Stellar (XLM): definition and core purpose
Stellar is an open-source public Layer-1 blockchain designed primarily for fast, low-cost payments, cross-border settlement, asset issuance, and financial applications. Its native asset is the lumen, XLM.
Unlike general-purpose networks that began with decentralized computing or digital scarcity as their primary objectives, Stellar was designed around moving value between currencies and financial systems. The network can transfer XLM, stablecoins, fiat-backed tokens, tokenized securities, and other issued assets. XLM is used to pay transaction fees, satisfy minimum account-balance requirements, and sometimes provide liquidity or act as a bridge asset between different currencies.
Stellar’s value proposition is therefore broader than simply transferring XLM. It provides a public settlement layer where financial institutions, fintech companies, developers, and users can issue, exchange, and move multiple forms of digital value.
Core technology and blockchain architecture
Multi-asset ledger
The Stellar ledger records:
- Account balances and trust relationships.
- XLM and issuer-backed assets.
- Offers on the network’s built-in decentralized exchange.
- Path-payment routes between different assets.
- Smart-contract data associated with Soroban.
- Authorization, clawback, and other controls for certain regulated assets.
Any eligible issuer can create a custom asset on Stellar. These assets may represent fiat currencies, stablecoins, securities, commodities, funds, or other claims. The underlying blockchain records ownership and transfers, while the issuer or anchor remains responsible for backing, redemption, and compliance.
Built-in decentralized exchange and path payments
Stellar includes an order-book-based decentralized exchange at the protocol level. Users can place offers to buy or sell assets, and path payments can automatically route a transaction through available liquidity.
For example, a payment sent in one asset may be received in another if a suitable conversion path exists. This design is particularly relevant to cross-border payments because the sender and recipient do not necessarily need to hold the same currency or token.
Anchors and financial gateways
Stellar uses the term “anchor” for organizations that connect blockchain assets to traditional financial systems. Anchors may:
- Accept fiat deposits and issue corresponding digital assets.
- Redeem digital assets for local currency.
- Connect wallets to banks, payment systems, or cash networks.
- Provide local on-ramps and off-ramps.
- Support compliance and transaction-monitoring processes.
This architecture allows Stellar to handle digital settlement while regulated or trusted financial partners handle cash conversion and local payment access.
Smart contracts through Soroban
Historically, Stellar concentrated on payments and asset issuance. Soroban, its WebAssembly-based smart-contract platform, expanded the network into programmable applications, including:
- Lending and borrowing.
- Automated market makers and decentralized exchanges.
- Smart wallets and account abstraction.
- Tokenized securities and fund administration.
- Asset management.
- Payment routing.
- Compliance-aware financial contracts.
- Other decentralized finance applications.
Soroban uses WebAssembly-related tooling and supports Rust-oriented development. It was introduced to the public network through Protocol 20 in 2024, allowing Stellar to compete more directly with general-purpose smart-contract platforms while retaining its payments-focused architecture.
Consensus mechanism: the Stellar Consensus Protocol
Federated Byzantine agreement
Stellar does not use mining-based Proof of Work, as used by Bitcoin, and it does not use stake-weighted Proof of Stake, as used by Ethereum. Instead, it uses the Stellar Consensus Protocol, or SCP.
SCP is a form of Federated Byzantine Agreement. Each validator independently chooses which other validators it trusts. These selections are organized into quorum sets and quorum slices:
| Concept | Meaning | |
|---|---|---|
| Quorum set | The validators a node chooses to trust, together with the required voting threshold | |
| Quorum slice | A sufficient subset of trusted validators needed to satisfy that node’s threshold | |
| Quorum | A group of nodes in which every member contains a qualifying quorum slice | |
| Blocking set | A group whose disagreement or absence can prevent a node from reaching agreement |
Consensus emerges when enough overlapping trust relationships cause validators to agree on the same transaction set and ledger state.
How an SCP round works
An SCP consensus round generally involves:
- Nomination: Validators propose transaction sets for inclusion.
- Balloting: Validators vote on the proposed transaction set.
- Confirmation: A sufficiently connected quorum accepts the result.
- Ledger application: Nodes apply the agreed transactions and update their state.
Once a ledger has been confirmed under a functioning quorum, transactions are treated as finalized rather than waiting for additional mined blocks. Stellar is designed to settle transactions in seconds. Official materials cite sub-six-second settlement in some contexts, while other network measurements have reported approximately 9.5 seconds.
Security trade-offs
SCP prioritizes safety and fault tolerance over liveness. If validators cannot establish a sufficiently safe agreement, the network may temporarily stop advancing rather than confirm conflicting ledger states.
