StableCoin

USD.AI is a yield-focused synthetic dollar protocol designed for AI infrastructure financing. By integrating stablecoins with GPU-backed lending, it establishes a dual-token structure: USDai as the stability layer and sUSDai as the yield layer. The governance token, CHIP, manages interest rates, risk parameters, and return distribution, facilitating both the financialization and enhanced liquidity of AI physical hash power assets.

Ethena (ENA) is the governance token of the Ethena protocol, supporting sENA staking, ecosystem incentives, and risk governance. This article explains ENA’s utility, allocation structure, incentive model, and its relationship with the USDe ecosystem.

Ethena is a synthetic dollar protocol built on Ethereum. Its core stablecoin, USDe, maintains a stable value through a delta-neutral hedging mechanism. Unlike traditional stablecoins that rely on fiat reserves, Ethena stabilizes value by holding crypto assets while opening offsetting short positions in derivatives markets.

Ethena (ENA) is a decentralized stablecoin protocol that uses derivatives hedging to create a stable asset without relying on traditional fiat reserves. By combining onchain assets with derivatives markets, it aims to produce USDe, a stablecoin that maintains its value through hedging rather than direct backing by fiat. As stablecoins continue to play a growing role in DeFi, Ethena introduces a new model that differs from both fiat-backed and overcollateralized designs.

USD.AI facilitates AI infrastructure financing by leveraging AI hashrate assets, such as GPUs, as collateral and integrating on-chain lending and return distribution mechanisms. When users deposit stablecoins, they can mint USDai, and the underlying funds generate returns through GPU-backed loans, which are distributed to sUSDai holders. This approach converts AI hashrate assets into yield-generating on-chain credit assets, establishing a DeFi credit marketplace dedicated to AI infrastructure.

CHIP serves as the primary governance token of the USD.AI protocol, facilitating the distribution of protocol returns, loan interest rate adjustments, risk control, and ecosystem incentives. By leveraging CHIP, USD.AI merges AI infrastructure financing returns with protocol governance, empowering token holders to participate in parameter decision-making and benefit from protocol value appreciation. This approach establishes a governance-driven, long-term incentive framework.

USD.AI primarily generates returns through AI infrastructure lending, offering financing to GPU operators and hash power infrastructure and earning loan interest. The protocol allocates these returns to holders of the yield asset sUSDai, while interest rates and risk parameters are managed via the CHIP governance token, creating an on-chain yield system anchored in AI hash power financing. This approach transforms real-world AI infrastructure returns into sustainable sources of return within the DeFi ecosystem.

RSR serves as the native utility token for the Reserve Protocol, with key functions including governance voting, risk buffering, and distribution of staking returns. RSR holders participate in protocol governance and help safeguard RTokens by staking RSR as risk protection. If the value of collateral assets falls and reserves become insufficient, the protocol liquidates staked RSR to restore reserves, ensuring the solvency of the stablecoin system.

Reserve Protocol's stablecoin, RToken, is supported by a diversified basket of on-chain assets and ensures solvency through Over-Collateralization and the RSR Stake mechanism. When users deposit collateral assets into the protocol, the system mints a corresponding amount of RTokens based on predefined rules. If the Asset Value of the collateral declines, the RSR Stake layer acts as a risk buffer to preserve the stability of the stablecoin system. This architecture allows Reserve Protocol to create asset-backed stablecoins and flexibly address various scenario demands through modular configuration.

Reserve Protocol is a decentralized protocol designed to create and manage asset-backed stablecoins. Stablecoins are issued with collateral from multiple on-chain assets, while system stability is maintained through governance and risk buffer mechanisms. The native token, RSR, fulfills the roles of governance, stake, and risk absorption within the protocol.

Reserve Protocol and MakerDAO are both protocols for creating decentralized stablecoins, but they use different stabilization mechanisms. MakerDAO generates DAI by requiring users to over-collateralize assets, while Reserve Protocol supports RTokens with a diversified asset basket and incorporates an RSR staking layer for risk mitigation. MakerDAO emphasizes a single stablecoin model, whereas Reserve Protocol offers a customizable stablecoin framework. These differences make MakerDAO ideal as a universal decentralized stablecoin protocol, while Reserve Protocol excels as a modular stablecoin infrastructure.

USDC maintains its peg to the US dollar through a 1:1 reserve backing model. When users deposit USD, Circle issues an equivalent amount of USDC on-chain; when users redeem USD, the corresponding USDC is burned. This mint-and-burn mechanism ensures that the circulating supply always matches the underlying reserves, making USDC a key stable asset in crypto trading, DeFi lending, and on-chain payments.

USDC is a US dollar stablecoin issued by Circle, backed by 1:1 dollar reserves to maintain price stability. It is widely used in cryptocurrency trading, DeFi lending, cross-border payments, and on-chain dollar settlement. As one of the most important compliant stablecoins on the market, USDC offers high transparency, strong liquidity, and multi-chain support. However, it also faces risks such as depegging, regulatory uncertainty, and reserve-related concerns. As on-chain finance continues to evolve, USDC is steadily becoming a key piece of dollar infrastructure in the Web3 ecosystem.

mantraUSD is a stablecoin issued within the MANTRA ecosystem, and its core function is to provide a stable unit of account and settlement for RWA asset trading.

As stablecoin regulation continues to progress, on-chain capital is shifting its focus away from high-volatility narratives toward assets that are compliant, accessible, offer verifiable returns, and provide deeper liquidity. This article systematically examines the primary directions and potential risks of future on-chain liquidity, drawing on regulatory frameworks, capital preferences, asset stratification, and practical metrics.
