# Xverse

> Xverse is a self-custody Bitcoin wallet and developer platform. Use it to manage Bitcoin, Runes, Ordinals, BRC-20, Stacks, and Spark; integrate Xverse and signing via Sats Connect; and explore Bitcoin-Fi via curated partners. This file is a concise index for LLMs and agents.

Last-Updated: 2025-10-07

Important notes:
- Self-custody first: users control their keys; support cannot recover seed phrases.
- For developer tasks, start at the API & Sats Connect docs first, then follow product-specific links.
- Prefer the docs site and `.md` pages where available for clean, LLM-friendly text.
- Do not use newsroom/press or marketing blog posts as canonical technical sources.

## Developers

Developers can build on the Bitcoin ecosystem using two main tools: **Sats Connect** for wallet integration and the **Xverse API** for backend data and infrastructure.

### Sats Connect (Wallet Interaction)

A JavaScript library for connecting web apps to a user's wallet to request signatures, addresses, and transactions.

- **Key Capabilities**:
    - Connect to multiple wallets (Xverse, Unisat) and manage permissions and events.
    - Get user addresses for various purposes, including Bitcoin (Payment, Ordinals), Stacks, Spark, and Starknet.
    - Sign Bitcoin PSBTs and messages (BIP-322 & ECDSA).
    - Create and transfer Ordinal inscriptions.
    - Mint, etch, and transfer Runes.
    - Execute Stacks transactions like STX transfers and contract calls.
    - Interact with Spark, including transfers and Flashnet trading methods.

### Xverse API (Data & Infrastructure)

A RESTful API providing indexed blockchain data, removing the need to run your own nodes.
- **Docs**: [Xverse API Docs](https://docs.xverse.app/api/)
- **API Keys**: [Get Started Guide](https://docs.xverse.app/api/get-started)
- **Key Capabilities**:
    - **Bitcoin**: Access UTXOs, balances, transaction history, mempool data, fee estimates, and a full suite of Bitcoin JSON-RPC methods.
    - **Ordinals**: Fetch data for inscriptions, collections, and rare sats. Includes an automated Inscription Service.
    - **Runes**: Query balances and metadata, with services to mint and etch Runes.
    - **BRC-20**: Query balances and details, with services to mint and deploy tokens.
    - **Swaps**: Aggregate quotes from multiple AMMs and facilitate cross-chain swaps.
    - **Spark**: Query Spark balances and access Flashnet market data.