This produces an important trade-off:
- Advantage: Fast, energy-efficient settlement without mining or staking.
- Risk: Network safety and availability depend on validator diversity, reliability, and quorum configuration.
Anyone can operate a Stellar Core node, but a node only influences consensus if other validators include it in their quorum sets. Security can weaken if many validators rely on the same small group of related organizations, infrastructure providers, or operators. Conversely, sufficiently diverse and overlapping quorum relationships improve resilience.
Stellar validators do not receive protocol-level monetary rewards for validating transactions. Organizations typically operate validators because they depend on the network, support its ecosystem, or want to contribute to its reliability. This differs from networks where block rewards or staking yields provide direct economic incentives for validation.
Stellar compared with Bitcoin, Ethereum, and XRP Ledger
| Network | Consensus model | Primary design emphasis | Native-asset role | |
|---|---|---|---|---|
| Bitcoin | Proof of Work | Scarcity, censorship-resistant settlement, and digital value | Primarily a scarce digital commodity and settlement asset | |
| Ethereum | Proof of Stake | General-purpose smart contracts and decentralized applications | Used for fees, settlement, and application activity | |
| Stellar | Federated Byzantine Agreement through SCP | Payments, asset issuance, cross-border settlement, and financial infrastructure | Used for fees, minimum balances, liquidity, and some bridge-payment functions | |
| XRP Ledger | Federated validator consensus | Payments, issued assets, and exchange functionality | XRP can provide liquidity, although Ripple’s enterprise products do not necessarily require it for every payment |
Stellar and the XRP Ledger are both designed for rapid, low-cost settlement, but their institutional structures differ. Stellar is an open public network supported by the nonprofit Stellar Development Foundation. Ripple’s payment business is more company-led and institution-focused, and its commercial products should not be treated as identical to the XRP Ledger or XRP itself.
Stellar also emphasizes stablecoin cash access, regulated asset issuance, and financial inclusion. Its applications can use USDC, EURC, tokenized funds, or other issued assets, so XLM is not necessarily the settlement asset in every transaction.
Primary use cases
Cross-border payments
Stellar’s central use case is moving value across currencies and jurisdictions. Payment providers can use tokenized fiat or stablecoins to settle transactions continuously rather than relying solely on banking-hour processes and correspondent-bank networks.
Potential benefits include:
- Faster settlement.
- Lower transaction costs.
- Fewer intermediaries.
- Multi-currency account functionality.
- Easier connectivity between local payment systems.
- Around-the-clock transfer and settlement.
The practical result depends on the availability of liquidity, local payment partners, regulatory permissions, and reliable fiat conversion.
Remittances
Remittance providers can use Stellar-based stablecoins and local anchors to create a flow such as:
- A sender deposits local currency.
- The provider converts it into a digital dollar or another supported asset.
- The asset moves across Stellar.
- The recipient redeems it for local currency or spends it digitally.
This may reduce the number of intermediaries involved, but the recipient still needs access to an appropriate wallet, cash-out partner, and local liquidity.
Stablecoins and payment rails
Stellar supports major fiat-backed assets, including USDC and EURC, issued through Circle. Stellar’s own materials describe these assets as suitable for payments, remittances, exchange settlement, treasury transfers, and dollar- or euro-denominated accounts.
Stellar-reported USDC metrics include:
- More than 4.5 million total payments.
- More than $3 billion in total payment volume.
These figures are platform-reported measurements, so their methodology and scope should be considered when comparing them with metrics from other networks.
MoneyGram cash conversion
MoneyGram partnered with Stellar and Circle in 2021, later launching crypto-to-cash services in selected markets in 2022. The arrangement allows users of compatible wallets to convert cash into USDC or redeem USDC for local currency through participating MoneyGram locations.
In April 2026, MoneyGram and the Stellar Development Foundation announced a multiyear partnership extension. The initiative included a stablecoin balance in the MoneyGram app, initially launched in Colombia, with plans to expand stablecoin utility across Latin America. The companies stated that MoneyGram’s network covered more than 200 countries and territories and nearly 500,000 retail locations.
A separate June 2026 report described MGUSD, a dollar stablecoin on Stellar backed by Bridge and Fireblocks, targeting more than 60 million customers. The available research does not establish that MGUSD replaced USDC across MoneyGram’s broader network.
Asset tokenization
Stellar is increasingly positioned as infrastructure for tokenized real-world assets, including:
- Government securities and treasury instruments.
- Money-market funds.
- Commodities.
- Fiat currencies.
- Stablecoins.
- Other regulated financial products.
