"At Curve, we started exploring possibilities of launching beyond EVM chains if there is demand. Stellar looks like a good fit: it's closer to the familiar EVM world than many other chains. And at the same time, the demand for Curve is there, and it comes from institutions." — Michael Egorov, Founder, Curve Finance
Curve Finance deployed its StableSwap protocol on Stellar's mainnet on October 29, 2026, marking the $1.27 billion TVL protocol's first native deployment outside the Ethereum Virtual Machine ecosystem. The deployment, built on Stellar's Soroban smart contract platform, targets institutional stablecoin and forex trading — a market segment where the traditional foreign exchange market processes $9.5 trillion per day while on-chain forex infrastructure remains negligible at less than 0.01% of that volume.
The move is significant for two reasons. First, it signals that institutional demand is now strong enough to pull a major DeFi protocol out of its native EVM comfort zone and into a compliance-oriented network. Second, Curve's planned FXSwap module, pending audit, would create the first institutional-grade on-chain forex automated market maker on a network already handling $25.1 billion in quarterly stablecoin transfers. Stellar's existing institutional rails — including partnerships with Securitize, the DTCC, and MoneyGram — make this a deployment aimed at real settlement, not speculative volume.
Curve's StableSwap is live on Stellar mainnet at stellar.curve.finance. The deployment enables permissionless pool creation, asset swaps, and liquidity provision for closely correlated assets — primarily stablecoins pegged to the same currency. Users connect via Freighter and other Stellar-compatible wallets.
The technical implementation runs on Soroban, Stellar's Rust-based smart contract platform that compiles to WebAssembly. Soroban launched on Stellar mainnet in early 2024 and uses a conflict-free concurrency model designed to prevent transaction conflicts during execution. Curve's contracts were rewritten from Solidity/Vyper to Rust — a non-trivial engineering effort that required a full audit cycle.
StableSwap's core mechanism concentrates liquidity around expected exchange rates, reducing slippage on larger transactions. On Ethereum, this mechanism handles the majority of Curve's $56.28 million in annualized DEX fees. The Stellar version replicates this functionality natively, without cross-chain bridges.
The Stellar Development Foundation backed the deployment. SDF CEO Denelle Dixon stated: "Having one of DeFi's most trusted liquidity protocols choose Stellar for its first native deployment outside EVM shows that the network is the home for practical financial applications."
Curve already operates on more than a dozen EVM-compatible chains including Ethereum, Arbitrum, Optimism, Base, Polygon, and others. Expanding to another EVM chain would be trivial — a redeployment of existing Solidity or Vyper contracts. The decision to go non-EVM carries substantially higher development cost and signals a strategic bet on institutional flow.
Three characteristics differentiate Stellar from other non-EVM options:
Compliance infrastructure. Stellar's Protocol 25, launched in January 2026, enables zero-knowledge proof applications that allow institutions to hide transaction details while permitting auditors controlled access. This addresses a core institutional requirement that most DeFi-native chains lack.
Existing institutional presence. Stellar hosts $4.1 billion in tokenized real-world assets as of October 2026, up 548% year-over-year, placing it fourth behind Ethereum ($15.9B), BNB Chain ($6.3B), and Solana ($4.9B). The DTCC has announced plans to bring tokenized assets to Stellar in 2027. Securitize announced Stellar integration on October 28, one day before the Curve deployment.
Cross-border payment rails. Stellar's network processed $25.1 billion in stablecoin transfer volume in Q3 2026, a 121% increase quarter-over-quarter. PayPal's PYUSD and Circle's USDC both operate on the network. MoneyGram has used Stellar for remittance corridors.
By contrast, Solana's institutional presence is growing but remains concentrated in retail-facing DeFi and meme token trading. Stellar's network is smaller in raw throughput but better positioned for regulated financial product settlement.
The traditional foreign exchange market averages $9.51 trillion in daily turnover, according to the Bank for International Settlements' 2025 Triennial Survey. London handles 38% ($2.85T/day), New York 19% ($1.43T/day), Singapore 9% ($675B/day). FX swaps dominate at 51% of total volume, and algorithmic trading accounts for 92% of transactions.
Curve's FXSwap module, pending audit completion, targets a specific niche within this market: low-slippage conversion between stablecoins pegged to different national currencies. On Ethereum, Curve already handles same-currency stablecoin swaps (USDC/USDT, for example). FXSwap extends this to cross-currency pairs — such as USD-pegged stablecoins against euro-pegged stablecoins.
The addressable market on-chain is currently small. The entire on-chain forex market represents less than $1 billion in daily volume. But the structural logic is straightforward: if institutions are already settling stablecoin transactions on Stellar rails, they need efficient conversion between currency-denominated stablecoins. FXSwap would provide that conversion layer without requiring off-chain forex intermediaries.
The economic value proposition is clear: each forex conversion that occurs on-chain rather than through a traditional FX desk generates fees for liquidity providers and the protocol, while reducing settlement time from T+2 to near-instant. For a protocol generating $60 million in annualized fees, capturing even a fraction of forex flow could meaningfully alter Curve's revenue trajectory.
For on-chain forex to work, both sides of the currency pair need liquid stablecoins. This is the binding constraint.
