## What it is
btcwallet is a secure hierarchical deterministic (HD) bitcoin wallet daemon written in Go. It acts as an RPC client to a btcd full node and serves wallet clients via a legacy JSON-RPC server or an experimental gRPC server.

## Use cases
- run a bitcoin wallet daemon backed by a btcd full node
- manage HD bitcoin wallets with BIP32/BIP44 key derivation
- build wallet applications that talk to bitcoin over RPC or gRPC
- encrypt wallet public data for privacy
- migrate wallet apps from Bitcoin Core's JSON-RPC API

## When to choose
- you need a programmatic bitcoin wallet daemon in Go
- you already run btcd and want wallet functionality on top
- you want encrypted private keys and optional public-data encryption
- you need Bitcoin Core-compatible JSON-RPC or a gRPC wallet API

## When to avoid
- you want a lightweight SPV wallet without a full node
- you need a graphical wallet for end users
- you want a stable, finalized gRPC API
- you need multi-user or custodial wallet infrastructure
