This week, Stellar finally launched its long-awaited decentralized exchange, Stellarx. The platform enables trading of assets from multiple blockchains, including Bitcoin, Ethereum, and more, using Stellar Lumens (XLM) as the base currency. Unlike existing DEXs that are limited to tokens on a single blockchain—usually Ethereum—Stellarx offers BCH, BTC, USD, ETH, and other assets. However, non-native assets are represented as 'tethers,' tokenized representations tied to the underlying asset.
Backdrop and Controversy: Stellar's Centralization Paradox
Stellar was founded by Jed McCaleb as a fork of Ripple, and its decentralization credentials have been questioned. According to Are We Decentralized Yet?, XLM scores low on multiple metrics: the top 100 accounts hold 95% of the total supply, there is only one client codebase controlling nodes, and only 111 public nodes are operational. Yet this heavily centralized cryptocurrency project has produced one of the most innovative and user-friendly DEXs seen to date.
How Stellarx Works
Stellarx operates as a true DEX should: users retain sole custody of funds, trades are executed peer-to-peer, and the platform cannot access funds. It allows trading of non-native crypto assets such as BTC and BCH, plus fiat currency deposits, making it far more feature-rich than bare-bones DEXs like IDEX or Forkdelta.
Registration only requires an email and password—no additional verification needed. Users create a private key for their Stellar wallet and note the recovery phrase. The trading interface is accompanied by a walkthrough and is far sleeker than any rival DEX has produced. Cross-chain asset trading is made possible through 'tethers': tokens issued on Stellar that represent assets from other blockchains. For example, when you buy Bitcoin on Stellarx, you actually buy a Stellar-issued token that represents Bitcoin. Tethers are categorized as 'fiat tethers,' 'crypto tethers,' or 'native tokens.'
Key Features: Zero Fees and Human-Readable Addresses
Stellarx boasts zero trading fees and offers human-readable wallet addresses in the format 'yourname@stellarx.com.' Users who prefer privacy can use a non-identifiable public key instead. Assets can be filtered by volume, price, name, issuer, and other variables. The platform accepts fiat deposits via Anchorusd.com, which requires KYC—a rare feature for a DEX.
For withdrawals, users can send to another Stellar address or an off-chain account. For tethered assets like BTC, they must visit the issuer's website (e.g., Naobtc) to convert the token to real BTC. Stellarx plans to integrate off-chain withdrawals within the app later to simplify the process.
Assessment and Outlook
While Stellarx still needs to improve liquidity, add more assets, and onboard sufficient users, its initial offering is impressive. Cross-chain trading, zero fees, fiat on-ramp, and intuitive interface make it a welcome addition to the decentralized exchange ecosystem. It demonstrates how DEXs can achieve centralized exchange convenience without sacrificing security.
