You can use the following SDKs to integrate with the Express Relay APIs and contracts:
pre-commit is a tool that checks and fixes simple issues (formatting, ...) before each commit.
You can install it by following their website.
In order to enable checks for this repo run pre-commit install from command-line in the root of this repo.
The checks are also performed in the CI to ensure the code follows consistent formatting.
Since express relay is a multi-service project, we use Tilt to manage the development environment.
It is a great tool for local development and testing.
Tilt requires anvil, forge, poetry, and rust to be installed on your machine.
Here are the installation instructions for each:
- Rust: https://www.rust-lang.org/tools/install
- Foundry (anvil,forge,cast, etc.): https://book.getfoundry.sh/getting-started/installation
- Poetry: https://python-poetry.org/docs/#installation
- Tilt: https://docs.tilt.dev/install.html
Run tilt up in the root of the repo to start the development environment.
You can access the ui at http://localhost:10350/.
Here is what tilt up does in order:
- Starts
anvil: local EVM chain to test the contracts with - Deploy express relay contracts
- Start the auction server
- Start the liquidation monitor
- Start the simple searcher
There are some useful gadgets in Tilt ui for creating new vaults and checking the vault status. You can use them to test the system end to end.
You can modify the services and restart the resources as necessary.
