What Is Stellar (XLM)? The Cross-Border Payments Blockchain Explained for South Africans

What Is Stellar (XLM)?

Stellar is an open-source, decentralised blockchain network that operates as a global payments rail — a piece of financial infrastructure specifically designed to make cross-border money transfers fast, cheap and accessible to everyone, including the billions of people worldwide who remain unbanked or underbanked.

At its core, Stellar acts as a decentralised exchange and clearing layer that allows any two parties to exchange value — whether that is fiat currencies like US dollars, South African rand, or Kenyan shillings, or digital assets — quickly and at minimal cost. Its native cryptocurrency, Lumens (XLM), plays a dual role: it acts as a bridge currency to facilitate the exchange of assets that lack a common direct trading pair, and it is used to pay tiny transaction fees (a fraction of a cent) to prevent spam on the network.

Unlike general-purpose smart contract platforms such as Ethereum or Cardano, which are designed to host entire decentralised application ecosystems, Stellar is highly focused. Its architecture, tooling and governance are all optimised for one job: moving money around the world efficiently. This focus has attracted major institutional adoption, including partnerships with MoneyGram, Wirex and several central banks exploring digital currency issuance on Stellar’s infrastructure.

The Stellar network is overseen by the non-profit Stellar Development Foundation (SDF), which manages the development of the protocol, supports ecosystem grants, and holds a significant portion of the XLM supply to fund adoption initiatives over time.

History: From Ripple to Stellar

Stellar’s origin story is closely intertwined with Ripple (XRP). Jed McCaleb, an American software developer, was a co-founder of Ripple (then called OpenCoin) and the creator of the Mt. Gox Bitcoin exchange. After departing from Ripple in 2013 due to a strategic disagreement about the direction of the project — Ripple was increasingly building a bank-focused, permissioned system — McCaleb teamed up with lawyer and entrepreneur Joyce Kim to create a new, open, non-profit alternative.

Stellar was officially launched in July 2014, initially using a fork of the Ripple protocol. However, after identifying critical reliability and centralisation issues with that codebase, the Stellar Development Foundation rebuilt the network from scratch, launching the Stellar Consensus Protocol (SCP) in 2015. This new consensus mechanism was formally defined and peer-reviewed by David Mazières, a professor of Computer Science at Stanford University — giving Stellar an academically rigorous foundation similar in spirit to Cardano’s peer-reviewed approach.

A defining milestone in Stellar’s history came in 2017, when IBM announced its World Wire payment network, which used Stellar’s blockchain as its underlying settlement layer to enable real-time cross-border payments between major global financial institutions. While IBM later wound down the World Wire product, the partnership demonstrated Stellar’s technical credibility at an enterprise scale and catalysed a wave of institutional interest in the network.

In 2019, the Stellar Development Foundation made a significant and controversial decision to burn approximately 55 billion XLM — more than half of the total token supply that had been held in reserve — to align the supply with actual adoption needs and signal long-term economic discipline to the market.

How Stellar Works — The Stellar Consensus Protocol (SCP)

Stellar does not use Proof of Work (like Bitcoin) or a standard Proof of Stake mechanism (like Ethereum). Instead, it operates on the Stellar Consensus Protocol (SCP) — a novel federated Byzantine Agreement (FBA) system designed by Stanford’s David Mazières.

How SCP Works

In traditional Proof of Work, all miners compete globally to validate each block. In Proof of Stake, validators are selected based on the size of their token deposits. SCP takes a fundamentally different approach through a concept called Federated Byzantine Agreement:

• Each node (validator) on the Stellar network chooses a personal set of other nodes it trusts — called a quorum slice. A node agrees to accept a transaction as valid when enough members of its quorum slice also agree it is valid.
• When quorum slices across the whole network overlap sufficiently, the entire network converges on a single agreed-upon ledger state — this is called reaching quorum.
• Because consensus can be reached through overlapping trust relationships rather than a global competition, Stellar can confirm transactions in 3 to 5 seconds, compared to 10 minutes for Bitcoin and 12 seconds for Ethereum.

