# About BIMA ### Overview BIMA is a DeFi ecosystem that empowers professional and retail investors to access permissionless institution-grade yield strategies globally, without selling their Bitcoin. It does so with “USBD,” a capital-efficient stablecoin over-collateralized by Bitcoin derivatives. 1. Investors can invest Bitcoin directly or stake their BTC to receive liquid-staking derivatives (LSTs). 2. Investors place either Bitcoin or LSTs into BIMA vaults with varying risk-reward profiles — ranging from delta-neutral investment strategies earning 15-20% APY to higher-volatility strategies capable of earning between 30-60% APY. 3. Investors mint USBD and earn sUSBD, which represents their staked collateral and unlocks further opportunities to earn yield and maximize capital efficiencies. BIMA’s crypto collateralization and decentralization makes USBD a more scalable and secure solution than traditional fiat stablecoins, such as USDC or USDT. BIMA also offers investors a multi-strategy portfolio of choices when it comes to how much risk they take on and how much yield they could potentially earn — a stark difference from previous Bitcoin stablecoin models that offer limited investment options. **`Key Features:`** * `Permissionless access to varied yield strategies through BIMA Vaults` * `Varied risk-reward profiles, from 15% low-volatility to 60% high-volatility APY` * `Yield rewards in Bitcoin and other crypto assets, varying by vault strategy` * `Permissioned institutional borrowing with 160% over-collateralization` * `No smart contract risk, with BTC collateral placed in qualified custody` * `Decentralized governance and security through the [REDACTED] token` {% embed url="" %} **The USBD Stablecoin** USBD is a dollar-pegged stablecoin primarily backed by Bitcoin derivatives, optimizing capital efficiency, scalability, and decentralization. USBD maintains stability through a number of features, including over-collateralized vaults, automated liquidity mechanisms, stability fees, collateral-specific debt ceilings, and decentralized price oracles. These stability features are further detailed in “Risk Management and Liquidation” **Earning with USBD + sUSBD** BIMA combines stability and simplicity with a variable lending rate for USBD, earning lenders a variable 3-5% awarded in “sUSBD” (staked USBD). This ensures borrowers have reliable access to capital against their collateralized assets while ensuring fair, sustainable returns for lenders — whose position is represented in sUSBD, which accrues additional rewards for them over time and allows them to invest in institutional yield-bearing strategies through BIMA Vaults. *Learn more about how it works in “Secure Bitcoin Preservation and Yield”*
**Earning with BIMA Vaults** Unlike stablecoins that offer just one, or a few, yield strategies for investors, the BIMA ecosystem actively attracts and integrates numerous institutional investment vehicles — called “vaults” — for its holders to choose from. *Vault examples, including potential APY, are detailed in “Institutional Yield-bearing Strategies”*
**Institutional-Grade Security** *BIMA undergoes rigorous security audits from best-of-class operators, employs cold storage for reserves, and offers a bug bounty program for ethical hackers reporting vulnerabilities.*\ \ *Latest updates in “Security”*
