What is Stellar?
Stellar is a public, open-source blockchain designed for one core job: moving value — dollars, euros, stablecoins, tokenized assets — quickly and cheaply between people and institutions. Its native token is the lumen (XLM). Unlike a general-purpose chain that markets itself on running any app, Stellar was purpose-built around payments, currency conversion, and asset issuance.
It launched on July 31, 2014, created by Jed McCaleb (who earlier co-founded Ripple and, before that, built the Mt. Gox exchange) together with Joyce Kim. It's stewarded by the Stellar Development Foundation (SDF), a US-based nonprofit that got an early $3 million loan from Stripe. The nonprofit framing is central to Stellar's pitch: it positions itself as public financial infrastructure rather than a company chasing profit.
The network began as a fork of the Ripple protocol, but after an early consensus problem it switched in 2015 to its own design, the Stellar Consensus Protocol (designed by Stanford's David Mazières). The stated mission has stayed consistent: expand access to low-cost financial services, especially for cross-border payments and remittances where fees and delays hit hardest.
In practice, Stellar today is best understood as a settlement rail for stablecoins and tokenized real-world assets. Much of the meaningful activity on it isn't XLM trading — it's USDC, PayPal's PYUSD, and tokenized funds moving between wallets and off-ramps.
How it works
Stellar doesn't use mining (proof-of-work) or staking (proof-of-stake). It runs the Stellar Consensus Protocol (SCP), a form of Federated Byzantine Agreement. In plain terms: each validator picks a set of other participants it trusts (its 'quorum slice'). Consensus emerges from these overlapping circles of trust agreeing on the ledger, instead of from whoever burns the most electricity or stakes the most coins.
The upside is speed and near-zero energy use — a new ledger closes in roughly 5 seconds and fees are a tiny fraction of a cent. The trade-off is that security depends on how validators choose who to trust, and in practice a relatively small set of well-run validators (including SDF's) carries much of the network. That's a genuine design tension, not just a talking point.
XLM itself plays a supporting role rather than being the star. It pays the tiny transaction fees, acts as a bridge asset when converting between currencies, and enforces a small minimum balance (a few XLM) on each account to prevent spam and bloat. Stellar also has a built-in decentralized exchange and native asset-issuance, so anyone can mint a token or stablecoin directly on the protocol without deploying a contract.
Consensus: Stellar Consensus Protocol (SCP) — Federated Byzantine Agreement, no mining or staking
Speed & cost: ledgers close in ~5 seconds; fees are fractions of a cent
Energy: negligible compared to proof-of-work chains
XLM's job: pays fees, bridges currencies, and funds a small anti-spam minimum balance per account
Smart contracts: Soroban, a Rust/WebAssembly contract platform (live on mainnet since Feb 2024), added to support DeFi and tokenization
What they're building
Stellar's current direction is dominated by two threads: scaling the base layer and maturing its Soroban smart-contract platform. The SDF's headline scaling goal, framed as the 'road to 5000 TPS', is pushing Stellar Core's throughput up dramatically through concurrency, caching, and ahead-of-time compilation of Soroban contracts, while cutting ledger close times toward ~2.5 seconds.
This is being delivered through a steady cadence of protocol upgrades. Recent versions brought multi-threaded smart-contract execution and caching to raise throughput. As of early July 2026, Protocol 27 — code-named 'Zipper' — is up for a mainnet validator vote around July 8, 2026; its headline features are native authentication delegation and smart accounts (letting one account authorize another to sign for it, which unlocks social recovery and modular multisig) plus a security fix for a Soroban signature-replay gap. Alongside this, the foundation is shipping standardized token contracts (for fungible tokens, NFTs, security tokens, and real-world assets) and better developer tools like an upgraded RPC and a richer 'Lab' for simulating and debugging transactions.
The strategic bet is clear: become the default settlement layer for regulated stablecoins and tokenized traditional assets. Investment is flowing into smart wallets (passkey and social-login key recovery in the Freighter wallet), the Stellar Disbursement Platform for enterprise payouts, and oracle infrastructure so DeFi can price assets on-chain.