Franklin Templeton launched the BENJI tokenized money-market fund on Stellar in April 2021. Franklin Templeton later used its Benji platform for a tokenized UCITS fund in Luxembourg in 2024 and a retail tokenized fund in Singapore in 2025. BENJI is also available to U.S. retail users through the Benji Investments mobile application.
WisdomTree has also used Stellar-based infrastructure for digital funds offered through WisdomTree Prime. These integrations demonstrate that Stellar’s proposition extends beyond inexpensive payments to programmable ownership records, continuous availability, and settlement of regulated financial products on a public blockchain.
Humanitarian aid and financial inclusion
Stellar-based payment systems have been used for aid distribution and financial-access initiatives. One example is UNHCR Stellar Aid Assist in Ukraine, which uses digital payments for humanitarian assistance.
These systems can improve speed and traceability, but their success still depends on recipients having suitable wallets, connectivity, local support, and practical cash-out options.
Decentralized finance and programmable finance
Soroban allows Stellar to support more complex financial applications, such as lending, automated market makers, smart wallets, and tokenized-asset management. This gives the network a broader addressable market than its original payment-only focus.
However, Soroban’s long-term success depends on building enough independent applications, developers, liquidity, and users to complement Stellar’s established payments infrastructure.
Founding team and project history
Founders and early contributors
Stellar was founded in 2014. Its early leadership included:
| Person | Role and contribution | |
|---|---|---|
| Jed McCaleb | Co-founder and original CTO; provided technical and strategic direction | |
| Joyce Kim | Co-founder and early executive director of the Stellar Development Foundation | |
| David Mazières | Co-founder and chief scientist; architect of SCP | |
| Nicolas Barry | Early CTO and lead engineer for stellar-core and the production implementation of SCP |
Jed McCaleb previously founded the eDonkey peer-to-peer file-sharing network, founded Mt. Gox before its later collapse under different ownership, and co-founded the company that became Ripple Labs. He left Ripple in 2013 following disagreements about the project’s direction. Stellar was created in 2014 partly in response to perceived gaps in existing global financial infrastructure.
David Mazières is a Stanford computer science professor specializing in operating systems, security, and distributed systems. His academic background shaped the design of SCP and gave Stellar’s consensus system a formal distributed-systems foundation.
Joyce Kim helped establish the foundation’s early operations and strategy before leaving Stellar in its early years. Nicolas Barry contributed to the implementation of Stellar Core, the reference software responsible for participating in the network’s peer-to-peer payment and consensus processes.
Stripe provided initial funding to help launch the foundation and network.
Leadership evolution
The foundation’s leadership evolved from a technically focused founding group into a more institutionally oriented organization.
Denelle Dixon became CEO and executive director in 2018. Before joining Stellar, Dixon spent approximately six years at Mozilla, eventually serving as chief operating officer and corporate secretary. She had previously held legal, business, strategy, and public-policy roles at Mozilla, Yahoo!, and Terra Firma.
Under Dixon, the Stellar Development Foundation placed greater emphasis on:
- Institutional partnerships.
- Regulatory engagement.
- Enterprise and government adoption.
- Stablecoins and payment infrastructure.
- Real-world asset tokenization.
- A more formal corporate and policy structure.
The contemporary executive organization includes leaders such as Jose Fernandez da Ponte, a former PayPal blockchain and digital-currency executive; Raja Chakravorti, with experience at Goldman Sachs, JPMorgan, PayPal, and Plaid; Candace Kelly, who leads legal and policy activities; and Lisa Wagner Macnew, who oversees people and organizational functions. David Mazières remains chief scientist, providing continuity with the original technical design.
Research estimates place the Stellar Development Foundation’s workforce at approximately 200 to 300 people across 26 countries, although staffing figures can change and should be treated as approximate.
XLM tokenomics
Supply and market profile
The market data provided for September 1, 2026 reports the following:
| Metric | Reported figure | |
|---|---|---|
| Price | $0.1785 | |
| Market capitalization | $6.19 billion | |
| Market-capitalization rank | 24 | |
| 24-hour trading volume | $141.68 million | |
| Circulating supply | 34.69 billion XLM | |
| Total supply | Approximately 50.00 billion XLM | |
| Fully diluted valuation | $8.92 billion | |
| Market-data risk score | 44.08 | |
| Liquidity score | 54.08 | |
| Volatility score | 7.63 |
The same data reports total supply of approximately 50,001,786,840 XLM, effectively matching the current supply cap. About 34.69 billion XLM were reported as circulating, leaving a significant quantity outside circulation, generally in foundation-controlled or otherwise undistributed reserves.
Historical supply policy
Stellar originally launched with 100 billion units and an annual inflation plan of 1%. That original inflation mechanism was removed in 2019.
