Stellar
Open network for money — connecting financial institutions and individuals for low-cost cross-border payments.
Overview
Stellar is an open-source, decentralized payment network founded in 2014 by Jed McCaleb, who previously co-founded Ripple and created the Mt. Gox exchange. Originally forked from Ripple's codebase, Stellar quickly diverged with its own consensus mechanism and a fundamentally different mission: rather than focusing on banks and large financial institutions, Stellar aimed to connect the world's financial infrastructure to make money more accessible for everyone, particularly the unbanked populations in developing nations.
Stellar's core value proposition is enabling fast, low-cost cross-border payments. Transactions settle in 3-5 seconds and cost a fraction of a cent, making it one of the most efficient payment networks in existence. The network features a built-in decentralized exchange (SDEX) that allows any tokenized asset to be traded directly on the ledger, enabling seamless currency conversion during cross-border transfers. This means a user in Nigeria can send local currency and have the recipient in the Philippines receive their local currency, with the network handling all intermediate conversions automatically.
Stellar has forged significant real-world partnerships that validate its approach. The partnership with MoneyGram enables cash-in and cash-out through thousands of locations worldwide. Circle chose Stellar as one of the primary networks for USDC, the second-largest stablecoin, recognizing the network's efficiency for dollar-denominated transfers. The Stellar Development Foundation has also been actively involved in central bank digital currency (CBDC) pilots and has worked with governments exploring digital currency infrastructure.
In 2024, Stellar launched Soroban, a smart contract platform built on WebAssembly (Wasm) that brings programmable functionality to the network. Soroban enables developers to build decentralized applications including lending protocols, automated market makers, and complex payment flows directly on Stellar, significantly expanding the network's capabilities beyond simple transfers.
Stellar addresses one of the most tangible problems in global finance: the cost and friction of moving money across borders. With over 1.4 billion adults worldwide lacking access to basic financial services, Stellar's low fees and fast settlement times make it a practical tool for financial inclusion. Its partnerships with regulated entities like MoneyGram and Circle demonstrate that blockchain-based payment infrastructure can integrate with the existing financial system rather than trying to replace it entirely.
How It Works
The Basics
Stellar uses the Stellar Consensus Protocol (SCP), a federated Byzantine agreement mechanism where validators choose which other validators they trust, forming overlapping quorum slices that collectively determine network consensus. Unlike proof-of-work or traditional proof-of-stake, SCP achieves consensus without mining or staking, resulting in extremely low energy consumption and fast finality.
Pros & Cons
- Extremely low transaction fees (fractions of a cent) make micropayments economically viable
- 3-5 second transaction finality enables real-time cross-border payments
- Native USDC support and MoneyGram partnership provide practical fiat on/off ramps
- Soroban smart contracts expand functionality while maintaining network efficiency
- Strong focus on financial inclusion with partnerships in developing economies
- XLM token value accrual is unclear — low fees mean minimal fee revenue for holders
- Smaller DeFi ecosystem compared to Ethereum, Solana, or even Cosmos chains
- Perception as an older project can make it harder to attract new developer talent
- Competition from newer payment-focused chains and Layer 2 solutions is intensifying
- The Stellar Development Foundation holds a significant portion of total supply
Use Cases
- Cross-border remittances with near-instant settlement and negligible fees
- Stablecoin transfers using native USDC on the Stellar network
- Cash-in and cash-out through MoneyGram's global network of physical locations
- Tokenization of real-world assets including foreign currencies and commodities
- Financial inclusion tools for unbanked populations in developing countries
