Aggregator v3 is the contract the Soroswap API settles every Soroban swap through on mainnet. It runs typed routes hop by hop across Soroswap, Aquarius, SushiSwap V3, Comet and Phoenix. There is no adapter registry: each venue is compiled into the contract, and callers name the pools in each hop.

Aggregator v3

Entrypoints, route and hop types, fees, errors and events.

Cross-Contract Integration

Calling v3 from your own contract, with a mainnet example.

Deprecated: the adapter-based aggregator

The original aggregator, CAYP3UWLJM7ZPTUKL6R6BFGTRWLZ46LRKOXTERI2K6BIJAWGYY62TXTO, reached each protocol through an adapter contract (Soroswap, Phoenix, Aqua and Comet). The API stopped using it on 2026-09-24. These pages are kept for reference:

SoroswapAggregator

Registry, distribution, and the two swap functions.

Adapter Trait

The interface every adapter implements.

SoroswapAdapter

The adapter that reaches the Soroswap AMM router.
