## What it is
A repository of SatoshiLabs Improvement Proposals (SLIPs), technical specification documents extending the Bitcoin Improvement Proposal (BIP) process for features outside Bitcoin's scope. It covers standards like universal private key derivation, symmetric key hierarchies, and wallet formats used by Trezor and other cryptocurrency projects.

## Use cases
- understand how SLIP-0010 universal private key derivation works
- find the specification for hierarchical symmetric key derivation
- implement HD wallet key derivation for Cardano or other altcoins
- look up the Trezor payment request format
- propose a new standard for hardware wallet features
- reference FIDO2 credential ID format for HD wallets

## When to choose
- you need authoritative specifications for SLIP standards like key derivation or encryption formats
- you are implementing wallet software compatible with Trezor or SatoshiLabs projects
- you want to propose or review technical standards extending the BIP process

## When to avoid
- you need executable code or software libraries rather than specification documents
- you are looking for BIPs that belong in the official Bitcoin BIP repository
- you need general Bitcoin documentation unrelated to SatoshiLabs standards

## Facets
- artifact type: learning-resource
- maturity: active
- function: documentation, cryptography, security
- domain: security, documentation, developer-tools
- platform: cross-platform
- tags: bip, slip, hd-wallets, specifications, trezor, key-derivation, bitcoin, standards, cryptocurrency
