Soroswap Finance Review: Is Its Stellar Aggregator Worth Using?

Soroswap is both a Stellar swap app and an API for developers. The aggregator routes trades across Soroswap AMM, Aquarius, Sushi, Comet and the Stellar Classic DEX. It says its engine queries venues in real time and can split an order across pools when that improves the route. That may save you from checking each venue manually, but an aggregated quote is not a guarantee of the final execution price: pool liquidity and prices can change before a trade settles.

The app is aimed at people who want to trade on Stellar. The API is for wallets, exchanges and dApps that want to add swaps for their own users. Soroswap also offers Earn through DeFindex vaults and bridging through a Rozo Pay integration. These are separate activities with different risks: a swap is not the same as depositing assets into a strategy, and bridging adds another service and transaction path. Check which product and transaction you are authorizing before signing.

For API use, the free tier allows 1 request per second; Starter allows 10, Professional 50 and Business 100. Soroswap does not publish the prices for the higher tiers. Developers can set a partner fee on swaps routed through their integration, and Soroswap keeps a share, but the fee split is not published. Confirm the commercial terms directly before building a business around that revenue.

The API plan is only one part of the cost picture. Soroswap does not publish a single swap fee schedule or a standard spread: the effective price depends on the route, pools and any fee attached to the transaction or integration. Stellar network transaction costs may also apply. The project describes trustlines as gasless through its feature, but that is not a promise that all transactions are free. Compare the quoted output with the amount you expect to receive, and read the transaction details in your wallet before approving.

Soroswap says its SDK and AMM contracts are open source, which gives developers a way to inspect some of the code. That is useful transparency, but open-source code is not the same as an independent security audit. Soroswap does not publish an audit in the details covered by its product information, and its licensing and custody arrangements are not clearly specified. Treat that as an unresolved trust question, particularly before placing assets in a vault.

A DEX aggregator generally routes transactions to on-chain venues rather than holding a conventional exchange balance for you. Still, do not assume every component is non-custodial or risk-free: check the transaction destination, contract and wallet prompts before signing. Soroswap Earn uses DeFindex vaults, which bring strategy and smart-contract risks on top of token-price risk. No yield is guaranteed. Start with an amount you can afford to lose, and review the vault’s assets, strategy and withdrawal conditions before depositing.

For a direct swap, Soroswap points users to its web app. The project describes an API, REST endpoints and a TypeScript SDK for developers, with documentation and a testnet sandbox. Its gasless trustline feature is intended to reduce the setup friction of trading Stellar assets. The app’s supported wallets, mobile experience and any geographic restrictions are not specified, so check that your wallet connects and can sign the relevant Stellar transactions before moving funds.

Developers can use REST calls from different programming stacks, or the SDK for a TypeScript integration. Soroswap says its API can build transactions and support signing flows, but you remain responsible for the security of your application and the approval experience you provide to users. The aggregator names five liquidity venues; the actual route available for a particular token pair depends on current liquidity. Bridging through Rozo Pay involves a separate integration, so check its route, fees and delivery conditions independently.

Soroswap is most compelling if you already use Stellar or are building a product that needs Stellar swaps. The API’s free tier gives developers a way to begin, and aggregation avoids writing separate integrations for each listed venue. The main limitations for a consumer are the lack of a published overall fee schedule, no clearly stated custody model, and limited public security assurances. For developers, paid API prices and the partner-fee split need confirmation before launch.

Do not treat the project’s claim of competitive routing as a guarantee that every trade will beat a direct venue. Compare the displayed output, token contract or issuer, and transaction costs for your own trade. If you are considering Earn, read the specific vault terms and understand that automated strategies can lose value. If you bridge in, check the provider and expected completion conditions. These checks matter more than a broad claim of convenience.
