TL;DR
- Jupiter launches JupUSD, a new stablecoin, alongside a broader package of infrastructure upgrades.
- JupUSD aims to be a decentralized, transparent, and over-collateralized stablecoin.
- The upgrades are part of Jupiter’s ongoing strategy to become a central DeFi hub on Solana.
Jupiter launched JupUSD, a new stablecoin built with Ethena, and announced seven coordinated platform upgrades. The plan adds a Developer Platform, a trading Terminal, and the acquisition of Rain.fi.
The decentralized exchange reports $1.08 trillion in combined spot and perpetuals volume in 2025 and holds $2.7 billion in TVL. With the bundle, the team targets fragmented data, counterfeit assets, and the lack of professional-grade tools.
The stablecoin for onchain finance has arrived.
Introducing: JupUSD
A reserve-backed stablecoin pegged to the US Dollar, designed to power the next chapter of finance.

Users apply the stablecoin in DCA orders, limit orders, and prediction markets, with native routing through the aggregator and its perp and lending modules. Executives argue that running both the dollar unit and the execution rails creates measurable synergies: higher retention, lower friction, and a value loop that returns to the protocol through more trades and interest.
JupUSD integration and network effects on Solana
JupUSD enters with deep integration, which already handles billions in stablecoin volume via swaps, perpetuals, and lending. The result aims at an end-to-end stack: issuance, routing, liquidity, and execution tools in one circuit. Listing controls and live monitoring seek to cut counterfeit listings and improve liquidity and slippage signals.
Western Union plans a US Dollar Payment Token on Solana with Anchorage Digital Bank in H1 2026 for cross-border remittances. In parallel, the Solana Foundation and Wavebridge are building a compliance-ready KRW-pegged stablecoin as South Korea advances its legislative framework. These moves raise competition for stable deposits and add more settlement pairs for DEX and lending venues.
On credit, Jupiter Lend exited beta, went fully open source, and surpassed $1 billion in total supply in eight days. The team links the pace to curated listings, constrained incentives, and direct integration with the aggregator. Pairing JupUSD with Lend reduces product hops and trims hidden costs for end users.
The package also introduces a Terminal with unified execution, risk dashboards, and auditable market feeds. The Developer Platform standardizes build kits, permissions, and testing, and clarifies how external teams plug into core Jupiter modules. The Rain.fi acquisition adds expertise in collateralized lending and pricing for less liquid assets, where clear metrics and predictable liquidations matter.