In November 2019, the Stellar Development Foundation burned more than half of the original supply, reducing the total from roughly 105 billion to approximately 50 billion XLM. This was a major tokenomics change and materially reduced the maximum supply.
Historical distribution categories included:
- Network development and ecosystem funding.
- Direct user-distribution programs.
- Institutional and partnership allocations.
- Foundation-controlled reserves.
The foundation has periodically adjusted reserve policies and distribution strategies. The exact allocation of remaining non-circulating supply can change over time, so circulating-supply data and official foundation disclosures should be checked when assessing dilution or distribution risk.
Inflation and deflation mechanics
Current XLM supply mechanics are:
- No ongoing protocol-level inflation.
- Approximately 50 billion maximum and total supply.
- Very small transaction fees.
- Fees are burned rather than paid as validator rewards.
The fee burn creates a technically deflationary effect, but transaction fees are so small that the burn is not expected to materially reduce supply over short periods. XLM is therefore best characterized as fixed-supply rather than meaningfully deflationary.
Historical price extremes
Reported price extremes are:
- All-time high: approximately $0.9381 on January 4, 2018.
- All-time low: approximately $0.001227 on March 5, 2015.
The one-year data provided shows:
- Price on September 2, 2025: $0.3645.
- One-year peak on September 13, 2025: $0.4075.
- Price on September 1, 2026: approximately $0.1783 to $0.1785.
This indicates a substantial decline over the period, with an early rally followed by a prolonged downtrend and consolidation. Market price is not necessarily a direct measure of network usage because Stellar activity can be denominated in stablecoins and other issued assets rather than XLM.
Major partnerships and ecosystem integrations
| Partner or integration | Role in the Stellar ecosystem | Status or context | |
|---|---|---|---|
| MoneyGram | Cash-to-stablecoin and stablecoin-to-cash conversion, remittances, and payment access | Partnership extended for multiple years in April 2026 | |
| Circle | Issuer and infrastructure provider for USDC and EURC on Stellar | USDC support announced in 2020 | |
| Franklin Templeton | BENJI tokenized money-market fund and additional tokenized funds | Stellar deployment began in 2021, with later expansion to Luxembourg and Singapore | |
| WisdomTree | Digital funds and tokenized investment products | Uses Stellar-based infrastructure for selected digital funds | |
| PayPal | Planned PYUSD availability on Stellar | Announced June 2025, subject to regulatory approval | |
| IBM World Wire | Historical institutional payment network built on Stellar | Announced in 2018, initially described as covering 47 currencies in 72 countries | |
| United Nations Development Programme | Digital-payment and financial-inclusion initiatives | Extended partnership announced in May 2026 | |
| UNHCR | Humanitarian aid disbursement through Stellar Aid Assist | Example of blockchain-based aid delivery |
Partnerships should be interpreted carefully. A company’s use of Stellar infrastructure does not necessarily mean that XLM is the asset used for every transaction. Many applications rely primarily on USDC, tokenized funds, or other issued assets, while XLM remains necessary for network fees, minimum balances, and certain liquidity functions.
Development activity and roadmap
Protocol 20 and Soroban mainnet
On February 20, 2024, validators voted to upgrade the Stellar mainnet to Protocol 20, introducing Soroban smart-contract functionality. The rollout was phased, and general building, deployment, and interaction on mainnet opened on March 19, 2024.
Protocol 21
Validators approved Protocol 21 on June 18, 2024. The upgrade activated five Core Advancement Proposals and continued Stellar’s transition toward a broader programmable-finance platform.
Protocol 22 and Stellar RPC
Soroban RPC was renamed Stellar RPC as the service expanded beyond smart-contract data to cover the broader Stellar network. The objective was to provide a more unified interface for assets, classic transactions, contracts, and related events.
This matters for wallets, exchanges, block explorers, compliance providers, and institutional applications because reliable indexing and data access reduce development complexity.
Protocol 23, “Whisk”
Protocol 23 went live on September 3, 2025. Its main changes included:
- Parallel transaction execution.
- Greater read capacity for Soroban state.
- Lower Soroban costs through improved memory handling.
- WebAssembly module caching.
- Less manual restoration of archived entries.
- New host functions for contract executable retrieval and string or byte conversion.
- SEP-0041 token-interface events for operations that move value across the network.
The upgrade was aimed at improving execution capacity, storage efficiency, developer experience, and visibility into asset movements.
The 2025 roadmap also identified a theoretical target of 5,000 transactions per second through concurrency, caching, and ahead-of-time compilation. This is a development target or theoretical capacity objective, not evidence that the network continuously processes 5,000 transactions per second in production.
