Autobahn

Autobahn is an open-source Solana swap aggregator and router. It searches routes across supported liquidity sources and provides quote, swap, and swap-instructions endpoints for developers integrating swaps. Teams can use a hosted router with an access token, self-host the Rust service, or contribute DEX adapters.

Practical overview

When it fits

Use Autobahn when a Solana application needs a router to search supported DEX liquidity sources for swap routes, or when a team wants to host or extend that routing service.

Who it is for

  • Developers integrating Solana token quotes and swaps into an application.
  • Teams that want to operate a self-hosted Solana swap router.
  • Developers building adapters for additional DEX liquidity sources.

Documented uses

  • Request a quote for an input and output token with amount, slippage, and route constraints.
  • Submit swap-related requests using a public key and quote response.
  • Run a router using a local configuration.
  • Extend routing to an adapter’s supported markets.
Before you choose

Requirements & limits

The README describes a hosted version that requires an access token requested from partnerships@mango.markets. Self-hosting is also documented.

  • Route search is described as prioritizing execution reliability over marginal price.
  • The documented quote request supports mint identifiers, amount, slippage, maximum accounts, and a direct-routes constraint.
  • Swap and swap-instructions requests support a user public key, quote response, SOL wrapping options, and automatic associated-token-account creation.
  • Self-hosting requires custom validator patches for low-latency account subscriptions.
  • The project is open source under AGPL-3.0 and written in Rust.

Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.

Source-based practical guide

Start the self-hosted router from a configuration file

Create a router setup from the example configuration and start the documented Rust router process.

Before you start

  • Autobahn repository
  • Example configuration file at bin/autobahn-router/example-config.toml
  • Custom validator patches for low-latency account subscriptions

Steps

  1. Use the example configuration file to create a router configuration.

  2. Start the router with RUST_LOG=info router my_config.toml.

Expected outcome

The documented router process is started using the selected configuration.

Guide limitations

  • The README does not explain the configuration fields in detail.
  • Self-hosting requires custom validator patches for low-latency account subscriptions.