Key Technical Advantages of SCP

• Extremely energy-efficient — SCP does not require any computational mining or large token lockups to operate, making Stellar one of the most environmentally friendly blockchains in existence.
• Low transaction fees — Each Stellar transaction costs just 0.00001 XLM (one hundred-thousandth of a Lumen), which at current prices is a fraction of a South African cent — making it economically viable for micro-payments and remittances.
• High throughput — The Stellar network can process approximately 1,000 transactions per second under normal operating conditions, vastly more than Bitcoin (7 TPS) and comparable to traditional card payment networks.
• No slashing or lock-ups — Because SCP does not rely on staked collateral for security, there is no concept of slashing, and users do not need to lock up their XLM to participate in or support the network’s security.

Anchors: The Bridge Between Stellar and the Real World

The most important concept to understand about Stellar’s practical operation is the Anchor system. Anchors are the on- and off-ramps that connect Stellar’s decentralised ledger to the real-world financial system.

An Anchor is a trusted, regulated financial institution or payment processor that accepts deposits of real-world currency (such as ZAR, USD or EUR) from a user and issues a corresponding Stellar-based token (known as a credit) at a 1:1 peg on the Stellar network. That credit can then be sent anywhere in the world in seconds. The recipient can either hold the credit or redeem it at another Anchor for local currency in their country.

How a Real-World Stellar Remittance Works

This four-step process can replace the entire SWIFT-based international wire transfer system — which typically takes 2 to 5 business days and costs 3% to 10% in fees — with a near-instantaneous, near-zero-cost alternative.

Stellar’s Key Use Cases

1. Cross-Border Remittances

This is Stellar’s primary and most impactful use case. By enabling the instant, low-cost transfer of tokenised fiat currencies between Anchors, Stellar dramatically reduces the cost of sending money internationally — a major benefit for migrant workers and their families across Africa, Southeast Asia and Latin America.

2. Stablecoin Issuance and CBDC Infrastructure

Stellar’s fast, cheap and programmable ledger has made it a preferred infrastructure for issuing stablecoins and even central bank digital currencies (CBDCs). Circle’s USDC stablecoin — one of the world’s largest and most regulated dollar-pegged stablecoins — is natively issued on Stellar alongside Ethereum. Several smaller nations and monetary authorities have explored or launched CBDC pilots on Stellar’s infrastructure.

3. Asset Tokenisation

Stellar supports the tokenisation of real-world assets — including equities, bonds, commodities and real estate — on its ledger. Any asset can be represented as a Stellar token, traded on the SDEX, and settled in seconds. This opens the door to fractional ownership of assets that were previously only accessible to wealthy or institutional investors.

4. Financial Inclusion

The Stellar Development Foundation actively funds projects in the developing world aimed at giving unbanked populations access to digital financial services. In Africa specifically, Stellar-powered apps have been deployed to allow users with just a basic smartphone and mobile data connection to send, receive and store value without a traditional bank account.

The Stellar Ecosystem and SDEX

While Stellar’s ecosystem is smaller and more tightly focused than the sprawling DeFi ecosystems of Ethereum or Solana, it contains a well-developed set of infrastructure tools, applications and liquidity providers aligned around its core mission of payments and asset transfer.

Stellar Decentralised Exchange (SDEX)

Unlike Ethereum-based DEXs, which run on separately deployed smart contracts, the Stellar Decentralised Exchange (SDEX) is built directly into the core Stellar protocol itself. This means any token issued on Stellar can be traded against any other Stellar token natively, without needing to interact with external smart contracts. The SDEX uses an order-book model (rather than an AMM liquidity pool) to match buyers and sellers, providing deep, transparent price discovery for all Stellar-based assets.

Key Ecosystem Projects

• Lobstr — The most popular non-custodial Stellar wallet, available on iOS and Android, with a built-in interface for trading on the SDEX and managing Stellar tokens.
• USDC on Stellar — Circle’s USD Coin is natively issued on Stellar, providing a highly liquid, regulated dollar-pegged stablecoin directly accessible on the network for cross-border transfers.
• MoneyGram Access — A partnership between MoneyGram and the Stellar Development Foundation allows users to deposit and withdraw cash in dozens of countries using Stellar’s infrastructure through MoneyGram’s retail network.
• Soroban (Smart Contracts) — Launched in 2024, Soroban is Stellar’s smart contract platform, enabling developers to build more complex DeFi applications directly on Stellar’s high-speed, low-cost ledger using the Rust programming language.

