$XPL #Plasma Based on the core background differences of the three parties, I will elaborate from four dimensions: initiating ecology, positioning scenarios, technical mechanisms, and token models.

Plasma (XPL), Stable, and Arc are the three major stablecoin public chains, with core differences stemming from the essential distinctions in their initiating backgrounds and target ecologies. On the initiators' side, Plasma was founded in 2024 by Paul Faecks and his team, supported by capital such as Tether, balancing independent development with ecological synergy; Stable is the USDT native chain directly incubated by Tether in 2025, deeply binding itself to its stablecoin ecology; Arc is the USDC exclusive public chain launched by Circle in the same year, backed by enterprise-level financial resources.

Positioning and user scenarios form a distinct divide: Plasma primarily targets individual users and emerging markets such as Turkey and Argentina, with zero-fee USDT basic transfers at its core, covering scenarios like small payments and daily remittances, and also supports Bitcoin cross-chain interoperability and optional privacy transactions; Stable is aimed at all USDT ecosystem users, focusing on general stablecoin settlement, lowering the threshold for use through the native Gas design of USDT, adapting to broad needs such as daily payments and intra-ecosystem transfers; Arc precisely serves financial institutions and payment service providers, focusing on enterprise-level cross-border settlement and foreign exchange trading, with a built-in foreign exchange engine and compliance framework to meet institutions' high-level requirements for privacy and compliance.

Technology and performance have their own focuses: Plasma uses PlasmaBFT consensus, achieving sub-second confirmations and TPS exceeding 1000, while being compatible with EVM and realizing cross-chain capabilities; Stable also supports EVM, ensuring near-instant settlement and high throughput for smooth ecosystem operation; Arc pursues enterprise-level performance, with sub-second finality, achieving a TPS of up to 10000 in a 4-node environment, focusing on compliance and privacy technology optimization.

The differences in token and fee mechanisms are significant: Plasma issues a total supply of 10 billion XPL tokens, with basic transfers handled by USDT to achieve zero fees, while complex operations and governance require the consumption of XPL; Stable and Arc have no native tokens, respectively using stable coins such as USDT, USDC/EURC as Gas, the former focusing on user convenience, and the latter on predictable enterprise costs. The three are adapted to meet the needs of individual users, general ecosystems, and institutional professionals, forming a differentiated competitive landscape for stablecoin public chains.
