What is JupUSD?
JupUSD is a Solana-native stablecoin pegged 1:1 to the U.S. dollar, built by Jupiter in partnership with Ethena. Each JupUSD token is backed by reserve assets held in custody. The target reserve composition is 90% USDtb and 10% USDC. This ratio can fluctuate following large mints or redeems, and is automatically rebalanced daily. Reserve data is publicly verifiable on the JupUSD Transparency page.JupUSD does not generate yield on its own. To access yield from the underlying reserves, see JUICED.

How JupUSD works
JupUSD is minted and redeemed against reserve assets. Each token is backed 1:1 by reserves held in an Anchorage Porto Wallet. The process works as follows:- Minting transfers collateral (USDC or USDtb) to the custodian and issues new JupUSD tokens in return.
- Redeeming burns JupUSD tokens and returns the corresponding collateral to the user.
Peg stability
JupUSD’s peg to $1 is maintained through two mechanisms:- Market maker arbitrage. Authorised market makers with direct mint/redeem access arbitrage price differences across Solana trading venues. If JupUSD trades below 1, they can mint new JupUSD and sell it.
- Automated peg bot. An automated bot monitors the JupUSD price and uses the mint/redeem program to correct deviations from the $1 peg.
Fees
A 0.04% fee (of the transaction amount) applies to all mint and redeem transactions through the JupUSD program. Swaps involving JupUSD on DEXs or aggregators (including Jupiter Swap) are subject only to the platform’s standard trading fees. The 0.04% mint/redeem fee does not apply to swaps.Fees and other program parameters may be updated over time. This page reflects current values at the time of writing.
Yield
JupUSD does not accrue yield. Holding JupUSD in your wallet does not generate any return. The reserves backing JupUSD (primarily USDtb, which is backed by BlackRock’s BUIDL fund) generate T-bill yield (interest from U.S. Treasury-backed reserves). However, this yield is not passed through to JupUSD holders directly. For full details on how yield works, see the JUICED page.How to get JupUSD

Risks
Like all onchain assets, JupUSD carries risks that cannot be fully eliminated. Users should understand the following before interacting with JupUSD.Smart contract risk
Smart contract risk
JupUSD relies on Solana programs for minting, redemption, and peg stability. While these programs have been audited (see below), bugs or vulnerabilities in smart contracts can never be fully ruled out.
Custodian risk
Custodian risk
Reserve assets are held in an Anchorage Porto Wallet. Users are exposed to the operational and security risks of the custodian. If the custodian were compromised or unable to operate, access to reserves could be delayed or impaired.
Third-party platform risk
Third-party platform risk
JupUSD depends on Ethena (USDtb issuer) and the underlying assets (including BlackRock’s BUIDL). Changes in the operations, solvency, or regulatory status of these third parties could affect JupUSD’s backing.
Liquidity and market risk
Liquidity and market risk
Under extreme market conditions, JupUSD may temporarily trade away from its $1 peg. Redemption liquidity depends on the available collateral in the onchain program vault, which is periodically replenished from custodial reserves.
Oracle risk
Oracle risk
The JupUSD mint/redeem program uses Pyth oracle feeds to validate collateral pricing. If oracle data is unavailable or unreliable, mint and redeem operations may temporarily fail. There is no fallback oracle mechanism.
