Lyra Cockpit

Client / SDK for Lyra Exchange, types, automated trading algorithms, vault executors, and more.

1. Installation

Currently, the binary needs to be compiled from source.

git clone https://github.com/lyra-finance/cockpit.git
cd cockpit
# if cargo is not installed:
# curl https://sh.rustup.rs -sSf | sh
cargo build --release

2. Environment

Every binary from the repo (e.g. a CLI) expects a set of environment variables to be set, such as public / private keys. There are two ways of setting them:

1. Create a .env.keys.staging and/or .env.keys.prod files and fill them with the env variables below.

SESSION_PRIVATE_KEY=0x0000000000000000000000000000000000000000000000000000000000000000
OWNER_PUBLIC_KEY=0x0000000000000000000000000000000000000000

Make sure to never commit the secretes to the repo! The .env.keys.* patterns is present in .gitignore already.

2. Set the environment variables via AWS parameter store using the following path rules:

• Add SESSION_KEY_NAME and OWNER_KEY_NAME to the .env files (e.g. .env.keys.staging or .env.keys.prod)

SESSION_KEY_NAME=alice_session
OWNER_KEY_NAME=bob_owner

• Use the following paths for the AWS parameter store:
  • "/session_keys/prod/{}" or "/session_keys/staging/{}" for SESSION_PRIVATE_KEY where {} is the key name ( e.g. "/session_keys/prod/alice_session")
  • "/owners/prod/{}" or "/owners/staging/{}" for OWNER_PUBLIC_KEY where {} is the key name ( e.g. "/owners/prod/bob_owner")

The parameters should use a secret string type.

3. Build

• cargo build --release to build the release binary
• cargo build to build the debug binary

4. Run CLI

The CLI is one of the several apps built by the repo. It supports sending API requests to the Lyra Exchange.

Commands

To run an API RPC request (e.g. sending an order or getting ticker), two approaches are supported:

• Create a JSON file with rpc_params.json name and place the request parameters there. For example, to call public/get_ticker, the following json will work:

{
  "instrument_name": "ETH-PERP"
}

• Then call the CLI using target/release/lyra-client rpc -m public/get_ticker -f rpc_params.json
• Alternatively the json string can be supplied via --inline or -i parameter: target/release/lyra-client rpc -m public/get_ticker -i '{"instrument_name": "ETH-USDC"}'

The CLI also supports printing orderbook for any instrument (even if not supported by the Lyra UI):

• target/release/lyra-client orderbook -i ETH-USDC
