What is Bucket USD (USDB)?
Bucket USD (USDB) is a stablecoin designed to maintain a value equivalent to the US dollar. It is issued by the Bucket Protocol, which operates on the Sui blockchain. The Bucket Protocol is a Collateralized Debt Position (CDP) platform where users can deposit supported on-chain assets as collateral to borrow USDB. This system allows users to obtain liquidity without selling their primary assets or to create leveraged positions. The protocol focuses on capital efficiency and aims to provide borrowing with predictable, fixed costs. To maintain its peg to the US dollar, USDB utilizes a Peg Stability Module (PSM) for 1:1 conversions between USDB and other supported stablecoins, along with market arbitrage mechanisms. Debt positions within the Bucket Protocol are represented by unique non-fungible tokens (NFTs). Beyond its use as collateral for borrowing, USDB can also be held in the sUSDB Savings Pool by stablecoin allocators to earn yield. It is important to note that the ticker symbol USDB is also used by other projects with different characteristics. For example, some USDB tokens are described as multi-chain stablecoins backed by Bitcoin, employing a proof-of-burn mechanism for stability and operating on Bitcoin's Spark layer-2 and the XRP Ledger. Another iteration of USDB is associated with the Blast Ecosystem, where it functions as a decentralized stablecoin collateralized by USDC and ETH reserves and offers yield-generating features to holders through an "auto-staking" model. Additionally, the Braza Group also issues a USDB stablecoin, which is pegged to the US dollar and designed for low-cost, instantaneous cross-border transactions. Learn more

Bucket USD (USDB) FAQ
USDB is a stablecoin pegged to the US dollar, designed to provide price stability in the volatile cryptocurrency market. It is backed by Bitcoin and operates on second-layer blockchains like Blast Ecosystem and Spark to enhance transaction speed and scalability. USDB is a multi-chain stablecoin, operating natively on Bitcoin's Spark layer-2 and the XRP Ledger. It was rebranded from BUCK to USDB on September 1, 2025, as part of a major protocol upgrade.
USDB maintains its peg through a multi-faceted approach. It utilizes a proof-of-burn mechanism that dynamically adjusts token supply based on market demand, balancing the supply with backing assets. Arbitrage opportunities are key; if USDB's value deviates from $1, arbitrageurs can profit by buying or selling, which helps restore the peg. Additionally, the Bucket Protocol integrated a Peg Stability Module (PSM) on January 1, 2024, enabling 1:1 swaps with other approved stablecoins like USDC to further enhance its stability.
USDB distinguishes itself through its decentralized backing by Bitcoin and its innovative proof-of-burn mechanism for dynamic supply adjustment. Its operation on second-layer blockchains like Blast Ecosystem and Spark provides benefits such as faster transactions and lower fees. It also deeply integrates with decentralized finance platforms and yield-generating protocols, expanding its utility. Some versions may also hold U.S. Treasury bills or government bonds, offering a blend of decentralization and a focus on compliance for regulatory adherence.
USDB serves various financial applications, including acting as a stable medium for trading, storing value, and participating in decentralized finance (DeFi) platforms. It facilitates seamless cross-border transactions and offers opportunities for yield generation. Its stability also makes it attractive for investors looking to hedge against cryptocurrency market volatility. Within the Bucket Protocol, users can borrow USDB against collateral (like SUI, BTC, or ETH on Sui), leverage assets, park stablecoins in savings for yield, and engage in liquidity farming in decentralized exchange pools.
USDB leverages multiple advanced blockchain technologies. It is built on the Blast Ecosystem, a second-layer solution designed for scalability and reduced transaction costs. It also operates natively on Bitcoin's Spark layer-2 and the XRP Ledger, utilizing advanced cryptographic techniques and consensus mechanisms, including aspects of proof-of-stake. The underlying Bucket Protocol itself is deployed on the Sui blockchain, benefiting from its object-centric architecture for efficient and secure management of collateralized debt positions.
USDB's regulatory status is nuanced; while certain aspects mention regulated reserves and being issued by licensed entities, it's also described as fully decentralized and not subject to a federated multisig. Key historical milestones include its founding on December 3, 2025, the integration of a Peg Stability Module on January 1, 2024, and its rebranding from BUCK to USDB on September 1, 2025, as part of a significant protocol upgrade.
