Curve on Stellar: What StableSwap Means for Stablecoins

One of DeFi's longest-running liquidity protocols has taken its first step beyond Ethereum-compatible chains. On October 29, 2026, Curve Finance announced that its StableSwap automated market maker is live on Stellar mainnet, rebuilt from scratch for Stellar's Soroban smart-contract platform, according to the Curve team's official announcement.

• What launched: Curve StableSwap on Stellar mainnet, with a beta interface for swaps and deposits
• Milestone: Curve's first deployment on a chain outside the EVM, built with support from the Stellar Development Foundation
• Built for: pairs that should trade near the same price, such as two dollar stablecoins
• Next up: FXSwap for pairs like a dollar stablecoin against a euro stablecoin, once its audit is complete

What Is Curve StableSwap?

StableSwap is the pool design Curve has run on Ethereum since 2020. Instead of spreading liquidity across every possible price, it concentrates liquidity tightly around the price two assets are supposed to share. For a swap between two dollar stablecoins, that means trades settle close to one-for-one, even at size, with less value lost to slippage than in a general-purpose pool.

Because Stellar does not run the Ethereum Virtual Machine, Curve could not simply redeploy its Vyper contracts. The team rewrote StableSwap for Soroban while keeping the underlying math unchanged.

Why Did Curve Choose Stellar?

According to Curve, the Stellar Development Foundation invited the deployment, and the demand is coming from institutions. That fits Stellar's profile. The network has carried payments since 2014, hosts Franklin Templeton's tokenized money market fund, and is used daily by MoneyGram for cross-border transfers. Issuers on Stellar can keep an asset fully open or enable compliance controls such as KYC and clawback, which makes it a natural home for regulated stablecoins and tokenized funds.

What those assets have lacked is deep onchain venues for trading against each other. Curve says it plans to work with the foundation to build stronger stablecoin markets, and calls Stellar its only non-EVM focus for the foreseeable future.

What Does Curve on Stellar Offer Users?

Curve outlines benefits for several groups:

• Traders: near one-for-one swaps between same-peg stablecoins with low slippage
• Liquidity providers: earn a share of swap fees on stablecoins that would otherwise sit idle
• veCRV holders: fees on Stellar flow to the Curve DAO just like on other deployments
• Issuers: a deep pool gives holders a fair exit and gives lending apps a liquidation venue, making an asset easier to accept as collateral

Pool creation is permissionless, and Curve says it will help issuers launch pools before that feature reaches the interface. The team also notes the usual caveats: pools carry smart contract risk and depeg risk.

The Data-Driven Takeaway

The interesting signal is architectural. Stablecoin growth is increasingly happening on payment-focused networks rather than only on Ethereum, and liquidity infrastructure is following. A proven AMM design arriving natively on Stellar, with a currency-pair FX pool already in the pipeline, could make onchain currency conversion noticeably cheaper for the institutions already building there, including projects like the MoneyGram USD stablecoin on Stellar and U.S. Bank's stablecoin pilot.
