Build, test and deploy

tBTC v2 contracts use Hardhat development environment. To build and deploy these contracts, please follow the instructions presented below.

Prerequisites

Please make sure you have the following prerequisites installed on your machine:

• Node.js >14.17.4

• Yarn >1.22.10

Build contracts

To build the smart contracts, install node packages first:

yarn install

Once packages are installed, you can build the smart contracts using:

yarn build

Compiled contracts will land in the build directory.

NOTE: The tbtc-v2 package contains an indirect dependency to @summa-tx/[email protected] package, which downloads one of its sub-dependencies via unathenticated git:// protocol. That protocol is no longer supported by GitHub. This means that in certain situations installation of the package or update of its dependencies using Yarn may result in The unauthenticated git protocol on port 9418 is no longer supported error.
As a workaround, we advise changing Git configuration to use https:// protocol instead of git:// by executing:

git config --global url."https://".insteadOf git://

Test contracts

There are multiple test scenarios living in the test directory.

You can run unit tests with:

yarn test

The tests marked as "pending" during yarn test are integration tests.

You can run integration tests with:

yarn test:integration

System tests are implemented separately, in the system-tests directory of the tbtc-v2 repository.

Deploy contracts

To deploy all contracts on the given network, please run:

yarn deploy --network <network>

If contracts haven’t been built yet or changes occurred, this task will build the contracts before running the deployment script. This command produces an export.json file containing contract deployment info.
