BIMA primary-source snapshot

Fetched: 2026-05-08 UTC

1) Official docs overview

Source: https://docs.bima.money/about-bima.md Source: https://bima.money/

Selected excerpts from the official materials:

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.

Investors place either Bitcoin or LSTs into BIMA vaults with varying risk-reward profiles.

Investors mint USBD and earn sUSBD.

Additional signals from the source:

  • BIMA is not only pitching a BTC-backed CDP stablecoin; it is also pitching a vault-curation and yield-distribution layer on top of that borrowing system.
  • The ecosystem framing is important because it pushes BIMA beyond the usual “borrow stablecoins against BTC” positioning.

2) Documentation map and live surface area

Source: https://docs.bima.money/sitemap.md

Selected excerpts from the official docs:

  • The sitemap exposes pages for About BIMA, Yield with USBD + sUSBD, Secure Bitcoin Preservation, Institutional-Grade Vault Strategies, Minting USBD, Redeeming USBD, Configuration Details, Risk Management + Liquidations, The Peg Stability Module, Security, Mainnet Addresses, BIMA Credit Score, and FAQ.

Additional signals from the source:

  • The docs are structured like a protocol plus product stack, not merely a token landing page.
  • The presence of vault strategy, mainnet address, and risk-management pages suggests BIMA wants to be integrated and evaluated as infrastructure.

3) Borrow/lend loop, stability pool, and Earn program

Source: https://docs.bima.money/yield-with-usbd-+-susbd/secure-bitcoin-preservation.md

Selected excerpts from the official docs:

USBD can now serve as both a stable source of income and a tool for unlocking liquidity.

Lenders deposit USBD into BIMA’s lending pool and earn a variable annual yield.

When a borrower’s collateralized loan falls below the required ratio, their position is liquidated, and the Stability Pool absorbs the liquidated collateral.

The Earn program introduces a multitude of yield-bearing vaults, unlocking opportunities for BTC holders and USBD stakers to generate stable and sustainable yields.

Users stake USBD into yield-bearing vaults to receive sUSBD.

Additional signals from the source:

  • This page makes the mechanism lens much clearer: BIMA is trying to bundle CDP borrowing, liquidation backstop capital, and managed-yield wrappers into one self-reinforcing BTC liquidity loop.
  • The Stability Pool language also makes BIMA look meaningfully influenced by the Liquity-style trove/stability-pool pattern, even though the collateral focus is BTC and BTC-adjacent assets.

4) Sample vault strategy surface

Source: https://docs.bima.money/yield-with-usbd-+-susbd/institutional-grade-vault-strategies.md

Selected excerpts from the official docs:

BIMA vaults allow both major liquidity providers and retail users to access dozens of institutional-grade yield opportunities.

Each vault represents a different yield strategy — from delta-hedging large caps like BTC, ETH, or SOL to perpetual futures and deliverable contracts.

These vaults are provided by independent entities within the BIMA ecosystem.

Additional signals from the source:

  • The docs frame BIMA as a distribution layer for third-party strategy providers, not just a single risk engine.
  • That means practical authority may sit partly with vault providers and curators, not only with CDP governance.

5) Risk management and liquidation rules

Source: https://docs.bima.money/risk-management-+-liquidations.md Source: https://docs.bima.money/faq.md

Selected excerpts from the official docs:

if you mint USBD, your crypto assets … must be locked in at a 160% minimum collateralization ratio.

liquidations in BIMA are manual—they are executed by external actors, referred to as liquidators.

liquidators receive a reward of 0.5% of the liquidated collateral, along with a fixed bounty of 200 USBD.

The FAQ says USBD stability relies on automatic liquidation mechanisms.

Additional signals from the source:

  • The docs consistently describe over-collateralization, debt ceilings, decentralized price oracles, stability fees, and governance-adjusted parameters.
  • There is a meaningful documentation inconsistency: the risk-management page says liquidations are manual and executed by external liquidators, while the FAQ describes automatic liquidation mechanisms.
  • That inconsistency is analytically useful because it suggests either evolving design or uneven documentation around a core risk surface.

6) Peg Stability Module

Source: https://docs.bima.money/risk-management-+-liquidations/the-peg-stability-module.md

Selected excerpts from the official docs:

The BIMA Peg Stability Module (PSM) is a mechanism designed to help USBD maintain its $1 USD peg by enabling direct, permissionless swaps between USBD and other stablecoins at a fixed 1:1 rate.

Bima governance can adjust fees, debt ceilings, and supported assets to control USBD supply and peg pressure.

Counterparty risk: Introduces centralized risk (e.g., USDC exposure), but helps stabilize USBD during demand surges.

Additional signals from the source:

  • BIMA is not relying only on crypto-collateral arbitrage; it is also importing a Maker-style PSM stabilization tool.
  • The docs explicitly acknowledge the centralization tradeoff, which is a useful classification clue.

7) Security and reserves posture

Source: https://docs.bima.money/security.md Source: https://docs.bima.money/security/mainnet-addresses.md Source: https://github.com/Bima-Labs/bima-core-audits

Selected excerpts from the official materials:

The assets backing the USBD stablecoin are held securely in cold storage.

BIMA is currrently live on: Ethereum Mainnet, Core Mainnet, Hemi Mainnet, Plume Mainnet, Sonic Mainnet, Goat Mainnet, Botanix Mainnet, BSC Mainnet, Nibiru Mainnet.

This repository contains all security audits, code reviews, and formal verification reports conducted on the Bima Protocol smart contracts.

Additional signals from the source:

  • The mainnet-address page shows BIMA has already pushed the same protocol surface across multiple EVM environments.
  • The public audits repository makes BIMA more legible as infrastructure rather than only a marketing site.

8) GitHub organization surface

Source: https://github.com/Bima-Labs Source: https://github.com/Bima-Labs/bima-v1-core

Selected excerpts/signals from the public GitHub org:

  • Public repos include bima-v1-core, bima-core-audits, bima-yb-core, trustless-vaults, and governance/UI repos.
  • The core audits repo describes BIMA as enabling “BTC LST staking, liquidity vaults, and the minting of USBD.”

Why it mattered:

  • The repo layout reinforces the two-layer picture from the docs: a base borrowing/stablecoin system plus a separate yield-bearing and vault-management surface.

Whitepaper note

  • No canonical standalone whitepaper or litepaper surfaced in this pass.
  • The clearest current first-party sources were the official site, docs corpus, public mainnet address page, and GitHub/audit surfaces.

Working conclusion

BIMA is best cataloged as Bitcoin-backed CDP stablecoin infrastructure / BTC-yield routing layer / stability-pool-and-PSM hybrid. The most reusable insight is that it combines a trove-like over-collateralized borrowing core with a managed vault marketplace, so the key diligence question is not just whether USBD is safely collateralized, but who controls the yield strategies and backstop layers wrapped around that collateral.
