README

Fill.city Autobahn

Autobahn is the open source aggregator for swaps on Solana. This public good protocol enables developers to contribute their own DEX adapters. Take back control: access to orderflow from routers on Solana should not be centralized.

The graph search is optimized for reliability of trade execution. Reliability is preferred over marginal price to improve user experience. Full test coverage through daily verification of all routed pools ensures correctness.

A hosted version is available. Reach out to partnerships@mango.markets to get an access token. Self-hosting requires custom validator patches to enable low-latency account subscriptions.

Using the router (as a client)

Basically it is the same API as Jupiter: https://autobahn.mngo.cloud/<TOKEN>/

quote (GET)

Supported parameters: - inputMint - outputMint - amount - slippageBps - maxAccounts - onlyDirectRoutes

swap & swap-instructions (POST)

Supported parameters:

userPublicKey
wrapAndUnwrapSol
autoCreateOutAta
quoteResponse

Running the router

See example configuration file example-config.toml to create your own setup

Run like this:

RUST_LOG=info router my_config.toml

Creating a new DEX Adapter

Adding new DEX adapter is welcome, you can do a pull-request, it will be appreciated !

See CreatingAnAdapter.MD file for details.

Integration testing

It's possible to dump data from mainnet, and then use that in tests: - To assert quoting is correct (same result as simulated swap) - To check router path finding perfomance

See Testing.MD file for details.

There's a script for daily smoke tests:

RPC_HTTP_URL=... ./scripts/smoke-test.sh

Tokio-Console

Build router with feature tokio-console and RUSTFLAGS="--cfg tokio_unstable" like this:

RUSTFLAGS="--cfg tokio_unstable" cargo build --bin router --release --features tokio-console

And use the tokio-console crate to display running tasks
