

• **If lisUSD > 1 of another stablecoin for 1 lisUSD, then sell the lisUSD on the open market for a profit, creating downward price pressure.
• **If lisUSD < 1 worth of another stablecoin in the PSM, creating upward price pressure. ^[2]

lisUSD Saving Rate (LSR)

The LSR is a variable yield that users can earn by depositing their lisUSD into a dedicated savings contract within the protocol. Lista DAO's governance can adjust this rate to act as a monetary policy lever. By increasing the LSR, the protocol can increase the demand for lisUSD, as users buy it to earn the higher yield. This helps push the price back up toward the peg. Conversely, decreasing the rate can reduce demand if the price is trading above the peg. ^[2]​

Advanced Mechanisms

Lista also utilizes more advanced strategies for stability and capital efficiency:

• Direct Deposit Module (D3M): Allows the protocol to mint and deposit lisUSD directly into external, trusted lending markets to earn yield, increasing the protocol's revenue and utility.
• Algorithmic Market Operations (AMO): A framework that allows the protocol itself to perform operations to support the peg, such as deploying its own collateral or minting lisUSD to provide liquidity on decentralized exchanges. ^[2]

Tokenomics and Market Data

Lista USD (lisUSD) functions as a decentralized, crypto-collateralized asset issued on the BNB Chain. It is structured as a BEP-20 token and is designed to maintain its function within the protocol’s broader stablecoin framework, with issuance and management tied to collateral mechanisms established by the platform. ^{[3] [5] [4]}

Use Cases

• Borrowing: Users can access liquidity in the form of a stable asset (lisUSD) without selling their crypto holdings.
• Yield Generation: lisUSD can be staked on the Lista platform or used to provide liquidity in pools on decentralized exchanges such as PancakeSwap, Wombat Exchange, and ThenaFi to earn trading fees and other incentives.
• Trading and Hedging: As a stablecoin, it can be used as a medium of exchange and a tool to hedge against the price volatility of other cryptocurrencies.
• Payments: lisUSD can serve as a means of payment for goods and services within the crypto economy. ^[3]
