StellarTerm is an open source web app for the Stellar Decentralized Exchange with Ledger Nano S integration.
StellarTerm is a web and desktop app to access the Stellar Decentralized Exchange (Stellar DEX). It's important to note that it is not the Stellar DEX itself; StellarTerm is one of many frontends of the Stellar DEX, whereas the Stellar DEX is the underlying backend.
Please keep in mind that by entering your secret key on a website, you are exposing yourself to the risk of a BlackWallet-esque attack. This is not a problem with StellarTerm specifically, but with web wallets in general. If you input a secret key on any web wallet (which we don't recommend doing), use your hot wallet. StellarTerm offers a Ledger sign in option, which prevents StellarTerm from accessing your secret key.
A former employee of the Stellar Development Foundation - Iris Li - developed StellarTerm, but StellarTerm is independent of the Stellar Development Foundation.
