StableCoin

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.

Ethena (ENA) is a decentralized stablecoin protocol leveraging a derivative hedge mechanism. It aims to create a stable asset, USDe, without relying on traditional fiat reserves by hedging on-chain assets and derivatives marketplaces. As stablecoins become more integral to the DeFi ecosystem, Ethena introduces a novel stabilization approach that differs from both fiat-collateralized and over-collateralized stablecoins.

Ethena is a synthetic dollar protocol built on Ethereum. Its core stablecoin, USDe, maintains price stability using a delta-neutral hedging mechanism. Unlike traditional stablecoins that depend on fiat reserves, Ethena achieves stability by holding crypto assets and opening derivative short positions to hedge against price volatility.

Ethena (ENA) serves as the primary governance token within the Ethena protocol, playing a central role in protocol governance, ecosystem incentives, and network security. Unlike tokens intended exclusively for Trade or payments, ENA is specifically structured to prioritize governance and ecosystem coordination, establishing it as a vital element of the Ethena 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.

Tether, the leading stablecoin provider, has introduced a new self-custodial wallet app, seeking to shift its long-term position as a foundational payment infrastructure into a user-facing product. This article examines the wallet’s design features, supported assets, and the strategic vision driving its development.

The role of idOS in stablecoin ecosystems lies in providing a reusable on-chain identity infrastructure that allows users to share verified identity data across different financial applications. Through encrypted storage and permissioned access, idOS enables stablecoin platforms to verify user identities without requiring repeated KYC processes, reducing compliance costs while improving user experience. By introducing an identity layer, stablecoins can meet regulatory requirements without compromising privacy, serving as a crucial bridge between on-chain finance and the real world.

The core mechanism of idOS revolves around “encrypted storage plus access authorization (Access Grant).” User identity data is first verified by an issuer and then encrypted and stored within the idOS network. Applications, known as consumers, can only access this data after receiving user authorization. Through this process, idOS enables reusable identity data, protects privacy, and allows secure data portability across applications, making it possible to use sensitive information like KYC across platforms without repeated submissions.

idOS (IDOS) is a Web3 identity layer that provides users with portable identity verification and self-custodied data storage, allowing KYC information to be reused across platforms. By linking identity to blockchain addresses, idOS addresses fragmentation and repetitive verification in Web3, emerging as a critical infrastructure connecting users, applications, and compliance systems within the stablecoin economy.

This article examines the stablecoin liquidity environment, leveraging key metrics including total stablecoin supply, net inflows, exchange reserves, on-chain migration, and BTC market share. It demonstrates how a single metric can reveal shifts in crypto market risk appetite and the rhythm of sector rotation. Additionally, it offers a weekly monitoring checklist, position management guidelines, and strategies for correcting misjudgments, empowering investors to improve decision-making consistency and risk control efficiency in bullish, sideways, and drawdown scenarios.

This article provides a systematic analysis of how, in the wake of increased stablecoin regulation, the competition between USDT and USDC has evolved from a focus on issuance scale to an emphasis on compliance capabilities, distribution channels, on-chain liquidity, and commercialization efficiency. It further examines the stratified competitive landscape between the two across trading, payments, institutional adoption, and emerging marketplaces, while exploring potential future developments.

USAT (USA₮) is a compliant stablecoin backed primarily by short-term U.S. Treasury securities, designed to maintain a 1:1 peg with the U.S. dollar. It is built for institutional-grade on-chain settlement and treasury management. Issued in partnership with regulated financial institutions, it emphasizes asset transparency, high liquidity, and low risk. Unlike most stablecoins, USAT does not distribute yield to holders. Instead, it is positioned as an “on-chain cash equivalent,” suitable for exchange settlement, institutional payments, and cross-border fund transfers.

USAT (USA₮) maintains a 1:1 peg to the U.S. dollar by allocating user funds into highly liquid, low-risk U.S. Treasury assets. This model represents a typical RWA (Real World Asset) stablecoin approach, where stability is derived from the creditworthiness of U.S. government debt and its ability to be quickly converted into cash. Compared to other stablecoins, USAT improves transparency and institutional trust by simplifying its reserve structure and emphasizing high-quality assets, though it still faces risks such as interest rate fluctuations, regulatory changes, and centralized custody.