XLM Tokenomics and Supply

Understanding the Lumens (XLM) supply structure is critical for evaluating its long-term investment characteristics.

Stellar originally created 100 billion XLM at genesis. However, in November 2019, the Stellar Development Foundation executed a controlled burn of approximately 55 billion XLM, reducing the total supply to around 50 billion XLM. This burn permanently eliminated tokens that the SDF deemed surplus to its operational needs, demonstrating a commitment to economic discipline and removing a significant potential source of future selling pressure.

As of 2026, the approximate supply breakdown is as follows:

• Circulating Supply — Approximately 28 to 30 billion XLM are in public circulation across exchanges, wallets and deployed applications.
• SDF Operating Fund — The Stellar Development Foundation holds a portion of XLM in a long-term operating fund used to finance core protocol development, ecosystem grants and adoption initiatives. These are released gradually and transparently according to published disbursement plans.

Unlike Cardano (ADA), which has a strictly capped maximum supply of 45 billion, Stellar’s supply model is not technically inflationary — the SDF does not mint new tokens — but large SDF disbursements into the market do represent a source of structural supply pressure that investors should factor into their analysis.

XLM’s Role in the Network

Every Stellar account must maintain a small minimum balance of XLM (currently 1 XLM base reserve) to exist on the network. Each transaction also requires a tiny fee paid in XLM (0.00001 XLM). These two mechanisms ensure XLM has real utility demand baked into the network’s operation, regardless of its speculative price. When XLM is used as a bridge currency on the SDEX to facilitate trades between two tokens with no direct pair, additional demand is generated organically by the payment flow itself.

Stellar vs. Ripple (XRP) vs. Cardano (ADA)

How does Stellar compare to its most directly relevant competitors in the payments and smart contract space?

Stellar and Ripple are often compared because of their shared heritage and similar transaction speeds. The key distinction is philosophical and commercial: Ripple (XRP) targets large banks and financial institutions through a for-profit company model, while Stellar (XLM) targets individuals, NGOs and emerging-market fintech developers through a non-profit foundation model with open, permissionless access. For South Africans and Africans generally, Stellar’s non-profit, open-access model is arguably more aligned with the continent’s financial inclusion goals.

Risks and Investment Considerations

Before investing in Stellar (XLM), it is important to weigh both its genuine strengths and its meaningful risks honestly.

Why Investors Consider XLM

• Clear, proven real-world use case — Unlike many cryptocurrencies that remain primarily speculative, Stellar powers live payment corridors and stablecoin infrastructure (including USDC) with measurable real-world usage today.
• Exceptionally low transaction costs — At fractions of a cent per transaction, XLM has no peer for micropayments and remittances, making it one of the most practically useful cryptocurrencies in daily financial life.
• Non-profit governance — The Stellar Development Foundation’s non-profit status means it is structurally incentivised to build for adoption and impact rather than short-term profit extraction.
• Soroban smart contracts — The 2024 launch of Soroban opens an entirely new category of use cases (DeFi, tokenised assets) on top of Stellar’s already fast and cheap settlement layer.
• USDC and institutional integrations — Stellar’s partnership with Circle (USDC) and MoneyGram gives it a degree of institutional validation that most altcoins lack entirely.

Risks to Keep in Mind

• Large SDF treasury overhang — The Stellar Development Foundation holds billions of XLM that it disburses over time. Each disbursement represents potential selling pressure in the market, which can weigh on price performance.
• Centralisation concerns — SCP’s security relies on trust relationships between validators. In practice, the SDF’s own nodes continue to play an outsized role in network consensus, raising concerns about true decentralisation compared to platforms like Bitcoin or Cardano.
• Narrow DeFi ecosystem — Compared to Ethereum, Solana or even TRON, Stellar’s DeFi and dApp ecosystem remains small, limiting opportunities for users seeking high-yield on-chain financial products.
• Strong competition in remittances — Ripple’s XRP, Toncoin (TON) and even Cosmos (ATOM)-based networks are all competing for the same cross-border payments market that Stellar targets.
• XLM price vs. network usage disconnect — Because XLM transaction fees are so tiny, very high levels of network usage do not necessarily translate into strong upward price pressure on XLM’s market price, making the token’s investment thesis more nuanced than for pure smart contract platforms.
