JUSD is an oracle-free USD stablecoin, secured by Bitcoin and built for the Citrea Layer-2 ecosystem. It is decentralized by design, censorship-resistant, and offers a 10% yield on deposits.

cUSD is pegged 1:1 to the US Dollar, providing stability and a familiar unit of account. A reliable bridge between Bitcoin and the dollar economy, unlocked on Citrea.
JUSD operates entirely without external price oracles, eliminating a key point of failure. This makes it the only USD stablecoin truly independent and trust-minimized.
The JUSD Protocol lets you invest your cUSD at very attractive rates. With Savings, rewards accrue every block, providing recurring income automatically to your balance.
Fiat-backed stablecoins provide stability through regulation and bank reserves, but at the cost of flexibility, transparency, and user control.
In contrast, JUSD’s fully decentralized model empowers crypto-native users with true financial sovereignty. Get an overview:
The protocol offers opportunities for everyone — lenders, savers, users, and investors alike.
1. Mint
By depositing Bitcoin as collateral, anyone can mint JUSD — which must later be repaid to unlock the Bitcoin.
2. Fees
When minting JUSD, a small fee is paid into the reserve pool, strengthening the system’s security.
3. Sell
The minter can sell JUSD on the market for 1 USD each — and use it, e.g. to invest in ETH or other assets, all while keeping their Bitcoin.
4. Buy
CUSD can be bought on Juice Swap or other marketplaces.
5. Pay
CUSD can be used, e.g. for everyday payments.
6. Sell
Recipients can sell their CUSD back on the market at any time.
7. Buy
Someone interested in earning risk-free yield buys JUSD on the market to start saving.
8. Save
They deposit JUSD into the system without any lock-up period. Rewards start accruing immediately and are distributed with every block.
9. Interest
In return, the saver earns interest, paid out from the reserve pool.
10. Buy JUICE
Buy JUICE token to benefit from fee income and liquidation gains, and to take part in protocol governance.
11. Add capital
When adding capital to the equity reserve pool, you receive freshly minted JUICE token. The amount is determined using a bonding curve with the invariant 'Market Cap = JUICE Supply * JUICE Price = 3 * Equity Reserve Pool', minus a 2% issuance fee, which benefits CIPS holders.
12. JUICE appreciation or depriciation
After a minimum holding duration of three months, JUICE can be returned to the system at the current price, minus 0.3% redemption fee.

The goal is to establish a stablecoin that addresses the challenges faced by current stablecoins. These challenges include dependence on centralized oracles, reliance on centralized third parties, and limited collateral options for minting stablecoins.
Stablecoins are desperately needed, as seen by the developing digital financial scene, which has a total market capitalization of over 250 billion USD. They are essential to the cryptocurrency industry because they can store value during times of extreme volatility, make it easier for capital to move between exchanges, and allow for quick, inexpensive cross-border transactions. This is especially helpful in nations with high rates of inflation, as stablecoins can provide a reliable and easily available alternative to fiat money. Above all, they make possible a number of the most exciting DeFi applications.
Stablecoins as they exist today have drawbacks despite their apparent advantages. The two most often used ones, USDT (Tether) and USCD, rely on a single issuer. There are issues with openness and confidence arising from this. For instance, a group of businesses that own USDC has the authority to freeze money and add addresses to a blacklist. Furthermore, contrary to popular belief, the DAI, the most well-known decentralized stablecoin, is not very decentralized. It depends on oracles that might be influenced by players outside the system.
Oracle Manipulation Attacks are a type of attack in which an adversary exploits the data feeds (oracles) that smart contracts rely on to make decisions. By manipulating the data provided by oracles, attackers can trick smart contracts into executing transactions based on false information, often resulting in the theft of cryptocurrencies.
An example? With pleasure:
In April 2022 the Beanstalk Farms, a decentralized finance (DeFi) protocol built on Ethereum that issues its own stablecoin using a credit-based system rather than collateral, 182 million dollars were stolen through a flash loan exploit that manipulated the governance system via oracle pricing.This is just one of countless cases where funds were stolen through manipulated oracles.
Juice Dollar is intended to solve these issues on Citrea. It is a decentralized, Bitcoin-collateralized stablecoin that tracks the value of the US Dollar, built for the Citrea ecosystem.
JUSD is distinct in that it functions entirely without oracles. Its value is secured directly by Bitcoin collateral, with users — not oracles — determining that value. Through its exclusive auction-based minting mechanism, JUSD eliminates the need for external oracles, while ensuring full transparency and trust-minimization.
By removing major weaknesses in the conventional stablecoin concept, JUSD presents a more reliable, adaptable, and democratic stablecoin substitute. Because of its decentralized structure, it can function even in the absence of a conventional legal system since it lacks a central authority. Anyone can mint new coins and take part in the coin's governance thanks to the system's incentives and laws. This approach to stablecoin mechanics is essentially different.
The JUSD mechanism essentially creates money against collateral, just like a typical bank would. Users print their own money. Every process is transparent and automated.
