barefi – TypeScript reference client + simulator for a minimum‑viable Bitcoin DeFi stack: over‑collateralized bareUSD stablecoin, CDP vaults with liquidation math, rBTC‑style liquid staking receipts, and a barefi‑cli to drive the flows locally. Educational foundation for OP_NET, BitVM, or Stacks.

AI Summary

barefi is an educational simulator that teaches people how Bitcoin-backed decentralized finance works. It recreates a simplified version of a 'minimum viable bank on Bitcoin' where users can open vaults (locked collateral positions), mint stablecoins against their Bitcoin, participate in liquidations, and try liquid staking—all in a safe local environment with pretend money. The project is explicitly designed as a learning tool with no connection to real networks or actual funds.

How It Works

1
💡 You discover Bitcoin DeFi

You've heard about borrowing and lending with Bitcoin, but everything feels complicated and risky. You find a local simulator that teaches you how it all works.

2
🛠️ You set up the simulator

You download and run a simple program on your computer that creates a safe, fake Bitcoin world where you can experiment without losing real money.

3
💰 You get free test credits

The simulator gives you pretend Bitcoin and stablecoins so you can try everything out without any cost or risk.

4
🏦 You open a vault and deposit collateral

You lock up your test Bitcoin as collateral and receive a vault that tracks your position and health in real-time.

5
You explore different paths
🪙
Mint stablecoins

You borrow bareUSD against your locked Bitcoin, like taking a loan backed by your savings.

📈
Try liquid staking

You stake your Bitcoin and receive receipt tokens that track your share of the pool and any yield earned.

⚡
Watch liquidation scenarios

You simulate price crashes to understand how vaults become unsafe and what triggers protective measures.

6
📊 You monitor your portfolio

A dashboard shows all your vaults, staking positions, and risk levels so you always know where you stand.

🎓 You understand Bitcoin DeFi

You've learned how collateral, loans, liquidation, and staking work together—and you're ready for the real thing.

AI-Generated Review

What is barefi?

barefi is a TypeScript simulator that models a minimum-viable Bitcoin DeFi bank: an over-collateralized stablecoin called bareUSD, debt positions with liquidation protection, and a liquid staking pool that issues rBTC-style receipt tokens. You interact with it entirely through a CLI that lets you create vaults, mint stablecoins against Bitcoin collateral, trigger liquidations, and manage staking positions—all running locally without touching mainnet. The simulator includes an oracle price feed, stability fee accrual, and an append-only event log so you can replay and audit every state change.

Why is it gaining traction?

This project targets a specific gap: Bitcoin DeFi protocols like OP_NET and BitVM are emerging, but there's no easy way to learn the risk math and user flows before committing to a specific execution environment. barefi freezes the core protocol logic—collateral ratios, liquidation bonuses, interest accrual—in portable TypeScript that you can later port to Wasm contracts or bridge to other chains. The CLI-first design with JSON output makes it scriptable, which matters for developers building automation around vault management or liquidator bots.

Who should use this?

DeFi protocol designers exploring Bitcoin-backed lending will find the vault engine and liquidation math immediately useful for prototyping without deploying anything on-chain. Developers evaluating OP_NET, BitVM, or Stacks for a lending product can use barefi as a reference implementation to validate their mental models. Early-stage projects building liquidation incentive systems can test edge cases—like oracle shocks or partial repayments—against a deterministic local state before writing production contracts.

Verdict

barefi earns a credibility score of approximately 0.9%, which reflects its early stage: 16 stars and version 0.2 with limited documentation. Test coverage is solid for the core protocol math, but this remains a learning tool, not production infrastructure. If you need to internalize how Bitcoin-backed stablecoins behave under various conditions, this is the fastest on-ramp available—and the architecture makes eventual porting to real Bitcoin L2s straightforward. Treat it as educational scaffolding, not a live protocol.
