JupUSD jupusd

JupUSD is a Solana-native stablecoin designed to track the U.S. dollar at a 1:1 value. It is issued by Jupiter in partnership with Ethena and is represented as an SPL token on Solana. The official mint is JuprjznTrTSp2UFa3ZBUFgwdAmtZCq4MQCwysN55USD.

JupUSD is reserve-backed rather than algorithmically collateralized by JUP or another volatile token. The target reserve mix is 90% USDtb and 10% USDC; the composition may move after large mint or redemption flows and is rebalanced daily. USDtb itself is described by the JupUSD site as an Ethena stablecoin whose reserves include BlackRock's BUIDL fund.

The token is intended as a base dollar asset for Jupiter's product suite and Solana DeFi. Jupiter documents use cases across Spot trading, Jupiter Lend, JUICED, and broader Solana applications; the JupUSD site also presents it as a planned core settlement and liquidity asset for Perps, Mobile, and Prediction Markets. JupUSD itself does not pass reserve yield to holders. Users seeking yield can convert it to JUICED, subject to that product's separate risks and terms.

Onchain finance needs a dollar-denominated settlement and liquidity asset, but users and protocols also need transparent backing, predictable redemption mechanics, and integrations that work on Solana. JupUSD addresses this by combining an SPL token with a dedicated mint/redeem program and publicly disclosed reserve addresses.

The design does not remove stablecoin risk. Direct primary-market access is restricted to KYC/KYB-approved market makers and institutional partners, so retail users generally obtain JupUSD through swaps and secondary markets. The peg can be affected by market liquidity, custodian or issuer dependencies, oracle availability, smart-contract faults, or disruption involving USDtb and its underlying reserves.

Approved benefactors deposit USDC or USDtb into the dedicated Solana program. The program uses collateral and configured oracle data to calculate the exchange amount, charges a 0.04% mint fee, and issues JupUSD to the user's token account. Redemption burns JupUSD and returns the corresponding collateral, also subject to a 0.04% program fee and minimum-output/slippage protection.

The reserves are held through Anchorage's Porto custody infrastructure, with collateral also moving between the onchain program vault and custodial reserves to maintain redemption liquidity and the target composition. The published key addresses include the JupUSD program, custodian reserve account, program-reserve account, and update-authority multisig. Reserve composition and backing information are intended to be independently checkable through the JupUSD transparency page, while onchain activity is available through Solscan and a Dune dashboard.

JupUSD's peg relies on authorized market-maker arbitrage and an automated peg bot. If the token trades below $1, a market maker can buy it and redeem at par; if it trades above $1, an authorized participant can mint and sell. Minting and redemption are rate-limited at global, vault, and benefactor levels, and the developer documentation provides an SDK, Web API, and UI integration paths.

Retail users do not need KYC to buy or hold JupUSD through Jupiter Swap, Jupiter Mobile, or supported Solana venues, but they cannot directly call the primary mint/redeem flow unless onboarded. The mint/redeem program is source-available under the Business Source License (BSL), and the documentation links three independent audit reports from Offside Labs, Guardian, and Pashov.
