Exsat EVM supporting contracts

This repository contains the Solidity and Antelope contracts needed to support advanced functionality of the Exsat. Including staking and reward claiming.

This repository is split from https://github.com/exsat-network/evm-bridge-contracts. The old repository would only hold trustless bridge codes and this repository would hold the code for the rest of advanced features.

Those contracts (both within solidity_contracts and antelope_contracts) enable communication and tokens moves between the EVM and Native environments.

Dependencies

• CMake 3.16 or later
• Leap 5.0 or later
• CDT 4.0 or later
• solc
  • Used to compile the .sol files.
  • We chose to use solcjs because it is more actively maintained than the solc available from the package manager.
    • First install node.js and npm.
    • Then install solcjs: npm install -g solc
  • Make sure to install at least version 0.8.21.
    • Confirm with solcjs --version.
• Install jq used to compile solidity contracts
  • apt-get install jq
• Install xxd used to compile solidity contracts
  • apt-get install xxd

Building

Update submodules by running: git submodule update --init --recursive

Create a build directory within the root of the cloned repo and cd into it.

Run cmake -Dleap_DIR="${LEAP_BUILD_PATH}/lib/cmake/leap" -Dcdt_DIR="${CDT_BUILD_PATH}/lib/cmake/cdt" .. from within the build directory. Here we assume that environment variables LEAP_BUILD_PATH and CDT_BUILD_PATH are set to the build directories for the Leap and CDT dependencies, respectively. The -Dleap_DIR and -Dcdt_DIR options are used to specify custom builds of Leap and CDT, respectively. If you have installed the appropriate version of CDT on the system, you can leave off the -Dcdt_DIR. Even if you have installed Leap binaries on the system, you will still need to build Leap and use -Dleap_DIR because the build directory contains specific testing libraries needed for building the unit tests for the bridge contracts.

Run the command make -j.

Running tests

The build steps above will build the test as well.

After building, cd into the build directory and then simply run ctest.
