Invariant protocol is an AMM built on Casper Network, leveraging high capital efficiency and the ability to list markets in a permissionless manner. At the core of the DEX is the Concentrated Liquidity mechanism, designed to handle tokens compatible with the Erc20 standard. The protocol is structured around a single contract architecture.

Usage

It's recommend to install:

• cargo-odra
• wasm-strip

To install wasm-strip using apt, run the following command:

sudo apt install wabt

Additionally, add the wasm32-unknown-unknown target by running:

rustup target add wasm32-unknown-unknown

Build

$ cargo odra build

To build a wasm file, you need to pass the -b parameter. The result files will be placed in ${project-root}/wasm directory.

$ cargo odra build -b casper

Test

To run tests, choose between the MockVM and Casper backend using the following commands:

Run tests on MockVM

cargo odra test

Run tests on Casper backend

To test actual wasm files against a backend, you need to specify the backend passing -b argument to cargo-odra.

cargo odra test -b casper

Typescript SDK

Utilize the Invariant SDK from the npm registry by including it as a dependency. Alternatively, for a customized approach, build the SDK on your own using the commands provided below:

To begin, navigate to the directory dedicated to the SDK

• Build SDK

./build.sh

• Run e2e tests

./test.sh