Protocol 24, Protocol 25, and later upgrades
Protocol 24 was described as a stability upgrade intended to correct a bug in Stellar Core’s state-archival feature.
Protocol 25, called “X-Ray,” was announced in November 2025 and scheduled for a January 22, 2026 mainnet vote. It introduced groundwork for configurable, compliance-compatible privacy through technologies including:
- BN254, a pairing-friendly elliptic curve.
- Poseidon hash functions designed for zero-knowledge-proof systems.
These components may support future privacy and compliance applications, but they do not mean that Stellar transactions became confidential by default.
Official Stellar materials also list Protocol 26, “Yardstick,” and Protocol 28, “Adapter,” as part of the 2026 upgrade cycle. The available research confirms their inclusion in the active upgrade program but does not provide enough verified technical detail to describe every feature accurately.
Developer funding and ecosystem growth
The Stellar Development Foundation created a $100 million Soroban adoption fund. The Stellar Community Fund also offers awards for Stellar and Soroban projects, with qualified submissions potentially receiving up to $150,000 worth of XLM per award.
Official Stellar materials indexed by August 2026 included:
- 41 Soroban-related posts.
- 29 smart-contract posts.
- 23 developer posts.
These counts indicate sustained official development and communication activity, but they are not equivalent to independent measurements of active developers, deployed applications, or production users.
Validator resilience
SDF’s 2025 roadmap included a “2x Tier 1 Resilience” objective. In a July 2025 update, SDF stated that seven Tier 1 organizations then allowed the network to remain operational despite two failures, with a plan to add six more and reach 13 by the end of 2025.
The initiative is important because validator diversity is central to SCP’s security model. Increasing the number of independent, operationally significant validators can reduce dependence on a small group of highly influential nodes.
Competitive advantages
Stellar’s principal strengths are:
- Payments-first architecture: Asset issuance, path payments, order-book exchange functionality, and settlement are integrated into the base protocol.
- Fast and inexpensive transfers: The network is designed for frequent, low-value, and cross-border transactions.
- Stablecoin and fiat connectivity: Anchors and partnerships such as MoneyGram provide practical links between on-chain assets and local currencies.
- Institutional tokenization: Franklin Templeton and WisdomTree provide concrete examples of regulated financial products using Stellar infrastructure.
- Open public infrastructure: Independent developers and institutions can build on a common public ledger rather than using only a private payment network.
- Compliance-oriented features: Issuers can use authorization, clawback, and approval controls where appropriate for regulated assets.
- Smart-contract expansion: Soroban broadens Stellar into programmable finance without abandoning its payment and asset-settlement foundation.
- Energy efficiency: SCP does not require Proof-of-Work mining.
Key limitations and risks
Stellar also faces structural challenges:
- Validator concentration: SCP depends on diverse and sufficiently overlapping quorum relationships.
- Liveness trade-off: The network may halt temporarily if validators cannot safely agree.
- Issuer and anchor dependence: A tokenized dollar or security is only as reliable as its issuer, backing, redemption process, and compliance framework.
- XLM value capture: Ecosystem growth may occur through USDC, EURC, tokenized funds, or other assets rather than through direct demand for XLM.
- Soroban competition: Stellar must compete with larger smart-contract ecosystems for developers, liquidity, applications, and users.
- Partnership execution: Announced partnerships and planned integrations do not automatically translate into large-scale, sustained usage.
- Foundation influence: The Stellar Development Foundation remains highly influential in ecosystem funding, development, partnerships, and distribution strategy.
Overall assessment
Stellar is a payments-oriented blockchain whose distinctive features are its federated consensus model, native multi-asset support, built-in exchange functionality, stablecoin and fiat connectivity, and growing smart-contract layer.
Its development has progressed through several phases:
- 2014 to 2015: Launch of the network and formalization of SCP.
- 2017 to 2021: Expansion of anchors, payment integrations, asset issuance, and stablecoin infrastructure.
- 2019: Major supply reduction from roughly 105 billion to approximately 50 billion XLM.
- 2021 onward: Institutional tokenization through products such as Franklin Templeton’s BENJI.
- 2022 to 2024: Development and mainnet introduction of Soroban.
- 2025 to 2026: Improvements to execution capacity, RPC infrastructure, validator resilience, privacy technology, stablecoin connectivity, and protocol performance.
The strongest evidence of Stellar’s real-world positioning is concentrated in stablecoin settlement, cash-access networks, cross-border payments, and tokenized financial products. Soroban gives the network a path into decentralized and programmable finance, although its future competitive standing will depend on sustained application growth, independent developer participation, liquidity, user adoption, and continued improvement in validator diversity.