USD-pegged stablecoins dominate 99% of the $308 billion stablecoin market as of August 2026. The entire euro stablecoin ecosystem totals approximately €807 million as of October 28, 2026 — less than many individual altcoin market capitalizations. EURC, issued by Circle, leads with roughly €474 million and 58% market share among euro stablecoins.
Non-USD stablecoins have grown 3.54x over three years, but from an extremely low base. The regulated euro stablecoin market grew 128% to $674 million by June 2026, driven partly by MiCA regulatory clarity in Europe. Eight euro stablecoins now report market data, up from five at the start of the year.
Stellar's own stablecoin market is approximately $394 million, heavily concentrated in USDC. For FXSwap to generate meaningful volume on Stellar, euro, yen, pound, and other currency-denominated stablecoins need to achieve significantly greater liquidity on the network.
This is a chicken-and-egg problem. Institutional demand for on-chain forex conversion could drive non-USD stablecoin issuance, but without existing liquidity, institutions have limited incentive to move forex settlement on-chain. Curve's FXSwap could serve as the conversion layer that catalyzes this flywheel — or it could sit idle waiting for non-USD stablecoin supply that takes years to materialize.
The Curve deployment does not exist in isolation. Stellar has assembled a series of institutional partnerships in rapid succession:
| Date | Partner | Development | |------|---------|-------------| | Oct 28, 2026 | Securitize | Announced integration for tokenized financial products on Stellar | | Oct 2026 | DTCC | Plans to bring tokenized assets to Stellar in 2027 | | Q3 2026 | U.S. Bank | Completed live USBDC cross-border pilot between North America and Europe | | Jan 2026 | Protocol 25 (X-Ray) | Zero-knowledge proof privacy tools for institutional compliance | | Ongoing | Circle, PayPal | USDC and PYUSD live on Stellar |
The Securitize announcement is particularly relevant to the Curve deployment. Securitize, now a publicly listed company, manages tokenized assets for major institutional issuers including BlackRock. Its integration with Stellar means tokenized fund shares and other assets could eventually be traded against stablecoins in Curve pools — creating a direct link between DeFi liquidity infrastructure and institutional tokenized assets.
Stellar's total tokenized RWA value of $4.1 billion, combined with $25.1 billion in quarterly stablecoin volume, creates a baseline of institutional activity that Curve can serve. The question is whether this baseline converts into meaningful DEX volume.
Curve Finance generates approximately $60.5 million in annualized fees and $28.4 million in annualized revenue across all chains, with Ethereum accounting for $1.224 billion of the protocol's $1.27 billion TVL. The protocol has experienced a steady TVL decline from $1.98 billion in January 2026 to $1.27 billion in October, mirroring broader DeFi compression.
The Stellar deployment represents a new revenue channel, but expectations should be calibrated. Curve's non-Ethereum deployments collectively hold approximately $46 million in TVL — less than 4% of the total. No individual non-Ethereum chain contributes meaningfully to protocol revenue today. Fraxtal holds $9.8 million, Monad $9.73 million, and most other chains hold single-digit millions.
For Stellar to become more than a marginal contributor, it needs to attract institutional liquidity providers willing to deploy capital into StableSwap and eventually FXSwap pools. The Securitize partnership, DTCC plans, and U.S. Bank pilot suggest the institutional user base exists. Converting that user base into active DeFi liquidity provision is the unproven step.
Curve's fee structure charges a small percentage on each swap, split between liquidity providers and the protocol. At Stellar's current stablecoin volume of approximately $8.4 billion per month, even capturing 1% of that flow through Curve pools would generate roughly $84 million in monthly swap volume — potentially adding several hundred thousand dollars in annualized fees to the protocol.
Non-USD stablecoin liquidity. FXSwap's utility depends on non-USD stablecoins achieving critical mass on Stellar. Current euro stablecoin supply on the network is not publicly broken out but is likely a small fraction of the $394 million total.
Competition. Other DEX protocols could deploy to Stellar. The first-mover advantage is real but not permanent.
Regulatory uncertainty. On-chain forex trading between regulated stablecoins in multiple jurisdictions creates complex regulatory questions that remain unresolved.
TVL migration. Curve has not demonstrated an ability to attract significant TVL on non-Ethereum chains. The same pattern could repeat on Stellar.
Soroban maturity. Stellar's smart contract platform is relatively new compared to the EVM ecosystem. Smart contract risk is higher on a less battle-tested platform, despite the Rust/Wasm security advantages.
Curve's Stellar deployment is a structural bet on institutional on-chain forex — not a liquidity grab. The protocol is trading EVM convenience for a compliance-grade network where regulated institutions already operate. The economic logic is sound: if stablecoin settlement moves on-chain, the conversion layer between currencies captures value at every turn.
The risk is timing. Non-USD stablecoin supply remains orders of magnitude below what is needed for institutional forex settlement. FXSwap could launch to a market that does not yet exist at scale. But the pieces are assembling: Securitize for tokenized assets, Protocol 25 for privacy, the DTCC for securities settlement, and now Curve for liquidity. Whether these pieces combine into a functioning institutional DeFi stack on Stellar — or remain a collection of announcements — will depend on actual capital deployment over the next 12 months.
