Stellar

Circle, the company behind USD Coin (USDC), has made Stellar one of its core blockchain deployments for the world's largest regulated&nbsp;<a href="https://bsc.news/post/understanding-stablecoins-how-they-work-guide" rel="noopener noreferrer nofollow">stablecoin</a>. The decision comes down to three concrete factors: Stellar's sub-5-second transaction finality, fees that cost a fraction of a cent, and a network built from the ground up for cross-border payments rather than retrofitted for them later.
<h2 id="span-span-strong-what-is-stellar-and-why-does-it-matter-for-stablecoins-strong-span-span">What Is Stellar, and Why Does It Matter for Stablecoins?</h2>
Stellar is a public blockchain co-founded by Jed McCaleb in 2014. It was built with one primary goal: moving value across borders quickly and cheaply, with a particular focus on users who lack access to traditional banking.
Unlike&nbsp;<a href="https://bsc.news/post/what-is-bitcoin-how-it-works-mining-digital-gold-guide" rel="noopener noreferrer nofollow">Bitcoin</a> or&nbsp;<a href="https://bsc.news/post/what-is-ethereum-eth-how-it-works-explained" rel="noopener noreferrer nofollow">Ethereum</a>, Stellar does not use proof-of-work or proof-of-stake to confirm transactions. Instead, it runs on the&nbsp;Stellar Consensus Protocol (SCP), a type of&nbsp;Federated Byzantine Agreement (FBA). In plain terms, each node on the network selects a set of other nodes it trusts, and a transaction is confirmed once enough of those trusted nodes agree on its validity. There is no mining, no energy-intensive computation, and no block reward system — just fast, deterministic settlement.
Key network characteristics as of 2025/2026:
<ul>
 <li>Transaction finality in 3–5 seconds</li>
 <li>Base transaction fee of 0.00001&nbsp;<a href="https://bsc.news/post/stellar-xlm-token-explained" rel="noopener noreferrer nofollow">XLM</a> (fractions of a cent)</li>
 <li>99.99% uptime over the network's operational history</li>
 <li>Protocol 23, rolled out in late 2025, introduced parallel transaction processing, pushing theoretical throughput toward 5,000 transactions per second</li>
</ul>
These specs make Stellar a natural fit for a stablecoin meant to function like cash.
<h2 id="span-span-strong-how-did-usdc-come-to-stellar-strong-span-span">How Did USDC Come to Stellar?</h2>
Circle first announced Stellar as an official USDC chain in late 2020, through the Centre Consortium — the joint governance body it operated with Coinbase. Full API and business account support rolled out by Q1 2021. In August 2023, Circle and Coinbase dissolved the Centre Consortium entirely, and Circle took over all USDC governance and operations in-house.
The Consortium recognized Stellar's strong track record in payment corridors, particularly in Latin America and Africa, and its clearly payment-oriented developer community.
Minting USDC natively on Stellar required custom engineering. Stellar's default asset model only allows the original account that created an asset to issue more of it. That design did not work for USDC, which requires multiple authorized minting entities to maintain its full-reserve model — one dollar held in reserve for every one USDC in circulation. Circle had to build around Stellar's native architecture rather than simply plug in.
As of mid-2026, approximately $180.7 million in USDC is in active circulation on Stellar, accounting for roughly 0.23% of total USDC supply across all blockchains.&nbsp;
<h2 id="span-span-strong-why-did-circle-add-cctp-to-stellar-strong-span-span">Why Did Circle Add CCTP to Stellar?</h2>
The next major step came on May 19, 2026, when Circle activated its&nbsp;Cross-Chain Transfer Protocol (CCTP) on Stellar. The Stellar Development Foundation announced the integration, which connects Stellar to 23 other blockchains including Ethereum,&nbsp;<a href="https://bsc.news/post/solana-blockchain-ecosystem-deep-dive" rel="noopener noreferrer nofollow">Solana</a>,&nbsp;<a href="https://bsc.news/post/avalanche-deep-dive-technical-ecosystem-analysis" rel="noopener noreferrer nofollow">Avalanche</a>,&nbsp;<a href="https://bsc.news/post/arbitrum-ethereum-layer-2-analysis" rel="noopener noreferrer nofollow">Arbitrum</a>, and Base.
CCTP uses a&nbsp;burn-and-mint mechanism. When a user moves USDC from Stellar to Ethereum, for example, the Stellar-side USDC is permanently destroyed, Circle's off-chain Iris attestation service cryptographically signs the burn event, and a matching amount of fresh, native USDC is minted on Ethereum.&nbsp;
The total USDC supply across all chains stays constant. There is no wrapped token, no liquidity pool held by a third party, and no bridge vault that could be targeted by an attacker.
Jonathan Lim, Principal Product Manager at Circle, explained:&nbsp;
"Traditional cross-chain flows are often riddled with additional trust assumptions, block-finality delays, and liquidity fragmentation. CCTP V2 mitigates these issues, and paves the way for improved cross-chain USDC liquidity, enhanced cross-chain UX, and institutional-grade cross-chain infrastructure."
