# How to Create a Profile on Tapestry: A Developer's Guide

### Build decentralized social applications on Solana faster with Tapestry's composable social protocol

Profiles on [Tapestry](/content/site-root.html) provide a flexible identity management system for modern applications, built on Solana's high-performance blockchain. As a decentralized social protocol, Tapestry provides the foundational infrastructure for applications that prioritize user sovereignty and data portability, enabling developers to create social experiences where users truly own their data and social connections across the ecosystem.

This guide walks through profile setup, API integration, and implementation best practices.

# How Do Profiles Work on Tapestry?

A profile on Tapestry serves as a composable identity primitive that developers can customize based on their application's needs. Each profile operates within its own application, but can interoperate with other apps on the protocol.

## Core Components

Every profile on Tapestry includes customizable fields for storing user information:
- Username and basic identification
- User biography and personal details
- Profile imagery and media assets
- Application-specific preferences
- Connected applications and services

Additionally, custom properties can be passed into a profile. For example, the user’s favorite color or position on waitlist.

## Profile Architecture

Profiles are designed with two key architectural principles:
1. **Sovereignty:** Users own their profiles as assets that their wallet controls.
2. **Namespaces**: Each profile is assigned to a given namespace, but can interoperate with other apps on the protocol. In the same way tokens stay in your wallet, but can be accessed by many apps, so too can profiles.
