# UMA Test Wallet

> Test UMA payment flows with a real counterparty

Grid provides an UMA Test Wallet to help you test UMA payment flows with a real counterparty.

The UMA Test Wallet is an external tool that demonstrates UMA payment flows end to end and gives you a realistic counterparty for development and QA. It helps you understand flows through hands-on interaction, explore recommended UX patterns, and develop against a live UMA FI.
