# Libre > Libre is a peer-to-peer Bitcoin lending marketplace. Users borrow USDT against BTC collateral or lend stablecoins to earn predictable yield, with loans overcollateralized by Bitcoin (typically 200%+). Libre's marketing site is a single page at https://www.libre.org/ that explains how the protocol works, lists current loan rates and pool stats, and links out to the live dApp at https://defi.libre.org for borrowing and lending. On-chain loan data is viewable at https://tools.libre.org. Loan terms range from 1 week (5% APR) up to 6 months (13% APR). All loans are fully collateralized with Bitcoin held on-chain. ## Main site - [Homepage](https://www.libre.org/): Overview, rates, stats, security model, team, and contact form - [Borrow section](https://www.libre.org/#borrow): Loan rate table and live pool statistics - [Lend section](https://www.libre.org/#lend): Information for stablecoin lenders - [Security](https://www.libre.org/#security): Overcollateralization details and risk model - [How it works](https://www.libre.org/#how-it-works): Protocol mechanics - [Team](https://www.libre.org/#team): Team members - [Contact](https://www.libre.org/#reach-the-network): "Reach the Network" contact form ## Application - [Libre dApp](https://defi.libre.org): Launch the app to borrow or lend - [Borrow USDT](https://defi.libre.org/borrow): Open a loan against BTC collateral - [Lend USDT](https://defi.libre.org/lend): Provide liquidity to lending pools - [Active loans explorer](https://tools.libre.org/loans/mainnet/active): Live on-chain loan data ## For bots and programmatic agents - [Libre for agents](https://www.libre.org/agents/): What an autonomous program can do on Libre — own keys, no trading fees, borrow against BTC — with the commands to verify each claim and a five-step setup. - [Libre MCP server](https://mcp.libre.org): Read market, price, account and loan state, compose unsigned transactions, and relay ones you signed yourself.
