Quick Verdict
Stellar (XLM) has a relatively strong case for permissibility among cryptocurrencies. Like XRP, Stellar's primary purpose is international payment facilitation — a legitimate commercial activity in Islam. The Stellar Development Foundation's mission (financial inclusion for the unbanked) also aligns well with Islamic values of economic justice.
Stellar's Mission and Muslim Values
Stellar was designed to connect people globally to low-cost financial services. It's used for remittances from the US to Africa, micropayments, and cross-border trade settlements. Providing affordable financial services to underserved communities is consistent with Islamic principles of fairness (adl) and social welfare (maslaha).
Technical Simplicity
Like Litecoin, Stellar focuses on payments rather than DeFi. While Stellar does support tokens and some smart contract functionality, the ecosystem is much less dominated by speculative DeFi applications than Ethereum or Solana. XLM transactions don't involve lending at interest.
Concerns
The Stellar Development Foundation controls a large supply of XLM, which is gradually distributed. This centralization is somewhat unusual for crypto and some scholars might view it as a concern for transparency. Most XLM trading is still speculative rather than for actual remittance purposes.
Bottom Line
Stellar has a stronger halal case than DeFi-platform tokens due to its payment focus and financial inclusion mission. Classify as doubtful (with the honest acknowledgment that most retail holders are speculating) but with a leaning toward permissible if held as a payment utility.
