The nonprofit quietly building the plumbing under global money

Most blockchains were built to make somebody rich. Stellar was built to make a $50 remittance cost a fraction of a cent. That difference in ambition explains almost everything about the Stellar Development Foundation - a San Francisco nonprofit that writes open-source code, gives away money to people who build on its network, and spends a surprising amount of time talking to regulators. It is one of the least flashy organizations in crypto, and one of the more consequential.

Founded in 2014 by Jed McCaleb and Joyce Kim, the Foundation stewards Stellar, an open-source, layer-1 blockchain designed around a single verb: move. Move dollars into euros. Move cash into digital dollars. Move a tokenized Treasury bond from one wallet to another. The network settles those transfers in under five seconds, for fees measured in tiny fractions of a cent, without mining a single block.

What it actually does

The Foundation, known as SDF, does three things. It maintains the Stellar codebase and shepherds protocol upgrades. It funds the ecosystem of developers, fintechs, and companies building on the network through grants and matching investments. And it acts as a voice to institutions and regulators - a role most crypto projects avoid. The network itself is owned by no one; SDF is the nonprofit that keeps it healthy.

Stellar is two things at once: a cross-currency transaction system and a platform for issuing digital assets. A business can mint a regulated stablecoin, a bank can tokenize a fund, and a remittance company can route a payment across currencies - all on the same public ledger. That combination, payments plus issuance, is the core of the pitch.

The founder with an unusual resume

Jed McCaleb has a habit of building things that outgrow him. He created eDonkey, one of the largest file-sharing networks of its era. He built Mt. Gox, the first Bitcoin exchange. He co-founded Ripple. After a strategic split from Ripple, he and Joyce Kim - a lawyer turned entrepreneur - started Stellar in 2014 with a narrower, more stubborn goal: make international payments faster, cheaper, and open to people the banking system tends to skip.

To make it work, they recruited David Mazieres, a Stanford cryptography professor, who became chief scientist and designed the Stellar Consensus Protocol. SCP reaches agreement without proof-of-work by letting each participant choose whom it trusts - a "reconfigurable trust model." The whitepaper landed in April 2015; the upgraded network went live that November.

Who uses it

The customers fall into layers. Developers and fintechs build wallets, anchors, and on/off-ramps. Remittance companies move money. Asset issuers mint stablecoins and tokenized funds. NGOs deliver aid. And at the far end sit ordinary people - someone in Colombia cashing out digital dollars, or a displaced family receiving relief funds through a Stellar-based wallet. The network reaches end users mostly through partners; MoneyGram alone touches 50 million customers across more than 200 countries.

The MoneyGram bet

In 2022, MoneyGram plugged its physical footprint into Stellar. The mechanics are simple to describe and hard to build: a person walks into a MoneyGram location, hands over cash, and receives USDC settled on Stellar in under five seconds - or the reverse, converting digital dollars back to local cash at the counter. The partnership has since moved billions in USDC volume, and in 2026 the two extended it into a sixth year and expanded across Latin America.

When Wall Street showed up

The more surprising adopters wear suits. Franklin Templeton issued its BENJI tokenized money market fund on Stellar - among the first U.S.-registered funds to live on a public blockchain - with more than $580 million in tokenized Treasuries. PayPal brought its PYUSD stablecoin to the network. Circle's USDC and EURC run natively. WisdomTree and Ondo build real-world-asset products in the same ecosystem. For a chain built for the unbanked, the institutional interest is a plot twist.

The problems it solves

Cross-border payments are slow and expensive because they pass through a chain of correspondent banks, each taking time and a cut. Stellar collapses that chain into one open ledger where any two assets can be exchanged directly, with the network's native asset, Lumens (XLM), acting as a bridge currency when a direct market is thin. The result is settlement in seconds instead of days, and fees small enough that micro-remittances actually make sense.

Soroban, and smart contracts for money

For most of its life, Stellar deliberately did less than chains like Ethereum - no general smart contracts, just fast, cheap payments. That changed in 2024, when the Protocol 20 upgrade brought Soroban to mainnet. Soroban is Stellar's smart contract platform, written in Rust and executed in WebAssembly, built specifically for financial applications with predictable fees. It lets developers program the logic around a payment - escrow, lending, programmable stablecoins - without giving up the speed and cost Stellar is known for.

How the money works

SDF is a nonprofit, and its business model is unusual: it was funded at launch with an endowment of Lumens, and it spends that endowment down to develop the protocol and grow the ecosystem. Rather than charging for the network, it gives money away - a $30 million Matching Fund that co-invests alongside venture backers, a $100 million pool to seed Soroban adoption, and ongoing grants through the Stellar Community Fund. The bet is that a bigger, healthier ecosystem is worth more than any fee it could collect.

Where it sits in the market

Stellar's most direct rival is Ripple and its XRP network, born from the same founder and the same idea - fast cross-border settlement. Beyond that, it competes with stablecoin rails and with general-purpose chains like Ethereum, Solana, and Avalanche for stablecoin issuance and tokenized assets. And in the background sits the incumbent it was built to route around: SWIFT and the correspondent banking system. Stellar's differentiator is focus - payments first, compliance-friendly, cheap - rather than trying to be a world computer.

Milestones

The quiet part

There is a case to be made that Stellar's most valuable decision was the least exciting one: choosing to engage regulators rather than dodge them. In a market repeatedly bruised by collapses, a payments network that institutions can adopt without holding their breath is a real asset. It won't trend. It does help explain why a money market fund and a public-company stablecoin ended up on the same chain as humanitarian aid.