Cross-chain transfers through CCTP on fast-finality networks like Stellar typically settle in under 60 seconds. CCTP V2 also added&nbsp;programmable post-transfer hooks, which let developers trigger automatic actions, such as swapping assets or depositing into a lending protocol, the moment USDC arrives on the destination chain. This removes the need for a separate manual step after a cross-chain transfer.
<h2 id="span-span-strong-what-does-the-on-chain-data-actually-show-strong-span-span">What Does the On-Chain Data Actually Show?</h2>
Range Security, a blockchain intelligence firm, analyzed USDC activity on Stellar between September 2024 and September 2025. The numbers describe a network being used for everyday, practical payments rather than speculative trading.
Across that period:
<ul>
 <li>91.3 million USDC transactions recorded on Stellar</li>
 <li>Total volume reached $17.9 billion</li>
 <li>Median transaction size was just 1.57 USDC</li>
</ul>
A median of 1.57 USDC means the bulk of Stellar's USDC activity consists of microtransactions, small peer-to-peer and business payments, not large institutional flows or DeFi arbitrage. Transaction activity peaks between 14:00 and 15:00 UTC, consistent with working hours across Europe and the Middle East, pointing to real-world payment corridors rather than automated bot activity.

<h3 id="span-span-strong-humanitarian-aid-at-scale-strong-span-span">Humanitarian Aid at Scale</h3>
The UNHCR (United Nations High Commissioner for Refugees) uses Stellar to deliver USDC directly to displaced people through a program called Stellar Aid Assist.&nbsp;
Recipients receive USDC in a Vesseo digital wallet on their smartphone. They can then cash out at participating MoneyGram locations across approximately 150 countries, without needing a bank account. The UNHCR has deployed this in contexts including Ukraine, where bulk USDC disbursements replaced slower, more expensive traditional aid transfer methods.
<h3 id="span-span-strong-remittances-without-a-bank-account-strong-span-span">Remittances Without a Bank Account</h3>
MoneyGram has&nbsp;<a href="https://bsc.news/post/moneygram-stellar-partnership-stablecoin" rel="noopener noreferrer nofollow">integrated</a> Stellar's rails to allow users to convert cash to USDC and back at participating locations worldwide. MoneyGram's overall retail network spans nearly 500,000 locations globally, serving more than 60 million active customers.&nbsp;
For families in Nigeria, Mexico, or the Philippines receiving money from relatives abroad, this means near-instant settlement at a cost that significantly undercuts traditional remittance providers. Traditional services like Western Union typically charge 5–7% per transfer and can take days; Stellar transactions cost fractions of a cent and settle in seconds.
More recently, MoneyGram launched its own native Stellar stablecoin, MGUSD, in mid-2026 — signaling how deeply the company has committed to Stellar as its settlement infrastructure.
<h3 id="span-span-strong-institutional-settlement-strong-span-span">Institutional Settlement</h3>
IBM's World Wire platform was built on Stellar and supported cross-border settlements in more than 50 countries at its peak, working with banks including Banco Bradesco, Bank Busan, and RCBC. It demonstrated early on that enterprise-scale financial institutions could use Stellar's rails for real-money settlement.&nbsp;
More recently, PayPal launched its PYUSD stablecoin on Stellar in June 2025, and Mastercard has partnered with the network on its Crypto Credential infrastructure.
<h2 id="span-span-strong-is-stellar-competing-with-ethereum-for-usdc-volume-strong-span-span">Is Stellar Competing With Ethereum for USDC Volume?</h2>
Not directly, and that is by design. Stellar and Ethereum serve different purposes within Circle's multi-chain USDC strategy.
As of April 2026, USDC's total supply across all chains exceeded $78.1 billion, with roughly $2.4 billion moved through CCTP in March 2026 alone. USDC is now natively supported on 34 blockchain networks, according to Circle's official documentation as of May 2026. Ethereum dominates DeFi volume; Stellar handles payments and remittances at the lower-value, higher-frequency end of the market.
The activation of CCTP on Stellar means those two segments are now directly connected. A user can receive USDC via a low-cost Stellar payment corridor, then move it to Ethereum for DeFi applications, all without touching a third-party bridge or holding a wrapped token at any point.
<h2 id="span-span-strong-conclusion-strong-span-span">Conclusion</h2>
Stellar's case for USDC deployment is built on a specific set of infrastructure characteristics. Its Federated Byzantine Agreement consensus delivers 3–5 second finality at near-zero cost. Its decade-long focus on payment corridors gave it real, measurable adoption in emerging markets before most DeFi chains existed.
The 91.3 million USDC transactions recorded between September 2024 and September 2025, with a median size of 1.57 USDC, show a network functioning as its founders intended. And the addition of CCTP on May 19, 2026, removed the last significant limitation, the isolation of Stellar's USDC liquidity from the broader multi-chain ecosystem. Stellar now functions as both a standalone payment rail and a connected node in a 23-chain USDC network.
