StableCoin

Circle xStock is a financial infrastructure model built around onchain stock assets, or Tokenized Stock. Its core goal is to map traditional stock assets onto blockchain networks and combine them with stablecoins, smart contracts, and onchain liquidity systems to enable more open, globalized securities trading and asset settlement. As the RWA, or Real World Assets, market develops, more institutions are paying attention to the structural changes in finance brought by the integration of onchain securities and digital assets.

Circle Tokenized Stock (xStock) is an on-chain stock token structure issued on blockchain infrastructure. Its core goal is to map traditional stock prices into an on-chain trading environment and combine them with stablecoins and digital asset infrastructure to create a more open model for global asset circulation.

Circle Tokenized Stock (xStock) is a blockchain-based stock tokenization product. Its core purpose is to give users exposure to traditional stock prices within the crypto ecosystem through an onchain asset structure. As RWA, or real-world assets, becomes an increasingly important direction for the crypto industry, onchain stock tokens are also emerging as a key piece of infrastructure connecting traditional finance with Web3.

Ripple USD (RLUSD) is a dollar-backed stablecoin issued by Ripple. It is pegged to the U.S. dollar at a 1:1 ratio and deployed on both XRP Ledger (XRPL) and Ethereum. RLUSD is mainly used for cross-border payments, on-chain settlement, institutional fund transfers, and decentralized finance (DeFi) scenarios. Its goal is to provide a more stable digital settlement asset within Ripple’s payments ecosystem.

Kaia (KAIA) is an EVM-compatible Layer 1 blockchain formed through the merger of Klaytn, which was supported by South Korea’s internet ecosystem, and Finschia, LINE’s Web3 network. It focuses on stablecoin payments, on-chain finance, and Web3 application infrastructure. Through a high-performance network, low transaction costs, and integration with super app ecosystems such as LINE, Kaia aims to support large-scale Web3 user onboarding in Asia and enable use cases such as DeFi, payments, RWA, and Mini DApps.

TRON and LI.FI have successfully integrated, allowing Stablecoins to move seamlessly across various blockchains. In this article, we’ll explore how this partnership streamlines cross-chain transactions and elevates the DeFi user experience.

PYUSD, USDT, and USDC are among the major U.S. dollar stablecoins in today’s market. All three aim to maintain price stability by pegging their value to the U.S. dollar, but they differ significantly in issuer, reserve mechanism, regulatory compliance, and use cases. USDT has the largest market liquidity and trading usage, USDC is known for high transparency and strong regulatory compliance, while PYUSD relies on PayPal’s payment ecosystem and has meaningful potential in payment applications.

PayPal launched PYUSD primarily to expand its digital payment infrastructure and capture the digital dollar payments market amid the rapid growth of stablecoins. By issuing a stablecoin backed by U.S. dollar reserves, PayPal can improve cross border payment efficiency while connecting traditional payment networks with the blockchain finance ecosystem. PYUSD is an important part of PayPal’s digital finance strategy. Its launch not only strengthens PayPal’s competitiveness in the global payments market, but also signals that stablecoins are beginning to move more quickly into mainstream payment systems.

PayPal USD (PYUSD) is a U.S. dollar stablecoin launched by PayPal. It is issued by Paxos Trust Company and backed by reserves of U.S. dollar deposits and short term U.S. Treasury securities, allowing it to maintain a 1:1 peg to the U.S. dollar. Built on Ethereum as an ERC-20 token, PYUSD can be used for payments, transfers, and digital asset settlement. As a major step by a traditional payments giant into blockchain finance, PYUSD not only strengthens the potential use of stablecoins in payment scenarios, but also helps move stablecoins closer to the mainstream financial system.

Terra Classic (LUNC) is a blockchain protocol and token designed to support an algorithmic stablecoin system and an on-chain payment network. Its core mechanism is based on a supply and demand adjustment model between stablecoins and the native token. As demand for DeFi and stablecoins grew, Terra Classic was once widely used in on-chain payments, trading, and asset issuance.

Food delivery platform DoorDash is set to implement a stablecoin payment system, utilizing blockchain technology to improve settlement efficiency and lower costs. This article examines the partnership model and its potential implications for the payments industry.

USD.AI generates yield primarily through AI infrastructure lending by providing financing to GPU operators and compute infrastructure providers and collecting loan interest. These returns are distributed to sUSDai holders, while the governance token CHIP manages interest rates and risk parameters. This model creates an on-chain yield system backed by AI compute financing, allowing real-world infrastructure revenue to become a sustainable source of DeFi yield.

CHIP is the core governance token of the USD.AI protocol, designed to coordinate yield distribution, loan interest rate adjustments, risk management, and ecosystem incentives. Through CHIP, USD.AI aligns AI infrastructure financing returns with protocol governance, enabling token holders to participate in parameter decisions and share in the protocol’s value growth. This creates a governance-driven, long-term incentive system.

USD.AI enables AI infrastructure financing by using GPUs and other compute assets as collateral within an on-chain lending and yield distribution system. Users deposit stablecoins to mint USDai, while the underlying capital is deployed into GPU-backed loans that generate returns. These returns are distributed to sUSDai holders, effectively transforming AI compute assets into yield-generating on-chain credit instruments and forming a DeFi credit market tailored to AI infrastructure.

USD.AI is a yield-bearing synthetic dollar protocol focused on financing AI infrastructure. By combining stablecoins with GPU-backed lending, it creates a dual-token system consisting of USDai (the stable layer) and sUSDai (the yield layer). The governance token CHIP coordinates interest rates, risk parameters, and yield distribution, enabling the financialization and liquidity expansion of physical AI compute assets.
