# Introduction

## The TalentLayer TLDR

TalentLayer **is a protocol for building decentralized service marketplace applications** like Uber, Postmates, Rappi, and others.

TalentLayer can help you build new marketplaces - with the protocol replacing key backend components, helping you go to market faster.

**Why leverage a protocol for your marketplace app?** Tap into a unified network effect; many interfaces have access to one pool of users, offers, and products. This increases efficiency of supply and demand matching, and helps marketplaces overcome the chicken and egg problem.

**TalentLayer's Web 3 API and SDK** is live and available for integration. The Web 3 API and SDK assumes a web 3 native user experience on the platform level. Account delegation and gassless are enabled today so that platform developers can implement account abstraction optionally.
