Curve Finance launched its StableSwap decentralized-exchange technology on the Stellar mainnet on October 29, 2026, marking the protocol’s first native deployment on a network outside the Ethereum Virtual Machine ecosystem.
StableSwap is live, while the interface remains in beta
Curve’s official launch announcement says users can browse pools, swap supported assets and supply liquidity through stellar.curve.finance. The interface is currently presented as a beta product, with a broader self-service pool-creation interface among the planned enhancements.
StableSwap is designed for assets expected to trade at similar values, such as two dollar-denominated stablecoins. Its specialized pricing mechanism seeks to reduce slippage around a peg, although liquidity conditions and changes to an asset’s value still affect the outcome of a trade.
A different smart-contract environment
Curve first built its technology around Ethereum and later deployed across several EVM-compatible chains. Stellar uses Soroban for smart contracts instead, so its contracts could not simply be copied across unchanged.
The team says it rebuilt the relevant StableSwap components specifically for Soroban with support from the Stellar Development Foundation. The integration therefore represents a technical port and adaptation rather than simply switching on an existing Ethereum deployment.
FXSwap requires further review
Curve also plans to introduce FXSwap on Stellar for assets whose prices move relative to one another, including stablecoins pegged to different national currencies. Unlike StableSwap’s near-peg model, FXSwap is designed for exchange rates that fluctuate between two assets.
The company says FXSwap development is approaching completion but an audit is still required. It did not give a confirmed launch date or list of initial trading pairs. Readers should not confuse the future product with the StableSwap functionality already available.
What users and issuers should watch
A new liquidity venue could help Stellar token issuers and payment applications move between supported stablecoins and other tokenized assets. The benefit depends on actual pool depth, adoption and integration by other applications.
Users who supply liquidity can experience smart-contract exploits, changing exchange rates or stablecoin depegs. A live protocol does not guarantee liquidity or protection from losses. Curve said it expects to concentrate on developing Stellar’s stablecoin ecosystem rather than immediately pursuing additional non-EVM integrations.
BlockBriefing has also reported on MetaMask’s October 29 Stellar integration, a separate wallet development.