The ecosystem
USDC by Circle — a major native stablecoin on Stellar, with Circle's CCTP V2 letting USDC move to other chains without wrapping
PayPal USD (PYUSD) — PayPal's stablecoin is live on Stellar, exposing it to a large mainstream user base
MoneyGram — cash-to-crypto on/off ramps using USDC across hundreds of thousands of physical locations; its own MGUSD stablecoin (issued via Bridge) launched in 2026
Franklin Templeton — its tokenized US government money-market fund (FOBXX / BENJI) runs on Stellar, a flagship real-world-asset use case
EURC and other regional stablecoins for euro-denominated settlement
Freighter wallet, the Stellar DEX, and a growing Soroban DeFi/oracle ecosystem (e.g., RedStone price feeds)
Core use cases: cross-border remittances, stablecoin settlement, and tokenization of funds and real-world assets
History
2014Stellar launches (July 31); Jed McCaleb and Joyce Kim found the Stellar Development Foundation, backed by a $3M Stripe loan. Initially forks the Ripple protocol.
2014December: an unintentional ledger fork exposes weaknesses in the borrowed, Ripple-derived consensus design.
2015Stellar adopts the new Stellar Consensus Protocol (SCP), designed by Stanford's David Mazières, replacing the Ripple-derived mechanism.
2017Growing adoption for cross-border payments; partnerships and pilots with payment and fintech firms expand.
2019Validators vote to end the 1%-a-year inflation (October); SDF burns ~55 billion XLM (November), cutting total supply to ~50 billion.
2021Franklin Templeton launches a tokenized US government money-market fund (FOBXX) on Stellar — an early institutional real-world-asset milestone.
2021Jed McCaleb steps away from active roles; USDC by Circle becomes a native asset on the network.
2024Soroban smart contracts go live on mainnet (Protocol 20, February); MoneyGram + Circle build a global crypto-to-cash service on Stellar.
2025'Road to 5000 TPS' scaling push; PayPal's PYUSD goes live on Stellar; real-world-asset value on the network grows sharply.
2026Circle deploys CCTP V2 to Stellar; MoneyGram launches its MGUSD stablecoin; Protocol 27 ('Zipper', smart accounts + auth delegation) goes to a mainnet validator vote around July 8.
The honest risks
Centralization concerns are the biggest and most persistent critique. The Stellar Development Foundation has historically held a very large share of XLM (roughly half the supply) and runs influential validators, giving it outsized sway over the network's direction — far from the 'trustless' ideal.
Validators earn no direct protocol reward. Without an economic incentive to run infrastructure, the validator set stays relatively small and concentrated, which weakens the practical decentralization of consensus.
XLM is a utility token, not a claim on the ecosystem's success. Even as stablecoins and tokenized funds grow on Stellar, most of that value moves in USDC/PYUSD/tokenized assets — not XLM — so real-world usage doesn't automatically translate into XLM demand or price.
Fierce competition. Stellar competes for the payments and stablecoin-settlement role against Ripple/XRP (its close cousin), plus Ethereum, Solana, Tron, and others that also court stablecoin issuers and institutions. Its edge is not guaranteed.
Slow institutional adoption. The thesis leans on banks and enterprises moving onto public rails, which historically happens slowly and can stall or route to competitors.
Regulatory exposure. Its fortunes are tied to stablecoins and tokenized securities — heavily regulated areas where rule changes could help or hurt. The nonprofit structure has so far spared it the securities fights Ripple faced, but that isn't a guarantee.
Price volatility. Like most crypto, XLM can swing hard and has spent long stretches far below prior highs; it is not a stable store of value.
How to invest (safely)
Education first, not financial advice. Understand that XLM is a volatile crypto asset and only consider money you can afford to lose entirely. Nothing here is a recommendation to buy.
Separate the tech from the token. Stellar the network can succeed at stablecoin settlement while XLM the token underperforms — be honest with yourself about which one you're actually betting on and why.
If you buy, use a reputable exchange that lists XLM, complete its verification, and start small. Compare fees and confirm the platform operates in your jurisdiction.
Move meaningful holdings to self-custody. Stellar-native wallets like Freighter (browser) or Lobstr let you hold your own keys; remember each Stellar account needs a small minimum XLM balance to stay active.
Write down your recovery phrase on paper, store it offline, and never type it into a website or share it. Anyone with the phrase controls the funds — no exchange or foundation can reverse a theft.
Send a tiny test transaction first when moving XLM to a new wallet, and double-check you're not sending to an exchange address that requires a memo/tag (a common way people lose funds on Stellar).
For larger amounts, consider a hardware wallet (e.g., Ledger) for offline key storage, and be skeptical of any 'airdrop', 'staking', or 'giveaway' site asking for your seed phrase — those are scams.
