# Using Clementine

Clementine is Citrea’s trust-minimized Bitcoin bridge. You can use it only at **fixed size**: each deposit moves **10 BTC** from Bitcoin to Citrea (minting **10 cBTC**), and each withdrawal moves **10 cBTC** from Citrea to Bitcoin (paying out approximately **10 BTC**, subject to fees). There are no partial or custom amounts for a single Clementine operation; larger totals require separate 10 BTC (or 10 cBTC) operations.

To learn how the bridge works and read about its security properties, see [Clementine: trust-minimized Bitcoin Bridge](/essentials/clementine-trust-minimized-bitcoin-bridge.md).

If you need to bridge **less than 10 BTC**, use third-party bridges. See [Bridge to Citrea](/welcome/bridge-to-citrea.md) and [citrea.xyz/bridge](https://citrea.xyz/bridge) for options.

If you run into issues with Clementine tooling, email <clementine-cli@citrea.xyz>.

## Clementine Web App

The [Clementine Web App](/essentials/using-clementine/clementine-web-app.md) runs in your browser and walks you through Clementine deposit and withdrawal operations with on-screen steps and status. Use [clementine.citrea.xyz](https://clementine.citrea.xyz) on mainnet and [clementine.testnet.citrea.xyz](https://clementine.testnet.citrea.xyz) on testnet.

## Clementine CLI

The [Clementine CLI](/essentials/using-clementine/clementine-cli.md) is a wallet-agnostic command-line tool for the same 10 BTC / 10 cBTC operations. It suits advanced setups (for example, air-gapped signing and scripting). The CLI docs cover installation, wallet usage, deposit and withdrawal guides, and reproducible builds.
